GATE FITTING
For steel gates, fixings should be welded on or through bolted. When
through bolting the gate, use large washers or a plate on the other side.
The drive mechanism exerts an extremely high force on this joint.
Fixings must be through bolted for wooden gates. Wood deflects under
load and the bolt will become loose. Due to movement caused by
repeated loading, the wood deflects more and more until the gate no
longer closes correctly and has to be repaired.
The arm should not be mounted while fully extended (see Fig. 4). The
drive is self-locking. The unit should be mounted with an offset of about
90 degrees. If the arm's point of contact is further to the outside, it will
require less room at the side but it will be harder to drive. Mount the
drive provisionally (e.g. with finger-tight thumb-screws), and check the
mounting position by opening the gate manually.
LIMIT SWITCH
The internal limit switch of the ART turns the drive off when the preset
point is reached. Remove the cover of the drive unit, and turn the cam
until the desired end point has been reached. Check which cam has
which function (e.g. top cam opens gate).
Switch the drive on, let it run until the desired point is reached and
interrupt the current with the aid of the main switch. Now turn the limit-
switch dial to the microswitch trigger point.
Most control units have a time function. This should always be set 3 - 5
seconds more than the time actually required. The preliminary setting
should be made for more than this to allow a safety margin. After the
necessary adjustments to the system have been made, the time can be
set more accurately. NB: The drive works more slowly under windy
conditions.
SAFETY MEASURES
THE WING GATE OPENER SHOULD ALWAYS BE OPERATED IN
CONJUNCTION WITH FLASHING LIGHTS, CONTACT STRIPS AND
PHOTOELECTRIC BARRIERS FOR ADDED SAFETY.
In any case, take care to comply with the relevant standards and
regulations.
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).
ELECTRONIC CONTROL
The control board should be the last item to be connected, i.e. mounting
the motors, laying the necessary cable and fitting light barriers or contact
strips. If installation is to be performed in a permanent location, a means of
disconnecting the equipment from the mains supply with a contact
clearance of at least 3 mm is needed (master switch).
Please note: in these instructions, relay contacts are designated NC
(normal closed) or NO (normal open).
• NC contacts are closed and open
• NO contacts are open and close
Humidity and water will destroy the control board. Always make sure
that water, humidity and condensation cannot enter the control box. It is
vitally important that all openings and cable glands are sealed so that
they are watertight.

DESCRIPTION OF JUMPER
JP1: MOTOR
OPEN: (without jumper): only for single-wing gates
(only motor 1).
CLOSED: (with jumper): only for double-wing gates
(motors 1 and 2).
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.
