Hysteresis: 2% of trip level (factory set) Connect the unit as required. The Connection Diagram below shows a typical installation, whereby the supply to a load is Setting accuracy: 3% being monitored by the Phase monitoring relay. If a fault should occur (i.e. fuse blowing), the relay will de-energise and Repeat accuracy: 0.5% at constant conditions assuming control of the external Contactor, de-energise the Contactor as well. Immunity from micro power cuts: <50ms Only connect the Neutral if available and 4-wire monitoring is required. Response time (t ): r 50ms Applying power. Time delay (t): 0.2 10s ( 5%) Set the Nominal (Un) voltage selector to match that of the voltage being monitored. Note: actual delay (t) = adjustable delay + response time Set the Asymmetry % adjustment to maximum. Restart/Power on delay (Td): 1s 500s Reset time: 50 100ms Set the Delay (t) and Restart delay adjustments to minimum. Apply power and the green Power supply LED will illuminate. The red LED will illuminate and relay energise after Power on indication: Green LED the short delay period (Td). Relay status indication: Red LED Refer to the troubleshooting table if the unit fails to operate correctly. Ambient temperature: -20 to +60C Setting the unit (with power applied). Relative humidity: +95% max. Assuming all phases are perfectly balanced it should be possible to set the Asymmetry (%) adjustment to minimum which Output (15, 16, 18 / 25, 26, 28): DPDT relay will ensure that it will detect the smallest of changes in the phase voltages. However, if large changes in phase voltages are Output rating: AC1 250V 5A (1250VA) likely, then the Asymmetry (%) setting should be increased. AC15 250V 2A The formula used for calculating phase asymmetry is shown on the right at the bottom of the Technical Specification. DC1 25V 5A (125W) Set the Delay (t) and Restart delay as required. (Note that the delay t is only effective should any phases exceed the Electrical life: 150,000 ops at rated load nd set trip point. However, if the supply drops below the 2 under voltage trip level, any set time delay is automatically Dielectric voltage: 2kV AC (rms) IEC 60947-1 cancelled and the relay de-energises immediately).
