Shredder blockage
- Industry:
- Processing machines
- Task:
- A shredder shreds different materials. The current draw when the blades are blocked varies depending on the material.
- Solution
- The use of a measuring transducer together with a PLC allows different thresholds to be set in the PLC for different materials. The measuring transducer measures the current drawn by the blade drive motor and sends an analogue signal to the PLC.
Depending on the selected material, the PLC can compare the measured value with the configured value, and stop the machine when necessary.
- Use/value:
- - Rapid shutdown in the event of blockage
- Motor protection
- Minimisation and prevention of downtime
