Switching outputs
Configuration of the switching outputs
Switching output Out A:
This can be done either with the physical input variable flow rate [FLW] or the air consumption
measurement [ConS] derived from it.
Switching output Out B:
can only be used with the physical input variable flow rate.
Switching outputs Out A/Out B can be configured according to the setting range in the technical data
è
Tab. 13.
For the switching output Out A and Out B, the switching function threshold value or window comparator
can be selected independently of one another. Each switching output can have the switching element
function N/C contact (NC – normally closed) or N/O contact (NO – normally open) separately allocated

Switching points [SP] and hysteresis [HY] can be set corresponding to the setting ranges in the
technical data table
