8.8.2
Limit value 1 ON, limit value 2 ON, limit value 1 OFF, limit value 2 OFF
The switch-on and switch-off points can be specified separately for each limit as a percentage
of the measuring range or as absolutely values (based on "Limit reference" parameter setting).
This allows both minimum and maximum value violation monitoring with hysteresis. A delay
time for switch-on and switch-off can also be specified. Either the current net weight or the
current gross weight can be selected as the reference value for limits 1 and 2. Negative limits
are only possible with input of absolute values. Negative limits as percentage are rejected.
Maximum value monitoring is implemented with the following specifications:
● Switch-on value > switch-off value
Minimum value monitoring is implemented with the following specification:
● Switch-on value < switch-off value
The diagram below illustrates the function of limit values 1 and 2.

8.8.3
Limit value "Empty" ON
The value for the empty range is a limit value below which the weighing module registers and
returns the status "empty". The values are entered as a percentage of the measuring range.
The "Empty" limit always refers to the current gross weight in the scale.
The setting, whether absolute or a percentage, also affects the "Empty" limit.
