Alarm Codes
The following is a list of all MX
2
alarm codes. The alarm codes correspond to associate fault codes. In general,
an alarm indicates a condition that if continued, will result in the associated fault.

Description Notes
A02 Motor Overload Alarm
This occurs when the motor thermal content reaches 90%. The MX
2
SEP
trips when it reaches 100%. The alarm continues until the overload trip
lockout is reset
A10 Phase Rotation not ABC
This alarm exists while the MX
2
SEP is stopped, line voltage is detected
and phase sensitivity parameter is set to ABC. If a start is commanded, a
Fault 10 occurs.
A11 Phase Rotation not CBA
This alarm exists while the MX
2
SEP is stopped, line voltage is detected
and phase sensitivity parameter is set to CBA. If a start is commanded, a
Fault 11 occurs.
A12 Low Line Frequency
This alarm exists when the MX
2
SEP has detected a line frequency below
the user defined low line frequency level. The alarm continues until either
the line frequency changes to be in range or the fault delay timer expires.
A13 High Line Frequency
This alarm exists when the MX
2
SEP has detected a line frequency
above the user defined high line frequency level. The alarm continues
until either the line frequency changes to a valid frequency or the fault
delay timer expires.
A14 Input power not single phase
This alarm exists while the MX
2
SEP is stopped, set to single phase
mode, and line voltage is detected that is not single phase. If a start is
commanded, a Fault 14 occurs.
A15 Input power not three phase
This alarm exists while the MX
2
SEP is stopped, set to a three-phase
mode, and single-phase line voltage is detected. If a start is commanded,
a Fault 15 occurs.
A21 Low Line L1–L2
This alarm exists while the MX
2
SEP is stopped and low line voltage is
detected. If a start is commanded, a Fault 21 may occur.
A22 Low Line L2–L3
This alarm exists while the MX
2
SEP is stopped and low line voltage is
detected. If a start is commanded, a Fault 22 may occur.
A23 Low Line L3–L1
This alarm exists while the MX
2
SEP is stopped and low line voltage is
detected. If a start is commanded, a Fault 23 may occur.
A24 High Line L1–L2
This alarm exists while the MX
2
SEP is stopped and high line voltage is
detected. If a start is commanded, a Fault 24 may occur.
A25 High Line L2–L3
This alarm exists while the MX
2
SEP is stopped and high line voltage is
detected. If a start is commanded, a Fault 25 may occur.
A26 High Line L3–L1
This alarm exists while the MX
2
SEP is stopped and high line voltage is
detected. If a start is commanded, a Fault 26 may occur.
A27 Phase Loss
This alarm exists while the MX
2
SEP is running and a phase loss condi-
tion is detected, but the delay for the fault has not yet expired. When the
delay expires, a Fault 27 occurs.
A28 No Line
This alarm exists while the MX
2
SEP needs to be synchronized or is try-
ing to sync to the line and no line is detected.
A31 Overcurrent
This alarm exists while the MX
2
SEP is running and the average current
is above the defined threshold, but the delay for the fault has not yet
expired. When the delay expires, a Fault 31 occurs.
A34 Undercurrent
This alarm exists while the MX
2
SEP is running and the average current
is below the defined threshold, but the delay for the fault has not yet
expired. When the delay expires, a Fault 34 occurs.
