Oxygen Monitor Board
The oxygen sensor monitors the purity supplied from the PSA module. If the oxygen
purity decreases below the setpoint, low purity light on the PSA module will be on. If
the problem persists for more than 30 minutes, a low purity alarm will sound.
Oxygen Sample Regulator
A regulator before the oxygen monitor board regulates the pressure to 4-5 psig to
the oxygen monitor board. Refer to the section 7 for the regulator adjustment.
Pressure Switch
When the oxygen concentrator operates in AUTO mode,the pressure switch
monitors the oxygen pressure at the outlet of the oxygen concentrator. When the
pressure at the oxygen concentrator outlet increases to the pressure switch upper
setpoint, the pressure switch circuit closes and the oxygen concentrator starts a
timed shutdown that stops the unit at the end of the shutdown sequence (After 10
additional cycles). When the pressure at the oxygen concentrator outlet decreases
to the lower setpoint of the switch, the pressure switch opens to activate the oxygen
concentrator and the oxygen production begins. When the oxygen concentrator
operates in MANUAL mode, the pressure switch circuit remains open and the
oxygen concentrator cycles continuously. Refer to the Appendix A of the manual for
lower and upper setpoint settings of the pressure switch.
