8.24.2 Maximum single set point
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).
8.24.3 "Coarse" set value for analogue output
The analog output of WP251 can be used for direct activation of a dosing element (e.g.
vibratory pan, pump, etc.).
The parameter "Coarse set value for analogue output" is specified as a percentage
(0…100%) and references the range of the analog output set in DR 7 (0/4-20 mA).
As soon as WP251 activates the "Coarse signal" in weighing step 2, the configured value is
output as the analog output signal.
Example
"Coarse" set value for analogue output (DR 25) = 75%
Range analog output (DR 7) = 0-20 mA
→ When the "Coarse signal" is activated, 15 mA is output at the analog output.
