of the MicroLink system. “IN3" is for future
product expansion and is not currently used.
The other four pin connector in the MicroLink
unit is for the on board relay. If there is no air
adjust or air adjust and slide adjust boards
installed, this relay will function as a stop relay.
When the counter limits are reaches, this relay
will send a stop signal to the press control. There
are two sets of relay contacts available. One set is
normally open. The other set is normally closed.
When used, the stop relay is energized (turned-on)
during run conditions, and de-energized (turned-
off) during stop conditions. When the relay is
energized (turned-on), the normally open contacts
are closed and the normally closed contacts are
open.
There are three serial port connections on the
main board and two serial port connections on the
‘piggy-back’ board inside the MicroLink
enclosure. The green connectors with three pins
on the main board are for special purposes, such
as a roll-feed interface, and are covered in a
separate communications manual, called the Feed
Interface manual. One of the five pin connectors
on the ‘piggy-back’ board is reserved for future
applications, the other is a LinkNet connection,
which is covered in the separate LinkNet manual.
Contact Link Systems for more information on
these special purpose serial communication ports.
There are no other wiring connections inside the
MicroLink unit. The MultiSet system is wired into
the connectors on the back access cover of the
unit. Complete installation information for the
MultiSet system is covered in the separate
MultiSet manual.
