ELECTRONIC CONTROL
ELEKTRICAL INSTALLATION
The electronic control unit supplied is required for operation
of the wing gate actuator. This control unit comprises an
electronic microprocessor-control system employing the
latest technology. It may be used for the connection of 1 or 2
motors and offers all connection possibilities and functions
necessary for safe and reliable operation.
The electrical connections for single- or double gates are
given in Illustration 9.
The control box containing the motor control module is to be
fitted with cable entry at bottom (Illustration 10). It should
not be continuously exposed to direct sunlight. For weather
protection, we recommend the fitting of a small protection
roof.
Thanks to the electronic control unit, fine adjustment of the
push-pull torque is possible. When correctly adjusted, gate
movement can be easily blocked by hand.
For the OPEN and CLOSED positions, the gate requires
a stable end stop as the swing gate actuator unit is not
fitted with limit switches and the electronic controls are
switched off by time.
CONNECTION OVERVIEW
The control unit should be connected up last, i.e. after the
motor has been mounted, the necessary cables laid and the
Infrared Sensors or contact strips fixed in place.
In the case of permanent mounting, means of separating the
system from the mains must be provided. The contact
spacing of the main switch used in this connection must be
at least 3 mm.
NOTE:
In these instructions, relay contacts are designated as
NC (normally closed) and NO (normally open).
• NC contacts are closed, and open when actuated.
• NO contacts are open, and close when actuated.
