Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLYINJUREDor 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.
To prevent damageto vehicles, be sure fully open door
provides adequateclearance.
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.
