TEST

• With the door fully open, place a 40 mm high object laid

flat on the floor, centred under the garage door.

• Operate the door in the down direction. The door must

reverse on striking the obstacle.

ADJUST

• If the door stops on the obstacle, it is not travelling far

enough in the down direction. Complete Adjustment
Step 1, Programming the Limits and Forces to increase
travel distance in the down direction.

NOTE: Make sure the limit adjustments do not
force the door arm beyond a vertical position.
Refer Figure 3, page 14.

• Repeat the test.

• When the door reverses on the 40 mm high object laid

flat, remove the obstacle and run the opener through 3
or 4 complete travel cycles to test adjustment.

• If the opener continues to fail the Safety Reverse Test,

call for a qualified door technician.

• Safety reversal system MUST be tested every month.

• After ANY adjustments are made, the safety reversal system
MUST be tested. Door MUST reverse on contact with 40 mm
obstacle on the floor.

IMPORTANT SAFETY CHECK:

Test the Safety Reverse System once a month and after:

• Each adjustment of door arm length, limits, or force
controls.

• Any repair to or adjustment of the garage door
(including springs and hardware).

• Any repair or changes to the garage floor.

• Any repair or adjustment of the opener.

INSTALLING YOUR WIRELESS E138M WIRELESS WALL BUTTON

NOTE: This accessory must be used for all installations
where the closing force as measured on the bottom of the
door is over 400 N (40 kgf).

SPECIAL NOTE: Merlin strongly recommends that The

Protector SystemTMbe installed on all garage door openers.

IR BEAMS: By installing IR Beams, an open door is prevented
from closing if a person or object is located in the beam area. If
the door is already closing, it will return to the open position. A
closed door is not prevented from opening.

If the Protector SystemTMis installed and needs to be removed,
the opener will need to be reprogrammed (refer toDisabling the
Protector System, Page 20).

Assembly Process:

The IR Beams are supplied preassembled, complete with two
sensors, wiring and wall brackets. (fig1 & fig2)

Install the mounting brackets and sensors to either side of the
inside of the garage door, and at a height of no greater than 100
mm off the garage floor.

The brackets are designed to be used for Wall or Floor fixing, with
a variety of hole combinations to achieve the desired results.

Drill the required holes and install the brackets with wall plugs and
screws provided. Ensure they do not obstruct the door
movement.

Wiring Process:

Align the Sensors to face each other and tighten if necessary. The
wiring should exit from the bottom of the housing to maintain the
correct IP rating and continued operation.

One sensor is a Sending Eye , the other is a Receiving Eye. Try
to avoid positioning these in direct sunlight as this may interfere
with the operation of the beams.

Run both sets of wire back to the power head CONTROL PANEL.
Ensure the wire is well supported and does not interfere or get
damaged by movement of the door panels or spring hardware.

To prevent entrapment, install The Protector

System™ no higher than 100 mm above the floor.
Disconnect power to the garage door opener

before installing The Protector System™.

Figure 1

Figure 2

Remove Power from the Unit:

At the Power head end, cut the wires to the correct length and
strip each back around 10 mm.

Twist both White wires together and install into “quick release”
terminal 2 (white) (fig 3)

Twist both Black/White wires together and install into “quick
release” Terminal 3 (Grey) (fig 3)

(The sensors are a 2 wired system connected in a parallel
configuration).

Reinstall Power to the Unit:

When aligned correctly the Red LED on each sensor will remain

“ON constantly”.

If incorrectly aligned both LEDs will “flash”.

Correct the alignment if necessary.

The opener must now be “Enabled”, proceed to “Enabling the
Protector System”.

TROUBLE SHOOTING

1. Opener doesn't operate from either door control or
remote:

• Does the opener have electric or battery power? Plug

lamp into outlet. If it doesn't light, check the fuse box or
the circuit breaker. (Some outlets are controlled by a
wall switch.)

• Have you disengaged all door locks? Review installation

instruction warnings on page 1.

• Is there a build-up of ice or snow under door? The door

may be frozen to ground. Remove any obstruction.

• The garage door spring may be broken. Have it

replaced.

• Check battery LED for status, refer page 16.

2. Door operates from door control but not from
remote:

• Replace batteries in the remote if necessary.

• If you have two or more remotes and only one operates,

review Program Your Opener, Remote and Keyless
Entry pages 21 and 22.

• Is the Locked mode displayed on the LCD? The opener

is in lock mode. Push and hold the Lock button for 2
seconds.

3. Remote has short range:

• Check the battery in the remote is fully charged.

• Change the location of the remote control on the car.

• A metal garage door, foil-backed insulation or metal

siding will reduce the transmission range.

4. Door reverses for no apparent reason and opener
light flashes 10 times after reversing:

Check The Protector System™ (if you have installed this
accessory). If the light is flashing, correct alignment.

5. The garage door opens and closes by itself:

Make sure remote push button is not stuck "on".

6. Door stops but doesn't close completely:

Repeat Setting the Limits, refer page 17.
Repeat safety reverse test after any adjustment of door
arm length, close force or down limit.

7. Door opens but won't close:

• Check The Protector System™ (if you have installed this

accessory). If the light on the Beams are flashing,
correct the alignment.

• If opener light does not flash and it is a new installation,

repeat Setting the Limit and Force page 17.
Repeat the safety reverse test after the adjustment is
complete.

8. Opener lights do not turn on:

Unit may be operating on battery power.

• Check battery status LED, refer page 16.

• Replace light bulb (230 V/40 W maximum).

9. Opener strains:

Door may be unbalanced or springs are broken. Close
door and use manual release rope and handle to
disconnect trolley. Open and close door manually. A
properly balanced door will stay in any point of travel
while being supported entirely by its springs. If it does
not, call for professional garage door service to correct
the problem.

10. Opener hums briefly, then won't work:

• Garage door springs are broken. SEE ABOVE.
