LINK Systems OmniLink II Press Automation Control - Manual (Page 21)

Section 2.3.3 Wiring 115VAC Power From Press Control to Operator Terminal
Pull red, white and green 16 gauge wires in the 115VAC conduit between the OmniLink II Operator
Terminal enclosure and the press control (along with other wiring to be run in this conduit) and connect
as shown in Figure 2.13. The control transformer in the press control will preferably be used to supply
the 115VAC power for all the components of the OmniLink II Press Automation Control. As shown
previously in Figure 2.3, all the modules for the system have a dual power connector plug so that,
normally, power can be wired from module to module without having to put two (2) wires under a single
terminal. The exception to this is the dual connector on the R/D-Brake Monitor Module when optional
modules are used with the system. Three sets of wires must be wired to the dual terminal for Connector
5 of the R/D-Brake Monitor Module when optional modules are used: the incoming power from the
press control, the outgoing power to the OmniLink II LCD Operator Terminal, and the outgoing power
to the first optional module. This is shown in Figure 2.12 with two wires under each top terminal.
Figure 2.12 Wiring to the R/D-Brake Monitor Module 115VAC Power Plug
The power consumption of the OmniLink II Press Automation Control base system (Operator Terminal
and Resolver) is 24VA (0.2Amp at 115VAC). The maximum power required for each 16 input Die
Protection and Process Monitor is 56VA (.48Amp at 115VAC), although this power is dependent on the
number and power requirements of sensors used and will rarely be required in most applications. The
maximum power required for each PLS/Logic Unit Module is 30VA (.26A at 115VAC). The typical
OmniLink II Press Automation Control will usually require less than 1Amp at 115VAC, but as options
expand the system, 2 to 3 Amps may be required for very large systems. The control transformer in the
existing press control should be adequate to supply the OmniLink II system power for most applications,
but for larger systems, an additional control transformer or another source of 115VAC power may be
required.
