Setting the Gate Switch
1. Position the doors 1 1/2" (38mm) from Fully Closed.
2. Rotate the disk in the CLOSE direction until the shorting bar just touches the two leaf contacts.
3. Locate a tab on the locking ring that lines up with a notch in the contact disk.
4. Rotate the drive wheel until the doors are Fully Closed and ensure that the shorting bar has not
run past the leaf contacts.
5. Open and close the doors to verify that the gate switch shorting bar enters the leaf contacts at
1 1/2" (38mm) from Fully Closed.
Note:
Verify that the shorting bar remains between the leaf contacts in the Fully Closed Position.
Be sure that the gate switch leaf contacts do not rub on the thin portion of the plastic disk
during normal operation.
