Operating principle

The sewage flows into the collection tank through the inlet pipe. When the water comes to the switch-on level, the pump switches on. The collected sewage is pumped into the connected discharge pipe. When the water comes to the switch-off level, the pump switches off after the set follow-up time.

When the water comes to the high water level, the pump switches on (forced switch-on). The high water LED or display shows an alarm signal. Also, the internal buzzer can emit a sound alarm signal. Furthermore, the output for the collective fault signal (SSM) activates.
