Connecting The Opener; Program Opener And Test; Adjust Limits And Force; Test The Safety Reverse System - LiftMaster LM50EVFF Instrucciones De Montaje

It is recommended to undertake the assembly next to the garage side
entrance out of reach of children. Tighten both screws carefully and do
not tighten too much to avoid damaging the plastic housing. Run the bell
wire along the wall over the ceiling up to the door opener. Attach the wire
using nailing clips. Run bell wire from the top through the cable duct to
the terminal. The terminals are located in the recess next to the program-
ming switches. Connect bell wire to the terminals 1 + 2.

Connecting the opener

Connect opener in accordance with local rules and regulations to
a properly installed earthed wall socket.
NOTE:
When the opener is switched on, the operator light is also turned on
briefly.

Program opener and test

The door opener should only be used if the operator can see
the entire door area and is assured that it is free of obstacles
and the door opener is set correctly. No one may pass through
the door while it is moving. Before the first opening operation, check that
all the facilities that are not needed are turned off. Remove all
mounting aids and tools from the pivot area of the door.

Adjust limits and force

1. Open light cover.
2. Press „P" and hold it until LED3 starts flashing (1).
3. Press „+" and hold it until the door is completely open (2).
If neccessary adjust using „-".
4. Press „P" briefly, LED2 starts to glow (3).
5. Press „-" and hold it until the door is completely closed. The rail must
not bend up (4). If neccessary adjust using „+".
6. Press „P" again briefly. The drive now automatically opens the door
completely and then closes the door completely (5). During this
process the force required by the opener is set.
NOTES:
Do not interrupt the opener during this process otherwise you have to
repeat the whole procedure. In case the door pushes against the door
frame and reverses, the „closed" limit hasn't been set properly.
Repeat limit setting and make sure the rail doesn't bend whe setting the
„closed" limit.
Force adjustment:
When installing the opener the travel (distance between the Open and
Closed position) and the optimal pulling force is learned.
NOTE:
Before any modification to the force adjustment check the door for
proper functioning.
The opener is no support for a malfunctioning door. You can check
proper functioning by releasing the opener and opening and closing
the door manually.

Test the Safety Reverse System

The safety reverse system test is important. Garage door
must reverse on contact with a 50 mm obstacle laid flat
on the floor. Failure to properly adjust opener may result
in serious personal injury from a closing garage door. Repeat test
once a month and adjust as needed.
OBSTACLE TEST:
Place a 50 mm high obstacle (1) under the garage door on the floor.
Move door downwards. The door must reverse when it comes into
contact with the obstacle. If upon contact the door stops, the door does
not move down far enough. In this case repeat limit setting
(see 9.1).
If the door reverses after contact with the 50 mm high obstacle,
remove obstacles and open and close the door completely once.
The door should not go back, if it reaches the door position „Closed".
If it still reverses both limits must be reprogrammed (see 9.1).
OPENING TEST: Apply 20 kg to the middle of the door.
The door should not open.

Program another remote control

The supplied remote control is already programmed.
When purchasing additional remote controls, program the receiver
to match the additional remote control codes.
Program:
1. Press „S" for 1-2 seconds. LED1 begins to glow (for approx.
10 seconds).
2. Briefly press a button of the remote control twice.
3. LED1 goes out. The Code is programmed.
NOTE: Only one of the 4 buttons can be programmed.
The last programmed button functions.
Delete:
All programmed remote control codes will be deleted. Press „S" and
hold it until LED1 goes out (approx. 8 seconds). All programmed codes
are now erased. Reprogram each remote control you wish to use.
NOTE: Only the original remote controls from the manufacturer should
be used. Remote controls that may look very similar, but do not
originate from the manufacturer are not compatible. Such third-party
remotes create malfunctions such as automatic opening, and the
guarantee on the function and safety expires.

Operation of the door opener

Automatic opening / closing of the door:
The door opener can be operated using the following devices:
• Handheld transmitter: Press the button until the door starts to move.
• Wall switch (if this accessory is installed): Press the pushbutton until
the door starts to move.
• External key switch or wireless keypad (if this optional accessory is
installed).
Manual opening of the door (by hand):
If possible, the door must be closed completely. Weak or
defective springs can cause a rapid shutting down of the
opendoor, which can lead to property damage or serious
personal injury.
RELEASE: Briefly pull the red handle down. Then open the door by
hand. Open close door without pulling the cable!
RECONNECT:
The lockout feature prevents the trolley from reconnecting
automatically. Push the green button on the trolley. With the next
door movement the system will reconnect.
Function sequence:
When operating the door opener by radio control or wall switch:
• closes the door when it is fully open,
• opens the door when it is fully closed,
• stops the door if it opening or closing,
• the door moves in the opposite direction to the last completed move, if
it is partially open,
• drives back the door to the open door position, if it hits an obstruction
while closing,
• stops the door, if it encounters an obstacle during opening.
• Light barrier (optional): By means of the light barrier, a closing door
is lifted up or an open door is obstructed while closing, if a person
located in the door area interrupts the sensor beam.
The operator light switches on in the following cases:
1. First turning on of the door opener (short)
2. Power interruption (short)
3. With each turning on of the door opener.
The light turns off automatically after 2 1/2 minutes
