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 CURRENT SHUNT FAULT?
If the Curtis Instruments Controller displays a CURRENT SHUNT FAULT, it could be due to abnormal vehicle operation causing high current spikes, a current sensor out of range, or a controller failure. Try cycling KSI. If the problem persists, the controller may need to be replaced.
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.
What does it mean when Curtis Instruments Controller displays THROTTLE WIPER LO?
The THROTTLE WIPER LO error on a Curtis Instruments Controller suggests that the throttle pot wire is open or shorted to B+, the wrong throttle type is selected, or the throttle pot is defective. The condition clears when the Throttle Wiper Low input returns to a valid range.
Why Curtis Instruments MultiMode 1243 Generation 2 Controller displays FIELD SHORT and how to resolve it?
A FIELD SHORT error on the Curtis Instruments Controller can occur due to a shorted main contactor coil, a field winding shorted to B+ or B-, or a field resistance that is too low. Check the contactor coil and field winding, then cycle KSI.
What does it mean when Curtis Instruments MultiMode 1243 Generation 2 shows THROTTLE WIPER HI?
The THROTTLE WIPER HI error on a Curtis Instruments Controller indicates that the throttle input wire is open or shorted to B+, the throttle pot is defective, or the wrong throttle type is selected. The condition clears when the Throttle Wiper High input returns to a valid range.
What does EMR REV WIRING mean on Curtis Instruments MultiMode 1243 Generation 2 Controller and how to fix it?
The EMR REV WIRING error on a Curtis Instruments Controller indicates that the emergency reverse wire or check wire is open. Re-apply emergency reverse or cycle interlock.
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 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 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.
