Repeat accuracy: 0.5% at constant conditions Connect the unit as required. The Connection Diagram below shows a typical installation, whereby the supply to Immunity from micro power cuts: <50ms a load is being monitored by the Voltage monitoring relay. If a fault should occur (i.e. fuse blowing), the relay will Response time: 50ms de-energise and assuming control of the external Contactor, de-energise the Contactor as well. Time delay (t): 0.2 10s ( 5%) Note: actual delay (t) = adjustable delay + response time Applying power. Power on delay (Td): 1s (worst case = Td x 2) Set the Nominal (Un) voltage selector to match that of the voltage being monitored. Reset time: 50 100ms Set the Over % adjustment to maximum and the Under % adjustment to minimum. Set the Delay (t) Power on indication: Green LED to minimum. Relay status indication: Red LED x2 Apply power and the green Power supply LED will illuminate. Both the red RLY1 /RLY2 LEDs will Ambient temperature: -20 to +60C illuminate and corresponding RLY1 and RLY2 relays energise after the short Power on delay (Td). Relative humidity: +95% max. Refer to the Troubleshooting table if the unit fails to operate correctly. Output (15, 16, 18 / 25, 26, 28): 2 x SPDT relay Output rating: AC1 250V 5A (1250VA) Setting the unit (with power applied). AC15 250V 2A Set the Over % and the Under % adjustments to give the required monitoring range. DC1 25V 5A (125W) If large supply variations are anticipated, the adjustments should be set further from the nominal voltage. Electrical life: 150,000 ops at rated load Set the Delay (t) adjustment as required. (Note that the delay is only effective should the supply increase Dielectric voltage: 2kV AC (rms) IEC 60947-1 above or drop below the set trip levels. However, if during an under voltage condition the supply drops below Rated impulse withstand voltage: 4kV (1.2/50S) IEC 60664 nd the 2 under voltage trip level, any set time delay is automatically cancelled and both relays de-energise Housing: Orange flame retardant UL94 immediately).
