Basic action process In the automatic state, the fee control signal is detected to be 220V, and the drive switch is closed. The fee control signal 0V is detected, and the switch is opened. (For other details, please refer to the status control table)
Manual/automatic operation If you turn [Manual/Auto] to automatic mode, the payment will be resumed after the arrears are opened, and the payment will be automatically closed, and it will not be automatically closed after other faults are tripped.
If you dial [Manual/Auto] to manual mode, the payment will be resumed after the arrears are opened, and the payment will not be automatically closed, and the payment will not be automatically closed after other faults are tripped.
Light The indicator light is on, indicating that there is no arrears. If the indicator is off, the bill is in arrears or there is no power supply.
