SETUP AND OPERATION

5.1

CONTROL AND FUNCTIONS

The pump can be controlled by display panel, 10-step switch, analog inputs, modbus or Ethernet connection.

Display panel controls and overviews pump modes, parameters and on/off status,

10-step switch allows changing of relay output, analog inputs/outputs and resetting the pumps
communication configuration,

Analog inputs gives control over the pump (start, stop, max. curve, min. curve, 0 - 10 V, 4 – 20 mA, ...),

Analog outputs are used for getting analog information about the pumps performance (errors, speed,
mode, flow, height),

Relay output signalizes pumps status,

Ethernet connections offers control over all pump functions and settings (pumps variables, digital
inputs, error overview),

Modbus connection gives overview of all parameters and settings (pumps variables, analog
inputs/outputs, error overview).
Several signals will influence the pump operation. For this reason, settings have different priorities as shown in
the table below. If two or more functions are active at the same time, the one with highest priority will take
precedence.

All inputs are not available in every mode of operation.

In night mode the external signals and Modbus stop signal become active. Due to the possibility of confusion
it is not recommended using the night mode while using external signals.
