DESCRIPTION OF JUMPER
JP1: MOTOR
OPEN: (without jumper): only for single-wing gates
(only motor 1 operating).
CLOSED: (with jumper): only for double-wing gates
(motors 1 and 2 operating).
JP2: channel 2 radio receiver
If both learning channels are put together (A-side), the
memory capacity of the radio receiver doubles in size. The
gate can then only be fully opened. The "Pedestrian" function
is no longer available. A-side: (optional) receiver channel 2 is
connected up to receiver channel 1.
B-side: (standard) the
two radio receiver
channels work
separately from one
another.

SAFETY
FLASHING LAMP (OPTIONAL)
Usage of a flashing lamp is mandatory. It serves a safety-related
purpose in that it warns persons in the vicinity of the gate/door
that the given gate/door is moving. The flashing lamp is fixed
using screws and wall plugs. The buried cable has to be run up
to connect with the lamp. Generally speaking, it is installed at
the highest possible point (on a pillar). Cross-sectional area:
0.75mm , 3-pole voltage: 230 Volt/AC.

INFRARED SENSOR

The IR Sensor provides additional safety to the gate/door
and must be used. Its point of installation depends on the
design of the given gate/door. Generally speaking, the light
barrier is fitted at around knee height, approx. 35 cm above
ground level. IR Sensors comprise of a transmitter element
and a receiver element, which must be located opposite one
another. A screwdriver can be used to open the light barrier
housing (plastic). The IR Sensor is fitted to the wall with small
screws and wall plugs. Usage of a single set of IR Sensors is
a minimum requirement; we recommend using two sets of
IR Sensors (and other safety facilities if necessary).
It is possible to connect the IR Sensor as described below.
Active when 'OPENING' (terminal 14) or active when
'CLOSING' (terminal 12). The instructions describe how to
connect a single IR Sensor and therefore uses both fuse
inputs, i.e. active in both directions. DIP switch 4 on the
control unit controls the door wing's response if the light
beam is interrupted while the gate/door is closing. An active
IR Sensor (only) stops the gate/door or an active IR Sensor
reverses the direction of the gate/door.
The transmitter element needs a 2-pole cable, the receiver
element a 4-pole one. Cable cross-sectional area: 0.5mm
more. Voltage: 12/24Volt AC/DC. Terminals (12-13-14) (22/23).
EMERGENCY STOP (OPTIONAL)
If a switch is connected, it can be used to stop or disable the
installation. This immediately interrupts movement of the
wing. Depending on the level of safety needed, the contact
can also be connected on the gate/door to the IR Sensor's
contacts. This immediately stops any wing movement.
DEAD MAN'S OPERATING MODE
In dead man's operating mode, a gate/door can be operated
without safety facilities insofar as the operator has a clear view
of it during the whole period of operation. There are 3 DIP
switches located on the upper part of the control unit. Set DIP
switch 2 to the ON position. The control unit only functions in
this case if a signal can be continuously transmitted via the
handset, key-operated switch or push-button. Any interruption in
the signal causes the gate/door to stop and the next signal sent
moves it in the opposite direction.
CONTROL LINES
It is possible to open only one gate/door or both gates/doors.
This function is also possible when using the radio remote
control. See initial setting of remote control. The test button
on the control unit always switches on both motors. If the
installation has overlapping wings, the wing delay must be
set. Wings that do not overlap may not close simultaneously -
risk of persons trapping themselves (see 'Description of
Potentiometer' section).
INSTALLATION OF KEY-OPERATED SWITCH (OPTIONAL)
Cable connections as per wiring plan.
ELECTRICAL LOCK (OPTIONAL)
An electrical lock can be connected to terminals 19 - 20. Output
voltage: 12 V AC. See 'DIP Switch Settings' section too!
