The fill parameters (pre-fill value, pre-act contact, main contact, tolerance and
optimization) depend on material properties. Menu item '473:Material Data' lets you
store 2 parameter records (corresponding) to 2 different material properties).
Parameter record is selected upon setpoint input in form of the material number.
For details of fill parameters see item 'Parameters'.
Refilling
Weigh hopper is automatically refilled from surge hopper via a gate/valve (Output 3).
Refilling commences as soon as the amount in weigh hopper has fallen below the
value of parameter 'Fill Weight' and continues until the value of parameter 'Max. Fill
Weight' is reached. Set these parameters using function block.
Refilling takes place (i.e. Output D-Fill='1') if
1. discharge operation is complete, and
2. gross weight in hopper is smaller than the value of parameter 'Fill Weight'.
Refilling continues until the value of parameter 'Max. Fill Weight' is reached. With the
use of different parameter settings, single and multiple fill operations can be realized.
Single Filling
With single fill operations, set parameters Fill Weight and Max.Fill Weight to the
same value (in excess of setpoint).
Multiple Filling
With multiple fill operations, set max. Fill Weight parameter to a value exceeding the
total amount to be discharged. Ensure that Fill Weight parameter value is smaller than
setpoint.
