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
INFRARED SENSOR (OPTIONAL)
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
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
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!

DESCRIPTION OF DIP SWITCHES

• Automatic closing or default
• Dead man's operating mode
• Electric lock function
• Response of light barrier

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
