6.20 DR25 Dosing system parameters

6.19.11 Adopt corrected fine-/trailing values to DR23 automatically
[adoptCorrectedValues]
At the initial start of a dosing with "Material A", the electronic weighing system calculates the
shut-off points for the coarse/fine signal according to settings from DR23 (fine/trailing weight).
If the P-controller is active, the fine/trailing weight of "Material A" internally (DR30 or DR31) is
corrected or optimized by the controller during operation if necessary.
If there is now a change to "Material B" that entails different parameters, the corrected fine/
trailing weight of "Material A" would have to be read from DR30 or DR31 and copied to DR23
before the change so that, at the next loading of "Material A", the optimized values would be
used directly at the start.
To automate this copying, the "Adopt corrected fine/trailing value to DR 23 automatically"
parameter can be set to "YES" or "1".
6.19.12

Max. control access of fine time controller [maximumControllAccessTController]

With activated fine time controller you can define to what maximum extent the fine weight can
be adjusted. Depending on the "Parameter relation" setting (DR 24), the value must be
specified and interpreted as a percentage of the setpoint (DR 20) or as an absolute weight
value.
6.20 DR25 Dosing system parameters
6.20.1

Maximum single set point [maximumSingleSetPoint]

This parameter limits the set point in DR 20 and thus defines the maximum capacity of the
scale. The setting must be less than or equal to the maximum weight (DR 3).
6.20.2

Minimum automatic tare weight (% of max.) [minimumAutomaticTareWeight]

This parameter defines a minimum weight that must be tared at the start of dosing. It applies
only when a dosing start with taring is set in DR 25.
The parameter can be used to prevent dosing from being started even though, for example, no
empty container is on the scale. In this case, the minimum tare weight should correspond to the
empty weight of the container to be filled.
6.20.3

Maximum automatic tare weight (% of max.) [maximumAutomaticTareWeight]

This parameter defines a maximum weight that may be tared at the start of dosing; it applies
only when a dosing start with taring is set in DR25.
The parameter can be used to prevent overfilling an already prefilled container.
