8 General Information Timers Timer-related terminology What is a timer? The timer is a relay having such an output (with or without contact) which electrically closes (turns ) or opens (turns ) the circuit after a preset time elapses when electrical or mechanical input is given. On-delay Operation (Time delay operation) The on-delay operation is an operation to give output when preset time expires after a predetermined input is given to the power supply circuit or input circuit. On-delay operation includes power supply on-delay operation and signal ondelay operation. Example of power supply on-delay operation Power supply Output signal (Time delay contact) (In time delay operation) time Off-delay Operation (Time delay resetting) The off-delay operation is an operation to turn output when preset time expires after a predetermined input is given to the power supply circuit or input circuit, and at the same time output signal is given and predetermined input is turned. Off-delay operation includes power supply off-delay operation and signal off-delay operation. Example of power supply off-delay operation Power supply (In time delay operation) Output signal (Time delay contact) Flicker Operation The flicker operation is an operation to repeat output / action according to preset time and time while a predetermined input is given to the power supply circuit or input circuit. Flicker operation includes -start flicker operation and -start flicker operation. Example of -start flicker operation t < t Power supply or signal Output signal (Time delay contact) t t time t t t : Output time t : Output time t Star ( )/Delta (g) Operation This operation controls the time in the star connection used for star-delta starting which is conducted for starting a cage induction motor and the time for switching the star connection over to delta connection. Power supply Star side contact Delta side contact t t t : Star operation time t : - Star/Delta switching time t : Delta operation time t Preset Time The preset time is the control time set by setting time-variable timer. Time The operating time means the time which elapses between the addition of predetermined input to the power supply circuit and input circuit and the completion of operation for preset time. Hold Time It means the time which elapses between the completion of operation for preset time and the start of resetting. Pause Time It means the time elapses between the start of operation for preset time and the addition of input required again for the power supply circuit or input circuit. Timer does not perform normal function unless this pause time is set longer than the timer reset time. ting It means that the operation returns to the state before starting while the timer is in operation for preset time or after it completes the operation for preset time. ting during the operation for preset time is referred to as halfway resetting. Time It means the time elapses between shutoff of input to the power supply circuit or input of reset signal and the completion of resetting. Timer resetting function shares the reset of contact, reset of mechanical parts such as pointer etc., reset of parts in internal circuit such as capacitor etc., and the value at which all of these parts complete their resetting operation is regarded as reset time. If timer is used for a pause time shorter than specified reset time, the operation time expires earlier than preset, unexpected instantaneous operation takes place or the operation is failed, thus making it impos- sible to expect the normal operation. Therefore, be sure to set the timer pause time longer than the specified reset time. Power supply (Input signal) Time delay contact Internal mechanism Internal circuit Power application time (Input signal application time) time Hold time Pause time time Minimum Power Application Time It means the minimum time during which power must be supplied in order to operate timer normally, in the case of power supply off-delay timer. Fluctuation of Time It means the irregularity in operating time caused when timer is set at specified time and the operation is repeated under the same conditions. It is also referred to as repetitive error. Voltage Error It means the difference between the operating time at the rated and that within the allowable range. Temperature Error It means the difference between the operating time at the temperature of ± C and that within the allowable temperature range. Set Error It means the difference between the set time and the time which actually elapses. It is also referred to as setting error. The set error of an analog timer is the rate to the full-scale value. If the set error is ±%, it becomes equivalent to an error of maximum ± hours on the assumption that hours is set in the range of hours. The error produced when hours is set is also equivalent to an error of maximum ± hours. As far as the set error is concerned, digital timer is by far exact. Select a digital timer for the case when accuracy is required. When using an analog type multi-range timer for setting of long time, the setting procedure stated as follows minimizes the error. For example, if you want to set hours in the range of hours, first set the pointer to such a graduation where the actual operating time should become as close to seconds as possible in the range of seconds. Then, reset the range to hours, leaving the pointer set at the graduation as it is.

9 General Information Timers Pause Time Error It means the difference between the operating time to a fixed pause time and the operating time to a pause time that varies. The pause time characteristics are the main characteristics of CR timer (timer exploiting charge and discharge of capacitor C and resistance R). If the oscillation count timer (timer which comprises an oscillation circuit composed of CR and quartz and is operated by a counting circuit inside IC or micro-computer which counts the reference signal) is used, the pause time error becomes almost negligible owing to its principles of operation. Accordingly, the description about these characteristics may be omitted for the oscillation count timer. Equation for Each Error and Measurement Conditions The operation time shall be measured, in principle, for retention time of. second and halt time of second. The measurement shall be repeated five times except for the initial test. The equation for each error and the measurement conditions are shown in the table below: TM: Ts: TMs: Tmax: Tmin: TMx : TMx : TMx : Item () Fluctuation in operation time () Voltage error () Temperature error () Set error () Pause time error Equation Tmax.

Note : If no question arises from evaluation results, - C is acceptable. Note : The measurement may be performed in other specified ranges. Note : The measurement may be performed in other specified temperature ranges. Average of measured values for operation time Set value Full-scale value. For digital timers, any arbitrary scale-value may be used. Maximum of measured values for operation time Minimum of measured values for operation time Average of operation time at such as maximizes deviation from TM in allowable range Average of operation time at such temperature as maximizes deviation from TM in allowable temperature range Average of operation time at such pause time (in the range from the specified reset time to hour) as maximizes deviation from TM Functional Vibration Resistance Means such a vibration as occurs in the range where the contact closed with that vibration during the use of the timer remains closed for the specified time ( or msec.) minimum. Destructive Vibration Resistance Means such a vibration as occurs in the range where no part is damage with that vibration during the transportation or use of the timer and the operation characteristics are maintained. Functional Shock Resistance Means such a shock as occurs in the range where the contact closed with that shock during the use of the timer remains closed for the specified time ( ms) minimum. Destructive Shock Resistance Means such a shock as occurs in the range where no part is damaged with that shock during the transportation or use of the timer and the operation characteristics are maintained. Mechanical life Means the durability that is achieved when the control output is performed in the noload state. Electrical life Means the durability that is achieved when the specified and current loads are individually applied to the control output while being turned and. Generally, the life of the timer is represented by the number of times the control output is performed. When a load is connected to the control output, the term of electrical life is used. When no load is connected to the control output, the term of mechanical life is used. The electrical life is shorter than the mechanical life, and becomes longer as the load decreases. The life of the timer is made longer by connecting a relay or a similar part rather than directly switching a large load with the control output. Rated power consumption Means the power that is consumed when the rated operation is applied to the power circuit. (Rated power consumption = rated xcurrent consumption) Rated control capacity Means the reference value that is used to determine the performance of the switching part of the load. This value is represented by the combination of and current. Contact resistance Means the combined resistance that consists of the contact resistance between contacts, and the conductor resistance of pins and contact springs. Insulation resistance Means the resistance between a contact or a conductive pin like the pin to which the operation is applied, and a dead pin or a non-conductive metallic part like the time case, the base, or a retaining screw; or the resistance between contacts. Withstand Means the limit value that does not cause breakdown when high is applied for one minute to the same location as measured for insulation resistance. The detectable leak current is normally ma. In special cases, however, it may be ma or ma. Withstand surge Means the limit value that shows the durability against momentary abnormal resulting from lightning or switching a conductive load. The surge waveform is represented by the standard impulsive waveform at ±(.x) µs or ±(x) µs.

