Fault/Log Codes
The following is a list of the possible fault and log codes that can be generated depending on the
type of starter.
The fault class lists the default setting for each fault; either critical or non-critical.
NonC = Non-critical Crit = Critical

Description/Possible Solutions
1 NonC Sequence Not CBA Incoming phase sequence is actually ABC but starter is set to CBA
2 NonC Sequence Not ABC Incoming phase Sequence is actually CBA but starter is set to ABC
3 NonC No Phase Order No phase order detected.
4 NonC High Freq. Trip
Line frequency went above the high freq. trip setting
Line power quality problem.
Low control power problem.
Generator governor is malfunctioning
5 NonC Low Freq. Trip
Line frequency went below the low freq. trip setting
Line power quality problem.
Low control power problem.
Generator governor malfunctioning.
6 NonC Jog Not Allowed
Jog input (JC13-4) was energized while the starter was running.
Stop the starter by removing the run command before requesting a jog
(JC13-4).
7 NonC 100% Not Allowed
The jog input (JC13-4) was de-energized while the starter was
operating in the jog mode.
Stop the starter by removing the run command before removing the jog
command (JC13-4).
9 NonC Dir Change Fault
The jog direction was changed while the starter was operating in the
jog mode.
Stop the starter by removing the run command before changing the
state of the reversing input (JC13-6).
15 Crit Phase Order Err Phase order error.
16 Crit Bad OP Code Err Bad operating-code error
17 NonC Over voltage L1 The voltage on line 1 went above the high/low voltage setting
18 NonC Over voltage L2 The voltage on line 2 went above the high/low voltage setting
19 NonC Over voltage L3 The voltage on line 3 went above the high/low voltage setting
20 NonC Low line voltage#1 The voltage on line 1 went below the high/low voltage setting
21 NonC Low line voltage#2 The voltage on line 2 went below the high/low voltage setting
22 NonC Low line voltage#2 The voltage on line 3 went below the high/low voltage setting
23 NonC Curr. Imbal. HL1 The current on line 1 went above the current imbalance setting
24 NonC Curr. Imbal. HL2 The current on line 2 went above the current imbalance setting
25 NonC Curr. Imbal. HL3 The current on line 3 went above the current imbalance setting
26 NonC Curr. Imbal. LL1 The current on line 1 went below the current imbalance setting
27 NonC Curr. Imbal. LL2 The current on line 2 went below the current imbalance setting
28 NonC Curr. Imbal. LL3 The current on line 3 went below the current imbalance setting
29 Crit Bad RAM Battery
Bad RAM battery.
Replace IC16 or computer card to correct problem.
To clear fault, hold the down arrow key and perform a computer reset.
Continue holding the down arrow key until fault 30 appears on the
display
30 Crit Def Param Loaded
The factory defaults for the parameters have been loaded.
Reset the computer to clear the fault.
All parameters have to be re-programmed as necessary.
31 NonC REV Not Allowed
Starter is not a reversing unit.
Remove reverse command from reverse input (JC13-6).
46 NonC BIST Canceled
The Built-in Self Test was canceled.
The disconnect was closed.
Line power was applied to the starter.
49 NonC Tach Loss
There was no tachometer feedback signal detected when a start was
commanded.
