If the door only operates in "hold-to-run" mode for closing, there may be a fault in the safety edge system.
Connect incoming power to terminals L1, L2, L3, and PE (Earth). Ensure correct phase rotation so the door moves in the intended direction. For 1-Phase Units: Connect to terminals L, N, and PE. Motor and Encoder Cable

Clean the door shaft and remove any burrs or rust. Ensure the keyway is clear.
Once mechanical and electrical installations are complete, you must run a final verification checklist before placing the door into daily service. Commissioning Checklist
