Operability

11.9.1 Local operation
Rotational movement display
The shaft' s rotational movement is indicated by a reflector disk fitted on drive shaft of the
rotary paddle and can be monitored through a sight opening in the drive/terminal cover. The
disk' s viewing area is lit up by an LED to make it easier to see.
If rotation monitoring (optional) detects an error, the LED flashes.
Setting the switching threshold (sensitivity)
The switching threshold can be adapted to the weight of the bulk solids in 3 stages via an
operating element that is accessible from above (also possible during operation):
• Minimum: 80 g/l (4.99 lb/ft³)
• Adjustable in 3 stages depending on the density of the bulk solids: low, medium (factory
default), high
