3. Make sure that the solenoid and the proximity switch (if
supplied) on vacuum hoppers are the same voltage (24
VDC) as the SCC 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.
4-5 Connecting the Control Panel to the Pump Package
1. Wire the pump package motor starter coil (M) to the
terminal provided in the SCC control panel enclosure.
2. Wire the pump package vacuum relief valve solenoid
(SOL A) to the terminal provided in the SCC control
panel enclosure.
3. Wire the pump package vacuum switch (VS) to the
terminal located in the SCC control panel enclosure.
4. 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 SCC system.
