Adjusting the Open and Close Limits
The limit settings control how far the door will open and close. Set the limits so the door opens just short of any door stops, and closes at the oor
level. Out of the box, the operator is preset on its close limit and the open limit is preset for a 7-foot high door.
Use the wall station or a transmitter to test operate the door. If required, use the following steps to adjust the limits.
CAUTION
Set the open and close limits carefully. Setting the limits beyond the distance that the door can travel could cause damage to the door, the door
hardware, or operator.
Adjusting the Open Limit
a) Use the wall station or a transmitter to move the door near the desired
open limit position.
b) On the operator, press both the UP and LEARN buttons for three seconds.
The green indicator and operator’s light will ash twice then stay on.
c) If necessary, use the UP and DOWN buttons to jog the door at slow speed
to ne-tune the open limit position.
d) When the door is at the proper open limit position, press the LEARN button
to store the setting and exit setup. The green indicator and the operator’s
light will ash two times.

Automatic Door Force Setup
The operator automatically measures the door force throughout the entire
travel of the door each time the operator cycles. The following steps are all
that’s required to setup the safety reversal system.
a) Be sure that the trolley latch is up, and the door is connected to the
operator.
b) After limits have been set, you may begin using the operator. The
learning process will be complete after the fourth cycle.
CAUTION
Do not cycle the operator full travel without the door connected. The
automatic door force setting will adjust to the unloaded condition and may
trip the safety system when the door is reconnected.
