2–Pump 12-Station Controllers 
Chapter 3:  Installation 
15 
Connecting the Control Panel to Vacuum Hoppers 
Refer to the wiring connection diagram in Figure 1 on the next page that applies to your 
application. 
Note:  Wire size depends on control voltage, distance, number of vacuum 
hoppers, and the number of wires in each raceway. Consult a qualified 
electrician. 
1.  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 hopper in the 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. 
2.  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. 
3.  Make sure that the solenoid and the proximity switch (if supplied) on vacuum 
hoppers are the same voltage (24 VDC) as the control panel voltage. Consult the 
control panel serial tag and the solenoid valve nameplates. 
4.  Wire size depends on control voltage, distance, number of vacuum hoppers, and the 
number of wires in each raceway.  Consult a qualified electrician. 
5.  Properly ground each hopper to reduce static build up generated by material 
conveying.  
Connecting the Control Panel to the Pump Package 
1.  Wire the pump package motor starter coil (M) to the terminal provided in the control 
panel enclosure. 
2.  Wire the pump package vacuum relief valve solenoid (SOL A) to the terminal 
provided in the control panel enclosure. 
3.  Wire the pump package vacuum switch (VS) to the terminal located in the control 
panel enclosure. 
4.  On vacuum pumps with blowback, wire the pump package blowback solenoid (SOL 
B) to the terminal located in the control panel enclosure. 
5.  On 24 VDC control voltage systems, run a common +24 VDC wire and a common 0 
(zero) VDC wire from the controller to each pump package in the system.
