What does Wiring Fault mean on Curtis Controller?
- TTimothy SmithAug 19, 2025
A Wiring Fault on a Curtis Controller means that HPD Lockout has existed for more than 10 seconds. To resolve this, cycle KSI.
What does Wiring Fault mean on Curtis Controller?
A Wiring Fault on a Curtis Controller means that HPD Lockout has existed for more than 10 seconds. To resolve this, cycle KSI.
What to do if Curtis 1205M shows a throttle fault?
If the Curtis Controller shows a throttle fault, it could be due to several reasons: * The throttle input wire may be open or shorted. * The throttle itself might be defective. * The wrong throttle type may have been selected. To resolve this, ensure the throttle input signal is within allowable limits.
How to fix over temperature on Curtis 1205M Controller?
If your Curtis Controller is overheating, it's likely because the heatsink temperature has exceeded the Temperature Cutoff threshold (110°C). To resolve this, ensure the heatsink temperature drops to 100°C or below.
Why is my Curtis 1205M Controller showing Under Voltage Cutback?
The Curtis Controller might show an Under Voltage Cutback for these reasons: * The battery voltage is at or below the programmed Undervoltage Cutback threshold. * There's corrosion on the battery terminal. * There's a loose connection on the battery or controller. To fix this, ensure the battery voltage rises above the Under Voltage Cutback threshold.
What causes thermal cutback in Curtis 1205M Controller?
Thermal Cutback in a Curtis Controller can occur due to: 1. Temperature reaching the Temp Cutback setpoint or dropping to -10°C or below. 2. Excessive load on the motor or controller. 3. Improper mounting of the controller. 4. Operation in extreme environments. 5. Damage to the controller thermistor. During overtemperature, current is reduced. During undertemperature, current is reduced to 50%.
What to do if Curtis 1205M has a Main Weld Fault?
If the Curtis Controller indicates a Main Weld Fault, it could be due to: * A welded main contactor. * The main contactor being controlled externally while the main driver function is active. To resolve this: 1. Replace the main contactor. 2. Correct the parameter Rev Input / Main Driver.
What causes over voltage in Curtis 1205M?
Over voltage in a Curtis Controller can be caused by: * Battery voltage exceeding the factory-set Over Voltage Cutoff threshold. * Operating the controller with a charger attached. To resolve this, ensure the battery voltage falls below (Over Voltage Cutoff - Over Voltage Hysteresis).
What to do if Curtis 1205M Controller shows HPD error?
If the Curtis Controller displays an HPD error, it's likely due to: * Applying throttle input greater than 20% when KSI is turned on. * Applying throttle input greater than 20% after clearing a throttle fault. To fix this, release the throttle.
How to resolve EEPROM Fault on Curtis 1205M?
An EEPROM Fault on a Curtis Controller can occur if: * EEPROM data is lost or damaged. * There's an EEPROM checksum error. To resolve this, modify any programmable parameter using a programmer.
What causes MOSFET Short Fault in Curtis Controller?
A MOSFET Short Fault in a Curtis Controller is typically caused by a shorted MOSFET. To resolve this, cycle the KSI.