11 General application guidelines General Information Timers Cautions for circuits. Protective circuit for timer contact In the circuit that switches an inductive load, a contact failure may occur at a contact point due to surge or inrush current resulting from that switching. Therefore, it is recommended that the following protective circuit be used to protect the contact point. CR circuit (r: resistor c: capacitor) Timer contact Timer contact Diode circuit Timer contact Varistor circuit Timer contact Circuit r c Inductive load r c Inductive load Diode Inductive load ZNR varistor Inductive load Application AC DC Features/Notes Device Selection. Type of Load and Inrush Current The type of load and its inrush current characteristics, together with the switching frequency are important factors which cause contact welding. Particularly for loads with inrush currents, measure the steady state current and inrush current and use a relay or magnet switch which provides an ample margin of safety. The table below shows the relationship between typical loads and their inrush currents. Type of load Resistive load Solenoid load Motor load Incandescent lamp load Mercury lamp load Sodium vapor lamp load Capacitive load Transformer load (see note.)

This circuit further delays the release Note: If used with AC, be sure time compared to the CR circuit. the impedance of the load is sufficiently ( to times the release time listed in smaller than that of the c and r. the catalog) As a guide in selecting r and c, Use a diode with a reverse breakdown c:. to mf per A contact current at least times the r:. to W per V contact circuit and a forward current Values vary depending on the properties of the load and variations in timer characteristics. at least as large as the load current.

Inrush current Steady state current to times the steady state current to times the steady state current to times the steady state current to times the steady state current to times the steady state current to times the steady state current to times the steady state current When you want large load and long life of the timer, do not control the load direct with a timer. When the timer is designed to use a relay or a magnet switch, you can acquire the longer life of the timer.. Connection of input The PMH and LTH series use power supply without a transformer (power and input terminals are not insulated). In connecting various kinds of input signals, therefore, use a power transformer in which the primary side is separated from the ungrounded secondary side as shown in Fig. A, for the power supply for a sensor and other input devices so that short-circuiting can be prevented. (Fig. A) Good example AC power supply AC power supply Insulation transformer Timer (Fig. B) Bad example AC power supply Insulation transformer Timer Timer (+) ( ) (+) ( ) Single coil transformer (+) ( ) ( ) ( ) ( ) Input device (e.g., sensor) Input device (e.g., sensor) Input device (e.g., sensor) Alternative current flow Do not use a single coil transformer (e.g., Sly-Duck). Otherwise, the internal circuit of the timer will be short-circuited as shown in Fig. B resulting in breakdown.. Long Continuous Current Flow Long continuous current flow through the timer (approx. one month or longer) cause generation of heat internally, which degrade the electronic parts. Use the timer in combination with a relay and avoid long continuous current flow through the timer. () When using contact output R T R R () When using non-contact output (Fig. A) R R (Fig. B) Using the rated characteristics of the varistor, this circuit prevents excessively high s from being applied across the contacts. This circuit also slightly delays the release time. RT. Leakage current ) For connecting and disconnecting operating to the timer, a circuit should be used, which will prevent the flow of leakage current. For example, a circuit for contact protection as shown in Fig A. will permit leakage current flow through R and C, causing erroneous operation of the timer. Instead, the circuit shown in Fig. B should be used. T Leak current R R C T RT R C T T Timer Timer

12 General Information Timers General application guidelines ) If the timer is directly switched with a non-contact element, leak current may flow into the timer and cause it to malfunction.. Power off time If the operation for the timer is turned after the limit time operation is completed or before the limit time is reached, the Power off time longer than the timer restoration time must be secured.. Suicide circuit If the timer is restored immediately after the specified time is reached, the circuit must be configured so that the restoration time of the timer can be secured sufficiently. If the power circuit for the timer is turned with the timer contact, a suicide circuit may be configured (Fig. A). In order to settle the problem with this potential suicide circuit, the circuit must be designed so that the timer is turned after the self-retention circuit is completely released (Fig. B). R T A T (Fig. A) R R T A T (Fig. B). Electrical life The electrical life varies depending on the load type, the switching phase, and the ambient atmosphere. In particular, R the following cases require careful attention: () If an AC load is switched in synchronized phases: Locking or welding is liable to occur due to contact transposition. Check this with the actual system. ()If a load is switched very frequently: If a load which generates arcs when a contact is switched is turned and very frequently, nitrogen and oxygen in air are combined due to arc energy and then HNO is produced. This may corrode metallic materials. The effective countermeasures include:. Using an arc-extinguishing circuit;. Decreasing the switching frequency;. Decreasing the humidity in the ambient atmosphere. Cautions for use (common for all models). Pin connections Correctly connect the pins while seeing the terminal layout/wiring diagram. In particular, the DC type, which has polarities, does not operate with the polarities connected reverse. Any incorrect connection can cause abnormal heating or ignition.. Connection to operation power supply ) Supply must be applied at a time through a switch, a relay, and other parts. If the is applied gradually, the specified time may be reached regardless of its value or the power supply may not be reset. ) The operation for the DC type must be at the specified ripple percentage or less. The average must fall within the allowable operation range. Rectification type Ripple percentage Single-phase, full-wave Approx. % Three-phase, full-wave Approx. % Three-phase, half-wave Approx. % Note: Refer to the ripple percentage of each timer. ) Make sure that no induced and residual are applied between the power pins on the timer after the power switch is turned. (If the power line is wired in parallel with the high- and motor lines, induced may be produced between the power pins.). Control output ) The load for the control output must be used within the load capacity specified in the rated control capacity. If it is used exceeding the rated value, the life is greatly shortened. ) The following connection might result in short circuit between the heteropolar contacts in the timer. Bad example L L Good example L L. Installing the timer ) To install the timer, use the dedicated pin bracket or socket (cap). Avoid connecting the pins on the timer by directly soldering them. ) In order to maintain the characteristics, do not remove the timer cover (case).. Superimposed surge of power supply For the superimposed surge of power supply, the standard waveform (±.xµs or ±xµs) is taken as the standard value for surge-proof. (The positive and negative s are applied each three or five times between the power pins.) For the standard values for the PMH, LTH and SDX type timers, see the respective items in Cautions for use. Single-pole, full-wave for surge waveform [±(.x) µs] Crest value (%) Crest value. Time ( s) Single-pole, full-wave for surge waveform [±(x) µs] Crest value (%) Crest value Time ( s) PMH [±(x) µs] Voltage type Surge AC type (Except for V AC),V V DC, V DC, V AC V V DC,V to V DC,V If external surge occurs exceeding the specified value, the internal circuit may break down. In this case, use a surge absorption element. The typical surge absorption elements include a varistor, a capacitor, and a diode. If a surge absorption element is used, use an oscilloscope to see whether or not the foreign surge exceeding the specified value appears.. Changing the set time Do not change the set time when the limit time operation is in progress. However, this is possible only with the motor-driven type timer if the set time is shorter than the remaining time. For changing the set time on the digital timer (LTH series), see the relevant item in Cautions for use.

