8.7.1
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 value as a
percentage of the measuring range. 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.
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.

8.7.2
Delay time for limit value 1 ON, delay time for limit value 2 ON
If the weight reaches the specified switch value, a delay time (defined in ms) is launched.
Once the delay time is over, the limit switch changes status provided the weight still reaches
the specified switch value.
8.7.3
Delay time for limit value 1 OFF, delay time for limit value 2 OFF
If the weight reaches the specified switch value, a delay time (defined in ms) is launched.
Once the delay time is over, the limit switch changes status provided the weight still reaches
the specified switch value.
