EFFECT OF FAULT
POSSIBLE CAUSE SET / CLEAR CONDITIONS
47 HPD/Sequencing Fault
ShutdownThrottle.
1. KSI, interlock, direction, and throttle
inputs applied in incorrect sequence.
2. Faulty wiring, crimps, or switches at KSI,
interlock, direction, or throttle inputs.
3. See Monitor menu » Inputs.
Set: HPD (High Pedal Disable) or sequencing fault
caused by incorrect sequence of KSI, interlock,
direction, and throttle inputs.
Clear: Reapply inputs in correct sequence.
47 Emer Rev HPD
ShutdownThrottle;
ShutdownEMBrake.
4. Emergency Reverse operation has
concluded, but the throttle, forward and
reverse inputs, and interlock have not
been returned to neutral.
Set: At the conclusion of Emergency Reverse, the
fault was set because various inputs were not
returned to neutral.
Clear: If EMR_Interlock = On, clear the interlock,
throttle, and direction inputs. If EMR_Interlock = Off,
clear the throttle and direction inputs.
49 Parameter Change Fault
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake.
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.
Set: Adjustment of a parameter setting that requires
cycling of KSI.
Clear: Cycle KSI.
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.
Set: See OEM documentation.
Clear: See OEM documentation.
68 VCL Run Time Error
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
ShutdownInterlock;
ShutdownDriver1;
ShutdownDriver2;
ShutdownDriver3;
ShutdownDriver4;
ShutdownPD;
FullBrake.
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.
Set: Runtime VCL code error condition.
Clear: Edit VCL application software to fix this error
condition; ash the new compiled software and
matching parameter defaults; cycle KSI.
69 External Supply Out of Range
None, unless a fault action is
programmed in VCL.
1. External load on the 5V and 12V supplies
draws either too much or too little
current.
2. Fault Checking Menu parameters Ext
Supply Max and Ext Supply Min are
mis-tuned.
3. See Monitor menu » Outputs: Ext Supply
Current.
Set: The external supply current (combined current
used by the 5V supply [pin 26] and 12V supply
[pin 25]) is either greater than the upper current
threshold or lower than the lower current threshold.
The two thresholds are defined by the External
Supply Max and External Supply Min parameter
settings (page 54).
Clear: Bring the external supply current within range.
71 OS General
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
ShutdownInterlock;
ShutdownDriver1;
ShutdownDriver2;
ShutdownDriver3;
ShutdownDriver4;
ShutdownPD;
FullBrake.
1. Internal controller fault. Set: Internal controller fault detected.
Clear: Cycle KSI.
72 PDO Timeout
ShutdownThrottle;
CAN NMT State set to
Pre-operational.
1. Time between CAN PDO messages
received exceeded the PDO Timeout
Period.
Set: Time between CAN PDO messages received
exceeded the PDO Timeout Period.
Clear: Cycle KSI or receive CAN NMT message.
