This section of the options menu allows the operation of the optional 3-relay
board available for the K3 indicator to be configured.
These 3 relay outputs can be used either for controlling an external signalling
of the high/low/ok limits in the running mode as a checkweigher (H-L mode)
or for the dosage of a product at two speeds. Moreover, it is possible to
select whether the dosage is performed for filling a receptacle on the scale
(loading) or for emptying a receptacle (unloading). The options in this section
of the menu are the following:
Running mode for controlling the optional relay board.
The relay outputs will be controlled by the H-L running

hIGh
limits.
The K3 relay closes when the weight is below the
LOW
value.
The relay outputs will be controlled by the dosage
