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
dosing monitor to the corresponding sockets on the front side of the con‐
trol. In case of uncertainty - see chapter "Overview of equipment and con‐
trol elements"
CAUTION!
Danger resulting from unnoticed diaphragm rupture
All pumps ordered with an electric diaphragm rupture
sensor need to be electrically installed.
– Electrically connect the enclosed diaphragm rupture
sensor.
Only with flammable media:
WARNING!
Fire danger
The electric diaphragm rupture sensor must stop the
pump immediately after a diaphragm rupture and trigger
an alarm.
The pump must only be returned to service once a new
diaphragm has been fitted.
