Instructions for Use
1. When the power is connected, the green indicator light illuminates, indicating that the instrument is in working condition.
2. When a power overload occurs, the ****** indicator light (P>) illuminates, indicating that the power has exceeded the set point and is in a power overload state. After a set time delay, the red indicator light (RELAY) illuminates, indicating that the relay (C) has activated and changed its state.
3. When the reverse power exceeds the set point, the ****** indicator light (P<) illuminates. After a set time delay, the red indicator light (RELAY) illuminates, indicating that the relay has activated and changed its state.
4. The reverse power relay has an inverse time characteristic.
