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.

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.
