INSTALLATION AND ELECTRICAL CONNECTIONS
Operation with facing transmitter and receiver. Double safety
relay.
• Proceed as shown in Figure 4-5.
• Depending on the cable routing position, drill holes in the
base in the prearranged area (see Fig. 6).
• Proceed as shown in Figure 7 using rawlplugs (Ø max
5 mm) and corresponding screws (not included).
• Connect the cables in the terminals according to the dia-
gram (Fig. 14): 4 on the RX photocell and 2 the TX photo-
cell, from the respective control unit input.
• Apply silicone to seal the cable entry hole (Fig. 8).
• Before closing the photocell, test the transmitter (TX pho-
tocell) with the receiver (RX photocell) and check on the
receiver that the red alignment light (LED1) switches o
(Fig. 9).
• Proceed as shown in Figure 10-11.
TESTING
Test for the correct operation of the photocells.
