Electronic Controller
The Gardner Denver Version 2.0 XMX Demand Expander is provided with a controller using the
Allen Bradley MicroLogix programmable controller. This controller performs as a stand-alone
controller however when connected through its Ethernet port to the Series 1000 system
controller, performs under the control of the master control instructions.
The controller should be wall mounted at eye level in close proximity to the Demand Expander.
The controller has input and output ports for the following:
P3 Storage Pressure –
(Terminals A1+ and A1-) Used only when connected by Ethernet to the ESP 20/20 Series 1000
controller and provides the storage pressure upstream of the Demand Expander to the master
controller.
This is not used when the controller is functioning as a stand-alone device.
P4 System Pressure –
(Terminals A2+ and A2-) wire to the downstream pressure transmitter mounted on the XMX
Demand Expander. Provides the control variable to the controller for valve control.
Valve Control –
(Terminals O1+ and O1-) connects to the valve positioner and provides the control to maintain
accurate system pressure.
Field Wiring Terminals
Shielded cables with twisted pairs should be used for the transmitter and valve control wiring.
Beldon catalog number 9363 or equal is recommended.
Once all of the power, signal and control wiring is in place, the unit can be energized with 115
VAC power and the processor will indicate the following screen on its LC display. Pressure and
valve position will reflect the actual values however.
