2.7.5.2   Stock Silo Control

 

A regrind silo can have (optional) three sensors to detect high- low- and middle. If the 

 

controller has these sensors, ‘Stock-Silo’ regrind control can be activated, choosing menu 

 (F1) 

‘controller / protected parameters’

.

 

If the high-sensor is true, the silo is almost full. Therefore more regrind will be dispensed. 

 

This is the same as described in ‘empty regrind control’. This will be done until the middle 

 

sensor is not true anymore. In a defi ned number of steps the process will dispense the 

 

original setting of the recipe.

 

If the low-sensor is true, the silo is almost empty. Therefore less regrind will be dispensed. 

 

This is the inverse as described in ‘empty regrind control’. This will be done until the 

 

middle sensor will become true. In a defi ned number of steps the process will dispense 

 

the original setting of the recipe.
