Probable Cause and Consequent Action
• Cause: In standby mode (pump motor not activated), feedback from the current
sensor in the pump impeller provides a value outside the allowable range because the
pump current is not zero.
• Solution:
This type of failure is independent of external components; replace the controller
• Cause: The controller detects a high temperature and the motor performance is
limited.
• Solution:
It is suggested to check the cause of the high temperature. The controller is usually not
installed properly or the fan does not work.
• Cause:
- The motor temperature sensor is not properly connected to A22.
- The motor temperature sensor is damaged.
• Solution:
- Check the correct connection of the motor temperature sensor.
- If the current sensor is connected correctly, replace it.
- If the problem persists, it is the controller's fault.
• Cause: This warning (only present in wagons with a "Dead Man" switch) appears
when the "Dead Man" switch is open.
• Solution: The warning disappears on the next transport application when the dead
man switch is closed.
• Cause: The controller receives from CAN the message that another controller in the
network is faulty; as a result, the ACE-0/ COMBIAC-0 controller is unable to enter the
operational status, but must WAIT for the other controller to exits the fault status.
• Cause: The test is performed when the key is activated 20 seconds after both trans-
port requests have been turned off. This alarm occurs if the ACCELERATOR value
in the TESTER menu is 1.0V higher than the minimum VACC PROGRAM acquisition
when the accelerator is released.
• Solution: Check mechanical calibration and potentiometer operation.
• Cause: Note: When the bar is released, the main contactor opens after a certain
standby period(30 seconds).
• Solution: The warning disappears at the next transport demand.
• Cause: The maximum current gain parameters are set to default values, which
means that the maximum current setting procedure has not yet been performed.
• Solution: Seek assistance from a Zapi technician to perform the proper current ad-
justment procedure for the current gain parameters.
• Cause: Acquisition of current gains
• Solution: The alarm ends when the acquisition is done.
• Cause: It is simply a warning to perform scheduled maintenance.
• Solution: The alarm disappears when the acquisition is completed.
• Cause: The controller's thermal sensor output is out of range.
• Solution: This type of failure is independent of external components; replace the
controller
• Cause: There is an error in the choice of glide profile parameters.
• Solution: Check the value of these parameters in the software settings menu.
