5.5.13 DR 4 - Basis weight for monitoring the empty range
The limit value for monitoring the empty range can be defined in reference to the
gross weight or the net weight of the scale.
5.5.14 DR 4 - Empty range
The value for the empty range is a limit value. If the weight value is below this limit
value, SIWAREX FTA determines an “empty” status which is output as status
information.
5.5.15 DR 4 - Switch-on weight limit value 1
Switch-on and shut-off weights can be defined separately for a limit value. This
way, a minimum value monitor and a maximum value monitor can be made with
a hysteresis.
Maximum value monitor is created with the following entry:
Switch-on value > shut-off value
Minimum value monitor is created with the following entry:
Switch-on value < shut-off value
