Display/ Effect Of Fault
Possible Cause(s) Set/Clear Conditions
91 VCL/OS Mismatch
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
ShutdownInterlock;
ShutdownDriver1;
ShutdownDriver2;
ShutdownDriver3;
ShutdownDriver4;
ShutdownPD; FullBrake;
ShutdownPump.
1. The VCL software in the
controller does not match the
OS software in the controller.
Set: VCL and OS software do
not match; when KSI cycles,
a check is made to verify that
they match and a fault is
issued when they do not.
Clear: Download the correct
VCL and OS software into the
controller.
92 EM Brake Failed to Set
ShutdownEMBrake;
ShutdownThrottle.
Position Hold is engaged
when Interlock=On.
1. Vehicle movement sensed
after the EM Brake has been
commanded to set.
2. EM Brake will not hold the
motor from rotating.
Set: After the EM Brake was
commanded to set and time has
elapsed to allow the brake to
fully engage, vehicle movement
has been sensed.
Clear: Activate the throttle.
93 Encoder LOS (Limited
Operating Strategy)
Enter LOS control mode.
1. Limited Operating Strategy
control mode has been
activated, a result of either an
Encoder (Code 36) or a Stall
Detect (Code 73).
2. Motor encoder failure.
3. Bad crimps or faulty wiring.
4. Vehicle is stalled.
Set: Encoder Fault (Code 36)
or Stall Detect Fault (Code
73) was activated, and Brake
or Interlock has been applied
to activate LOS control mode,
allowing limited motor control.
Clear: Cycle KSI or, if LOS
mode was activated by the
Stall Fault, clear by ensuring
encoder senses proper
operation, Motor RPM = 0, and
Throttle Command = 0.
94 Emer Rev Timeout
ShutdownEMBrake;
ShutdownThrottle.
1. Emergency Reverse was
activated and concluded
because the EMR Timeout
timer has expired.
2. The emergency reverse input
is stuck On.
Set: Emergency Reverse was
activated and ran until the
EMR Timeout timer expired.
Clear: Turn the emergency
reverse input Off.
98 Illegal Model Number
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake; ShutdownPump.
1. Model_Number variable
contains illegal value. For
1234E/36E/38E models, a
value other than 1234, 1236,
1238, or 1298 is illegal. For
1232E models, a value other
than 1232 is illegal.
2. Software and hardware do not
match.
3. Controller defective.
Set: Illegal Model_Number
variable; when KSI cycles,
a check is made to conrm
a legal Model_Number, and
a fault is issued if one is not
found.
Clear: Download appropriate
software for your controller
model.
