Mains Failure alarm generate, what should be done?
Solution
Possible Causes:
1) The AC input power cable is faulty.
2) The upper-level AC input circuit breaker is OFF.
3) The mains grid is faulty.

Measures:

1) Check whether the AC input cable is loose. If yes, secure the AC input cable.

2) Check whether the upper-level AC input circuit breaker is OFF. If yes, handle the back-end circuit failure and then switch on the circuit breaker.

3) Check whether the AC input voltage is lower than 50 V AC. If yes, handle the mains grid fault.
