9.3.6 Ozone Generator

CAUTION - DANGER

Lethal voltages present inside Ozone Generator Turn off instrument before servicing. Unplug Generator before dis-assembling.

The ozone generator subsystem consists of a permeation drier, flowmeter, power supply - generator module, and power switch. The location of the components is illustrated in Figure 9-7. Ozone is generated by drying ambient air, passing the air between two electrodes that have a large oscillating electric field generated by a high voltage transformer.

Common faults in the ozone generator are:

1.A leak or some other failure in the drier will let ambient air into the generator. There is enough water vapor in room air to cause the generator to make nitric acid aerosol. It is very corrosive and causes the generator cartridge to short out due to salt build-up. This reduces the ozone concentration generated which can cause the analyzer to be non-linear due to insufficient ozone concentration.

2.Contaminated ozone generator cartridge. Salts and oxgenated hydrocarbons can be removed by rinsing with 10% nitric acid at 50° C, followed by de-ionized water rinse, then dry air purge.

3.Shorts, open circuits, arcing. Because of the very high voltages, the glass ozone generator cartridge may crack and cause an internal arc or short circuit. Measure the voltage between TP-4 and TP-5 on the Ozone Generator Driver Board. The voltage should be 0.045 ± .005 VDC, indicating that the drive current is about .45 A. If the value is either zero or significantly greater than 0.45, the ozone generator is faulty.
