Figure 2-1: Block Diagram of the Signal Processing Electronics In the presence of oxygen, the sensor(s) produce a current.
Operational Theory Model 3300ZB Teledyne Analytical Instruments 8 RS-232 (optional) output. The same digi tal information is also sent to a 8-bit digital to analog converter ( DAC) that produces the 0-1 0 VDC analog concentration signal and th e 0-10 VDC analog range ID output.
Trace Oxygen Analyzer Installation Teledyne Analytical Instruments 9 Inst allation Installation of the analyzer includes: 1. Unpacking the system. 2. Mounting the control unit to a wall. 3. Making the electrical connections. 4. Making the gas connections.
Installation Model 3300ZB Teledyne Analytical Instruments 10 3.2 Location and Mounting 3.2.1 Control Unit Installation The 3300ZB control unit is design ed to be wall-mounted in a general purpose, indoor area, away fr om moisture and the elem ents. The unit should be installed at view ing level in a sheltered area.
Trace Oxygen Analyzer Installation Teledyne Analytical Instruments 11 Figure 3-1: Rear Panel Electrical Connectors Analog Outputs: There are three DC output signal connectors with screw terminals on the p anel. There are two wires per output with the polarity noted.
Installation Model 3300ZB Teledyne Analytical Instruments 12 The specific descriptions for each type of alarm are as follows: HI Alarm Configured as high alarm (actuates when concentration is above threshold). Can be set anywhere within the full range of the analyzer (1- 1,000 ppm), but must be set ABOVE the threshold set for the LO Alarm.
Trace Oxygen Analyzer Installation Teledyne Analytical Instruments 13 The RS-232 protocol allows some flexibility in implementation in the choice of values for certain pa ram eters. Table 3-2 lists the RS-232 values required by the Mode l 3300ZB implementation.

Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 15 Operation 4.1 Introduction Once the analyzer has been mount ed, the gas lines connected, and the electrical connections made, the an alyzer can be configured for your application.
Operation Model 3300ZB Teledyne Analytical Instruments 16 4.2 Using the Function a nd Dat a Entry Buttons When one of the function buttons is being pressed, the analyzer is in the Setup mode or the Calibration mode.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 17 4.3.1 HI Range Setting the HI Range full-scale value defines the LEAST sensitiv e analysis range to be used.
Operation Model 3300ZB Teledyne Analytical Instruments 18 1. Press the SET LO ALARM function button once. 2. Within 5 seconds press either the or button to raise or lower the displayed value as require d, until the disp lay reads the desired concentration.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 19 3. As the display is blinking, once the readout appears stable, press either the or button to adjust the reading to coincide with the oxygen concentration of the span gas. Once set, the unit will enter Analyze Mode after approx imately five seconds after the last key press.
