2 GI timers Series GI consists of electronic timers. he power supply does not include a transformer, therefore the timers can be operated either by AC or DC power. he relay operation is indicated by a front-plate LED. Five variants of GI timers are produced according to operation characteristics, with delay times from 0,3 s to 30 h in time ranges. he operating power can be of four different rated voltages. Altogether the series consists of 220 different timers but all have unified circuits and structure. Ordering information: GIM 60s 230 Operation mode M: delayed operation F: delayed release : delayed switch-off L: falling edge controll B: flashing Operation Upper limit of delay and possible delay times 3s: 0, s 3m: 0, min 3h: 0, h 6s: 0, s 6m: 0, min 6h: 0, h 30s: s 30m: min 30h: h 60s: s 60m: min Connecting Rated operating supply voltage 230: 230 V AC, DC 0: 0 V AC, DC 42: 42 V AC, 48 V DC 24: 24 V AC, DC he indication of the connecting terminals is according to the method used in Europe (DI 4699): - phase conductor of the network or its positiv wire is connected to A - neutral conductor of the network or its negative wire is connected to A2 - starting is operated on connecting terminals B, B2 - he output contacts of the relay are connected to 6,, 8, and 26, 2, 28 A2 and B2 connecting terminals Startsignal are connected within the device, therfore it is practical to connect the neutral wire to A2, A 2 B B2 so that phase voltage would not apper on B2 as well. he prevailing rectified rated control supply voltage appears connecting terminal B, that is why the starting contact has to A B A2B be capable to switch the Uc A2 voltage safely, and must have at least Uc insulation voltage. he flowing current on starting contact is roughly 0,3 ma. Starting can be made in two ways: starting by contacts: make short B and B2 contacts at least 0, s after connecting the operating power. he minimum power-off time after the timing is 0 ms. power starting: having made B and B2 short, connect the operating power. his method can be used with types GIM, GIF and GIB only. 0 ms is added to the delay time in this case. he minimum power-off time after the timing is 300 ms. If the power fails for more than 300 ms, the timers will set to their basic condition, and will work as power-started timers when the power is back. If the power fails for less than 0 ms, the timing will be continued after the power is back.

6 U... three-phase voltage relays he U... relays can protect three-phase equipments (mainly motors) against asymmetry and false sequence of line voltages as much as asymmetrical increase or decrease of line voltages. heir operation dos not require neutral conductor. urn-off thresold value of asymmetry, voltage increase and decrease failures can be set by the front-plate knobs. urnoff is delayed so that the relay is not sensitive to voltage transients. Since the four protection modes are optional, they must be ordered as follows: First character of ordering code is U. he following characters are combination of the required protection: A - phase asymmetry S - phase sequence - line voltage increase C - line voltage decrease combinations of the 4 modes are possible. Ordering codes: UA UAS UAS UASC US UA UASC U UAC UAC UC US USC USC UC he delay can not be adjustable at the above mentioned types. he delay time of the turn-off can be set by the frontplate knob of the types UAt, UASt and UASCt. Application Protection against line voltage decrease does not protect against phase loss. hese task can be performed by phase asymmetry protection. Asymmetry means the maximum difference of the line voltages related to the highest line voltage, expressed in per cent. In case of normal supply voltage the output contact is closed, the green front-plate LED is on. One red LED corresponds to each protection mode. In case of phase failure the relevant LED turns on, the green LED turns off and the output opens. If the U relay performs phase sequence protection, care must be taken when connecting phase wires so that the green LED is on at right phase sequence. In case of altering the phase sequence the output contact immediately opens. If the phase sequence is wrong when the relay turned on the output contact does not close. Operation In case of normal supply voltage the output contact of the built-in relay is closed, the green front-plate LED is on. Range of delay of non adjustable types is between 0. s and s, if the failure is great (e.g. phase-loss) the relay turns off faster. One red LED corresponds to each (max. four) protection mode. If one or more failure occur, the relevant red LED begins to illuminate, the green LED turns off and the contacts of the built-in relay break. At adjustable types: - if one or more failure occur the relevant LED begins to flash, - if the failure breaks within delay time the faultless situation returns, - the failure does not break within delay time then the flash of the relevant LED changes the continuous, the contacts of the built-in relay break and the illumination of the twocoloured LED changes from green to red light.

8 UC single-phase voltage relay he UC single-phase voltage relay is designed to monitor loss, increase or decrease of 230 VAC mains voltage. Application, functions In case of normal mains voltage conditions the output contact is closed, indicated by on-state green LED(). If the mains voltage falls under the value set by knob (2) or exceeds the value set by knob (4) the output contact opens and the LED's besides the knobs turn on indicating type of failure. In order to eliminate malfunction by voltage transients the operation of the relay is delayed. Delay time is 0,... 2 s depending on the extent of voltage deviation. Values of voltage incease and decrease at the frontplate knobs are for information. he required values can be set exactly by measurement at installation. he switching mode power supply of the relay requires appr. 0,2 A for appr. ms at each half cycle. his must be taken into consideration. For example if a transformer is used for galvanic separation, its power must be min. 630 VA in order to avoid distortion of monitored voltage.

10 VH overheat protection relay he VH relay is intended to protect industrial electric equipments (first af all motors, but also electric furnaces, welding, X-ray equipments, etc.) against harmful overheating. Principle of operation he VH relay is activated by the change of the resistance of the external sensor, a PC (positive thermocoefficient) thermistor at nominal temperature. he characteristic of the PC allows series connection of several PC's of different nominal temperature without loss of operating precision. Features of PC protection (compared with bimetallic protection): - one VH relay can protect both winding and bearings of a motor; - it is impossible to disable the operation of the relay or to destroy the efficiency and precisity of protection by improper handling; - protection can be performed in case of failures that do not cause harmful increase of current consumption of the motor (e.g. the motor is operated at high ambient temperature or ventillation is blocked; - while utilizing maximum power of the motor protection is guaranteed against heavy starting, repeated breaking, phase failure, too high or too low supply voltage, high or changing switching rate. Application PC thermistors are mounted to the relevant parts of the equipments to be protected (in case of motors into each phase of the stator windings). he output of the PC is connected to VH relay. At nominal temperature the output contact opens and turns off the contactor of the protected equipment, the front-panel LED is off. o As soon as the PC cooled down 2... C, the output contact is closed again and the protected equipment is automatically switched on. If the VH relay is applied according to connection diagram, the output contact is closed after cooling down but the contactor remains in off state. Restart of contactor (and thus the protected equipment) takes place by depressing push-button O. he VH relay must be placed as close to the protected equipment as possible. Cross-section of the connecting wire is min. 0,7 mm 2, max. resistance is 2, ohm. Shielded and possibly the shortest wires are suggested if protection against magnetic or electric interference is necessary. he connecting wires must be placed as far from high-current conductors as possible. Mounting of PC thermistors Maximum allowed initial resistance of applicable PC thermistors is 800 ohm. hermal resistance between thermistor and protected equipment must be minimized. Body of PC thermistors must not be additionally isolated. erminations of the thermistor and the connecting wires must have equal insulation properties to those of protected equipment. Motors are normally supplied with thermistors built into the windings of the motor. Assembling thermistors into the motor needs special skill and therefore can only be done by manufacturer of the motor or by specialised service.
