If your Curtis Controller shows an Overcurrent Shutdown, it indicates that the phase current exceeded the current measurement limit. This can be caused by: 1. An external short in the phase U, V, or W motor connections. 2. Mis-tuned motor parameters. 3. A defective controller. 4. Speed encoder noise problems. To clear this, cycle KSI (Key Switch Input).
What to do if my Curtis 1232E displays a Current Sensor Fault Shutdown?
If your Curtis Controller displays a Current Sensor Fault Shutdown, it means the controller's current sensors have an invalid offset reading. This can occur due to: 1. Leakage to the vehicle frame from phase U, V, or W (short in motor stator). 2. A defective controller. To clear the fault, cycle KSI.
Why does my Curtis Controller show a Precharge Failed Shutdown?
A Precharge Failed Shutdown on your Curtis Controller indicates that the precharge process failed to charge the capacitor bank to the KSI voltage. This can be due to: 1. Refer to the Monitor menu, Battery: Capacitor Voltage for more details. 2. An external load on the capacitor bank (B+ connection terminal) preventing charging. To resolve this, cycle the Interlock input or use the VCL function Precharge().
How to troubleshoot a Precharge Failed error on a Curtis 1232E Controller?
Precharge failure in a Curtis Controller means the precharge has failed to charge the capacitor bank to the KSI voltage. This can be caused by an external load on the capacitor bank (B+ connection terminal) preventing charging. To clear it, cycle the Interlock input or use the VCL function Enable_Precharge().
What to do if Curtis 1232E shows Severe Undertemp Shutdown?
If your Curtis Controller displays a Severe Undertemp Shutdown, it means the heatsink temperature is below -40°C. This can happen because: 1. Refer to the Monitor menu, Controller: Temperature for more details. 2. The controller is operating in an extreme environment. To clear this, bring the heatsink temperature above -40°C, and then cycle the interlock or KSI.
What to do if my Curtis 1232E shows a severe overtemp?
If the Curtis Controller's heatsink temperature rises above +95°C, it triggers a severe overtemp condition. This could be due to the controller operating in an extreme environment, excessive vehicle load, or improper mounting. To resolve this, reduce the heatsink temperature below +95°C and cycle the interlock or KSI.
How to fix a Curtis 1232E Controller overcurrent issue?
Controller overcurrent can occur if the phase current exceeds the current measurement limit. This can be caused by an external short in the phase U, V, or W motor connections, mis-tuned motor parameters, a defective controller, or speed encoder noise problems. To clear this, cycle the KSI.
Why does my Curtis Controller show a severe B+ undervoltage?
Severe B+ undervoltage in a Curtis Controller happens when the capacitor bank voltage drops below the Severe Undervoltage limit with the FET bridge enabled. This can be caused by misadjusted battery parameters, non-controller system drain on the battery, high battery resistance, the battery disconnecting during driving, or a blown B+ fuse. To resolve, bring the capacitor voltage above the Severe Undervoltage limit.
What causes a Curtis 1232E severe undertemp error?
If the Curtis Controller's heatsink temperature falls below -40°C, it triggers a severe undertemp condition, often due to operating in an extreme environment. To resolve this, bring the heatsink temperature above -40°C and cycle the interlock or KSI.
Why is my Curtis 1232E showing a severe KSI undervoltage?
Severe KSI undervoltage in a Curtis Controller occurs when the KSI voltage drops below the Brownout Voltage for 2 seconds. This can be due to a non-controller system drain on the battery/KSI circuit wiring, KSI disconnecting while driving, or a blown KSI fuse. To fix this, bring the KSI voltage above the Brownout Voltage.
