Baking cabinet­ exhaust fan

Product category
cos phi
Data Sheets

The functioning of the exhaust fan in a baking cabinet must be monitored. The fan is controlled with a frequency converter. When no air is being moved, for example because the impeller is damaged, a fault should be indicated.

Solution description

After the startup phase, the D24SC starts monitoring the cos phi. When there is no load or an underload, the cos phi falls below the threshold, and the monitoring relay issues a fault message.

Benefit/added value

– The cos phi monitor is suitable for use with frequency converters
– The monitoring takes place in the switch cabinet without any additional sensors
– No high-maintenance external monitoring components are needed