13 General Information Timers. environment ) Use the timer within the ambient temperature range from C to + C + F to + F (+ C + F for the LTH series) and at ambient humidity of % RH maximum. ) Avoid using the timer in a location where inflammable or corrosive gas is generated, the timer is exposed to much dust and other foreign matter water or oil is splashed on the timer or vibrations or shocks are given to the timer. ) The timer cover (case), the knobs, and the dials are made of polycarbonated resin. Therefore, prevent the timer from being exposed to organic solvents such as methyl alcohol, benzine, and thinner, strong acid substances such as caustic soda, and ammonia and avoid using the timer in atmosphere containing any of those substances. ) If the timer is used where noises are emitted frequently, separate the input signal elements (such as a sensor), the wiring for the input signal line, and the timer as far as possible from the noise source and the high power line containing noises.. Checking the actual load In order to increase the reliability in the actual use, check the quality of the timer in the actual usage.. Others ) If the timer is used exceeding the ratings (operation and control capacity), the contact life, or any other specified limit, abnormal heat, smoke, or ignition may occur. ) If any malfunction of the timer is likely to affect human life and properties, give allowance to the rated values and performance values. In addition, take appropriate safety measures such as a duplex circuit from the viewpoint of product liabilities.

Checking the operation mode When the UP or DOWN key at the second digit is pressed with the SET/LOCK switch pressed, the operational mode can be checked. The display returns to the normal condition after indicating the operational mode for about two seconds. (While the display indicates the operational mode for about two seconds, the other indicators continue to operate normally.) Setting the lock When the UP or DOWN key at the fourth digit is pressed with the SET/LOCK switch pressed, all keys on the unit are locked. The timer does not accept any of UP, DOWN and RESET keys. To release the lock setting, press the UP or DOWN key at the fourth digit again with the set/lock switch pressed. * Operational mode, adding and subtracting and minimum input signal range cannot be set at T and T, respectively. Changing over the T /T setting display The T/T setting display is changed over by pressing the SET/LOCK switch. (This operation gives no effect on the other operations. The set time and elapsed time (residual time) at T are linked with those at T.) Changing the set time ) It is possible to change the set time with the UP and DOWN keys even during time delay with the timer. However, be aware of the following points. () If the set time is changed to less than the elapsed time with the time delay set to the addition direction, time delay will continue until the elapsed time reaches full scale, returns to zero, and then reaches the new set time. If the set time is changed to a time above the elapsed time, the time delay will continue until the elapsed time reaches the new set time.

When using the unit by starting it with the power on, shortcircuit the start terminal (-pin: to, -pin: to and screw terminal: to ). The integrating input mode is operated by the integrated time of the start input. In other word, the timer operates only when the start input is performed. When the elapsed value is cleared by the reset input, the output is reset. When using the unit by starting it with the power on, shortcircuit the start terminal (-pin: to, -pin: to and screw terminal: to ). Each signal input such as start, reset, stop and lock inputs is applied by short-circuiting its input terminal and common terminal (-pin type: terminal, -pin type: terminal and screw terminal: terminal ) respectively. The -pin type does not have a stop input or lock input.

25 LTH series cautions for use. Terminal wiring ) When wiring the terminals, refer to the terminal layout and wiring diagrams and be sure to perform the wiring properly without errors. ) When using the instrument with an flush mounting, the screw-down terminal type is recommended. For the pin type, use either the rear terminal block (AT) or the P cap (AD-RC) for the -pin type, and the rear terminal block (AT) or the P cap (AT- DP) for the -pin type. Avoid soldering directly to the round pins on the unit. When using the instrument with a front panel installation, use the DIN rail terminal block (AT-DFK) for the -pin type and the DIN rail terminal block (AT- DFK) for the -pin type. ) After turning the unit off, make sure that any resulting induced or residual is not applied to power supply terminals through (-pin type) through (-pin type) or and (screw terminal type). (If the power supply wire is wired parallel to the high wire or power wire, an induced may be generated between the power supply terminals.) ) Have the power supply pass through a switch or relay so that it is applied at one time. If the power supply is applied gradually, the counting may malfunction regardless of the settings, the power supply reset may not function, or other such unpredictable occurrence may result.. Input connections The power circuit has no transformer (power and input terminals are not insulated). When an input signal is fed to two or more timers at once, do not arrange the power circuit in an independent way. If the timer is powered on and off independently as shown in Fig. A, the timer s internal circuitry may get damaged.be careful never to allow such circuitry. (Figs. A, B and C show the circuitry for the -pin type.) (Fig. A) Input contact point or transistor Input terminal Input terminal Power supply If independent power circuitry must be used, keep the input contacts or transistors separate from each other, as shown in Fig. B. (Fig. B) Input contact point or transistor Input contact point or transistor When power circuitry is not independent, one input signal can be fed to two or more counters at once, as shown in Fig. C. (Fig. C) Input contact point or transistor. Input and output ) Signal input type () Contact point input Use highly reliable metal plated contacts. Since the contact point s bounce time leads directly to error in the timer operations, use contacts with as short a bounce time as possible. Also, select a minimum input signal width of ms. -pin type input input type Input terminal Input terminal Stop input Lock input -pin type Input terminal Input terminal Power supply Power supply () Non-contact point input Connect with an open collector. Use transistors whose characteristics satisfy the criteria given below. VCEO = V min. IC = ma min. ICBO = µa max. Also, use transistors with a residual of less than V when the transistor is on. -pin type -pin type input to V DC Q input type type Stop input Lock input -pin type * The short-circuit impedance should be less than k. [When the impedance is, the current coming from the start input and stop input terminals is approximately ma, and from the reset input and lock input terminals is approximately. ma.] Also, the open-circuit impedance should be more than k. * As shown in the diagram below, from a non-contact point circuit (proximity switches, photoelectric switches, etc.) with a power supply of between and V, the signal can be input without using an open collector transistor. In the case of the diagram below, when the non-contact point transistor Q switches from off to on (when the signal goes from high to low), the signal is input. input -pin type (The above example is for reset input) ) The input mode and output mode change depending on the DIP switch settings. Therefore, before making any connections, be sure to confirm the operation mode and operation conditions currently set. ) The LTH series use power supply without a transformer (power and input terminals are not insulated). In connecting various kinds of input signals, therefore, use a power transformer in which the primary side is separated from the ungrounded secondary side as shown in Fig. A, for the power supply for a sensor and other input devices so that shortcircuiting can be prevented. Digital Timers

26 LTH series cautions for use Digital Timers Once the wiring to be used is completely installed and prior to installing this timer, confirm that there is complete insulation between the wires connected to the power terminals ( each) and the wires connected to each input terminal. If the power and input lines are not insulated, a short-circuit may occur inside the timer and result in internal damage. In addition, when moving your equipment to a new installation location, confirm that there is no difference in environmental conditions as compared to the previous location.

Never con- nect other terminals or s higher than V DC, because it may destroy the internal circuitry. ) Transistor output () Since the transistor output is insulated from the internal circuitry by a photocoupler, it can be used as an NPN As NPN output AC power supply Insulation transformer Timer Timer LTH timer (+) ( ) Single coil transformer (+) ( ) ( ) ( ) { O I Load Load s power supply Input device (e.g., sensor) Input device (e.g., sensor) Alternative current flow () Use the diode connected to the output transistor s collector for absorbing the reverse from induced loads. ) When wiring, use shielded wires or metallic wire tubes, and keep the wire lengths as short as possible. ) For the load of the controlled output, make sure that it is lower than the rated control capacity.. Operation of LTH digital timer ) Turning on and off the power supply while operating in A* (Power on delay ) or G (Totalizing On delay) will result in a timer error to be generated due to the characteristics of the internal circuitry. Therefore, use the start input or stop input. * Not related to the start input. ) When controlling the timer by turning on the power supply, use only A (Power on delay ) or A (Power on delay ). Use of other modes in this situation will result in timer errors. When using the other modes, control the timer with the start input or stop input.. Operation mode and time range setting The operation mode and time range can be set with the DIP switches on the side of the timer. Make the DIP switch settings before installing the timer on the panel. The operation mode of LTH-W series can be set with the keys and switches on the front of the timer.

