Without a properly installed safety reversal

system, persons (particularly children) could be

SERIOUSLY INJURED or KILLED by a closing

door.

• NEVER learn forces or limits when door is

binding or sticking. Repair door first.

•Incorrect adjustment of the 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 40mm high (1 1/2”)

object on floor.

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:

Adjust the position of the door by using the black

and orange buttons. Black moves the door UP

(open) and orange moves the door DOWN (close).
1.

Setting the UP position:

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).

NOTE: Check to be sure the door opens high enough

for your vehicle to pass under.

3. Push the transmitter, wireless wall button or

multi-function door control (Figure 3). This sets

the UP (open) limit and begins closing the door.

NOTE: Excessive movement of the opener will cause

premature wear. See Troubleshooting section.

4. Immediately when the door begins to move

down, press and release either the black or

orange button. This will stop the door.

5.

Setting the DOWN position:

Push and hold the

orange button until the door reaches the desired

DOWN (closed) position (Figure 4).

6. Once the door is closed, check for proper

pressure on the door (you should be able to

manually push the door down 2mm). If there

appears to be too much pressure on the door,

you may toggle the door back and forth using

the black and orange buttons to reach the

desired position.

7. Push the transmitter, wireless wall button or the

multi-function door control (Figure 3). This sets

the DOWN (close) limit and should bring the

door to the open position.

• If the opener is not stopping exactly where you

would like it, repeat steps 1 through 7 and

program the limits again

.

• When the unit stops in both the desired up

(open) and down (close) positions, proceed to

Adjustment Step 2, Setting the Force.
