SETUP AND OPERATION

CONTROL AND FUNCTIONS

All pumps feature:
• Display panel - it controls and overviews pump modes, parameters and on/off status.
Variant Ego 2 (T) slim U features:
• Digital inputs: RUN – to start/stop the pump, MAX to run pump at maksimum head or maksimum speed
(Input MAX works only in combination with input RUN – look at prioritys!), MIN to run pump at minimum
head or minimum speed.
• 0-10 V analog input for changing reference point.
• Two relay outputs - signalizes pumps status.
Variant Ego 2 (T) slim C features:
• 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 II. 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.

5 All inputs are not available in every mode of operation.
6 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.
7 Not available if using Modbus communication.
