ADJUSTMENT STEP 1
Program the Travel Limits
Travel limits regulate the points at which the door will
stop when moving up or down. Follow the steps below
to set the limits.
To program the travel limits:
1. Press and hold the black button until the yellow indicator
light starts flashing slowly then release.
2. Push and hold the black button until the door reaches
the desired UP (open) position (Figure 2). Adjust the
position of the door by using the black and purple
buttons. Black moves the door UP (open) and purple
moves the door DOWN (close).
Check to be sure the door opens high enough for your
vehicle.
NOTE: Refer to previous page for correct door position for
one-piece door.
3. Push the remote control or door control (Figure 3). This
sets the UP (open) limit and begins closing the door.
Immediately press either the black or purple button; the
door will stop.
Adjust the desired DOWN (close) limit position using the
black and purple buttons (Figure 4). Check to be sure
the door is fully closed without applying excessive
pressure on the rail (rail should not bow upwards and
the belt should not sag or droop below the rail). Push
the remote control or door control (Figure 3). This sets
the DOWN (close) limit and begins opening the door.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
• Incorrect adjustment of garage door travel limits will
interfere with proper operation of safety reversal system.
• After ANY adjustments are made, the safety reversal system
MUST be tested. Door MUST reverse on contact with 1-1/2"
high (3.8 cm) object (or 2x4 laid flat) on floor.