Be sure to use surge absorbing element to prevent this from happening. ) Regarding external noise, the values below are considered the noise-resistant s. If s rise above these values, malfunctions or damage to the internal circuitry may result, so take the necessary precautions. Noise wave form (noise simulator) Rise time: ns

For example, when performing contact protection, if set up like that of fig. A, leaking current will C R C T T pass through C and R, enter the unit, and cause incorrect operation. The fig. B shows the correct setup. R T R Relay ) Long periods of continuous operation in the time-up completed condition (one month or more) will result in the weakening of the internal electrical components from the generated heat and, therefore, should be avoided. If you do plan to use the unit for such continuous operation, use in conjunction with a relay as shown in the circuit in the diagram below.. Acquisition of CE marking Please abide by the conditions below when using in applications that comply with EN-. ) Over category III, pollution level R T Timer R Receive output from contact at relay R ) This timer employs a power supply without a transformer, so the power and input signal terminals are not insulated. () When a sensor is connected to the input circuit, install double insulation on the sensor side. () In the case of contact input, use dualinsulated relays, etc. ) The load connected to the output contact should have basic insulation. This timer is protected with basic insulation and can be double-insulated to meet EN/IEC requirements by using basic insulation on the load. ) Please use a power supply that is protected by an overcurrent protection device which complies with the EN/IEC standard (example: V A fuse, etc.). ) You must use a terminal socket or socket for the installation. Do not touch the terminals or other parts of the timer when it is powered. When installing or un-installing, make sure that no is being applied to any of the terminals. ) Do not use this timer as a safety circuit. For example when using a timer in a heater circuit, etc., provide a protection circuit on the machine side. Digital Timers.

37 Precautions during usage. periods After unscheduled operations have been completed, or if the timer operation power supply has been turned off at any time during operation, a reset period of at least. seconds should be allowed before resuming operation.. External surge protection External surge protection may be required if the following values are exceeded. Otherwise, the internal circuit will be damaged. The typical surge absorption elements include a varistor, a capacitor, and a diode. If a surge absorption element is used, use an oscilloscope to see whether or not the foreign surge exceeding the specified value appears. Single-pole, full-wave for surge waveform [±(. ) µs] Crest value (%) Crest value ) If terminals are to be soldered directly, please hand solder with a to W solder iron with a tip temperature of C for no more than seconds. Automatic soldering should be avoided. ) A flux-tight construction is not used with this timer, so be careful that flux or cleaning fluid does not get inside the case. ) To assure that characteristics are maintained, do not remove the case.. Long Continuous Current Flow Long continuous current flow through the timer cause generation of heat internally, which degrade the electronic parts. Use the timer in combination with a relay and avoid long continuous current flow through the timer. (Refer to the circuit diagram below when using a safety circuit for continuous operation.) R R T T R ) Do not use this timer as a safety circuit. For example when using a timer in a heater circuit, etc., provide a protection circuit on the machine side.. Others ) When setting the time, the dial should be kept within the range indicated on the dial face. The marking on the dial indicates the minimum time during which the control time can be varied (it does not indicate seconds). ) Do not rotate the knob past the stopper. ) Turn off the power before changing the DIP switch settings. Changing the DIP switch with the power on can cause breakdown. ) When connecting the operating power supply, make sure that no leakage current enters the timer. For example, when performing contact protection, if set up like that of fig. A, leaking current will pass through C and R, enter the timer, and cause incorrect operation. The fig. B shows the correct setup. Analog Timers. Time (µs) Operation Surge to V AC, to V AC,V V DC, V DC,V Since the main body cover and knob are made of polycarbonate resin, prevent contact with organic solvents such as methyl alcohol, benzine and thinner, or strong alkali materials such as ammonia and caustic soda.. Terminal wiring Make sure that terminals are wired carefully and correctly, referring to the terminal layout and wiring diagrams. Particularly, since the DC type has polarity, do not operate it with reverse polarity.. Assembly ) When installing, use a terminal socket or socket intended for the HC/HJ relay. For adjacent installations, be sure to first verify the installation conditions of the terminal sockets or sockets you will be using. ) Use the separately-sold dedicated socket leaf holding clip to secure terminal sockets and sockets to the timer unit. The conditions of use for dedicated socket leaf holding clip will differ depending on the terminal socket or socket you will be using. Therefore, please test under actual conditions before putting into operation.. Phase synchronization using AC load If the turning on of the timer output relay is synchronized to the AC power supply phase, there may be times when the service life is shortened because of electrical factors, or when a locking phenomenon (defective relay return) occurs because of contact point welding or a shift in the contact relay. Check the operation using the actual timer.. Acquisition of CE marking Please abide by the conditions below when using in applications that comply with EN-. ) Over category II, pollution level ( Form C type) Over category II, pollution level ( Form C type) ) The load connected to the output contact should have basic insulation. This timer is protected with basic insulation and can be double-insulated to meet EN/IEC requirements by using basic insulation on the load. ) Please use a power supply that is protected by an overcurrent protection device which complies with the EN/IEC standard (example: V A fuse, etc.). ) You must use a terminal socket or socket for the installation. Do not touch the terminals or other parts of the timer when it is powered. When installing or uninstalling, make sure that no is being applied to any of the terminals. power supply power supply When a contact switch having an operation indicating lamp (lamp equipped limit switch, etc.) is used to apply power to the timer, a resistor having a value equal to or greater than the value below shall be connected in series with the lamp. to V AC operating type: Min. kω to V AC operating type: Min. kω Limit switch Resistor Neon lamp Leakage current R T (Fig. A) (Fig. B) C R C T WRG CORRECT T Example of limit switches with lamp.

Connect terminals b-g (screw terminal -) for reset signal input. Connect terminals b-e (screw terminal -) for stop signal input. Be sure not to connect with other terminals and apply excessive. The internal circuit will be damaged. ) The input wiring other than the power supply circuit should avoid these conditions, high- wiring and parallel wiring with power wire. Wire in short with using the shielding wire or metal wiring tube. ) For start, reset and stop input, use gold-plated contact with high reliability. Since contact bouncing causes errors in the start, use an input contact less bounce time. ) Keep the minimum signal input time over. s.. Input signal conditions input input Stop input (PMH-A type) ) Connection of contact input (Pin type example Use gold-plated contacts with highreliability. The bounce time at the contacts causes errors in the timer operation time. Accordingly, use start input contact whose bounce time is short. The resistance when shorted should be less than kω, and when open resistance should be more than kω. For the screw terminal type, connect the terminal to the each input signal. input input Stop input ) Connection of non-contact input (Pin type example) (open-collector) Apply the open-collector connection. The characteristics of the transistor used must be VCEO=V or more, IC=mA or more, and ICBO=µA or less. Additionally, the input impedance must be kω or less, and the residual must be.v or less.

