E370
Interlock switch sensed open for 2 minutes
This code typically points to
- Loss of 24VAC seen by the control on the DS/interlock path
- Open interlock / door / safety switch circuit
Next checks to confirm
- Verify continuity of the interlock/DS circuit
- Restore continuous 24VAC to the DS terminal
Escalation
Control terminates all services and waits for interlock switch to close
Reset behavior
Alarm clears when 24VAC is continuously sensed on DS for at least 10 seconds or on power reset.
