Then, check the electrical power switch to make sure the unit is receiving power. Also, verify that the activation unit is functioning by jumping the activation input.

  If the motor of your Assa Abloy Door Opening System starts but the door doesn't open, first check if the mechanical lock is locked and unlock it. Next, inspect for any obstructions beneath the door and remove them. Also, examine the electric strike plate for binding issues and select the toggle dip switch for lock release. Adjust the strike. Finally, if the arm system has come loose, turn the potentiometer SPTE until the door-stop hits the stop-block, put the door in the required open position, tighten the arm system, and turn SPTE to 0°.
