1.3 Principle of Operation The detection of ozone molecules is based on absorption of 254 nm UV light due to an internal electronic resonance of the O3 molecule. The Model 460H uses a mercury lamp constructed so that a large majority of the light emitted is at the 254nm wavelength. Light from the la...

2.2 Pneumatic Connections 1. Connect a ¼” exhaust line to the fitting labeled ‘Exhaust.’ This line should be vented to an outside area, since the exhaust gas may still contain trace levels of ozone that may not be completely removed by the built-in the ozone scrubber. CAUTION Exhaust gas from the M4...

7.0 Sensor and System Troubleshooting This chapter gives guidelines for diagnosing system and sensor malfunctions using the five digital Status Outputs provided by the M460H. All troubleshooting should be done after the M460H has been turned on and allowed to warm up for at least 15 minutes. 7.1 Sta...

7.3 Invalid Reading The normal state for the Invalid Reading output is OFF. If this output turns on, this indicates that the M460H is still operational, but a system fault or calibration fault exists that may make the current ozone reading invalid. The Invalid Reading output is turned on for any of ...
