2. Ensure rail surface is clean and attach the lock template to the track so that the bolt hole is approximately 7.6 cm from the center of a door roller.

3. Drill holes as marked on the template.

4. Fasten automatic door lock to the outside of the door track with hardware provided.

5. Run bell wire up wall to door opener. Use insulated staples (optional) to secure wire in several places. Insert wire through the bottom of the door

opener.

6. Plug the connector into either plug in the door opener. A secondary door lock (841EU) can be installed on the opposite side of the door following

the instructions above.

TEST AUTOMATIC DOOR LOCK

1. With the door fully closed, the automatic door lock bolt (B) should be protruding through the track.

2. Operate the door in the open direction. The automatic door lock (A) should retract before the door begins to move.

3. Operate the door in the down direction. When the door reaches the fully closed position, the automatic door lock should move into lock position

to secure the door.

NOTE: If the automatic door lock does not function, the lock can be manually released by sliding the manual release handle (C) to the

open position.

Attach the Cable Tension Monitor (041A9264)

The cable tension monitor MUST be connected and properly installed before the garage door opener will move in the

down direction. The cable tension monitor detects ANY slack that may occur in the cables and will reverse the door, elimi-

nating service calls. Installation of the cable tension monitor is required according to EN12453.

NOTE: The cable tension monitor is shipped for left side installation. For right side installation, remove the snap-ring holding the roller in place and

reassemble it on the opposite side of the cable tension monitor.

1. Make sure the door cable is approximately 19 mm from the mounting surface. Door adjustments or shimming may be required to achieve proper

depth for the door cable.

2. Position the cable tension monitor so the roller is 5-15 cm from the drum and the roller extends 3-6 mm past the cable. Make sure cable tension

monitor is located over a wood support member and the roller is free from any obstructions.

NOTE: There must be no obstructions in the installation area that prevent the cable tension monitor from closing completely when slack is

detected.

3. Mark and drill 5 mm pilot holes for screws (pilot holes are not required for anchors).

4. Attach the cable tension monitor to the wall using the hardware provided. Make sure that the roller is on top of the cable.

5. Run bell wire to door opener. Use insulated staples to secure wire.

6. Connect bell wire to the green quick-connect terminals (10 + 11) on the door opener (polarity is not important).

NOTE: Cable must have tension through entire door travel. Make sure there is no slack in cable on opposite side of door during normal opera-

tion. If slack occurs during door travel, adjust cables as required.

When two cable tension monitors are installed, the door will not move in the down direction or will reverse if one of the monitors detects slack or is

disconnected.

TEST CABLE TENSION MONITOR

1. With the door fully closed, push on the front of the cable tension monitor. A click should be heard. If there is no click, the roller may be hitting the

jamb and not allowing the switch to detect slack in the cable. Make sure the cable tension monitor is mounted flush with the wall and the roller is

free from any obstructions.

The 1k resistor provided is for trouble shooting the CTM set up only. According to EN12453 the cable tension monitor must be installed for proper

detection of cable slackness.

If your cable tension monitor has been activated the UP and DOWN arrows will flash diagnostic code 3-5.
