SmartPAC 2 with WPC Integration
The cross-checked pairs are inputs 8 & 9 and inputs 10 & 11. Each pair is programmable for
ESTOP or ESTOP/LOCKOUT. These input pairs cause WPC to e-stop the press and
generate errors under either of these conditions:
One or both inputs in a pair are open.
The inputs in a pair "disagree" for longer than 100 msec. ("Disagree" means that one
input is open and the other is closed.)
Input pairs 8 & 9 and 10 & 11 are always activated and cannot be turned off. If you do not
want to use one or both pairs of inputs, leave them wired to ground, as indicated in
Table 2 - 2, below. For more information about how the cross-checked user inputs work, see
"User Interlocks," page 225 in the Initialization chapter. As a help to troubleshooting and
installation, you can also display the status of the interlocks from Initialization mode. See
"Using the WPC Input Status Display" in Chapter 7, page 420.
Wire the inputs according to Table 2 - 2, below, and Figures 3 and 14 at the end of the
manual. Figure 14 included an example of how to connect safety devices.
