DANGER
!
USER INPUTS ADD DELAY TO STOPPING TIME
DO NOT connect light curtains or other presence-sensing devices to any user inputs.
Cross-checked input pairs (8 & 9 and 10 & 11), though control reliable, are suitable only for
such applications as connecting to safety switches used with interlocking barrier guards.
Failure to comply with these instructions could result in death or serious injury.
DANGER
!
INCORRECT USE OF FUNCTION OF USER INPUT CROSS-CHECKED PAIRS 8 & 9 AND
10 & 11
On SmartPAC-integrated WPC units, input pairs 8 & 9 and 10 & 11 are cross-checked and
have the following functions, which are different from older model WPC units:
Wire or re-wire these inputs according to the needs of your installation, and program them as
necessary, following the instructions in this manual.
Failure to comply with these instructions will result in death or serious injury.
WPC has eleven user inputs, two pairs of which are cross-checked so they are control reliable
when wired correctly to safety devices. These cross-checked input pairs can be used to
connect such devices as interlocked barrier guards to WPC. 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.
Settings for Regular Inputs, 1 through 7
Follow the instructions in Chapter 4, "Setting User Interlocks for Customized Status Codes,"
to set the stop type and name for each of these inputs. For inputs 1 through 7, you can set the
stop type to e-stop, top stop, lockout or unused. If you do not want to use one of these inputs,
select "UNUSED." All unused inputs from 1 through 7 must be set to "UNUSED."
Settings for Cross-checked Input Pairs, 8 & 9 and 10 & 11
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.)
