POWER SUPPLY
The photocells are made to be powered with 24 Vdc ac. For
voltages lower than 18V plug in the jumper provided (fig.4).
SWITCH OUTPUT
3. OPEN contact with free field between TX and RX.
4. CLOSED contact with free field between TX and RX.
5. COMMON contact.
SYNCHRONISM
The beams from a pair of photocell in a system with two pairs of
photocells that are close together could interfere on the other pair
causing malfunction; in this case it is advised to activate the
synchronism if an alternating power supply is available.
To activate the synchronism, cut the jumpers in both transmitters
(detail 5 fig. 4) and invert the power supply on one of the photo-
cell pairs, see figure 5. If it is not possible to activate the synchro-
nism, then avoid positioning the two receivers on the same side
and the transmitters on the other, and alternate the receivers and
transmitters, fig. 6.
CENTRING AND TESTING
Check that voltage is the same as that set or required for the
model and switch power on.
At this point, if alignment of the pair is not completely wrong, the
receiver should switch the output. If this does not happen proceed
with centring.
To facilitate alignment, the inside bodies of both the transmitter and
receiver are mounted on springs and, with two screws, they can be
