6.5 Connection of digital outputs (4 x DQ)
CAUTION
Unknown assignment of digital outputs
The assignment of the digital outputs is not known at the time of connection. Digital outputs
can be active immediately after turning on the power supply. This may damage parts of the
system.
Do not create a connection with the digital outputs before you know the assignment of the
digital outputs.
The electronic weighing system described here has four digital outputs. They are not
permanently assigned to process values in the delivery state. Assignment of these digital
outputs to functions as well as definition of the response in the event of a fault is carried out
during commissioning by parameter assignment of data record 7. The 24 V power supply for
the digital outputs is provided via terminals 3L+ and 3M with electrical isolation.
