Click steps to track your progress.
1. Cycle power to the soft starter; wait a full 60 seconds before reapplying power for a complete system reset.
2. Remove all external control wiring (digital inputs, analog inputs, communication cables) and power cycle; reintroduce wiring one by one to isolate potential external interference.
3. Perform a factory reset via the soft starter keypad (e.g., setting P0-01 to 'Reset') to clear any potentially corrupted parameters or states.
4. If accessible, check for proper grounding of the soft starter enclosure and ensure EMI filters are correctly installed and wired on the incoming line.
5. Record the specific trap code displayed (if any) and contact manufacturer support with the code and soft starter serial number.
