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.
– Do not shorten this cable below 1.20 m.
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.
If the pump has been ordered with an electric diaphragm rupture sensor, it
must also be electrically installed.
Electrically connect the diaphragm rupture sensor provided.
