4-8.4.9 Adjustments
4-8.4.9.1 Adjusting Motor Limit Switches
Tools Required
Black plastic key provided with awning or 4mm Allen Wrench
PROCEDURE
The limit switches are adjusted at the factory, prior to shipment, such that the awning motor stops at
the EXACT moment the awning box closes. Likewise, the awning motor is set to stop at the EXACT
moment that, while opening, the elbowing arms “click” into an outward locked position. Occasionally,
after shipment and installation, the motor rotational limits “creep” out of adjustment. It is always wise
to check the motor limits after installation to assure that the awning is opening and closing correctly.
Additionally, over a period of time the awning fabric can stretch, causing the need for simple motor
limit adjustments.
VERY IMPORTANT: Extreme care must be taken when setting the “IN” limits of the motor,
such that the motor turns off EXACTLY the same time the box closes. Otherwise, the motor
will continue to run, as it has not reached its limit. This condition, if not corrected, will
substantially reduce motor life. Turn the awning switch OFF.
If adjustments are required, please follow these instructions:
1. The BMO (Manual Override) motor has limit settings for both the OUT direction (projection)
and the IN direction (retraction).
2. Limit switches are adjusted using the black plastic key (provided) or a 4mm Allen Wrench.
3. Open the awning a few feet and locate the awning motor, installed standard at the right end
of the awning (front end). It is a cylindrical motor mounted inside the awning roller tube. The
limit switches are mounted inside the black casing at the exposed end of the motor. Notice at
the limit switches a BLACK arrow and a RED arrow, both with a (+) plus and (-) sign. The
actual limit switch is the recessed hole next to the corresponding arrow.
4. The IN limit is the BLACK arrow. To make the awning close MORE, first turn the main awning
wall switch or Wind Sensor switch to the IN (retract) position. At the motor, insert the tool and
turn the switch next to the BLACK arrow in the direction of the (+) sign. ¼ turn represents
approximately 1” of the awning movement. This action will create a tighter fit as the awning
box closes. To make it close LESS, turn in the direction of the (-) sign. See
Fig. 1 .
NOTE: If the awning motor is installed on the LEFT end of the awning, the actions of the red
and black arrows will be reversed.)
