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 two 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 re-
motes 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 turn the red handle down. Then open the door by
hand. Open close door without pulling the cable!
LOCK: With the next upward or downward movement, it is automatically
locked again.
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 lo-
cated 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.

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.
11.1

Cleaning

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

Maintenance

11.2
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, be-
cause an error in the system or an incorrectly balanced door may cause
injury.
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 chain tension. For this, first disconnect the carriage from
the drive. If necessary, adjust chain tension.
• Lightly lubricate the guide rail with standard grease (lubrication).
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 in-
stallation of the opener. Due to weathering, minor changes can occur
during operation of the opener that need to be addressed by a new set-
ting. 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.
