11.3 End Switches
Check if the inductive end switches are functioning correctly.
Move the wing until fully closed position by hand. The wing should be stopped by the
mechanical end stop and a “Lc” indication must appear on the display of the controller
board.
Move the wing until fully open position by hand. The wing should be stopped by the
mechanical end stop and a “Lo” indication must appear on the display of the controller
board.
11.4 Alignment of the Photocells
Align, for all the photocells (max. 4 pieces), installed on the gate, the transmitter with
the receiver. Therefore follow the procedure as described below. After alignment each
individual interruption of the IR-beam of a photocell must trigger a “Pc” indication on
the display of the controller.
1. One-pair photocell set-up
In a ‘one-pair photocell’ set-up, only one pair of photocells
is used. The receiver is placed in the guiding post and the
transmitter is placed in the end post.
It is mainly sufficient to align the photocells this way that
they ‘look’ at each other. To align the photocells, loosen the
‘block’-screw inside the photocell and manually align the
lens to ‘look’ at the other photocell.
ATTENTION!
Do not forget to tighten the screw after completion of alignment.
Tip: if the photocells suffer from interference with sunlight and/or other light sources,
it is recommended to align the receiver so that is ‘looks down’ from the straight line
between the receiver and the transmitter.
2. Two-pair photocell set-up
In a ‘two-pair photocell’ set-up, two pairs of photocells are used. The receiver of
the first pair is placed in the guiding post and the corresponding transmitter is
placed in the end post. The receiver of the second pair is placed in the end post and
the corresponding receiver is placed in the guiding post. This way the two pairs of
photocells cannot interfere with each other.
