Option 1 User Inputs C-1
Appendix C. Option 1 User Inputs
This appendix shows you how to install, wire, and troubleshoot WPC 2000 Option 1. Option
1 is a “daughter” board you can install on your WPC 2000 Main Processor board to increase
the number of user inputs available for connection of auxiliary equipment to WPC 2000.
Option 1 is compatible with WPC 2000 systems running WPC 2000 version 1.70 and higher.
By providing connections for other press-related equipment, user inputs allow you to monitor
auxiliary press functions such as lubrication systems, conveyors, etc. and provide additional
press protection and operator safety. Up to 7 non-control-reliable inputs and up to 2 pairs of
control-reliable, cross-checked inputs are standard on WPC 2000 units. The Option 1 board
enables you to connect up to 20 additional non-control-reliable inputs and up to 4 additional
control-reliable, cross-checked input pairs to WPC 2000 (see Table C-1, page C-2).
Option 1 user inputs, like WPC 2000 standard inputs, are programmed to stop the press
whenever connected equipment malfunctions. The type of stop (e.g., Top-stop, Emergency-
stop, etc.) is determined by the setting programmed for the specific input. These input stop
types are set at the factory and cannot be changed.
Ten of the non-control-reliable Option 1 user inputs are set for a stop type of Top-stop, eight
are set for E-stop, and two are programmed for E-stop/Lockout (see Table C-1). Of the
control-reliable, cross-checked input pairs, two are set for E-stop and two for E-stop/Lockout.
When any equipment connected via Option 1 user inputs to WPC 2000 issues a stop command
by opening a normally closed (N/C) input, WPC 2000 signals the press to perform the stop
type programmed for that input and displays the input’s fault code on the WPC 2000 display
(see Troubleshooting, page C-8 for a list of the fault codes assigned to Option 1 user inputs).
When a stop command is issued for user inputs 21 or 30 or input pairs 36/37 or 38/39, the
lockout relay also opens, causing “Loc” to appear on the display. The “Loc” message must be
cleared (by turning the Stroke Select switch to OFF, then to INCH or one of the other
operating modes) before the press can be restarted.
Ten of the non-control-reliable inputs have an input type of NPN, and ten are PNP (see
Table C-1). All of the control-reliable, cross-checked input pairs are PNP.
USER INPUTS 1 THROUGH 7 AND 12 THROUGH 31 NOT SUITABLE FOR SAFETY USE
DO NOT use inputs 1 through 7 and 12 through 31 as part of any personnel protection system.
These inputs are not control reliable.
Failure to comply with these instructions will result in death or serious injury.
