Fault Type(s): 1
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 circuit to B+) is
providing a current to the capacitor
bank (B+ connection terminal).
Set: Just prior to the main
contactor closing, the capacitor
bank voltage (B+ connection
terminal) was loaded (via the
motor) for a short time and
the voltage did not discharge,
indicating a direct-contact to
the battery (i.e., Main tips are
welded closed).
Clear: Reset Controller.

Fault Type(s):
1 = Main did not close when
commanded
2 = Main disconnected during
operation
Type 1:
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.
Type 2:
1. Main contactor 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.
Set: With the main contactor
commanded closed, the
capacitor bank voltage (B+
connection terminal) did not
charge to B+.

parameters for the analog input
dened for the throttle input.
2. See Programmer » Controller
Setup » Inputs » Analog 1 Type.
3. See Programmer » Controller
Setup » Inputs » Congure.
Set: Throttle voltage exceeded
the Analog Low or Analog High
parameters for the analog input
dened for the throttle input.
Clear: Bring throttle input
voltage within the Min and max
thresholds. Reset Controller.

diagnostics may be out
of range if it is congured
as a voltage input or may
include potentiometer faults if
congured as a 2/3-wire pot.
