Possible Causes

Service door or panel not fully closed, Faulty door safety switch, Broken wiring in safety loop, Bypassed or miswired safety contacts

How to Fix / Troubleshooting

Safety first: Never bypass safety switches for normal operation. They protect against contact with moving and live parts.

  • Close all panels: Ensure all access doors and service panels on the Pramac enclosure are fully closed and latched.
  • Inspect door switches: Locate the magnetic or mechanical door switches. Check alignment between switch and actuator. Adjust mounting if necessary.
  • Check continuity: With power off, test continuity through the safety loop from the controller terminals. Repair or replace any open switches or damaged wiring.
  • Clear alarm: After restoring the safety circuit, clear E17 and test start.
