Fault/Log Codes - McQuay WSC Operating Manual

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.

Description/Possible Solutions
Incoming phase sequence is actually ABC but starter is set to CBA
Incoming phase Sequence is actually CBA but starter is set to ABC
No phase order detected.
Line frequency went above the high freq. trip setting
Line power quality problem.
Low control power problem.
Generator governor is malfunctioning
Line frequency went below the low freq. trip setting
Line power quality problem.
Low control power problem.
Generator governor malfunctioning.
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).
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).
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).
Phase order error.
Bad operating-code error
The voltage on line 1 went above the high/low voltage setting
The voltage on line 2 went above the high/low voltage setting
The voltage on line 3 went above the high/low voltage setting
The voltage on line 1 went below the high/low voltage setting
The voltage on line 2 went below the high/low voltage setting
The voltage on line 3 went below the high/low voltage setting
The current on line 1 went above the current imbalance setting
The current on line 2 went above the current imbalance setting
The current on line 3 went above the current imbalance setting
The current on line 1 went below the current imbalance setting
The current on line 2 went below the current imbalance setting
The current on line 3 went below the current imbalance setting
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
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.
Starter is not a reversing unit.
Remove reverse command from reverse input (JC13-6).
The Built-in Self Test was canceled.
The disconnect was closed.
Line power was applied to the starter.
There was no tachometer feedback signal detected when a start was
commanded.
