Baking cabinet­ exhaust fan

The functioning of the exhaust fan in a baking cabinet must be monitored
Industry:
Process industry
Series/Measures
cos phi
Product:
G2CU400V10AL10
Data sheet:
Task:
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
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.
Use/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
