What to do if Curtis 1226 Controller displays NV memory failure?
If the Curtis Controller displays an 'NV Memory Failure', it means there's a failure to read or write to nonvolatile (NV) memory, or there's an internal controller fault. Download the correct firmware and default parameter settings, then cycle the keyswitch.
What does Curtis 1226 parameter out of range mean?
If the Curtis Controller displays 'Parameter Out Of Range', it means a parameter is set to an invalid value. Update the parameter to a valid value.
What does it mean if Curtis 1226 shows main contactor welded and what to do?
If the Curtis Controller indicates that the main contactor is welded, it means the main contactor tips are welded closed, motor phase M1 or M2 is disconnected or open, or an alternate voltage path is providing current to the capacitor bank. Address the possible causes, then cycle the keyswitch.
What does Curtis Controller EMR Switch Redundancy mean?
If the Curtis Controller displays 'EMR Switch Redundancy', it means either or both Emergency Reverse input switches are inoperative, resulting in an invalid state, or there is dirt or moisture in the switches. Address the possible causes, then cycle the keyswitch.
What does Curtis 1226 emer rev hpd mean?
If the Curtis Controller displays 'Emer Rev HPD', it means the throttle, direction, and interlock inputs were not returned to neutral after an emergency reverse operation. If the EMR Dir Interlock parameter’s value is On, clear the interlock, throttle, and direction inputs. Otherwise, clear the throttle and direction inputs.
What does Curtis Controller AUX 1 Driver Shutdown mean?
If the Curtis Controller displays 'AUX 1 Driver Shutdown', it means the driver is open or shorted, the controller’s or contactor coil’s connector pins are dirty, or there are bad connector crimps or faulty wiring. Repair the wiring and connections, then cycle the keyswitch.
What does Curtis Controller Driver 1 Shutdown mean?
If the Curtis Controller displays 'Driver 1 Shutdown', it could indicate that the coil is open or shorted, the connector pins for the controller or contactor coil are dirty, there are bad connector crimps or faulty wiring, or there is driver overcurrent. Address the possible causes, then cycle the keyswitch.
What causes severe B+ undervoltage in a Curtis 1226 and how to fix it?
A severe B+ undervoltage in your Curtis Controller can be caused by several factors: a system other than the controller draining the battery, high battery resistance, a disconnected battery, a blown B+ fuse, the main contactor failing to close, or incorrectly configured undervoltage parameters. Address these possible causes and then cycle the keyswitch.
What does Curtis 1226 Controller BB Wiring Fault mean?
A 'BB Wiring Fault' on the Curtis Controller indicates bad crimps or faulty wiring for the emergency reverse normally open switch. Fix the wiring, then cycle the keyswitch.
What to do if Curtis 1226 displays severe overtemp?
If your Curtis Controller is showing a severe overtemp error, it means the controller is operating in an extremely hot environment. Decrease the heatsink temperature to below 85°C, then cycle the keyswitch.
