Failure

Code

Description

F01 : Inverter

Inverter

Master

F01.01 (A)

COMBIACX : Failure in the high current hardware protection circuit.
Internal fault. Replace the inverter.

COMBIACX : When no current is applied to the traction motor, the current feedbacks are out of
permitted standby range.
Type of default not related to external components.
Cycle power to clear the fault. If the fault is not cleared, replace the controller.

COMBIACX : Driver of main contactor coil is damaged (not able to close).
Type of default not related to external components.
Cycle power to clear the fault. If the fault is not cleared, replace the controller.

COMBIACX : The driver of the electromechanical brake coil is not able to drive the load.
Internal fault. Replace the controller.

COMBIACX : Pump current sensor out of range (at start-up or standby).
Internal fault. Replace the controller.

COMBIACX : At startup, the amplifiers voltage (used to measure the motor voltage) is too low
or too high ( < 2V or > 3 V).
Internal fault. Replace the controller.

Pump

failure

F01.05 (A)

COMBIACX : The software waits for the motor pump to stop at start-up.
If the motor connected to "-P" is still moving, wait for it to be still.
If not, wait 30 seconds until alarm "PUMP VMN NOT OK" appears. Refer to corresponding
alarm chapter.

COMBIACX : Pump driving voltage different than the expected one.
Key OFF / ON.

COMBIACX : The pump motor output voltage is lower than expected, considering the control
applied.
Check the motor power wiring and connections.
Check the motor phases for proper insulation with the chassis.
Check that main contactor drive power contact close properly, with a good contact.
If no problem is found on the motors, replace the controller.

COMBIACX : The pump motor output voltage is higher than expected, considering the control
applied.
Check the motor power wiring and connections.
Check the motor phases for proper insulation with the chassis.
Check that main contactor drive power contact close properly, with a good contact.
If no problem is found on the motors, replace the controller.

COMBIACX : The pump current sensor feedback is always 0 V, even if pump motor is running.
Check the pump motor connection and continuity.
Type of default not related to external components.
Cycle power to clear the fault. If the fault is not cleared, replace the controller.

Overheatin

F01.06 (A)

COMBIACX : The controller has reached thermal cutout (temperature of the controller base
plate is higher than  85°C / 185°F).
Power down and allow to cool. Do not operate in ambient temperatures over to  60°C / 140°F.
Check for jammed or obstructed drive motor. Check for excessively high drive motor current
consumption while driving on the level (over  70°C / 158°F).. Check controller for proper
installation. If the controller is cold when the default appears, replace it.

ACEX : The controller has reached thermal cutout (temperature of the controller base plate is
higher than  85°C / 185°F).
Power down and allow to cool. Do not operate in ambient temperatures over to  60°C / 140°F.
Check for jammed or obstructed drive motor. Check for excessively high drive motor current
consumption while driving on the level (over  70°C / 158°F).. Check controller for proper
installation. If the controller is cold when the default appears, replace it.
