5 PMS Precautions during usage. Avoid locations subject to flammable or corrosive gases, excessive dust, oil, vibrations, or excessive shocks.. Since the main-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.. Power supply superimposed surge protector Although a surge protector will withstand standard-waveform voltage with the values in the next table, anything above this will destroy the internal circuit. You should therefore use a surge absorber. V DC 00 to 0 V AC V DC 00 to 0 V AC 00 V,000 V Surge waveform [±(. 0) µs uni-polar full wave voltage]. In order to maintain the characteristics, do not remove the timer case.. When installing the panel, use the AA mounting frame (Sold separately).. If you change the operating voltage, be sure not to allow leak current into the timer.. Avoid leaving the unit powered continuously. eaving the unit powered up with output set to continuously for a long period of time (about month or more) will wear out the electronic components. If you will be keeping it powered continuously, combine with a relay to create the circuit shown below: R R R. he timer setting dial should only be turned within the range indicated on the dial face. urning it too far may break the stopper and cause damage to internal components. Acquisition of CE marking Please abide by the conditions below when using in applications that comply with EN-.. Overvoltage category III, pollution level. he load connected to the output contact should have basic insulation. his timer is protected with basic insulation and can be doubleinsulated 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: 0 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 voltage 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.

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 0.0 s.. Input signal conditions (PMH-A type) ) Connection of contact input (Pin type example Reset input Start input Stop input Use gold-plated contacts with high-reliability. he bounce time at the contacts causes errors in the timer operation time. Accordingly, use start input contact whose bounce time is short. he resistance when shorted should be less than kω, and when open resistance should be more than 00kΩ. For the screw terminal type, connect the terminal x to the each input signal. ) Connection of non-contact input (Pin type example) (open-collector) Reset input Start input Stop input Apply the open-collector connection. he characteristics of the transistor used must be VCEO=0V or more, IC=0mA or more, and ICBO=µA or less. Additionally, the input impedance must be kω or less, and the residual voltage must be 0.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 0V DC. In this case, the start input is turned on when the signal is turned from H to. he residual voltage must be 0.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 0.0s 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.). ime setting o 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 0. When the instantaneous output is used, the dial should be set under 0 range.

(ighten 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.) b If the timer is installed with the panel cover and the rubber gasket removed, the waterproofing characteristic is lost. ) Installation oosen 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.

32 IMER-REAED ERMINOOGY What is the timer? he 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 (ime delay operation) he 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 (ime delay contact) (In time delay operation) time Off-delay Operation (ime delay resetting) he 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 Flicker Operation he 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 Power supply or signal Output signal (ime delay contact) Output signal (ime delay contact) t t (In time delay operation) time t < t t t t : Output time t : Output time t Star ( )/Delta ( ) Operation his 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 ime he preset time is the control time set by setting time-variable timer. ime he 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 ime It means the time which elapses between the completion of operation for preset time and the start of resetting. Pause ime 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. imer does not perform normal function unless this pause time is set longer than the timer reset time. Resetting 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. Resetting during the operation for preset time is referred to as halfway resetting. Reset ime It means the time elapses between shutoff of input to the power supply circuit or input of reset signal and the completion of resetting. imer 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 impossible to expect the normal operation. herefore, be sure to set the timer pause time longer than the specified reset time. Power supply (Input signal) ime delay contact Internal mechanism Internal circuit Power application time (Input signal application time) time Hold time Pause time Reset time Minimum Power Application ime 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 ime 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 voltage and that within the allowable voltage range. emperature Error It means the difference between the operating time at the temperature of 0± 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. he 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 00 hours is set in the range of 00 hours. he error produced when 0 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 0 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 0 seconds. hen, reset the range to 0 hours, leaving the pointer set at the graduation as it is.

