Attention
Remove the mains plug before carrying out any
work on the drive!
Instruct all persons using the door system with
regard to its correct and safe operation:
Whilst the drive is operating, the opening and
closing processes must be monitored.
Keep hand transmitters away from children.
No people or objects must be located within the
swivel range of the door.

Operational sequence

The garage door drive can be operated by pulse generators
such as hand transmitter, keyswitch etc.. Only short pulses
are required.
First pulse generation:
Drive starts and moves door to the set UP or DOWN end posi-
tion.
Pulse generation
During movement: Door stops.
Repeated pulse:
Door continues the run in the opposite direction.

Internal safety device

If the door encounters an obstacle whilst closing, the drive
stops and clears the obstacle again by opening as far as the
top end position.
During the last 2 seconds of the closing movement, the door
is opened just a crack in order to allow the obstacle to be
cleared, whilst still obstructing the view of the garage.
If the door encounters an obstacle whilst opening, the drive
stops immediately. The door can be closed again by generat-
ing another pulse.

External safety devices

Note
See connection plan, figure 13.
Personal door contact (STOP A)
If the personal door is open, the drive will stop immediately or
will be prevented from starting.
Light barrier (STOP B)
An interruption in the light barrier while the door is closing will
result in the drive stopping and a reversal of direction. An in-
terruption during opening has no effect.

Quick-acting release

When performing settings, and in the event of a power failure
or fault, the door can be released from the drive using the pull
button on the running slide block, and operated by hand.
If the door is to be manually operated for a prolonged period
of time, then the retention pin provided must be inserted ac-
cordingly (see Figure 12). The door lock, shut down for opera-
tion with the drive, must be remounted, as otherwise the door
will not be locked in the closed position.
To resume operation with drive, the retention pin is returned
to the park position (a) and the door lock de-commissioned.

Operating Instructions

After pulse generation the door is automatically locked with
the door drive again.

Lighting

The lighting switches on automatically after the start pulse has
been generated and switches off again after a set time (fac-
tory setting approx. 90 seconds).
A second button on the hand transmitter (optional) can be
programmed to illuminate for 4 minutes (Figure 16). When the
hand transmitter button is activated, the light switches on in-
dependently of the motor and switches off again after 4 min-
utes.
Changing the incandescent lamp:
Remove the mains plug and open the lamp cover with a
screwdriver for cross-head screws size 2 x 100. Replace the
incandescent lamp (230 V, 40 W, E27 fixing) and screw the
lamp cover on again.
Indicator lamp
If an indicator lamp for indicating the opening and closing se-
quences is installed, this will flash together with the lamp in
the drive as soon as a start impulse is given. The drive starts
after a delay in accordance with the set warning time (see
menu step 7).
Hand transmitter
Programming further hand transmitters:
See menu steps 1 and 2 (Figures 15 and 16).
Changing the battery: Slide the battery compartment cover off
the hand transmitter. Remove the battery. Insert new battery.
Ensure correct polarity!
Slide the cover on again.
Used batteries should be disposed of as special waste!!

Maintenance/Inspection

Monitoring the power limitation
The drive control has a 2-processor safety system for monitor-
ing the power limitation.
The integrated power cutoff is automatically tested in each
end position.
The door system must be checked before commissioning and
at least once a year. Please ensure that the power limitation
device (Figure 21) is also checked.
The lift power can be adjusted in menu step 5, and the de-
scent power in menu step 6.
BOM 520/820 Operating Instructions
Caution
For your safety we recommend that you have
the door system checked by an expert before
first commissioning and as required - but at
least once a year.
Attention
If the closing force is set too high, injuries can
result.
