1. Check system for over-voltage cause
2. Increase the percent over-voltage setting if necessary
3. Increase the fault interrogation time if necessary
1. Turn OFF all power
2. Swap any 2 phases on the load side of the Monitor
only (example: swap load 1 and load 2)
3. Re-apply power
1. Press the READ button to observe the present load
voltages. Check system for unbalanced cause
2. Increase the fault interrogation time if necessary
3. Increase the percent unbalance setting if necessary
1. Check system for under-voltage cause
2. Increase the percent under-voltage setting if
necessary
3. Increase the fault interrogation time if necessary
(example:
2. Repair the missing phase
1. Press and hold the READ button on the phase
monitor or use an AC voltmeter to carefully measure
all three phase-phase line voltages
