Alarm Codes
The following is a list of all MX 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 the
Motor OL Alarm Level (PFN33). The MX
3
trips when it
reaches 100%. The alarm continues until the overload trip
lockout is reset.
A05
Motor PTC Alarm
This occurs when the Motor PTC thermistor input indicates
that the motor is overheated but before the fault trip time
has expired.
A06
Stator RTD Alarm
This occurs when a RTD assigned to the Stator group
reaches its alarm level.
A07
Bearing RTD Alarm
This occurs when a RTD assigned to the Bearing group
reaches its alarm level.
A08
Other RTD Alarm
This occurs when a RTD assigned to the other group
reaches its alarm level.
A10
Phase Rotation not ABC
This alarm exists while the MX
3
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
3
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
3
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
3
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
3
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
3
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
3
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
3
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
3
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
3
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
3
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
3
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
3
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.
A28
No Line
This alarm exists while the MX
3
needs to be synchronized
or is trying to sync to the line and no line is detected.
