13.9 Digital inputs/outputs
Available inputs/outputs depend on the functional
module fitted in the pump:
* See section 19. Identification of functional
module.
You can select if the interface is to be used as input
or output. The output is an open collector and you
can connect it to e.g. an external relay or controller
such as a PLC.
