The MOTOR WARM message on the Curtis Instruments Controller indicates that the field resistance is greater than the motor warm setpoint. The condition clears when the resistance is less than the setpoint.
What causes Curtis Instruments MultiMode 1243 Generation 2 Controller to display HW FAILSAFE and how to fix it?
A HW FAILSAFE error on the Curtis Instruments Controller can be caused by a noisy environment, a self-test or watchdog fault, or a controller failure. Try cycling KSI. If the problem continues, consider replacing the controller.
What does SRO mean on a Curtis Instruments MultiMode 1243 Generation 2 and how to resolve it?
If the Curtis Instruments Controller shows SRO, it may be due to an improper sequence of KSI, interlock, and direction inputs; an open interlock or direction switch circuit; a sequencing delay that is too short; a wrong SRO or throttle type selected; or a misadjusted throttle pot. Follow the proper sequence, adjust the throttle if necessary, and adjust programmable parameters if needed.
What to do if Curtis Instruments MultiMode 1243 Generation 2 Controller displays M- SHORTED?
If the Curtis Instruments Controller shows 'M- SHORTED', this could be due to an internal or external short of M- to B-, incorrect motor wiring, or controller failure. Check the wiring and cycle KSI. If the problem persists, the controller may need replacement.
What does HPD mean on a Curtis Instruments MultiMode 1243 Generation 2 Controller and how can I fix it?
If your Curtis Instruments Controller displays HPD, it could be caused by an improper sequence of KSI, interlock, and throttle inputs; a misadjusted throttle pot; a sequencing delay that is too short; or a wrong HPD or throttle type selected. Follow the correct sequence, adjust the throttle if necessary, and adjust programmable parameters as needed.
What does MOTOR HOT mean on Curtis Instruments Controller?
The MOTOR HOT message on the Curtis Instruments Controller indicates that the field resistance is greater than the motor hot setpoint. The condition clears when the resistance is less than the setpoint.
Why Curtis Instruments MultiMode 1243 Generation 2 Controller shows THERMAL CUTBACK?
A THERMAL CUTBACK error on the Curtis Instruments Controller can be triggered if the temperature is greater than 85°C or less than -25°C, there is excessive load on the vehicle, or the controller is improperly mounted. The condition clears when the heatsink temperature returns to within an acceptable range.
What does ANTI-TIEDOWN mean on Curtis Instruments MultiMode 1243 Generation 2 and how to resolve it?
The ANTI-TIEDOWN error on the Curtis Instruments Controller appears when mode switches are shorted to B+ or Mode Select 1 is “tied down” to select Mode 2 or Mode 4 permanently. Release Mode Select 1.
What does it mean when Curtis Instruments Controller displays FIELD OPEN?
If the Curtis Instruments Controller displays FIELD OPEN, it indicates an open field winding connection or an open field winding. Check the wiring and cycle KSI.
What to do if Curtis Instruments MultiMode 1243 Generation 2 shows MAIN CONT WELDED?
If the Curtis Instruments Controller displays MAIN CONT WELDED, it indicates that the main contactor is stuck closed or the main contactor driver is shorted. Check the wiring and contactor, then cycle KSI.
