Pot Low Overcurrent
ShutdownThrottle;
Full Brake.
1. See Monitor menu Outputs: Pot Low.
2. Combined pot resistance connected to pot low is too low.

1. Failure to write to EEPROM memory. This can be caused by EEPROM
memory writes initiated by VCL, by the CAN bus, by adjusting parameters
with the programmer, or by loading new software into the controller.
47
HPD/Sequencing Fault
Shutdown Throttle.
1. KSI, interlock, direction, and throttle inputs applied in incorrect se
-
quence.
2. Faulty wiring, crimps, or switches at KSI, interlock, direction, or throttle
inputs.
3. See Monitor menu Inputs.

Emer Rev HPD
Shutdown Throttle;
Shutdown EM Brake.
1. Emergency Reverse operation has concluded, but the throttle, forward
and reverse inputs, and interlock have not been returned to neutral.
49
Parameter Change Fault
Shutdown Motor;
Shutdown Main Contactor;
Shutdown EM Brake;
Shutdown Throttle;
Full Brake;
Shutdown Pump.
1. This is a safety fault caused by a change in certain parameter settings so
that the vehicle will not operate until KSI is cycled. For example, if a user
changes the Throttle Type this fault will appear and require cycling KSI
before the vehicle can operate.
51-67
OEM Faults
(See OEM documentation.)
1. These faults can be defined by the OEM and are implemented in the
application-specific VCL code. See OEM documentation.

VCL Run Time Error
Shutdown Motor;
Shutdown Main Contactor;
Shutdown EM Brake;
Shutdown Throttle;
Shutdown Interlock;
Shutdown Driver1;
Shutdown Driver2;
Shutdown Driver3;
Shutdown Driver4;
Shutdown PD;
Full Brake;
Shutdown Pump.
1. VCL code encountered a runtime VCL error.
2. See Monitor menu Controller: VCL Error Module and VCL Error. This
error can then be compared to the runtime VCL module ID and error code
definitions found in the specific OS system information file.
