Flow Type
The “Flow Type” setting allows the user to select how the flow rate is determined.
Options are Calculated, Scaled AnInp2 or Digital Pulse.
• “Calculated” uses the flow rate setting “Pump Flow Rate” in the settings menus to calculate the current
Flow Rate.
• “Scaled AnInp2” uses an analogue sensor (ether current-loop or variable voltage ) to determine the
current Flow Rate.
• Digital Pulse uses a compatible digital output flow meter to determine the current Flow Rate.
Manual Run
Serial Comms selects how the onboard RS-485 serial port is used.
•
Output Cont Data options is a data logging option that allows the pump station
to be remotely or locally logged.
• Modbus Protocol allows modbus compatible interfaces to monitor and adjust values during operation.

The number of pumps visible in these screens is determined by the “number of pumps” screen within
the CONFIGURE menu.
