Table 7.18 – Sensor Wiring Error Code Table
Error Code Error Suggested Corrective Action
0 No Error No corrective action required.
1 Self Test In Progress
No correction action required. Typically the self test will
complete and auto clear in less than 10 seconds after
power up.
2 Line Voltage Synch
Turn off unit and check 3 phase AC input voltage wiring for
missing phase connection or low line voltage
3 Input Over Voltage
Turn off unit and check 3 phase AC input voltage wiring for
high line voltage
4
Reverse Voltage Phase
Rotation Turn off unit and check 3 phase AC input voltage wiring for
A,B,C phase rotation or missing phase connection
5 Phase A Input Under Voltage
Turn off unit and check 3 phase AC input voltage wiring for
missing phase or low line voltage
6 Phase B Input Under Voltage
Turn off unit and check 3 phase AC input voltage wiring for
missing phase or low line voltage
7 Phase C Input Under Voltage
Turn off unit and check 3 phase AC input voltage wiring for
missing phase or low line voltage
8 Reverse CT Current Rotation
Turn off unit and check system CT feedback for A,B,C
phase rotation, inverted CT polarity, or CT short/open
9 Phase A CT Under Current
Turn off unit and check system CT feedback for no
feedback (CT short or open)
10 CT Under Current
Turn off unit and check system CT feedback for no
feedback (CT short or open)
11 Phase C CT Under Current
Turn off unit and check system CT feedback for no
feedback (CT short or open)
12 Phase A CT Polarity
Turn off unit and check system CT phase A feedback for
incorrect polarity or reverse phase rotation
13 CT Polarity
Turn off unit and check system CT phase A and C
feedback for incorrect polarity or reverse phase rotation
14 Phase C CT Polarity
Turn off unit and check system CT feedback phase C for
incorrect polarity or reverse phase rotation
15 Phase Power Imbalance
Turn off unit and check CT feedback and 3 phase AC
input voltage for incorrect polarity or reverse phase
rotation