[Example of start input] Even if the open collector is not used, input is also possible from the non-contact circuit of to V DC. In this case, the start input is turned on when the signal is turned from H to L. The residual must be.v or less when Q is on. On the AC type, an insulated transformer is required as the power supply for the photoelectric sensor, etc. (power supply for the input devices). Note: Keep the minimum input signal time of each signal to.s or more.. Checking the contacts before use (PMH-F only) When the power time is less than the minimum power application time, the contacts may remain in an state, so the state of the contacts should be checked before use. When the contacts are in an state, activating them once will return them to their normal state (the state after time-out). (Be aware that relay characteristics may result in the contacts being in that same state if exposed to excessive vibration and impact during transport.). Time setting To set the time, turn the set dial to a desired time within the range. Instantaneous output will be on when the dial is set to. When the instantaneous output is used, the dial should be set under range. (Instantaneous output area) Note) When power supply is on, the time range, setting time and operation mode cannot be changed. Turn off the power supply or a reset signal is applied to set the new operation mode. If the position is not stable, the timer might mis-operate. Analog Timers

64 Precautions in using the counter Cautions for circuits. Protective circuit for counter contact In the circuit that switches an inductive load, a contact failure may occur at a contact point due to surge or inrush current resulting from that switching. Therefore, it is recommended that the following protective circuit be used to protect the contact point. CR circuit (r: resistor c: capacitor) Diode circuit Varistor circuit Counter contact Counter contacts Counter contacts Counter contacts Circuit r c Inductive load r c Inductive load Diode Inductive load ZNRvaristor Inductive load Application AC DC Features/Others Device Selection (see note.)

The diode connected in parallel Effective when connected to both contacts if the power supply is causes the energy stored in the coil or V and the across the load is to V. to flow to the coil in the form of current and dissipates it as joule heat If the load is a timer, leakage current at the resistance component of the flows through the CR circuit causing inductive load. faulty operation. This circuit further delays the release Note: If used with AC, be sure time compared to the CR circuit. the impedance of the load is sufficiently ( to times the release time listed in smaller than that of the CR circuit. the catalog) As a guide in selecting r and c, Use a diode with a reverse breakdown c:. to µf per A contact current at least times the r:. to W per V contact circuit and a forward current Values vary depending on the properties of the load and variations in counter characteristics. at least as large as the load current.

Test to confirm. circuit s reverse breakdown Use a capacitor with a breakdown of to V. Use AC type capacitors of about to times the (non-polarized) for AC circuits. power supply.. Type of load and inrush current The type of load and its inrush current characteristics, together with the switching frequency, are important factors which cause contact welding. Particularly for loads with inrush currents, measure the steady state current and inrush current and use a relay or magnet switch which provides an ample margin of safety. The table below shows the relationship between typical loads and their inrush currents. Type of load Inrush current Resistive load Steady state current Solenoid load to times the steady state current Motor load to times the steady state current Incandescent lamp load to times the steady state current Mercury lamp load to times the steady state current Sodium vapor lamp load to times the steady state current Capacitive load to times the steady state current Transformer load to times the steady state current When you want large load and long life of the counter, do not control the load direct with a counter. When the counter is designed to use a relay or a magnet switch, you can acquire the longer life of the counter.. Connection of input (Except for LCH-S/AC type) The LCH series use power supply without a transformer (power and input terminals are not insulated). In connecting various kinds of input signals, therefore, use a power transformer in which the primary side is separated from the ungrounded secondary side as shown in Fig. A, for the power supply for a sensor and other input devices so that shortcircuiting can be prevented. Do not use a single coil transformer (e.g., Sly-Duck). Otherwise, the internal circuit of the counter will be short-circuited as shown in Fig. B resulting in breakdown. (Fig. A) Good (Fig. B) No good AC power supply AC power supply Insurating transformer Counter Counter Counter (+) ( ) Insurating transformer (+) ( ) Single coil transformer (+) ( ) ( ) ( ) Input equipment (sensor, etc.) Input equipment (sensor, etc.) Input equipment (sensor, etc.) ( ) AC power routing Using the rated characteristics of the varistor, this circuit prevents excessively high s from being applied across the contacts. This circuit also slightly delays the release time.. Long continuous current flow Avoid keeping the counter on for a long period of time (over one month). Otherwise heat is generated and accumulated inside the counter, which may deteriorate its electronic parts. If the counter must be kept on for a long period of time, a relay is added. See the circuit diagram below. R C R Relay R C Counter R Receive output from contact at relay R. Leakage current ) For connecting operating to the counter, a circuit should be used, which will prevent the flow of leakage current. For example, a circuit for contact protection as shown in Fig A. will permit leakage current flow through R and C, causing erroneous operation of the counter. Instead, the circuit shown in Fig. B should be used. (Fig. A) Leakage current R C C Counter (Fig. B) ) If the counter is directly switched with a non-contact element, leak current may flow into the counter and cause it to malfunction.

65 PRECAUTIS IN USING THE COUNTER Counters Cautions for use (common for all models). Terminal connections Correctly connect the pins while seeing the terminal layout/wiring diagram. In particular, the DC type, which has polarities, does not operate with the polarities connected reverse. Any incorrect connection can cause abnormal heating or ignition.. Connection to operating )Apply the entire supply through a switch, relay or other contact. ) The operating for the DC type must be at the specified ripple percentage or less. The average must fall within the allowable operating range. Rectification type Ripple percentage Single-phase, full-wave Approx. % Three-phase, full-wave Approx. % Three-phase, half-wave Approx. % ) Make sure that no induced and residual are applied between the power terminals on the counter after the power switch is turned. (If the power line is wired in parallel with the high- and motor lines, induced may be produced between the power pins.). Control output ) Keep the load capacity below the counter s rated control capacity. If used above the rating, the counter s service life may shorten. With the transistor output type counters, transistors may be damaged.. Installing the counter ) To install the counter, use the dedicated pin bracket or socket (cap). Avoid connecting the pins on the counter by directly soldering them. ) In order to maintain the characteristics, do not remove the counter cover (case).. Superimposed surge of power supply For the superimposed surge of power supply, the standard waveform (±.xµs or ±xµs) is taken as the standard value for surge-proof. (The positive and negative s are applied each three or five times between the power pins.) For the standard values for the LCH type counters, see the respective items in Cautions for use. Single-pole, full-wave for surge waveform [±(.x) µs] Surge (%) Peak value. Time ( s) If external surge occurs exceeding the specified value, the internal circuit may break down. In this case, use a surge absorption element. The typical surge absorption elements include a varistor, a capacitor, and a diode. If a surge absorption element is used, use an oscilloscope to see whether or not the foreign surge exceeding the specified value appears.. Signal input The counter s signal input comes in two ways. One is by opening and closing the input terminal. The other is by applying a specified H-level or L-level to the input terminal. For an input sensor s residual, input impedance, input level and other signal input conditions, see the ratings for each type of product.. environment ) For the ambient operating temperature and humidity, see the ratings for each type of product. ) Avoid using the counter in a location where inflammable or corrosive gas is generated, the counter is exposed to much dust and other foreign matter; water or oil is splashed on the counter; or vibrations or shocks are given to the counter. ) The counter cover (case), the knobs, and the dials are made of polycarbonated resin. Therefore, prevent the counter from being exposed to organic solvents such as methyl alcohol, benzine, and thinner, strong acid substances such as caustic soda, and ammonia and avoid using the counter in atmosphere containing any of those substances. ) If the counter is used where noises are emitted frequently, separate the input signal elements (such as a sensor), the wiring for the input signal line, and the counter as far as possible from the noise source and the high power line containing noises. Counter Input line As remote as possible Power line, etc. Sensor, etc.. Checking the actual load In order to increase the reliability in the actual use, check the quality of the counter in the actual usage.. Others ) If the counter is used exceeding the ratings (operating and control capacity), the contact life, or any other specified limit, abnormal heat, smoke, or ignition may occur. ) The LCH series counter, incorporates a lithium battery. Never disassemble the lithium battery or throw it into fire because this may affect humans and facilities. The lithium battery must be disposed of as an incombustible like other used batteries. ) If any malfunction of the counter is likely to affect human life and properties, give allowance to the rated values and performance values. In addition, take appropriate safety measures such as a duplex circuit from the viewpoint of product liabilities.

