Ransburg RMA202 Test Stand 77918-08 - Manual (Page 16)

7. Manually turn up the water pressure to 70 psig
(read on the front panel) by adjusting the pres-
sure regulator on the pressure pot. Verify by
looking at the pressure gage for fluid pressure.
8. Verify the test station test bell cup is still on the
applicator.
9. Turn “Fluid Enable” Paint #1, Paint #2, and sol-
vent In to the “On” position.
10. Turn “Applicator Enable” switches Bell Sol-
vent, Paint #1, and Paint #2 Trigger (if equipped)
to the “On” position.
11. Visually inspect each of the coiled fluid tubes
to verify there is fluid in them.
12. Visually inspect around the applicator to in-
sure there are no visible water leakage.
13. Turn the fluid selector switch to the “Off” posi-
tion.

> Bell cup and shroud must be attached to
end of turbine.
14. Observe the test pressure gauge for 2 to 3
minutes. The leak pressure should stay con-
stant over this period. If it does not, locate the
source of the leak, repair it and retest the ap-
plicator.
15. If the system does not hold pressure, visually
inspect for leaks. Potential areas are paint and
dump valves and their seats.
16. Turn the fluid selector switch back to air. De-
pressurize the pressure pot.
17. Actuate the dump triggers and blow out the
lines per the procedure outlined in the “HV
Troubleshooting” in this section.
18. Remove the test bell from the end of the appli-
cator. Adequately blow out all fluid in the coil
and upper section of the applicator. Install the
production bell cup and shroud per the instruc-
tions in the most current RMA-202 applicator
service manual.
19. Dump contents of “dump bucket.”
TURBINE TESTS
The purpose of this test is to verify the applicator
rotates properly and sprays reasonable well. With
de-ionized or distilled water as the test fluid, it is
difficult to accurately access the spray performance
characteristics. However, it can give a relative
indication of how the bell will spray in production.
