Page 13: Electrical Connections
OWER UPPLY The Model 470 requires a +15 VDC power source capable of supplying 1.0 A. DC power is connected through the male DB-15 connector. The positive terminal of the power supply should be connected to pins 4 and 5 on the 15-pin connector and the common terminal should be connected to pins 3 and 15. -
Page 14: Zero Calibration Input
ALIBRATION NPUT The zero calibration input is located on Digital Input #1. To zero the Model 470, Digital Input #1 should be connected to the power common for at least 1 second. This can be accomplished using a Normally Open switch or relay. -
Page 15: Operation
ZEROING THE SENSOR Due to its innovative sensing technology, the Model 470 is a highly zero-stable instrument, but should be zeroed periodically. 1. Purge the sensor with an ozone-free reference fluid, typically deionized water, to get rid of dissolved ozone inside the optical chamber for about 15 minutes. -
Page 16: Troubleshooting
Calibrate at Zero (Section 3.2). Action may not be required immediately; otherwise, service soon (Section 5.1). Calibrate at zero (Section 3.2). Call for service (Section 5.1). Teledyne API Model 470 Dissolved Ozone Sensor User Manual 08681B DCN8036... -
Page 17: Status Output Descriptions
Channel gain factor has fallen to < 0.5. This value is calculated when the zero calibration is performed. When this output is on, it indicates a loss of optical transmission through the windows in the absorption cell or a calibration fault.

Page 18: Maintenance
Aside from occasional calibration as described in this manual, there is no maintenance required for the Model 470 in the field. The UV lamp is typically replaced once every 2-3 years at the factory; take action according to Table 4-2.
