7.2.1
Control connectors
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. Consequently a warning
message (for example) can be suppressed.
– 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
If the pump has been ordered with an electric diaphragm rup‐
ture sensor, it must also be electrically installed.
– Electrically connect the enclosed diaphragm rupture
sensor.
Only with combustible media:
CAUTION!
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 dia‐
phragm has been fitted.

Output relay
If another switching function is required, the pump can be reprogrammed
in the
‘Relay’
menu.
The relay can be retrofitted and operates once it is plugged into the relay
board.
