5- DESCRIPTION:
the FT180 photocell can work either without a synchronism (all the receivers can read the infra-red ray of all
transmitters) or with a digital synchronism (each receiver reads only the infra-red ray emitted by the transmitter with the same address set
with the dipswitches).
6- CABLING:
Figure 5 shows the electrical connection for use without a digital synchronism (turn OFF dipswitch number 3 of all
the transmitters and set a different address for each pair of photocells using dipswitches 1 -2 and 3 on both the transmitter and the receiver).
Figure 6 shows the electrical connection for use with a digital synchronism up to a maximum of 8 pairs. N.B.: for use with a digital synchro-
nism and AC power supply, all the number 1 (+) terminals of terminal block M1 must be connected to the same pole, and all the number 2
(-) terminals also of terminal block M1 must be connected to the other pole of the AC power supply, otherwise the photocells may not work
correctly.
7- KEY OF THE DIPSWITCHES AND JUMPERS
: Before turning on the power, set the dipswitches and jumpers as indicated in
