Chapter 2 Alarm
Handling Procedure
1.
Improve the power supply quality of the equipment room;
2.
If the detected AC voltage value is lower than the threshold value for alarm of AC
voltage being low, then appropriately decrease the threshold value;
3.
Check whether the AC transducer's connection is normal and whether the transducer
has no problem;
4.
Check whether the monitoring unit's socket is inserted properly;
5.
Replace the monitoring unit.
