Carry out the electrical connections on the terminal board (Fig.2), bearing in
mind that the relay exchange in the detector refers to a powered and aligned
photocell.
Fix the photocell body by tightening the 4 screws provided into the relative
holes shown in Fig. 3.
OPTICAL CENTERING
For correct photocell operation, the emitter and the detector must be
aligned.
To aid alignment both the transmitter and the receiver have the inner body
mounted on springs and thanks to two screws adjustment may be made
horizontally and vertically (fig. 1); the receivers are also fitted with a red
indicator light that goes out when the photocell is centered.
Check operation by cutting off the infrared ray several times (the red indicator
light on the receiver should come on and the relay trip). This test should also
be repeated after having positioned the photocell cover.
The centering filter (part 1 of fig. 4) serves as another test to be sure that
even in the worst conditions, e.g. fog or rain, everything is in proper working
order.
The test is quick and easy: just place the film over one of the front "eyes" (fig.
5) and check that the photocell works correctly; if it does not, this means that
the range is at its limit or alignment is imperfect.
Caution: remember to remove the film at the end of the test.
SYNCHRONISM
In systems with two pairs of photocells positioned close together, the rays
of one device could interfere with the other causing malfunctioning. To avoid
this, if an alternating power supply is available it is advisable to activate the
synchronism mechanism.
To activate synchronism, cut the jumpers in both transmitters (part 1 of fig. 2)
and invert the power supply on one pair of photocells.
Should it be impossible to actuate synchronism, avoid placing the two
receivers on the same side and the transmitters on the other, instead
alternating receiver and transmitter.
