switched off if it overheats. The motor is automatically switched on again once it has
cooled down.
ƒThree-phase AC motor: The motor monitoring is displayed and reset via the connec-
ted switchgear.
High water alarm with collective fault signal
When the high water level is reached, there is an audible and visual alarm signal. Forced
switch-on of the pump takes place. Furthermore, the collective fault signalling contact
is activated. An external alarm (horn, SMS via SmartHome connection) can be triggered
via the potential-free contact.

Product description en
Installation and operating instructions Wilo-DrainLift SANI-L 11
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 produced is channelled into the collection reservoir via the inlet pipe,
where it collects. When the water level reaches the switch-on level, the pump is
switched on. The collected sewage is pumped into the connected pressure pipe. When
the switch-off level is reached, the pump is deactivated after the set follow-up time. A
pump cycling occurs each time the pump is switched off.
When the high water level is reached, both pumps are switched on (forced switch-on).
The high water LED or display shows an alarm signal. Additionally, an audible alarm sig-
nal can be output via the internal buzzer. Furthermore, the output for the collective
fault signal (SSM) is activated.
4.5 Operation with frequency con-
verter Operation on the frequency converter is not permitted.
