Filter monitoring
Note: Filter monitoring is not available with all machines.
A15 ES implements built-in filter monitoring for both process and regeneration filters and can also be
set to raise alarm if there is no filter installed. These alarm functions are individually selectable and
adjustable to allow the user t obtain desired functionality for the given installation, including its
requirements on the air, the type of dust and dirt collected in the filters, the ducting used and also
the changes over time that may come from updated or changed filter types.
The pressure drop over a filter of the type used in the A15 ES as a function of the air flow has the
appearance depicted below. The pressure drop over the increasingly more dirty filter will increase
more rapidly with an increase of the air flow as seen by the increasingly steep slope of the curve.
To get the alarms to trigger at the correct point in time with given installation will thus often require
the pressure drop settings to be changed. Installations with long ducting will cause the actual air
flows to change and, as a consequence, the user might find that the factory settings for the alarms do
not quite fit requirements.
To check or to change the filter monitoring settings, step to Setup and Maintenance menu using the
upper right button of the control panel. Select this menu and step down to find sub menu Filter
settings
under which both ’no filter’ and ’dirty filter’ alarm settings for both regeneration and process
filters are found.
