BEFORE INSTALLATION, ISOLATE THE SUPPLY. 44.5 - 82.5V AC (4-wire) 44.5V 48 - 79V 93 - 173V AC (4-wire) 93V 100 - 166V Connect the unit as required. The diagram below shows a typical installation, whereby the supply to 161 - 300V AC (4-wire) 161V 173 - 288V the load is being monitored by the relay. If a fault should occur, the contactor is de-energised Repeat accuracy: 0.5% constant conditions removing the 3-phase supply to the load. The contactor only re-energises after the fault has cleared. Hysteresis: 2% of trip level (factory set) Applying power. Response time: 50 mS Set the trip level and the time delay to minimum. Time delay (t): 0.2 - 10 sec ( 5%) Apply power and the green supply on and red relay LEDs will illuminate, the relay will energise Note: actual delay (t) = adjustable delay + response time and contacts 15 and 18 / 25 and 28 will close. Refer to troubleshooting table if the unit fails to operate Delay from correctly. phase/neutral loss (tr): 100 mS (worst case = tr x 2) Power on delay (Td): 1sec. (worst case = Td x 2) Setting the unit. Accurate setting can be achieved by adjusting the trip level until the unit trips (relay de-energises) Ambient temp: -20 to +60C then by decreasing the trip level setting until the relay re-energises. By close setting of the trip Relative humidity: +95% level, the unit will also detect a phase loss even with a large percentage of re-generative voltage. Output: DPDT relay (15, 16, 18 / 25, 26, 28) In order to set the unit as previously described but without causing disruption to the equipment being Output rating: AC1 250V 8A (2000VA) controlled/monitored, set the time delay to maximum. It will now be possible to establish the trip AC15 250V 3A point when the red relay LED starts to flash. Decrease the trip level setting to stop the LED flashing. DC1 25V 8A (200W) (Note: If the time delay is allowed to expire, the output relay will de-energise). Electrical life: 150,000 ops at rated load If large supply variations are anticipated, the trip level should be set further from the nominal Dielectric voltage: 2kV AC (rms) IEC 60947-1 voltage. Rated impluse withstand voltage: 4kV (1.2 / 50S) IEC 60664 Set the time delay as required. (Note that the delay is only effective should the supply drop below nd the set trip level. However, if during an under voltage condition the supply drops below the 2 Housing: Orange flame retardant UL94 VO under voltage trip level, any set time delay is automatically cancelled and the relay de-energises).
