7.3.2 AUTOMATIC FILTER CLEANING.
The automatic filter cleaning triggers itself when the dust extractor reaches about -0.2bar of
vacuum, as suction becomes poor and the filter requires cleaning. It can be triggered manually by
pressing the button for ‘’FORCED CLEANING”
pos.1 . In some cases (depend on the tools used on the
grinding machine) before reaching -0.2 bar the dust extractor will accumulate enough dust for
several bag changes. To avoid choking the vacuum with dust before reaching -0.2bar there is a
potentiometer
pos.2 with 11 positions. Each division corresponds to 5 minutes (pos.1-5min. pos.11-
55min.). This potentiometer sets the dust release interval, which lasts about 5 seconds. For example
if the dust extractor accumulates 15 kg dust in 15 minutes and the dust extractor is still far from -
0.2bar of vacuum, it needs to be discharged to prevent choking the pre-separator and maintaining its
high level of efficiency.
In case of emergency:
If the automatic system stop for some reason, there is an alternative way to clean the filter.
Remove the cotter pin pos.3 and eject the axle pos. 4. Once the actuator is detached use the axle to
rotate the inlet valve pos.6. Once the valve is closed and the system is under vacuum, rotate the axle
pos. 5 to clean the filter. Repeat the procedure with the lever 3 to 5 times and then open the valve to
its working position.
IMPORTANT: The axle pos. 5 has a hole in it with a diameter of 12mm (0.47 inch). Use a
metal rod or big screwdriver as a lever to rotate the axle.
