10. FREQUENCY SELECTION

To prevent interference if installing more than one photocell, it
is possible to set a different work frequency for each photocell,
by choosing between 4 available values.
Set the frequency using the two dip switches on the receiver
and on the transmitter (see "Frequency selection" in section 1).
Select the same frequency on both the receiver and the
transmitter.
ATTENTION: SELECT NON-ADJACENT FREQUENCIES FOR BEAMS IN THE SAME SECTION (E.G.: CH1-
CH3, CH2-CH4, CH1-CH4). IF THERE ARE MORE THAN 2 BEAMS ON THE SAME SECTION, CROSS
OVER THE TRANSMITTERS AND RECEIVERS SO THAT THERE IS NO INTERFERENCE BETWEEN
ADJACENT FREQUENCIES.
Below some examples are shown of installations with several pairs of beams, with the indication of the lay-out
and the channel to set for the various pairs
