The principle of trip and reclose

Under mode AUTO, and the circuit be open, the device will run “AUTO”mode to reclose the circuit after 10 seconds;The device will continue for second reclose after 60s if failed to reclose, and third reclose after 300s. The device will be in “lock”mode after 3 times of reclose and failed(the circuit can’t hold for 15 minutes is defined as failed to reclose).

Release “LOCK”

Both operations above will release the “LOCK”:

1) After visit at site and solved the faulty problem, the electrician needs to switch “AUTO” to “MANU”and “AUTO”again;

2) Remotely open and close once;

Auto/Manu/LockOperationMode
