1128600 SmartPAC 2 with WPC 2000 Integration User Manual
2-32 Installation
WPC 2000 user inputs allow you to connect signals from other equipment in order to monitor
auxiliary press functions such as lubrication systems. WPC 2000 provides connections for
two pairs of control-reliable, cross-checked inputs and seven independent inputs that are not
control reliable.
When an input issues a Stop command by opening a normally closed (N/C) relay, a fault code
for the input(s) appears on the SmartPAC 2 display. Stop types for all inputs except cross-
checked user input pair 10/11 are set to E-Stop by default; input pair 10/11 is set to E-Stop/
Lockout. All inputs except input pair 10/11 can be reconfigured by the user on the Press
Control User Interlock Menu in SmartPAC 2 Initialization (see
User Interlocks
, page 4-24).
Inputs 1-7 can be changed to Top-Stop or E-Stop/Lockout. Cross-checked input pair 8/9 can
be changed to E-stop/Lockout. If you have SmartPAC 2 firmware version 3.32 or higher and
WPC 2000 firmware version 1.70 or higher, an additional stop type, Top-stop/Lockout, is
available for inputs 1-7. Wiring connection and fault code for each input are shown in
Table 2-6, page 2-33.
The cross-checked input pairs generate a fault either when one or both inputs in the pair are
open or when the inputs “disagree” (i.e., one input is open, the other closed) for longer than
100 msec. Cross-checked input pair 10/11 can be used to detect critical safety problems such
as the removal of die receptacle blocks.
E-Stop/Lockout and Top-Stop/Lockout stop types not only issue a Stop command and display
the appropriate fault code but also simultaneously open the Lockout relay and display the
Lockout message on the SmartPAC 2 display. To clear the Lockout message, turn the Stroke
Select switch to OFF and then back to INCH (see
Wiring the Lockout Relay
, page 2-34 and
Lockout Message
, page 7-3).
You can wire the Lockout relay to your motor starter so that ungrounding of a user input or of
either input in an input pair will shut off the motor.
To wire the user inputs, run conductors from the appropriate terminal number on the Main
Processor board to your equipment and then back to 24 Vdc or ground, as shown in
Table 2-6 and Figure 3 at the end of the manual. (There are several available “Ground” and
“+24 Vdc” terminals on the Main Processor board from which to choose.) Figure 13 at the
back of the manual provides an example of how to wire safety devices to the cross-checked
CHECK PRESS TO MAKE SURE IT STOPS WHEN USER INPUT ACTUATES
• WPC 2000 comes from the factory with the inputs bypassed by jumpers. Make sure to remove
the appropriate jumper from the Main Processor board connector when you wire a user input.
Otherwise, WPC 2000 will not receive the signal from the input. Leave all unused inputs
jumpered/bypassed.
• Perform checkout procedures to ensure that the user inputs are wired correctly and that WPC
2000 responds correctly when the user input faults (see page 2-113).
Failure to comply with these instructions will result in death or serious injury.
