4235 POWER MODULE TOO HOT - REDUCED OPER-
ATION
None 4_2 • DriveState =CREEP
• LiftUpState = CREEP • Heatsink temperature exceeded 185° F (85° C).
• Effect: Reduced drive and brake torque.
• Possible Cause:
•
Controller is performance-limited at this temperature.
• Controller is operating in an extreme environment.
• Excessive load on vehicle
• Improper mounting of controller.
4236 POWER MODULE TOO COLD - MODULE
SHUTDOWN
None 4_2 • DriveState = PREVENTED
• LiftUpState = PREVENTED • Heatsink temperature below -40° F(-40°C).
• Possible Cause:
•
Controller is operating in an extreme environment.
426 MASTER MODULE TEMPERATURE – OUT OF
RANGE
None 4_2 • Normal operation • The Ground Module's internal temperature sensor is out of range. (<
104° F (40° C) or > 302° F (150° C)
441 BATTERY VOLTAGE TOO LOW – SYSTEM
SHUTDOWN
None 4_4 • SafeMode
• LiftDownState = PREVENTED • Battery Voltage(VBAT) momentarily dropped below 14.5V when using
flooded lead-acid batteries, or 16.0V when using AGM batteries. With
a low battery charge, this can occur during heavy current demand due
to Drive, Steer, or Lift Up. Recharge batteries or check for damaged
batteries, sulfated batteries, or poor power connections.
442 BATTERY VOLTAGE TOO HIGH – SYSTEM
SHUTDOWN
None 4_4 • Enter SafeMode
• LiftDownState = MAX • The Ground Module measured excessively high battery voltage (VBAT)
(>32.0V) and de-energized the Main Line Contactor and Battery Relay
to protect system devices and was unable to bring voltage down to
normal operating range. This may be due to improper battery
charging or incorrect voltage batteries being used.
4421 LOGIC SUPPLY VOLTAGE OUT OF RANGE HIGH None 4_4 • Enter SafeMode
• LiftDownState = MAX • The Ground Module's VSW voltage was measured to be more than
32V. This may be caused by loose battery terminal, severely discharge
batteries, a damaged battery, or an improper wire harness connection.
