6.5 Connection of digital outputs (4 x DQ)
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 can be directly
found at the weighing module SIWAREX WP241 and are not connected through to the
terminal board.
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 via menu 1.5.1 "Digital In & Outputs"
The 24 V power supply for the digital outputs is provided via terminals 3L+ and 3M with
electrical isolation.
