To guarantee a correct door travel:
- the rail has to be screwed to the door
in the matching height,
- the support has to be aligned parallel
to the door.
The matching height of the rail depends on the
toothed rack.

both directions.
The door operator is cut-out in the end positions
"door open" and "door closed" without mechanical
end switches but with electronic microprocessor
control. An incremental transmitter that is integrated
in the operator is activated by a magnet and registers
the actual door position.

Caution!
Before operating the hand transmitter
please make sure that there are neither
persons nor objects in the operating
range of the door.
• Connect both transmitters with the enclosed learning
plug.
Advice!

of the hand transmitter can be used
identically.

transmitter while still holding the button on the
master transmitter.
After 1 - 2 sec. the LED on the new transmitter glows
permanently.
The programming is finished.
The new hand transmitter has now taken over the
coding of the master transmitter.
• Remove the learning plug.
Advice!
For multi-channel hand transmitters
the coding process has to be carried
out for every single button separately.

• Insert the learning plug into the hand transmitter.
• Short-circuit one of the two outer pins of the
learning plug with the centre lead (e.g. by means
of a screwdriver).
• Actuate the desired button on the hand transmitter.
The integrated random programming determines a
new coding.
The LED is flashing quickly.
As soon as the LED on the hand transmitter glows
permanently, you can release the button on the
transmitter and remove the learning plug.
Advice!
After a new coding of the hand
transmitter the operator for the sliding
gate has to be re-programmed as well
to the new coding as the old coding
has gone lost irrevocably.
For multi-channel hand transmitters the
coding process has to be carried out for
every single button separately.

9.1 General notes on programming
The programming is carried out with the buttons +, -,
and P.
If none of the buttons is actuated within 120 sec. in
programming mode, the control unit changes back to
the operating mode.
An error message is displayed accordingly.
9.1.1 Programming levels
The programming of the operator is divided in two
areas:
1. Programming of the basic level:
The basic functions of the operator are programmed
in this level. This programming process is carried out
consecutively and it is compulsory.
To come to the programming of the basic level,
button P must be pressed longer than 2 sec. but less
than 10 sec..
LED 2 is flashing.
2. Programming of the extended
operator functions:
The programming of the extended operator functions
may only be carried out by specialist personnel.
As soon as the button P is pressed longer than 10 sec.,
the control unit changes to the programming of the
extended operator functions.
LED 2 is then flashing quickly.
Advice:
In the extended operator functions
important factory settings can be
changed.

9.1.2 Reference point
The following is displayed:
In operating mode
The LED shortly lights up when the reference
point is passed
In programming mode
Advice:
The control unit can only be
programmed when the reference point
has been passed electrically.
Therefore the door has to be travelled
1x to the end position OPEN and 1x to
the end position CLOSED before first
programming.
The operator is between the reference point
and the end position OPEN.
The operator is between the reference point
and the end position CLOSED.
9.1.3 Setting the door positions
The programming of the "end position OPEN" and
"end position CLOSED" can be carried out in two ways:
1. Coarse adjustment by permanently holding
a button
The setting is carried out when button + or - is pressed
permanently.
The door travels correspondingly to the OPEN or
CLOSED position.
2. Fine adjustment by a short button impulse
The setting is carried out by a short button impulse
on button + or -. The door does not move during this
procedure.
Every time the button is pressed the end position is
shifted by 4 mm to the respective direction.
To test the end position, the door has to be traveled
over the reference point to the OPEN position or to the
CLOSED position.
During the button impulse the LED 7
is flashing quickly.
Advice:
The control unit travels without
press-and-release.
