3–Pump 33-Station Controllers 

Chapter 3:  Installation 

14 of 51 

1.  On 115 VAC control voltage systems, run a common hot (115 VAC) wire and 

a common neutral wire from the controller to each vacuum hopper in the 
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 hopper in the 
system. 

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.  

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, wire the pump package blowback solenoid (SOL B) to the 

terminal located in the control panel enclosure. 

5.  On 115 VAC control voltage systems, run a common hot (115 VAC) wire and 

a common neutral wire from the controller to each pump package in the 
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 pump package in the 
system.
