Line contactor did not
close
S
Line contactor did not close
when coil is energized.
Check line contactor
condition/wiring.
5
PST fault
DI
Fault detected on PST power
steer module.
Check PST condition.
5
Motor open circuit
S
Unable to establish current in
motor.
Check motor
condition/wiring.
6
Throttle pressed at
power up
DI
Throttle demand is greater than
20% at power up.
Reduce demand
6
Analogue input wire-off
VS
Analogue input voltage is
outside allowable range.
Check analogue
input wiring
6
Analogue output fault
(over/under current,
failsafe, short circuit
driver)
VS
Analogue output fault caused by
over current (>4A), under
current if actual current < 50%
target (current mode only),
failsafe circuit fault, short circuit
driver MOSFET.
Check analogue
output wiring.
7
BDI warning or cut-out
I
BDI remaining charge is less
than warning or cut-out levels.
Charge battery.
7
Battery low voltage
protection
I
Battery voltage or capacitor
voltage is below a user definable
minimum battery level for a user
definable time.
Increase battery
voltage above user
defined level
7
Controller low voltage
protection
I
Battery voltage or capacitor
voltage is below the minimum
level allowed for the controller.
Increase battery
voltage above
minimum level
7
Controller high voltage
protection with line
contactor closed.
I
Battery voltage or capacitor
voltage is above the maximum
level allowed for the controller
with line contactor closed.
Investigate and
reduce battery
voltage below
maximum level.
7
Battery high voltage
protection
I
Battery voltage or capacitor
voltage is above a user
definable maximum battery level
for a user definable time.
Investigate and
reduce battery
voltage below user
defined maximum
level.
7
Motor low voltage
protection
I
Capacitor voltage has entered
the motor low voltage cutback
region defined in 4612
h
.
Increase battery
voltage above start of
motor low voltage
cutback region.
7
Motor high voltage
protection
I
Capacitor voltage has entered
the motor high voltage cutback
region defined in 4612
h
.
Reduce battery
voltage below start of
motor high voltage
cutback region.
