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
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.