33 Pause ime Error It means the difference between the operating time to a fixed pause time and the operating time to a pause time that varies. he 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 he operation time shall be measured, in principle, for retention time of 0. second and halt time of second. he measurement shall be repeated five times except for the initial test. he equation for each error and the measurement conditions are shown in the table below: M: s: Ms: max: min: Mx : Mx : Mx : Item () Fluctuation in operation time () Voltage error () emperature error () Set error () Pause time error Equation max. min. ± 00 (%) Ms Mx M 00 (%) Ms Mx M 00 (%) Ms M s 00 (%) Ms Mx M 00 (%) Ms IMER-REAED ERMINOOGY Measurement conditions Set value s (Note ) Supply voltage Ambient temperature Full-scale value / or more of full-scale value Full-scale value Rated voltage Fluctuation range of allowable voltage of power supply (Note ) Rated voltage 0± C ± F (Note ) 0 to 0 C + to F (Note ) 0± C ± F (Note ) Note : For digital timers, the set value s shall be optional. Note : If no question arises from evaluation results, - C is acceptable. Note : he measurement may be performed in other specified voltage ranges. Note : he 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 voltage as maximizes deviation from M in allowable voltage range. Average of operation time at such temperature as maximizes deviation from M 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 M. 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 no-load state. Electrical life Means the durability that is achieved when the specified voltage 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. he electrical life is shorter than the mechanical life, and becomes longer as the load decreases. he 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 voltage is applied to the power circuit. (Rated power consumption = rated voltage current consumption) Rated control capacity Means the reference value that is used to determine the performance of the switching part of the load. his value is represented by the combination of voltage 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 voltage 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 voltage Means the limit value that does not cause breakdown when high voltage is applied for one minute to the same location as measured for insulation resistance. he detectable leak current is normally 0 ma. In special cases, however, it may be ma or ma. Withstand surge voltage Means the limit value that shows the durability against momentary abnormal voltage resulting from lightning or switching a conductive load. he surge waveform is represented by the standard impulsive voltage waveform at ±(. 0) µs or ±( 0) µs.

34 PRECAUIS IN USING HE IMERS 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. herefore, it is recommended that the following protective circuit be used to protect the contact point. Circuit Application AC DC Features/Notes Device Selection imer contact. ype of oad and Inrush Current he 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. he table below shows the relationship between typical loads and their inrush currents. ype of load Inrush current Resistive load Steady state current Solenoid load 0 to 0 times the steady state current Motor load to 0 times the steady state current Incandescent lamp load 0 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 0 to 0 times the steady state current ransformer load 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 he PMH and H 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. r CR circuit (r: resistor c: capacitor) c Inductive load imer contact r c (see note.)

35 ) 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 voltage 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 A (Fig. A) PRECAUIS IN USING HE IMERS R R A (Fig. B). Electrical life he electrical life varies depending on the load type, the switching phase, and the ambient atmosphere. In particular, the following cases require careful atten- R tion: () If an AC load is switched in synchronized phases: ocking 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. his may corrode metallic materials. he effective countermeasures include:. Using an arc-extinguishing circuit;. Decreasing the switching frequency; and. 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 voltage must be applied at a time through a switch, a relay, and other parts. If the voltage is applied gradually, the specified time may be reached regardless of its value or the power supply may not be reset. ) he operation voltage for the DC type must be at the specified ripple percentage or less. he average voltage must fall within the allowable operation voltage range. Rectification type Ripple percentage Single-phase, full-wave Approx. % hree-phase, full-wave Approx. % hree-phase, half-wave Approx. % Note: Refer to the ripple percentage of each timer. ) Make sure that no induced voltage and residual voltage 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-voltage and motor lines, induced voltage may be produced between the power pins.). Control output ) he 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. ) he following connection might result in short circuit between the heteropolar contacts in the timer. Bad example Good example. Installing the timer ) o 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 (±. 0µs or ± 0µs) is taken as the standard value for surge-proof voltage. (he positive and negative voltages are applied each three or five times between the power pins.) For the standard values for the PMH, H and SDX type timers, see the respective items in "Cautions for use." Single-pole, full-wave voltage for surge waveform [±(. 0) µs] Crest value (%) Crest value ime (µs) 0 Single-pole, full-wave voltage for surge waveform [±( 0) µs] Crest value (%) Crest value PMH [±( 0) µs] ime (µs) Voltage type Surge voltage AC type (Except for V AC),000V V DC, V DC, V AC 00V V DC,000V 00 to 0V DC,000V If external surge occurs exceeding the specified value, the internal circuit may break down. In this case, use a surge absorption element. he 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 (H series), see the relevant item in "Cautions for use."

Checking the actual load In order to increase the reliability in the actual use, check the quality of the timer in the actual usage. 9. Others ) If the timer is used exceeding the ratings (operation voltage 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.
