CODE
0X39 Main Contractor Did Not
Close
0X42 Throttle Input
0X46 NV Memory Failure
POSSIBLE CAUSES
Type1:
1. Main contactor did not close.
2. Main contactor tips are oxidized,
burned, or not making good
contact.
3. An external load on the capacitor
bank (B+ connection terminal) is
preventing the capacitor bank from
charging.
4. Blown B+ fuse.
5. Main Contactor parameters
mistuned Main Pull In Voltage,
Main Holding Voltage.
Type2:
1. Main opened during operation
(while commanded closed).
2. Driver wiring to contactor's coil
(e.g., pin 3 wiring) removed during
operation.
3. Contactor/coil defective.
1. Throttle voltage exceeded the
Analog Low or Analog High param-
eters for the analog input defined
for the throttle input.
2. See Programmer » Controller
Setup » Analog Inputs » Analog 1
Type.
3. See Programmer » Controller
Setup » Analog Inputs » Configure.
1. Failure to read or write to
nonvolatile (NV) memory.
2. Internal controller fault.

SET/CLEAR CONDITIONS
Set: With the main contactor
commanded closed, the
capacitor bank voltage (B+
connection terminal) did not
charge to B+.
Clear: Reset Controller.
Set: Throttle voltage exceeded
the Analog Low or Analog
High parameters for the
analog input defined for the
throttle input.
Clear: Bring throttle input volt-
age within the Min and max
thresholds. Reset Controller.
Set: Controller operating
system tried to read or write to
EEPROM memory and failed.
Clear: Download the correct
software and matching
parameter default settings
into the controller and Reset
Controller.
