CAUTION!
Incoming signals can remain without effect
If the universal control wire, the external/pacing cable or
the level monitoring cable is shortened below 1.20 m,
the pump does not detect that it is connected. Conse‐
quently a warning message (for example) can be sup‐
pressed.

Connect the plugs of the level switch, diaphragm rupture sensor and
metering monitor to the corresponding sockets on the front side of the con‐
trol. If in doubt - refer to the "Overview of equipment and control elements”
chapter.
