Wiring to 1734
Guard Point I/O
The 440G-LZ safety switch can be connected to a 1734 Guard Point I/O. The
cordset (catalog number 889D-F8NB) has 24 AWG wires, which allows three
wires to be connected to one terminal.
Figure 17 on page 44
shows a wiring example of a Power-to-Lock switch with a
Door Status auxiliary signal. The PLC logic checks to see if the door is closed
before issuing a lock command. The schematic for this example is shown in
Figure 22 on page 47
.
