Wire to POINT Guard I/O
Module
Figure 18 shows a wiring example of a 440G-MZ Power to Release safety switch
that is connected to a 1734 POINT Guard I/O™ module.
Figure 18 - 1734 Module and 440G-MZ Safety Switch Schematic
Figure 19 shows the General tab of the 1734-AENTR module properties.
The Input Status can be set to Rack Optimization, Enhanced Rack
Optimization, or Combined Status - Power - Muting as these settings are used
by the Dual Channel Input Stop (DCS) logic block to verify that the 1734-IB8S
switch is operational. The Output Data must be set to Test, as the test outputs
are used to generate test pulses for the output contactors, K1 and K2.
