If you need to change the IP address of the pump because you want to
network multiple pumps, make sure you also enter the new address into the
connected twin pump.
• Single pumps can also work in alternating mode if you
connect and set them in a way outlined in the previous
paragraph.
• Both pumps start when power is applied and settle for
priority with the help of a random number. The operating
time is thus equally shared even if the power is often
interrupted.
5 Setup and operation
5.1 Control and functions
The pump can be controlled by display panel, digital inputs or Ethernet
connection.
• Display panel controls and overviews pump modes, parameters and
on/off,
• Digital inputs control basic pump operation (run, stop, maximum
set…),
• Relay output can signal pump status,
• Ethernet connections offers control over all pump functions and
settings (pump variables, digital inputs, error overview).
Several signals will influence the pump operation. For this reason, settings
have 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.
