Checking Boosted Pressure - NPK M20S Instruction Manual

TROUBLESHOOTING

CHECKING BOOSTED PRESSURE

NPK gauge assembly, P/N L017-8000 is available to directly check the boosted
pressure on all Material Processors. The pressure intensifier's have three test ports as
shown.
PROCEDURE:
1. Remove a plug from one of the test ports and install the male adapter (f2). Choose
the port that will give you the best gauge clearance and viewing.
2. Install the gauge (g23) into the swivel adapter (f1). (Use thread sealant).
3. Install the gauge and swivel adapter onto the male adapter. (No thread sealant
required.)
4. Close the jaws all the way. Pressure will rise to the point where intensification starts
(P1 on page 133). Then it will go up to the full boosted pressure of approximately
12,000 psi (800 bar).
intensification, click...click...click...etc., is normal. If the clicking continues rapidly
and will not slow down, there may be a problem with the intensifier or Material
Processor cylinder assemblies.
5. Open the jaws all the way. You will now read the relief setting of the jaw open
circuit. Note that the intensifier only works on jaw close. Jaw open sees the
Material Processor's or the carrier's relief valve pressure setting, whichever is
lower.
NOTE:
IF ADDITIONAL ASSISTANCE IS REQUIRED, CALL THE NPK SERVICE
DEPARTMENT AT 1-800-225-4379.
