4.14 Semi-Automatic Pneumatic Purge & Clean
The Semi-Automatic Pneumatic Purge and Cleaning Assist Attachment can be used only on
MP1200M models equipped with WLD (Weight Lowering Device). The assembly is attached to
the WLD and will allow users to purge the test charge to a predetermined starting point. The
operator will charge the material into the bore and start the test, lowering the WLD weight
platform to a predetermined height (determined by manually programming the MP1200
controller or using Horizon software). The purge feature is then engaged, applying a downward
force on the weight to purge the material from the bore until the weight is stopped by the weight
platform. At the end of the pre-programmed release time period, the weight platform fully
lowers and the test will continue normally until its conclusion. At the end of the test, the purge
feature can be activated to purge any remaining material from the bore. After the WLD is raised
to its top position and swings out of the way, the piston can be removed from the cylinder using
the Piston Extraction Tool (included). After the orifice (die) is removed, a cleaning rod is placed
in position by the technician. Cleaning patches are then placed over the bore and the ram is
activated, helping the operator to clean the bore.
