If the Curtis Instruments Controller displays a MAIN FAULT, it could be due to a main contactor that is welded or stuck open, so replace the main contactor. Another possible cause is a fault in the main contactor driver, so inspect and repair or replace the main contactor driver.
What to do if Curtis Instruments Controller shows a THERMAL FAULT?
If the Curtis Instruments Controller displays a THERMAL FAULT, it could be due to several reasons. First, check the environment temperature to ensure it is between -10°C and 80°C. Second, reduce the load on the vehicle to prevent overheating. Third, avoid operating the vehicle in extreme environments. Finally, inspect and repair the electromagnetic brake if it is not releasing properly.
How to fix Curtis Instruments Controller BRAKE ON FAULT?
To resolve a BRAKE ON FAULT on the Curtis Instruments Controller, first inspect and repair the electromagnetic brake driver if it is shorted. Also, inspect and replace the electromagnetic brake coil if it is open.
What to do if Curtis Instruments Controller shows SPEED POT FAULT?
If the Curtis Instruments Controller is showing a SPEED POT FAULT, inspect and repair the speed limit pot wiring if it's broken or shorted. If the wiring is fine, the speed limit pot itself might be broken and needs replacement.
What causes Curtis Instruments Controller HARDWARE FAILSAFE?
A HARDWARE FAILSAFE on the Curtis Instruments Controller can be caused if the motor voltage does not correspond to the throttle request, so ensure motor voltage corresponds to throttle request. It can also be caused by a short in the motor or motor wiring, so inspect for shorts in motor or wiring. In some cases, this fault indicates a controller failure, so replace the controller if faulty.
How to troubleshoot Curtis Instruments Controller HPD FAULT?
To troubleshoot an HPD FAULT on a Curtis Instruments Controller, ensure the correct sequence of throttle and KSI inputs. Also, check for a misadjusted throttle pot and adjust it properly.
What to do if Curtis Instruments Controller has WIRING FAULT?
If your Curtis Instruments Controller is showing a WIRING FAULT, you should first check if the throttle is misadjusted and adjust it properly. Also, the throttle pot or throttle mechanism might be broken, so replace them if necessary.
What causes Curtis Instruments Controller CURRENT SENSE FAULT?
A CURRENT SENSE FAULT in the Curtis Instruments Controller can be triggered by a short in the motor or motor wiring, so inspect for shorts in the motor or wiring. In some cases, this fault indicates a controller failure, so replace the controller if faulty.
What to do if Curtis Instruments Controller shows THROTTLE FAULT?
If a Curtis Instruments Controller displays a THROTTLE FAULT, first inspect the throttle input wiring for any opens or shorts. Next, if the wiring is intact, the throttle pot may be defective and require replacement. Lastly, ensure that the correct throttle type is selected for the controller.
Why Curtis Instruments Controller shows UNDERVOLTAGE FAULT?
An UNDERVOLTAGE FAULT on the Curtis Instruments Controller typically occurs when the battery voltage drops below 17 volts, so charge the battery. It can also be caused by a bad connection at the battery or controller, so inspect and repair these connections.
