Wiring the Auxiliary Output
WPC 1000 provides an output called Auxiliary 1 (pin #14 on the WPC 1000 Control board).
Auxiliary 1 is normally closed (N/C), or On. The output opens, or turns Off, when a fault
condition occurs, an E-stop string opens, or a light curtain is interrupted while the press is
running. The output can also be programmed to turn Off during an Interrupted Stroke (see
page 4-3 for an explanation of Interrupted Stroke).
Auxiliary Output 1 can be wired to a customer-supplied control relay and used to stop
auxiliary equipment such as scrap choppers, conveyors, etc. when one of the conditions
described above causes the press to stop. When a warning beacon is connected to the control
relay, the beacon illuminates when a fault occurs and Aux. Output 1 opens.
Wiring, state changes, and change conditions for Auxiliary Output 1 are provided in
Table 2-5. Wiring connections are also shown in Table 2-16, page 2-69 and in Figure 2 at the
back of the manual.
Aux. Output 1 response to an Interrupted Stroke is controlled by option switch 8 on the WPC
1000 Control board. Switch settings are shown in Table 2-6, page 2-31.