73 LCH Counters Cautions for use. Non- input type For both panel mounting and PC board mounting types ) Never apply to the non- input type. This will damage the internal elements. Also, since there is a possibility of erroneous operation, do not connect in parallel the inputs of a non- input type and another counter from a single input signal. ) Since the current flow is very small from the count input and reset input terminals ( and on the panel mounting type and terminals e to t and S to F on the PC board mounting type) please use relays and switches with high contact reliability. ) When inputting with an open collector of a transistor, use a transistor for small signals in which ICBO is µa or less and always input with no. ) When wiring, try to keep all the input lines to the count and reset inputs as short as possible and avoid running them together with high and power transmission lines or in a power conduit. Also, malfunctions might occur if the floating capacitance of these wires exceeds pf ( m. ft. for parallel wires of mm ). When using khz mode, use with a wiring floating capacitance of pf ( m. ft. for parallel wires of mm ). In particular, when using shielded wiring, be careful of the capacitance between wires. PC board mounting type ) For external power supply use manganese dioxide or lithium batteries (CR type: V). ) Always reset after external power is applied and confirm that the display reads. ) Make the wiring from the battery to the counter unit as short as absolutely possible. Also, be careful of polarity. ) Calculate battery life with the following formula. t = A/I t: battery life [h] I: LCH current consumption [ma] A: battery capacity until minimum operation is reached [mah] ) Hand solder to the lead terminal. Do not dip solder. With the tip of the soldering iron at C F perform soldering within seconds (for to W soldering iron).. Voltage input type ) Be aware that applying more than V DC to count input terminals and, and reset input terminals and will cause damage to the internal elements. ) For external resetting use H level (application of. to V DC) between reset terminals and of the rear terminals. In this case, connect + to terminal and to terminal. This is the valid polarity; therefore, the counter will not work if reversed. ) When wiring, try to keep all the input lines to the count and reset inputs as short as possible and avoid running them together with high and power transmission lines or in a power conduit. Also, malfunctions might occur if the floating capacitance of these wires exceeds pf ( m. ft. for parallel wires of mm ).. Free input type ) Use count input terminals and for free input and reset terminals and for non- input. ) Be aware that the application of that exceeds the range of the H level to the count input terminal, and the application of to the reset input terminal, can cause damage to the internal elements. ) Since the current flow is very small from reset input terminal, please use relays and switches with high contact reliability. ) When inputting a reset with an open collector of a transistor, use a transistor for small signals in which ICBO is µa or less and always input with no. ) To reset externally, short reset input terminals and on the rear. ) Input uses a high impedance circuit; therefore, erroneous operation may occur if the influence of induction is present. If you plan to use wiring for the input signal that is m or longer (wire capacitance pf/m at normal temperature), we recommend the use of a CR filter or the connection of a bleeder resistor..

80 Precautions in using the LCH series Cautions for use. Input and output connection ) Input connection () Contact input Use highly reliable metal plated contacts. Since the contact s bounce time leads directly to error in the count value, use contacts with as short a bounce time as possible. In general, select input to have a maximum counting speed of Hz. Count input input () Non-contact input (Transistor input) Connect with an open collector. Use transistors whose characteristics satisfy the criteria given below. VCEO = Min. V IC = Min. ma ICBO = Max. µa Also, use transistors with a residual of less than V when the transistor is on. * The short-circuit impedance should be less than kω. (When the impedance is Ω, the current coming from the count input terminal is approximately ma and from the reset input terminal is approximately. ma.) Also, the open-circuit impedance should be more than kω. Count input input () Input wiring When wiring, use shielded wires or metallic wire tubes, and keep the wire lengths as short as possible. ) Output connection Since the transistor output of counter is insulated from the internal circuitry by a photo-coupler, it can be used as an NPN output or PNP (equal value) output.

To unlock the keys,hold down the SET/LOCK key and press the UP key for the sixth digit again. * The input mode, maximum counting speed and minimum reset signal width cannot be preset independently for Setting and Setting. Selecting the Setting or Setting display Press the SET/LOCK key and the display changes between Setting and Setting. (This operation does not affect overall operation.) Changing the setting. While the counter is working, the UP key can be used to change the setting. Keep the following points in mind, however. ) Suppose that a preset count-up value is smaller than the displayed count value. The counter counts up to the full scale mark (), goes back to, and counts up again to the preset number. When the preset count-up value is larger than the displayed count value, the counter counts up to the preset value. ) Suppose that the counter is preset to count down. Whether a preset count-down value is smaller or larger than the count value, the counter counts down to.. When the preset value is, the counter does not start in the count-up mode. It starts counting up when the count value comes to again. ) Up-count input The counter counts up to the full scale mark (), goes back to and starts counting up again. ) Down-count input The counter counts down to the full scale mark ( ) and the display reads. The count value does not become and so the counter does not count up. ) Direction input, individual input, and phase input The preset value is counted up or down to any number other than once.

107 Precautions in using the LCH series Counters Precautions during usage. Terminal wiring ) When wiring the terminals, refer to the terminal layout and wiring diagrams and be sure to perform the wiring properly without errors. ) When using the instrument with an flush mounting, the screw-down terminal type is recommended. For the pin type, use either the rear terminal block (AT) or the P cap (AD-RC) for the -pin type, and the rear terminal block (AT) or the P cap (AT- DP) for the -pin type. Avoid soldering directly to the round pins on the unit. When using the instrument with a front panel installation, use the DIN rail terminal block (AT-DFK) for the -pin type and the DIN rail terminal block (AT- DFK) for the -pin type. ) After turning the counter off, make sure that any resulting induced or residual is not applied to power supply terminals through (-pin type), through (-pin type) or and (screw terminal type). (If the power supply wire is wired parallel to the high wire or power wire, an induced may be generated between the power supply terminals.) ) Have the power supply pass through a switch or relay so that it is applied at one time. If the power supply is applied gradually, the counting may malfunction regardless of the settings, the power supply reset may not function, or other such unpredictable occurrence may result.. Input connections (except LCH-S/ AC type) The power circuit has no transformer without a transformer (power and input terminals are not insulated). When an input signal is fed to two or more counters at once, do not arrange the power circuit in an independent way. If the counter is powered on and off independently as shown in Fig. A, the counter s internal circuitry may get damaged. Be careful never to allow such circuitry. (Figs. A, B and C show the circuitry for the -pin type.) (Fig. A) Input contact or transistor Input terminal Input terminal Power supply If independent power circuitry must be used, keep the input contacts or transistors separate from each other, as shown in Fig. B. (Fig. B) Input contact or transistor Input contact or transistor When power circuitry is not independent, one input signal can be fed to two or more counters at once, as shown in Fig. C. (Fig. C) Input contact or transistor Input terminal Input terminal Input terminal Input terminal. Input and output ) Signal input type () Contact point input Use highly reliable metal plated contacts. Since the contact point s bounce time leads directly to error in the count value, use contacts with as short a bounce time as possible. In general, select Input and Input to have a maximum counting speed of Hz and to be reset with a minimum input signal width of ms. input Input Input Lock input Power supply Power supply -pin type -pin type type Note: The LCH-W does not have the lock input,. () Non-contact point input Connect with an open collector. Use transistors whose characteristics satisfy the criteria given below. VCEO = V min. IC = ma min. ICBO = µa max. Also, use transistors with a residual of less than V when the transistor is on. input Input Input Lock input -pin type -pin type type Note: The LCH-W does not have the lock input,. * The short-circuit impedance should be less than k. [When the impedance is, the current coming from the input and input terminals is approximately ma, and from the reset input and lock input terminals is approximately. ma.] Also, the open-circuit impedance should be more than k. * As shown in the diagram below, from a non-contact point circuit (proximity switches, photoelectric switches, etc.) with a power supply of between and V, the signal can be input without using an open collector transistor. In the case of the diagram below, when the non-contact point transistor Q switches from off to on (when the signal goes from high to low), the signal is input. to V DC Q input -pin type -pin type type (The above example is for reset input) ) The input mode and output mode change depending on the DIP switch settings. Therefore, before making any connections, be sure to confirm the operation mode and operation conditions currently set.

