(digital and analog* inputs).
*) With analog inputs, only inputs with units m/s, bar, mbar, Pa, Universal 000.0, Universal 0000 are
possible.
A fault message is triggered and a fault issued at output "Flow delay start" if you
want to switch on the motor and if there is no checkback after a set time ("Motor
fault").
Since measurements can fluctuate during operation, a delay time can be set ("Flow
delay operation"). A fault message is triggered and a fault indicated at output
"Motor fault" if a flow signal fault occurs during operation.
