Setting accuracy: 3% Connect the unit as required. The Connection Diagram below shows a typical installation, whereby the supply to a load is Repeat accuracy: 0.5% at constant conditions being monitored by the Phase monitoring relay. If a fault should occur (i.e. fuse blowing), the relay will de-energise and Immunity from micro power cuts: <50ms assuming control of the external Contactor, de-energise the Contactor as well. Response time (t ): 50ms r Only connect the Neutral if available and 4-wire monitoring is required. Time delay (t): 0.2 10s ( 5%) Note: actual delay (t) = adjustable delay + response time Applying power. Restart/Power on delay (Td): 1s 5m ( 5%) Set the Nominal (Un) voltage selector to match that of the voltage being monitored. Reset time: 50 100ms Set Under % adjustment to minimum. Power on indication: Green LED Set the Delay (t) and Restart Delay adjustments to minimum. Relay status indication: Red LED Apply power and the green Power supply LED will illuminate. The red relay LED will flash and relay remain de- energised for the Power on delay (Td). After this period has elapsed, the LED will remain lit and relay energised. Note the Ambient temperature: -20 to +60C red LED flashes at twice the rate of that when delaying the relay to de-energising. This is to help distinguish the two modes. Relative humidity: +95% max. Refer to the Troubleshooting table if the unit fails to operate correctly. Output (15, 16, 18 / 25, 26, 28): DPDT relay Setting the unit (with power applied). Output rating: AC1 250V 5A (1250VA) Accurate setting can be achieved by adjusting the trip level Under (%) until the unit trips (relay de-energises) then by AC15 250V 2A decreasing the trip level Under (%) until the relay re-energises. Close setting of the trip level ensures the unit will detect a DC1 25V 5A (125W) phase loss even with a large percentage of re-generative voltage. Electrical life: 150,000 ops at rated load In order to set the unit as previously described but without causing disruption to the equipment being Dielectric voltage: 2kV AC (rms) IEC 60947-1 controlled/monitored, set the Delay (t) to maximum. It will now be possible to establish the trip point when the red LED Rated impulse withstand voltage: 4kV (1.2/50S) IEC 60664 starts to flash. Decrease the trip level setting to stop the LED flashing. Housing: Orange flame retardant UL94 (Note: If the time delay is allowed to expire, the output relays will de-energise) Weight: 90g If large supply variations are anticipated, the trip level should be set further from the nominal voltage. Mounting option: On to 35mm symmetric DIN rail to BS EN 60715 or direct Set the Delay (t) and Restart delay as required. (Note that the delay t is only effective should any phases fall below surface mounting via 2 x M3.5 or 4BA screws using the black nd the set trip point. However, if the supply drops below the 2 under voltage trip level, any set time delay is automatically clips provided on the rear of the unit. cancelled and the relays de-energise immediately). 2 Terminal conductor size 2 x 2.5mm solid or stranded Troubleshooting.
