SETUP AND OPERATION

CONTROL AND FUNCTIONS

All pumps feature

Display panel - it controls and overviews pump modes, parameters and on/off status.

Digital input RUN/0V – to put pump in RUN/STANDBY state.

Relay output - signalizes pumps status.
Variant NMT(D) MAX C with NMTC module has:

10-step switch - it allows us to change relay output, analog inputs/outputs and resetting the pumps
communication configuration.

Analog inputs - gives us 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 connection - offers control over all pump functions and settings (pumps variables, digital inputs,
error overview).

Modbus connection - gives us the 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 we do
not recommend using the night mode while using external signals.
