Page 16 12-Station Controllers VacTrac™ Conveying Systems
Mount the panel on a flat, vertical area. It should be a visible area
that gives your operator access to the control. The panel requires a
low voltage power drop as listed on the serial tag.
3-4 Making Electrical Connections
Refer to local electrical codes, the schematic and connection
diagrams supplied with this unit and the serial tag for wiring
considerations. Run all wiring in conduit if codes require it.
3-5 Making VacTrac Control Panel Power Drop
Wiring Connections
Plug the power cord supplied into a properly grounded, 3-slot,
115/1/50-60 VAC or 230/1/50-60 VAC receptacle specified on the
VacTrac™ control panel serial tag. The control enclosure draws
less than five (5) amps during normal operation at 115/1/50-60
VAC.
Important!
AEC/Whitlock recommends that you protect PLC memory
by providing the control panel with a dedicated circuit,
a true earth ground, and a spike/surge protector.
3-6 Connecting the Control Panel to Vacuum
Hoppers
Figure 2
Refer to the wiring connection drawing on Page 18 that applies to
your application.
1. Run a common +24 VDC wire and a common 0 (zero)
VDC wire from the controller to each vacuum hopper in the
VacTrac™ system.
Note: For safety, make sure that the +24 volt line is fused. The
size of the fuse depends on the number of stations installed.
A 4 amp fuse is sufficient for a 12-station installation.
