3-29 Making VacTrac Control Panel Power Drop
Wiring Connections
Plug the power cord supplied into a properly grounded, 3-slot,
115/1/60 VAC or 230/1/60 VAC receptacle as specified on the
VacTrac control panel serial tag. The control enclosure draws less
than 5 amps during normal operation at 115/1/60 VAC.
!
CAUTION
AEC recommends that you protect PLC memory
by providing the control panel with a dedicated circuit,
a true earth ground, and a spike/surge protector.
3-30 Connecting the Control Panel to Vacuum
Receivers
Figures 29 and 30
Refer to wiring connection drawings following this section for
your specific application.
• Wire the Atmospheric/Sequence-T solenoid ( SOL ) valve to
the terminal provided in the VacTrac control panel enclosure.
• Wire the Bin Full/Hopper Full switch (
LS/PRS ) to the
terminal provided in the VacTrac control panel enclosure.
• On 115 VAC control voltage systems, run a common hot
(115 VAC) wire and a common neutral wire from the
controller to each vacuum receiver in the VacTrac system.
• On 24 VDC control voltage systems, run a common +24
VDC wire and a common 0 (zero) VDC wire from the
controller to each vacuum receiver in the VacTrac system.
• On all systems, run two wires to each vacuum hopper: one
each from the controller to the Bin-Full switch ( LS ) and to
the Atmospheric/Sequence-T solenoid ( SOL ) valve.
Notes: • The VacTrac control panel is supplied with a
terminal strip at the upper right corner for + positive
and – negative wire connections.
