THE TIMER, PURIFICATION REACTOR AND PRESSURE REGULATOR.
9.10
Observing the INPUT PRESSURE gauge, Figures 1 and 6 (6), over a one or two-
minute period will not only indicate that the compressor is operating properly, as in
Section 9.4, but will also tell the operator whether the timer and purification reactor
are performing as they should. Once every thirty seconds there should be a sharp
drop (~15 or 20-psig) in input pressure followed within a few seconds by a rapid
discharge from the DUMP fitting, Figures 2 and 8 (6). If this is not the case, see
Section 10.10 for remedial action.
9.11
Observing the OUTPUT PRESSURE gauge, Figures 1 and 6 (8), and rotameter,
Figures 1 and 6 (7), will reveal whether there are problems with the purification
reactor, Figures 3 and 8 (1); the timer, Figures 4 and 7 (13); or the OUTPUT
PRESSURE REGULATOR, Figures 1 and 6 (9). A one or two-minute observation
of the rotameter should show the rotameter ball as remaining constant. If both the
rotameter ball and the OUTPUT PRESSURE gauge should show sudden drops
during a one-minute cycle, see Section 10.10 for cause and remedy.
