4.3 Monitoring devices Monitoring of motor winding
The motor is equipped with thermal motor monitoring with bimetallic sensor:
•Single-phase AC motor: The motor monitoring is self-switching. The motor is switched
off if it overheats. The motor is automatically switched on again once it has cooled
down.
•Three-phase AC motor: The motor monitoring is displayed and reset via the connected
switchgear.
High water alarm with collective fault signal
When the high water level is reached, an audible and visual alarm signal is given and the
switching on of the pump is automatically initiated. Furthermore, the collective fault sig-
naling contact is activated. An external alarm (horn, SMS via SmartHome connection) can be
triggered via the potential-free contact.
If the water drops below the high water level, the pump is deactivated once the follow-up
time has elapsed. The alarm signal is acknowledged automatically.
4.4 Operating principle The sewage is directed into the collection tank via the inlet pipe. When the water level
reaches the switch-on level, the pump is switched on. The collected sewage is pumped into
the connected discharge pipe. When the switch-off level is reached, the pump is deactiv-
ated after the set follow-up time.
When the high water level is reached, the pump is switched on (forced switch-on). The high
water LED or display shows an alarm signal. Additionally, the internal buzzer can emit an
audible alarm signal. Furthermore, the output for the collective fault signal (SSM) is activ-
ated.
4.5 Operation with frequency con-
verter
Operation with the frequency converter is not permitted.

WARNING
Head injuries due to lack of protective equipment!
Danger of (serious) injuries during work can occur. If a lifting accessory is
used, wear a safety helmet!
CAUTION
Beware of frost!
Frost can cause malfunctions and damage. Pay attention to local frost
depths. If the unit or discharge outlet are in the frost zone, stop the op-
eration of the unit during frost periods.
Also adhere to the following points if the lifting unit is installed in a pump chamber:
•Toxic or asphyxiating gases can build up during work.
•If toxic or asphyxiating gases accumulate, leave the workplace immediately.
•Note the diagonal dimension of the lifting unit.
•Install lifting accessory: even surface, clean and firm base. The storage area and installa-
tion location must be easily accessible.
•Attach two transport straps to the lifting unit. Secure the transport straps against slip-
ping. Only use technically approved lifting slings.
•If it is no longer safe to work due to the weather conditions (e.g. ice formation, strong
wind), stop work immediately.
6.4.1 Note on fixation material The lifting unit can be installed on various constructions (concrete and steel construction,
etc.). Select the fixation material which is suitable for the relevant construction. For correct
installation, observe the following instructions for the fixation material:
•Avoid tearing or chipping of the construction surface, observe the minimum edge dis-
tances.

•Only use components (e.g. screws, anchors, mortar cartridges) which are in perfect con-
dition.
6.4.2 Note on pipework The pipework is exposed to different pressures during operation. Pressure peaks can occur
(e.g. when closing the non-return valve) which may be several times higher than the pump
pressure, depending on the operating conditions. These different pressures stress the pip-
ing and the pipe connections. In order to ensure safe and proper operation, the piping and
pipe connections must be checked based on the following parameters and designed ac-
cording to the requirements:
•Pipes are self-supporting.
No tensile or compressive forces must act on the lifting unit.
