The intensity of light is converted into a voltage by the detector/preamp m odule. The voltage is converted into a number by a volta ge-to-frequency (V/F) converter capable of 80,000 count resolution. The digitized signal, al ong with the other variables, are used by the CPU to compute the concentration using the above formula.

FIGURE 1.6 - ELECTRICAL SIGNAL CONNECTIONS 1.7 Electrical and pneumatic connections 1.7.1 Analog Output The analog output is a two pin connector on the rear panel (See Figure 1.6). The analog output can be configured for voltage or current output. The standard is a 0-5 volt output.
The outputs labeled ‘STATUS OUT’ are used to indicate instrument operational status and fault conditions. The outputs labeled ‘CHANNEL ID’ are used to indicate which channel(stream), the instrument is curren tly monitoring. The outputs labeled ‘ALARM OUT’ are used to indicate the st atus of the HI and HI-HI alarms for each channel.

1.8 Options 1.8.1 Stream Selector (3 or 6 Channel) This option allows the M450 to measure ozone at up to six differe nt sam pling points by using an internal stream selector. 3 or 6 ch annel stream selectors are available. This option includes digital outputs for HI and H I-HI alarms and a channel ID for each channel in the stream selector.
.
2.0 OPERATION 2.1 Key features The important features of the Teledyne API Model 450 O 3 Monitor are listed below. 2.1.1 O 3 readout The Teledyne API Model 450 O 3 Monitor constantly displays the current ozone reading (in units specified) in the upper right hand corner of the alphanumeric display.
There is one exception to this. The analog output voltage range is set by DIP Switches on the A/D-I/O board as shown in Section 5.3. 2.1.6 RS-232 interface The Teledyne API O 3 Monitor features an RS-232 interface which can output the instantaneous and/or average O 3 data to another computer.
Mode Field The mode field indicates the current mode of the Monitor. If it shows "AUTO #1", the instrument is in the automatic sequence m ode(multi-stream instrum ents only) and that stream #1 is the active stream. Table 2.1 lists all the possible m odes in the Monitor and their meanings.
Warning Message Meaning SYSTEM RESET Issued whenever Monitor is powered on RAM INITIALIZED RAM was erased ANA LAMP WARNING UV lam p < 2500mV OR => 5000mV ANA LAMP SHUTDOWN UV lamp temp control n.
LED State Meaning Green Off Not monitoring (1) On Monitoring normally Blinking Monitoring, Manual Mode Yellow Off No warnings exist Blinking Warnings exist Red Off No Alarm s active Blinking Alarms active (1) This occurs during all diagnost ics modes TABLE 2.
messages are still in effect, the warning m essa ges will re-appear after they have been cleared. The ALRM button is displayed when concentrati on alarms have been triggered. See Section 2.3.3 for operation of the Alarm menu. The MODE button will toggle the instrument be tween Auto and Manual modes.
that has been sitting in the sample line while that stream was inactive. During the dwell phase the Concentration field on the di splay (see Figure 2.1) will blink and the instrument will display the last concentrati on recorded for that stream .
condition, provided that the concentration fo r that stream has dropped below the alarm threshold. If the monitor is configured for Non-Latching alarms, the CLR button will not appear, and all alarms will automatically clear when the concentration drops below the alarm threshold.
3.0 SETUP MODE This section describes the setup variables wh ich are used to configure the Monitor. All the setup variables are stored in the Mon itor's EEPROM and are retained during power off and even when new software revisions are installed.
<CH CH> INS [1] DEL ENTR EXIT SETUP A.8 SEQUENCE:[1]23456 FIGURE 3.2 - SEQUENCE EDITING The current sequence is shown at the top center of the display as a string of digits. Each digit in the sequence represents a stream number. To edit a digit, press the <CH or CH> buttons until the digit you wish to edit is s hown in brackets [].
3.2 Stream Configuration (STRM) The stream configuration menu is used to set alarm thresholds, monitoring duration, and analog output ranges for each individual str eam. This m enu is accessed by pressing the STRM button from the setup menu. The stream configuration menu is shown in Figure 3.
Pressing the leftmost button on the display w ill toggle the HI Alarm on and off. Press ENTR to proceed to the next prompt. If th e HI-HI Alarm is set to ON then the next prompt will show: HI-HI ALARM LIMIT:0.300 PPM Edit the HI-HI alarm value and press ENTR to store the value.
3.4 Setting the time-of-day and date (CLK) To set the current time-of-day, which is used for determ ining when to do an automatic calibration and for time-stamping the RS-232 reports, press SETUP-CLK-TIME.
1) ALARM_BEEPER This variable enables or disables the audible beeper that sounds whenever one of the alarms has been triggered. The beeper sounds a slow beep if any of the ‘HI’ alarms are active and sounds a fast beep if any of the ‘HI-HI’ alarms are active.
4.0 Maintenance 4.1 Replacing the sample filter element If your Model 450 has been equipped with an internal or external sample filter, the Teflon filter elements must be replaced on a re gular basis to ensure accurate readings from the M450.
4.2 Cleaning Exterior Surfaces of the M450 If necessary, the front panel mask and keyboard of the M450 can be cleaned with a dam p cloth. Do not attempt to clean any of the other surfaces of the instrum ent. Do not submerge any part of the instrument in water or cleaning solution.
5.0 ADJUSTMENTS CAUTION RISK OF ELECTRICAL SHOCK. THE OPERATIONS OUTLINED IN THE FOLLOWING SECTIONS OF THIS CHAPTER ARE TO BE PERFORMED BY QUALIFIED MAINTENANCE PERSONNEL ONLY! 5.1 Calibration The Model 450 is calibrated to NIST traceable standards on the 0-1 ppm range prior to shipment.
UV Source Lamp and Detector Diagnostics O3 REF Value Meaning 4700 mV to 5000 mV The Source Lamp and Detector are operating, but adjustment is required 4000 mV to 4700 mV The Source Lamp and Detector are operating properly; no adjustment is needed 2500 mV to 4000 mV The Source Lamp and Detector are operating.
If it is not possible to achieve an acceptable O3 REF test Value by means of adjustm ent, it is possible that the lamp has deterior ated beyond its useful range and should be replaced. Lamp or Detector Failure: WARNING UV LIGHT PRESENT DO NOT LOOK DIRECTLY AT THE UV LAMP SINCE UV LIGHT COULD CAUSE EYE DAMAGE.
Full Scale Output Switch Settings 100 mV 1,6 = ON 1 V 1,5 = ON 5 V 1,4 = ON 10 V 1,3 = ON TABLE 4.2 V/F BOARD DIP SWITCH - RANGES FOR ANALOG OUTPUT 5.3.2 Current Output (Optional) To configure the M450 for 4-20mA current output, perform the following steps: 1.
4. The M450 display will read "ADJUST ZERO:A/D=xx.x MV.” Put the probe of a voltmeter between TP3(AGND) and TP9(DAC #0) on the top of the V/F card. 5. The value displayed by the voltmeter s hould be close(+/- 20 mV ) to the value on the M450 display.
4. is set up for current output and has not been setup for current output. To do this, press SET , select CURR as the output type and press ENTR . 5. Next press CAL to begin the calibration. At this point the display should show: This indicates that channel 0 calibrated.
