APPENDIX A - ALARM CODES
Alarm Codes
The following is a list of all MX2 SEP 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.

Notes
This occurs when the motor thermal content reaches the
90%. The MX2 SEP trips when it reaches 100%. The
alarm continues until the overload trip lockout is reset.
This alarm exists while the MX2 SEP is stopped, line
voltage is detected and phase sensitivity parameter is set to
ABC. If a start is commanded, a Fault 10 occurs.
This alarm exists while the MX2 SEP is stopped, line
voltage is detected and phase sensitivity parameter is set to
CBA. If a start is commanded, a Fault 11 occurs.
This alarm exists when the MX2 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.
This alarm exists when the MX2 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.
This alarm exists while the MX2 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.
This alarm exists while the MX2 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.
This alarm exists while the MX2 SEP is stopped and low
line voltage is detected. If a start is commanded, a Fault 21
may occur.
This alarm exists while the MX2 SEP is stopped and low
line voltage is detected. If a start is commanded, a Fault 22
may occur.
This alarm exists while the MX2 SEP is stopped and low
line voltage is detected. If a start is commanded, a Fault 23
may occur.
This alarm exists while the MX2 SEP is stopped and high
line voltage is detected. If a start is commanded, a Fault 24
may occur.
This alarm exists while the MX2 SEP is stopped and high
line voltage is detected. If a start is commanded, a Fault 25
may occur.
This alarm exists while the MX2 SEP is stopped and high
line voltage is detected. If a start is commanded, a Fault 26
may occur.
This alarm exists while the MX2 SEP is running and a
phase loss condition is detected, but the delay for the fault
has not yet expired. When the delay expires, a Fault 27
occurs.
This alarm exists while the MX2 SEP needs to be
synchronized or is trying to sync to the line and no line is
detected.
This alarm exists while the MX2 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.
This alarm exists while the MX2 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.