108 ) The LCH series use power supply without a transformer (power and input terminals are not insulated). In connecting various kinds of input signals, therefore, use a power transformer in which the primary side is separated from the ungrounded secondary side as shown in Fig. A, for the power supply for a sensor and other input devices so that short-circuiting can be prevented. Once the wiring to be used is completely installed and prior to installing this counter, confirm that there is complete insulation between the wires connected to the power terminals ( each) and the wires connected to each input terminal. If the power and input lines are not insulated, a short-circuit may occur inside the counter and result in internal damage. In addition, when moving your equipment to a new installation location, confirm that there is no difference in environmental conditions as compared to the previous location. (except LCH-S/AC type) (Fig. A) Good example AC power supply AC power supply Insulation transformer Counter (Fig. B) Bad example AC power supply Counter Counter ) The input signal is applied by the shorting of each input terminal with the common terminal (terminal Q for -pin type, terminal E for -pin type and terminal for screw terminal types). Never connect other terminals or s higher than V DC, because it may destroy the internal circuitry. ) Transistor output () Since the transistor output is insulated from the internal circuitry by a photocoupler, it can be used as an NPN output or PNP (equal value) output. (The above example is -pin type) (+) ( ) Insulation transformer (+) ( ) Single coil transformer (+) ( ) ( ) ( ) ( ) Input device (e.g., sensor) Input device (e.g., sensor) Input device (e.g., sensor) Alternative current flow As NPN output As PNP output Diode rating: IF (forward current): A VR (reverse ): V LCH counter { O I LCH counter Load Load s power supply LCH counter { O I Load Load s power supply Note: With the LCH -pin type and the LCH-W, there is no diode between points I and O. () Use the diode connected to the output transistor s collector for absorbing the reverse from induced loads. (LCH only) Load s power supply Inductive load ) When wiring, use shielded wires or metallic wire tubes, and keep the wire lengths as short as possible.. Output mode setting The output mode can be set with the DIP switches on the side of the counter. Make the DIP switch settings before installing the counter on the panel.. Conditions of usage ) Avoid locations subject to flammable or corrosive gases, excessive dust, oil, vibrations, or excessive shocks. ) Since the cover of the unit is made of polycarbonate resin, avoid contact with or use in environments containing methyl alcohol, benzene, thinners, and other organic solvents; and ammonia, caustic sodas, and other alkaline substances. ) If power supply surges exceed the values given below, the internal circuits may become damaged. Be sure to use surge absorbing element to prevent this from happening. ) Regarding external noise, the values Surge (peak value) AC type,v DC type V AC type,v Surge (%) below are considered the noise-resista s. If s rise above these values, malfunctions or damage to the internal circuitry may result, so take the necessary precautions. Noise wave form (noise simulator) Noise Peak value. Time (µs) Power supply terminals DC type AC type V AC type Input termina,v,v V Rise time: ns Pulse width: µs, ns Polarity: ± Cycle: cycles/second ) When connecting the operation pow supply, make sure that no leakage current enters the counter. For example, when performing contact protection, if set up like that of diagram A, leaking cu rent will pass through C and R, enter th unit, and cause incorrect operation. Diagram B shows the correct setup. Operation power supply Operation power supply Leakage current R (Fig. A) (Fig. B) ) Long periods of continuous operation in the count-up completed condition (on month or more) will result in the weaken ing of the internal electrical components from the generated heat and, therefore should be avoided. If you do plan to use the unit for such continuous operation, use in conjunction with a relay as show in the circuit in the diagram below.

Compliance with the CE marking When using in applications to which EN- applies, abide by the following conditions. Over category II, pollution level (for sensor type model with power supply). Connections between the power supply and input/output have basic insulation. Use a device with basic insulation to connect to the I/O terminals. (for sensor type model without power supply) ) This counter employs a power supply without a transformer, so the power and input signal terminals are not insulated. () When a sensor is connected to the input circuit, install double insulation on the sensor side. () In the case of contact input, use dualinsulated relays, etc. The load connected to the output contact should have basic insulation. This counter is protected with basic insulation and can be double-insulated to meet EN/IEC requirements by using basic insulation on the load. Applied should be protected with an overcurrent protection device (example: V A fuse, etc.) that conforms to the EN/IEC standards. ) You must use a terminal block or socket for installing the pin-type counter. Do not touch the terminal section or other parts of the timer unit while an electric current is applied. Before installation or removal, confirm that there is no being applied to any of the terminals. ) Do not use this timer with a safety circuit. For example, when using a timer in a heater circuit, etc., provide a protection circuit on the machine side. Counters

110 Installing the DIN size counter (common) Installation methods. Surface mount ) For the counters of LCH series, use the pin type counter. ) Put the terminal socket on the board directly or put it on the DIN rail (Fig. ). ) Insert the counter into the terminal socket and fix it with clip (Fig. ) ) On DIN rail mounting, mount the counter on the DIN rail tightly to get the proper dimension (Fig. ). Terminal socket (Fig. ) (Fig. ) (Fig. ) DIN rail ) -pin type should be connected with terminal socket AT-DFK. -pin type should be connected with terminal socket AT-DFK. ) DIN rail (AT-DLA) is also available ( m).. Flush mount ) For the counters of LCH series, it is recommended to use the built-in screw terminal type for flush mount. (Mounting frame and rubber gasket are provided when counter is shipped.) ) How to mount the counter From the panel front, pass the counter through the square hole. Fit the mounting frame from the rear, and then push it in so that the clearance between the mounting frame and the panel surface is minimized. In addition, lock the mounting frame with a screw. Panel cover Rubber gasket ) Caution in mounting the counter ) If the LCH series are used as the waterproof types (IEC IP), tighten the reinforcing screws on the mounting frames so that the counters, the rubber gaskets, and the panel surfaces are tightly contacted with each other. (Tighten the two screws with uniform force and make sure that there is no rattling. If the screws are tightened too excessively, the mounting frame may come off.) ) If the counter is installed with the panel cover and the rubber gasket removed, the waterproofing characteristic is lost. ) Removal Loosen the screws on the mounting frame, spread the edge of frame and remove it. Pull the mounting frame backward while spreading out its hooks with your thumbs and index fingers. Mounting flame Screw PUSH ) Correctly connect the terminals while seeing the terminal layout and wiring diagram. ) If the pin type is used, the rear pinbracket (AT-RR) or the P cap (AD- RC) is necessary to connect the pins. For the -pin type, use the P cap (AT-DP) and avoid directly soldering the round pins on the counter. ) Panel cutout dimensions The standard panel ) Although the counters can be mounted adjacent to each other in this case, it is recommended to arrange the mounting holes as shown in the figure to facilitate attaching and detaching the mounting frame. cutout dimensions are shown in the left figure. (Panel thickness: to mm. to. inch) ) Adjacent mounting Although the counters can be mounted adjacent to each other, remember that the panel surface of LCH series counter will lose its water-resistant effect. (Panel thickness: to mm. to. inch) A = (xn.) +. + When lining up the counters horizontally, set the frames in such a position so the formed spring areas are at the top and bottom.

