Electrical Checkout
after completion of installation & wiring, and with the unit
properly powered, perform the following tests:
3a Hold Open
With power on, open the door any position and release. The door
should remain in the hold-open position within 10°. For a bypass
model to hold open, the door must be opened beyond the degree of
the door swing indicated on the label.
3b Door
If the door does not remain in the hold open position, push the on/
off switch. Open the door again. If the shaft end of the arm still does
not hold open, verify the proper voltage input at the solenoid leads.
3c Power Release
Turn the power off. The shaft end of the arm should rotate and pick
up the rest of the arm, closing the door completely. Push the on/off
switch again to restore the power.
3d Put on Closer Cover
After the electrical checkout is complete, fit the closer cover onto
the closer and insert cover screws in proper locations. Hold the
cover firmly against the mounting plate while tightening the cover
screws securely.
3e Rechecking the System
The system should be checked at regular intervals. It is
recommended that steps 3a-3c be repeated every 90 days.
