10 Section 10 – Setup & Operation of the Pneumatic Purge / Purge &
Cleaning Attachment on a Model MP1200 Melt Indexer w/WLD
The Pneumatic Purge and the Purge/Cleaning Attachment were designed to be used with a
MP1200M Melt Indexer equipped with the Motorized Weight Lowering Device (MWD). The Purge
Cylinder will allow the test charge to be purged to a predetermined starting point prior to a test
and/or to purge the remaining material after the test. The Cleaning Cylinder can be used (after
raising the WLD to its top position) with the Piston Extractor Assembly to remove the piston rod
assembly after a test and with the extended cleaning tool to help to operator clean the bore. Both
features may be operated manually from the LCD touch screen or programmed for semi-automatic
operation when using Tinius Olsen’s Horizon software MI package.
The PPC attachment and mounting hardware/accessories will be packed separately in the shipping
container. The PPC attachment, air regulator w/bracket and exhaust muffler are removed from the
MP1200 for shipment and must be re-installed at set-up. Refer to Drawing 5-6-819 for the Purge
Only system and 5-6-820 for the Purge & Clean system. The air hoses are also marked and
disconnected from the cylinders. Contact Tinius Olsen if you have any questions or problems
during setup.
