7.4. Connection of the antenna / radio board

A wire aerial is connected to the lower terminal of the SK1 (Terminal 2).
The length of the wire aerial depends on the frequency and should hang
to the side of the control board.
As an alternative to wire aerial, the cable core of a rod antenna can be
connected to terminal 2. We recommend mounting the aerial rod as high
as possible in order to avoid frequency disruptions caused by the gate.
The receiving frequency depends on the 15-pin radio plate. The receiving
frequency of 868, 3 MHz is currently included as standard equipment.
Optionally, it is possible to order other frequencies such as 433, 92 MHz,
40,685 MHz and 27,015 MHz.

7.5. Push button inputs A-D

For the functions impulse, open, close and partial opening, command de-
vices with potential-free closing contacts can be connected to the SL6
plug connector.
As soon as a running direction is blocked by a safety input LS, SE1 or SE2
and the emergency function is activated in the menu, the input for this
running direction switches to the emergency function operating mode. By
actuating the command transmitter three times, you can move the motor
in the desired running direction in emergency function operation despite
the triggered safety. You can activate this emergency function in menu
option 27.
Using the menus for inputs A-D, you can set an input for connecting the
OPEN limit switch for gate type DIN left (CLOSE limit switch for gate type
DIN right). The connection for the reference switch, SL5, is then automati-
cally the limit switch CLOSED for gate type DIN-left (limit switch OPEN for
gate type DIN-right).

CAUTION!
External safety devices must be approved for personal protection and are not
tested by the control unit! The correct function must be checked at least every
6 months.
