Position OFF: Smooth closing, to be used on doors without lock.
Position ON: More powerful closing, to be used on doors with lock, to overcome binding in the locking device (inactivated
for Inverse door).
2)
If the switch is set to ON, the LOCK RELEASE is active during the opening delay time set by the potentiometer.
For PAIR OF DOORS installations, the LOCK RELEASE works in sequence: First the primary door then the secondary door.
Note! Lock only functions when Program Selector is in OFF or EXIT.
*
After changing any system selection a new LEARN must be carried out.
With selection 'Locked without power' is the lock energized from 0 to 10 degrees at opening.
If a program selector is not used, a jumper is required from position 3 to position 11.
