1128600 SmartPAC 2 with WPC 2000 Integration User Manual
2-36 Installation
When switch 8 is set to OFF, Auxiliary Output 1 opens, or turns Off, at the occurrence of an
Interrupted Stroke. When switch 8 is set to ON, the output turns Off during an Interrupted
Stroke only when there is also a fault or Emergency-stop condition; otherwise, the output
remains On during an Interrupted Stroke. See Auxiliary Output 1 Response to Interrupted
Stroke, page 4-40 for additional details.
The switch 8 ON setting allows the press to be “inched” during an Interrupted Stroke, when
the WPC 2000 is in Two-hand Maintained Single-stroke mode. Normally, in Two-hand
Maintained Single-stroke, the operator must hold down the Run/Inch palm buttons until the
press reaches its Top-stop position in order to avoid another Interrupted Stroke. With switch 8
set to ON, the operator may release the Run/Inch buttons while inching the press to Top-stop
without initiating an 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.
Auxiliary Output 2
Auxiliary Output 2 is normally open (N/O), or Off. The output closes to ground, or turns on,
whenever there is an interrupted stroke or fault condition or the press is placed in Inch mode.
Auxiliary Output 2 can be connected to the Setup Mode inputs of DiPro 1500 and AutoSet
1500/1504 Plus. The output is used to disable green sensors in DiPro 1500 or repeatability
setpoints in AutoSet 1500/1504 Plus whenever the press is switched to Inch mode or an
interrupted stroke or fault condition occurs. A customer-supplied output relay can be wired
into this circuit. Refer to the applicable manuals for wiring details.
Auxiliary Output 3
Auxiliary Output 3 is normally open (N/O), or Off. The output closes, or turns On, when the
DSV is energized. When Bar Control is in use (see Operating the Press in Bar Mode,
page 6-53), Aux. Output 3 remains open, or Off, when the DSV is energized.
Auxiliary Output 3 can be wired to the input check circuit of DiPro 1500 or ProCam 1500 and
is used to prevent Loss of Rotation faults on these units when Bar Control is activated.
When WPC 2000 is in Bar Control mode, the DSV is energized to enable the crankshaft to be
turned by hand. Under normal conditions, whenever the DSV is energized, Aux. Output 3
turns On, sending a low-voltage (i.e., 24 Vdc) input check signal to the DiPro 1500 or ProCam
1500.
DiPro/ProCam 1500 uses the input check signal to initiate monitoring of the programmed start
time limit, the interval within which the crankshaft must begin rotating in order to avoid a
Loss of Rotation fault. In Bar Control mode, Aux. Output 3 disables the input check signal,
preventing the 1500 unit from monitoring the start time limit.
Wire Auxiliary Output 3 to the “A” connection of the input check circuit of DiPro 1500 or
ProCam 1500. Wire one of the +24 Vdc outputs on the WPC 2000 Main Processor board
(pins #37 through #42) to the “B” connection of DiPro 1500 or ProCam 1500. If your DiPro
