Terminals Relay 3 (14a/14c)
o Tare measurement
o Batch Ready
o Min/Max
Output active when the relay picks up. Depending on the software
configuration, the relay can be used for signaling Tare measure-

-
Batch Ready:
Relay picks up when batch weight is reached. Measurement is
stopped.
-
Min/Max:
You can select in the software if the relay picks up when dropping

Digital input 1 (18a/18c)
o Belt stop
o Erase ext. batch
o Batch mode
-
Belt stop