120 Cautions for use. Non- input type For both panel mounting and PC board mounting types ) Never apply to the non- input type. This will damage the internal elements. ) Since the current flow is very small from the start input and reset input terminals ( and on the panel mounting type and terminals e to t and S to F on the PC board mounting type) please use relays and switches with high contact reliability. When inputting with an open collector of a transistor, use a transistor for small signals in which ICBO is µa or less and always input with no. ) When wiring, try to keep all the input lines to the start and reset inputs as short as possible and avoid running them together with high and power transmission lines or in a power conduit. Also, malfunctions might occur if the floating capacitance of these wires exceeds pf ( m. ft. for parallel wires of mm ). In particular, when using shielded wiring, be careful of the capacitance between wires. PC board mounting type ) For external power supply use manganese dioxide or lithium batteries (CR type: V). ) Always reset after external power is applied and confirm that the display reads. ) Make the wiring from the battery to the hour meter unit as short as absolutely possible. Also, be careful of polarity. ) Calculate battery life with the following formula. t = A/I t: battery life [h] I: LHH current consumption [ma] A: battery capacity until minimum operation is reached [mah] ) Hand solder to the lead terminal. Do not dip solder. With the tip of the soldering iron at C F perform soldering within seconds (for to W soldering iron).. Voltage input type ) Be aware that applying more than V DC to start input terminals and, and reset input terminals and will cause damage to the internal elements. ) For external resetting use H level (application of. to V DC) between reset terminals and of the rear terminals. In this case, connect + to terminal and to terminal. This is the valid polarity; therefore, the hour meter will not work if reversed. ) When wiring, try to keep all the input lines to the start and reset inputs as short as possible and avoid running them together with high and power transmission lines or in a power conduit. Also, malfunctions might occur if the floating capacitance of these wires exceeds pf ( m. ft. for parallel wires of mm ).. Free input type ) Use start input terminals and for free input and reset terminals and for non- input. ) Be aware that the application of that exceeds the range of the H level to the start input terminal, and the application of to the reset input terminal, can cause damage to the internal elements. ) Since the current flow is very small from reset input terminal, please use relays and switches with high contact reliability. ) When inputting a reset with an open collector of a transistor, use a transistor for small signals in which ICBO is µa or less and always input with no. ) To reset externally, short reset input terminals and on the rear. ) Input uses a high impedance circuit; therefore, erroneous operation may occur if the influence of induction is present. If you plan to use wiring for the input signal that is m or longer (wire capacitance pf/m at normal temperature), we recommend the use of a CR filter or the connection of a bleeder resistor.. How to reset multiple panel mounting type counters all at once (input is the same for count) Non- input type D D D Tr or Notes). Use the following as a guide for choosing transistors used for input (Tr). Leakage current < µa. Use as small a diode (D) as possible in the forward so that the between terminals and during reset input meets the standard value (. V). ( At IF = µa, forward. and higher.) Voltage input type +V +V R Tr or Note) Make sure that H (reset ) level is at least. V..

148 x International standards International Standards IEC standard International Electrotechnical Commission By promoting international cooperation toward all problems and related issues regarding standardization in the electrical and electronic technology fields, the IEC, a non-governmental organization, was started in October,, for the purpose of realizing mutual understanding on an international level. To this end, the IEC standard was enacted for the purpose of promoting international standardization. Europe EN standard European Standards/Norme Europeennee (France)/Europaishe Norm (Germany) Abbreviation for European Standards. A unified standard enacted by CEN/CENELEC (European Standards Committee/European Electrical Standards Committee). EU and EFTA member nations employ the content of the EN standards into their own national standards and are obligated to abolish those national standards that do not agree with the EN standards. North America UL (Underwiters Laboratories Inc.) LISTING MARK Fig. RECOGNITI MARK Fig. Certification Fig. Component Acceptance Fig. Fig. Fig. This is a non-profit testing organization formed in by a coalition of U.S. fire insurance firms, which tests and approves industrial products (finished products). When electrical products are marketed in the U.S., UL approval is mandated in many states, by state law and city ordinances. In order to obtain UL approval, the principal parts contained in industrial products must also be ULapproved parts. UL approval is divided into two general types. One is called listing (Fig. ), and applies to industrial products (finished products). Under this type of approval, products must be approved unconditionally. The other type is called recognition (Fig. ), and is a conditional approval which applies to parts and materials. CSA (Canadian Standards Association) This was established in as a non-profit, nongovernmental organization aimed at promoting standards. It sets standards for industrial products, parts, and materials, and has the authority to judge electrical products to determine whether they conform to those standards. The CSA is the ultimate authority in the eyes of both the government and the people in terms of credibility and respect. Almost all states and provinces in Canada require CSA approval by law, in order to sell electrical products. As a result, electrical products exported from Japan to Canada are not approved under Canadian laws unless they have received CSA approval and display the CSA mark. Approval is called certification, and products and parts which have been approved are called certified equipment, and display the mark shown in Fig.. The mark shown in Fig. is called the Component Acceptance mark, and indicates conditional approval which is applicable to parts. The C-UL mark shown in Fig. (finished products) and Fig. (parts) indicates that the product has been tested and approved in UL laboratories, based on UL and CSA standards, through mutual approval activities. ENEC mark Germany The ENEC mark, approved by certifying authorities in Europe, is for electronic products. It can be displayed when a product is compliant with the European safety standard (EN standard). Device switches that display the ENEC mark can be freely distributed in the European Economic Area. VDE (Verband Deutscher Elektrotechniker) The VDE laboratory was established mainly by the German Electric Technology Alliance, which was formed in. It carries out safety experiments and passes approval for electrical devices and parts. Although VDE certification is not enforced under German law, punishment is severe should electrical shock or fire occur; therefore, it is, in fact, like an enforcement. TÜV (Technischer Überwachungs-Verein) TÜV is a civilian, non-profit, independent organization that has its roots in the German Boiler Surveillance Association, which was started in for the purpose of preventing boiler accidents. A major characteristic of TÜV is that it exists as a combination of independent organizations (TÜV Rheinland, TÜV Bayern, etc.) throughout Germany. TÜV carries out inspection on a wide variety of industrial devices and equipment, and has been entrusted to handle electrical products, as well, by the government. TÜV inspection and certification is based mainly on the VDE standard. TÜV certification can be obtained from any of the TÜVs throughout Germany and has the same effectiveness as obtaining VDE certification. Shipping Standards Lloyd s Register of Shipping Standards from the Lloyd s Register shipping association based in England. These standards are safety standards for environmental testing of the temperature and vibration tolerances of electrical components used for UMS (unmanned machine rooms in marine vessels) applications. These standards have become international standards for control equipment in all marine vessel applications. No particular action is taken to display the conformation to these standards on the products. Applications, Power Supplies International Standards
