Caution!
The manufacturer recommends that you protect PLC memory by providing
the control panel with a dedicated circuit, a true earth ground, and a
spike/surge protector.

Connecting the Control Panel to Vacuum Receivers
Refer to the wiring connection drawings shown on the next page and to your conveying
control panel’s diagrams for general connections.

•
Wire the Atmospheric/Sequence-T solenoid (SOL) valve to the terminal provided in
the conveying system control panel enclosure.
•
Wire the Bin Full/Hopper Full switch (LS/PRS) to the terminal provided in the
conveying system 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 conveying
system.
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 conveying 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.
Note:
The conveying system control panel is supplied with a terminal strip
at the upper right corner for + positive and – negative wire
connections.

connections.
•
Be sure the solenoid and proximity switch(s) (if supplied) on vacuum
receivers are the same voltage (24 VDC or 115 VAC) as the
conveying system control panel control voltage. Consult the control
panel serial tag and the solenoid valve nameplates.

panel serial tag and the solenoid valve nameplates.
•
Wire size depends on control voltage, distance, number of vacuum
receivers, and the number of wires in each raceway. Consult a
qualified electrician.

•
Properly ground each receiver to reduce static build-up generated by
material conveying.
