LINK Systems OmniLink II Press Automation Control - Manual (Page 25)

Section 2.3.6 Wiring the Optional Setup Mode Input
The OmniLink II Press Automation Control provides an optional setup mode input that is used to bypass
certain die protection and process monitoring functions, counters, and tonnage monitor low limits during
setup activities that require stroking the press. This avoids nuisance faults that have to be reset on the die
protection and tonnage monitor and false part counts based on stroking during setup activities. Most
presses will use the INCH mode as the setup mode. It also allows a fixed setup mode speed to be set for
variable speed presses with the Analog Input/Output option. An isolated contact that closes in the INCH
mode must be used as an input. If you don’t have a spare INCH mode contact on the mode selector
switch, one solution is to remove an existing switch contact closed only in INCH from the circuit and
add a relay with 2 normally open contacts to the control circuit. Use the contact closed in INCH mode
to energize the relay coil, use one normally open contact of the relay to insert in the control circuit where
the INCH contact was previously located, and use the second normally open contact as the Setup Mode
input to the OmniLink. Figure 2.15 shows the wiring of this setup mode input. Run wiring in a conduit
reserved for low voltage circuits between press control and OmniLink operator terminal.
