Fill level monitoring

Connect a float switch to monitor the fill level. The switch contact of the float switch can act as an NO contact or an NC contact. An alarm signal works with a closed contact according to the factory setting. An alarm signal can also work with an open contact.

Install the float switch according to the installation plan of the unit. Observe the following points:

• The float switch can move freely in the operating space (pump chamber, tank).
• Check contact type (NO contact or NC contact).
• Check “top” and “bottom” switching point.
