6.6.6 Fan running feedback
To make sure that the fan is running, it is possible to assign a digital input as a running feedback. The running feedback has to be
programmed through M-Logic. Here is an example.
The Fan A/B/C/D running command output tells the AGC that the fan is running. The output is found under Output, Command as
shown above.
6.6.7 Fan failure
It is possible to activate an alarm if the fan does not start. The fan failure alarm appears if the running feedback from the fan does
not appear. In parameters 6590 to 6620, the fan failure alarms are set up for fans A to D.
