FLASHING LAMP 18 a
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. Generally
speaking, it is installed at the highest possible point (on a pillar).
Cross-sectional area: 0.75mm

3-pole voltage: 230 Volt/AC.
NFRARED SENSOR
The IR Sensor (fig. 16-19) 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
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).
Cable connections as per wiring plan.

INSTALLATION OF KEY-OPERATED SWITCH
Cable connections as per wiring plan. Terminal 15/17 respectively 18.
ELECTRICAL LOCK (OPTIONAL)
An electrical lock can be connected to terminals 19 - 20. Output voltage:
12 V AC. See 'DIP Switch Settings' section too!
Please note: In the case of a single-wing gate, the wing delay
mechanism (potentiometer) has to be activated.
DESCRIPTION OF DIP SWITCHES
The DIP switches control the general functions of the installation:
• Automatic closing or default
• Dead man's operating mode
• Electric lock function
• Response of light barrier

DIP switch 2 ON

DESCRIPTION OF POTENTIOMETER
• Force M1 Force M2:
Adjust the force with which the door operates for each wing separately.
The rotary potentiometer is used to make fine gate/door adjustments.
Should the force generated by the moving wing at its closing edge
exceed 400 N, additional safety features (IR sensors, contact
strips) must be fitted. Any safety features fitted must comply with
the appropriate standards (Europe: EN60335-1). See 'Safety Rules'
section too.
• PAUSE
This function is only active if DIP switch 1 is set to ON. It adjusts the
time for which the gate/door is kept open before it closes again.
Adjustable: 8-200 seconds.
• OPEN-CLOSED
Adjust the maximum running time of the wings. Set the running time to
approx. 30% and then test. Correct adjustment is obtained when the
drive continues to run (hum) against the end stop for 3-5 seconds each
time in one complete cycle. This is necessary because the required
running time is affected by external influences and it must be ensured
that the end position is reliably reached (wind, temperature, changes in
ground conditions). This is why end stops in the OPEN and CLOSE
directions are stipulated as being mandatory. Adjustable: 7-60
seconds.
• WING DELAY
Controls the wing delay in the case of installations with overlapping
wings. Wing M1 opens first and closes last. A delay must always be set
in order to make sure that no one can trap themselves between two
closing wings. Adjustable: 0-35 seconds
