Timer to close
Description of the operation:
The garage door opener closes the garage door automatically from
the fully open position after a pre-programmed period of time.
For this, the Liftmaster safety light barrier must be connected to the
garage door opener according to EN60335-2-95.
Activating:
1. Press the P button and the MINUS (-) button simultaneously for about
3 seconds.
2. When you release the buttons, the LED next to the S button turns on
and the operator lighting flashes twice as confirmation that the garage
door opener is in programming mode.
3. Each time you press the PLUS (+) button the time period increases
by 10 seconds. Maximum 180 seconds are possible (= pressing 18
times).
4. Each time you press the MINUS (-) button the time period reduces
again by 10 seconds (up to a minimum of 10 seconds).
5. To save the desired time period, press the P button. To confirm the
programming, the operator lighting flashes once.
Disabling:
1. Press the P button and the MINUS (-) button simultaneously for about
3 seconds.
2. The operator lighting will flash twice to confirm that the garage door
opener is in the disable mode.
3. Press P button once.
4. The operator lighting flashes once to confirm that the automatic clos-
ing function has been disabled.
Information:
• Automatic closing only works from the fully open position (garage door
must have reached the end position OPEN).
• If the light barrier is interrupted during closing, the garage door goes
back to the fully open position and remains there until the obstacle
has been removed and after the programmed time period has elapsed
again.
• Once the garage door opener is in programming mode, the next but-
ton press must be carried out within 30 seconds, or else the program-
ming mode is cancelled. In this case, the operator lighting flashes five
times.
• If the time period needs to be subsequently changed, for example,
from 60 to 80 seconds the PLUS (+) button must be pressed eight
times in the programming mode, as every new programming starts at
0 seconds.
Troubleshooting:
The garage door opener does not operate without the light barrier.
No error! Connecting the light barrier once is absolutely necessary.
Cycle counter
The garage door opener can display the number of cycles (OPEN/
CLOSE = 1).
1. Disconnect garage door opener from power supply
2. Press and hold the P and S buttons
3. Connect the garage door opener again while the buttons are still
pressed
4. After all three LEDs have flashed once and the operator lighting is
switched on, the LED near the S button starts flashing after approxi-
mately 5 seconds (once every 1000 cycles). Release the buttons.

Cleaning and maintenance

Before any maintenance, cleaning and related
maintenance work, the mains supply plug should be
pulled out. Danger from electric shock!
Maintenance of the door opener
A proper installation ensures the optimum performance of the door
opener with minimum maintenance. An additional lubrication is not
required. Gross dirt accumulation in the guide rail may impair the
function and must be removed.
22

Cleaning

Clean the drive head, wall switch and handheld transmitter with a soft,
dry cloth..
Do not use liquids.
23

Maintenance

Check the system often, especially cables, springs and
fasteners, for signs of wear, damage or lack of balance.
Do not use if repair or adjustment work must be performed,
because an error in the system or an incorrectly balanced
door may cause injury. Repairs to electrical equipment and gates may be
carried out only by an authorized specialist / expert. In any case, please
do not ever carry out repairs yourselves because this could result in
serious injury or death.
Once a month:
• Check automatic safety reverse again and reset if necessary.
• Operate door manually. If the door is unbalanced or stuck, please
contact the service centre.
• Check for complete opening and closing of the door.
Where appropriate, readjust limit switches and / or power.
Twice a year:
• Check the belt tension. For this, first disconnect the carriage from the
drive. If necessary, adjust belt tension.
Once a year (at the door):
• Lubricate door roller, bearings and joints. An additional lubrication of
the door opener is not required.
Do not grease the door rails!
Limit switch adjustment and force regulation:
These settings must be checked and undertaken properly during the
installation of the opener. Due to weathering, minor changes can occur
during operation of the opener that need to be addressed by a new
setting.
This can particularly happen in the first year of operation.
Follow the instructions for setting limit switches and traction (see 9.1)
carefully and re-check the automatic safety reverse after each
resetting.
