Monitoring devices

Monitoring of motor winding

The motor has thermal motor monitoring with bimetallic sensor:

• Single-phase AC motor: The motor monitoring is self-switching. The motor switches off if it overheats. The motor automatically switches on again when it has cooled down.
• Three-phase AC motor: The motor monitoring is displayed and reset through the connected switchgear.

High water alarm with collective fault signal

When the water comes to the switch-on level, a sound and visual alarm signal starts. The pump automatically switches on. Furthermore, the collective fault signalling contact is activated. An external alarm (horn, SMS through SmartHome connection) can be triggered through the potential-free contact.

When the water drops below the high water level, the pump switches off after the set follow-up time. The alarm signal is acknowledged automatically.
