Typical Pumping Operation
Several common control variables including flow,
pressure, and level can be used for operating a
booster system. Pump starts and stops are based on
the changes in these control variables. A VFD
(Variable Frequency Drive) is used to regulate the
speed of the pumps, replacing the function of a
control valve. Pressure recovery can be made
smoothly, resulting in power and cost savings.
When pressure is used as the key process variable,
the VFD pumping system constantly monitors
pressure to maintain the required demand. Pump
starts and stops are based on the changes in the
system pressure.
Other configurations are also possible. Consult your
Bell & Gossett Representative for proper operation of
your system.
Touch-Screen Panel Operation
This XLS HMI device manual describes the
operation of the touch-panel display, located on the
enclosure door of the control unit of the booster
station.
• Use a stylus to tap the buttons or fields
when using the touch-screen panel.
• Use the Enhanced Key Pad to enter
text or numbers in blank fields. Tap
and hold the stylus in a blank field to
open the Enhanced Key Pad pop up
screen.
• A USB Keyboard may also be used
instead of the Enhanced Key Pad.
Plug in the USB Keyboard into the
back of the display.
Danger: Electric Shock Hazard
Disconnect power before opening any electrical
enclosure. Any procedure requiring opening an
electrical enclosure must be performed by
qualified personnel only.
Failure to follow this guideline could result in
injury or death.

System Boot Up
Once the station is installed and field wiring is
complete, the system is ready to start. Upon
engaging power the control will start up and the
HMI will boot. Once the boot up sequence is
complete the user will see the station
information screen.
