Connecting the Control Panel to the Pump Package

Note: Consult the specific schematics and Operation & Instruction manual supplied with your controller for your specific application.

Wire the pump package motor starter coil (M) to the terminal provided in the conveying system control panel enclosure.

Wire the pump package vacuum relief valve solenoid (SOL A) to the terminal provided in the conveying system control panel enclosure.

Wire the pump package high vacuum switch (VS) to the terminal located in the conveying system control panel enclosure.

On SPDB pumps, wire the pump package blowback solenoid (SOL B) to the terminal located 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 the pump package in the conveying system.

On 24 VDC control voltage systems, run a common +24 VDC wire and a common 0 (zero) VDC wire from the controller to the pump package in the conveying system.

Note: Make sure that the pump motor starter, the vacuum relief valve solenoid, and the blowback solenoid (if supplied) 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 pump package serial tag.

Wire size depends on control voltage, distance, number of vacuum hoppers, and the number of wires in each raceway. Consult a qualified electrician.
