LINK Systems OmniLink II Press Automation Control - Manual (Page 15)

August 30, 2002 Manual Version 1.0 2.6
The standard resolver used with the OmniLink II press Automation Control is the 2500 Resolver. A
5000 Resolver can optionally be used with the system. In either case, a spring loaded mounting base, as
shown in Figure 2.7, will be supplied with the resolver to maintain chain tension if the resolver is chain
and sprocket driven. Mount the resolver on the spring base. Mount the spring base to accommodate
alignment of chain and sprockets so that they may be driven by crank or eccentric shaft.
Figure 2.7 Resolver Mounted on Spring Base to Maintain Chain Tension for Chain Drive
Chain and sprockets may have been purchased from Link Systems. If so, the sprockets will be 35B28
(28 teeth) and chains will be size 35 roller chain. Link suggests that, if the customer provides chain and
sprocket, the same type be used. This resolver electronic offset during calibration can only correct +/-
10
o of mechanical misalignment, and 28 teeth make it easier to be within the offset that can be
corrected.. If you have a press that only provides access to an intermediate shaft or back shaft for
connection of the resolver, you will have to determine how many turns this shaft makes for each turn
of the crank or eccentric shaft. You must then use sprockets of different size, chosen to provide one turn
of the resolver for one turn of the crank or eccentric shaft.
Section 2.2.3 Mounting Optional Control and Monitoring Modules
If you have purchased Die Protection & Process Monitoring, PLS/Logic, Auto Sets, Tonnage &
Signature Monitoring, or other optional modules, these may be packaged in separate or combined
enclosures, depending on how they were ordered. Figure 2.8 shows the mounting dimensions for the 8
or 16 channel Die Protection and Process Monitor Module enclosure and the enclosure for a single
PLS/Logic Module. Mount the enclosures for these modules in locations where the enclosure doors can
be easily opened for module access and wiring. Multiple module enclosures will be shipped with
mounting dimensions inside the enclosure.
