The Connection Diagram below shows a typical installation, whereby the supply to 415V 265V 311 394V 436 519V a load is being monitored by the Phase monitoring relay. If a fault should occur (i.e. fuse blowing), the relay will 4-wire (L>N) 220V 140V 165 209V 231 275V de-energise and assuming control of the external Contactor, de-energise the Contactor as well. 230V 147V 173 219V 242 288V 240V 153V 180 228V 252 300V Only connect the Neutral if available and 4-wire monitoring is required. Hysteresis: 2% of trip level (factory set) Applying power. Setting accuracy: 3% Set the Nominal (Un) voltage selector to match that of the voltage being monitored. Repeat accuracy: 0.5% at constant conditions Immunity from micro power cuts: <50ms Set the Over % adjustment to maximum and the Under % adjustment to minimum. Set the Delay (t) Response time (tr): 50ms to minimum. Time delay (t): 0.2 10s ( 5%) Apply power and the green Power supply LED will illuminate. Both the red RLY1 /RLY2 LEDs will Note: actual delay (t) = adjustable delay + response time illuminate and corresponding RLY1 and RLY2 relays energise after the short Power on delay (Td). Power on delay (Td): 1s (worst case = Td x 2) Refer to the Troubleshooting table if the unit fails to operate correctly. Reset time: 50 100ms Power on indication: Green LED Setting the unit (with power applied). Relay status indication: Red LED x2 Set the Over % and the Under % adjustments to give the required monitoring range. Ambient temperature: -20 to +60C If large supply variations are anticipated, the adjustments should be set further from the nominal voltage. Relative humidity: +95% max. Set the Delay (t) adjustment as required. (Note that the delay is only effective should the supply increase Output (15, 16, 18 / 25, 26, 28): 2 x SPDT relay above or drop below the set trip levels.
