Solution
35
Proportional Driver
Open/Short
(Proportional Relief
Valve)
1. Open or short on driver load
2. Dirty connector pins
3. Bad crimps or faulty wiring
ShutdownPD
Set: Proportional driver (pin 2) is either
open or shorted
Clear: Correct open or short, and cycle
driver
36
Encoder Fault
1. Motor encoder failure
2. Bad crimps or faulty wiring
3. See Monitor menu » Motor:
Motor RPM
ShutdownEMBrake; Motor
disabled
Set: Motor encoder phase failure
detected
Clear: Either cycle KSI, or if parameter
LOS Upon Encoder Fault= On and
Interlock has been cycled, then the
Encoder Fault is cleared and Encoder
LOS fault (code 93) is set, allowing
limited motor control
37
Motor Open
1. Motor phase is open
2. Bad crimps or faulty wiring
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake
Set: Motor phase U, V, or W detected
open
Clear: Cycle KSI
38
Main Contactor
Welded
1. Main contactor tips are welded
closed
2. Motor phase U or V is
disconnected or open
3. An alternate voltage path (such
as an external precharge resistor)
is providing a current to the
capacitor bank (B+ connection
terminal)
ShutdownEMBrake; Motor
disabled
Set: Motor encoder phase failure
detected
Clear: Cycle Power to KSI
39
Main Contactor Did
Not Close
1. Main contactor did not close
2. Main contactor tips are
oxidized, burned, or not making
good contact
3. External load on capacitor
bank (B+ connection terminal)
that prevents capacitor bank from
charging
4. Blown B+ fuse
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake
Set: Just prior to the main contactor
closing, the capacitor bank voltage
(B+ connection terminal) was loaded
for a short time and the voltage did not
discharge
Clear: Cycle KSI Power
46
EEPROM Failure
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
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
ShutdownInterlock;
ShutdownDriver1,2,3 &4;
ShutdownPD;
FullBrake
Set: Controller operating system tried
to write to EEPROM memory and
failed
Clear: Download the correct software
(OS) and matching parameter default
settings into the controller and cycle
KSI
49
Parameter Change
Fault
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
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake
Set: Adjustment of a parameter setting
that requires cycling of KSI
Clear: Cycle Power to KSI
