4.5 Internal Air Cartridge Filter
The
1000 Series
contains a Cartridge Filter in the base housing. The Cartridge
Filter is designed to be the last line of defense to protect the AFD from
contamination. The Cartridge Filter is not designed to be the sole means of AFD
supply air filtration. The pneumatic supply system must be configured as described
in Section 4.4. If the filter becomes clogged the
1000 Series
will not function
properly. Replacement Cartridge Filters may be purchased from PushCorp (Part
No. PAR01943-1), or from the manufacturer directly (Parker, Part No. 050-05-DQ).
To remove the Cartridge Filter loosen the Cartridge Filter Holder located on the side
of the AFD base housing, See Figure 5. Remove the Cartridge Filter and perform a
visual inspection. The condition of the Cartridge Filter will give an indication of the
quality of your supply air system. Place a new Cartridge Filter on the Cartridge
Filter Holder and insert them into the AFD base housing. Tighten the Cartridge
Filter Holder to a torque of 11.6 lb-ft. (15.8 N-m).
5.0 Adjusting Carriage Preload
The required preload on the
1000 Series
Linear Rails has been set at the factory for
optimal performance and, in general, should not require field adjustment. However,
there are situations that could arise that cause the Linear Rails to need adjustment.
Often a loose, or tight, Carriage on a new AFD is indicative of an improperly
designed process equipment bracket. If the problem disappears when the brackets
are removed then this is the case. Normally the Carriage will only require
adjustment after removal for field service.
To check for a loose Carriage, attempt to move the Carriage in a lateral direction as
shown in Figure 6. If the Carriage moves or seems to exhibit any "slop", then the
Linear Rail preload must be readjusted. A dial indicator is helpful, but not necessary
to diagnose and correct a loose Carriage.
A Carriage that is too tight will require additional force to move. This is often
detected during the weighting of the process equipment mounted on the Carriage.
The weight will be inconsistent, varying higher or lower each time the process
equipment is weighed.
The Linear Rails are attached to the underside of the Carriage with (6) six metric
M6x1 Socket Head Cap Screws. Located on the side of the Carriage are the two
Preload Adjustment Set Screws used to translate the Movable Linear Rail. Moving
the Linear Rail associated with the Preload Adjustment Set Screws is all that is
necessary to adjust the Carriage preload.
