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 O molecule. The Model 465 uses a mercury lamp constructed so  
3
that a large majority of the light emitted is at the 254nm wavelength. Light from the lamp shines  
down a hollow quartz tube that is alternately filled with sample gas, then filled with gas scrubbed  
to remove ozone. The ratio of the intensity of light passing through the scrubbed gas to that of  
the sample forms a ratio I/I . This ratio forms the basis for the calculation of the ozone  
o
concentration.  
The Beer-Lambert equation, shown below, calculates the concentration of ozone from the ratio  
of light intensities.  
109  
29.92inHg  
o  
CO    
ln  
273o   
3
Where:  
I = Intensity of light passed through the sample  
Io = Intensity of light through sample free of ozone  
= absorption coefficient  
= path length  
CO = concentration of ozone in ppb  
3
T = sample temperature in degrees Kelvin  
P = pressure in inches of mercury  
As can be seen the concentration of ozone depends on more than the intensity ratio. Temperature  
and pressure influence the density of the sample. The density changes the number of ozone  
molecules in the absorption tube which impacts the amount of light removed from the light  
beam. These effects are addressed by directly measuring temperature and pressure and including  
their actual values in the calculation. The absorption coefficient is a number that reflects the  
inherent ability of ozone to absorb 254 nm light. Most current measurements place this value at  
-1  
-1  
308 cm atm at STP. The value of this number reflects the fact that ozone is a very efficient  
absorber of UV radiation which is why stratospheric ozone protects the life forms lower in the  
atmosphere from the harmful effects from solar UV radiation. Lastly, the absorption path length  
determines how many molecules are present in the column of gas in the absorption tube.

The intensity of light is converted into a voltage by a high resolution A/D (analog-to-digital)  
converter. The digitized signal and other variables are used by the CPU to compute the  
concentration using the above formula.  
About every 2.5 seconds the M465 completes a measurement cycle consisting of a 1 second wait  
period for the sample tube to flush, followed by a 150 ms measurement of the UV light intensity  
to obtain I. The sample valve is switched to admit scrubbed sample gas for 1 second, followed by  
a 150 ms measurement of the UV light intensity to obtain I . Measurement of the I every 2.5  
o
o
seconds eliminates instrument drift due to changing intensity of the lamp caused by aging and  
dirt.

4. GETTING STARTED  
The Model 465 is shipped with the following standard equipment:  
Power cord (Rack mount version only)  
Instruction manual.  
Upon receiving the Model 465 please do the following:  
1. Verify that there is no apparent shipping damage. (If damage has occurred please advise  
shipper first, then Teledyne API.)  
2. When installing the Model 465, allow a minimum of 4 inches for clearance at the back of  
the instrument (rack mount only) and 1 inch of clearance on each side for proper  
ventilation.  
3. Connect sample inlet line(s) to the sample port on rear panel or bottom panel of  
instrument. See Figure 4-2 or Figure 4-3 for rear panel pneumatic connections.  
CAUTION  
Connect the exhaust fitting on the rear panel (See Figure 4-2) to a suitable  
vent outside the monitor area.  
4. Ensure that there are no communication devices connected until after start-up is  
complete.  
5. For the NEMA configuration, the electrical connection must be hard-wired to the 3-pin  
connector on the mainboard labeled J23. AC power connection to the monitor should be  
made with 12-14 AWG stranded copper wire, connected to the monitor as follows:  
NOTE  
Sample tubing made from an inert material such as Teflon should  
be used to minimize sample degradation.  
Earth Ground (green): Connect the earth ground wire to the screw terminal lug on the  
chassis as shown in the Figure below. Do not connect the earth  
ground wire directly to the PCB connector on the mainboard PCB.  
Line (Black):  
Connect the Line wire to the connector on the mainboard PCB  
labeled “Line”.  
Neutral (White):  
Connect the Neutral wire to the connector on the mainboard PCB  
labeled “Neutral”.

Figure 4-4: Pneumatic Connections, NEMA Configuration, Multi-Stream  
4.1.1. Sample Gas Connection  
Sample gas connections are made to the ¼” tube fittings on the rear panel. For single stream  
monitors, use the fitting labeled “Sample Inlet.” For multi-stream monitors, the sample tubing is  
connected to the fittings labeled Stream 1, Stream 2, etc (See Figure 4-2, Figure 4-3, Figure 4-4)  
1/4" O.D. FEP (Teflon) tubing is recommended to connect the sample source to the monitor.  
Any fittings used in the sample lines should be constructed of stainless steel or Teflon.  
Teledyne API recommends that the length of tubing connecting the sample points to the monitor  
should be kept to 50 feet or less.  
NOTE  
For the sampling lines, use only ¼” O.D. FEP tubing. For best analytical performance, the  
tubing should be pre-conditioned to ozone prior to installation to minimize ozone loss in the  
sampling lines. Pre-conditioned ¼” FEP tubing is available from Teledyne API (Part number  
02639)

4.1.1.1. Sample Filtration  
The most important factor in maintaining an accurate and stable monitoring system for ozone is  
the cleanliness of entire pneumatic system leading up to (and including) the sensor assembly  
inside the instrument. Provision must be made for keeping dust and other particulate matter out  
of the monitor and upstream sample delivery tubing. The monitor is equipped with an internal  
particulate filter down-stream of the selector manifold.  
In addition, it is recommended that inlet filters be installed at the inlet of each sample line.  
These filters should be constructed of PTFE or other inert material to avoid degradation of the  
ozone concentration. Appropriate disposable inlet filters can be purchased from TAPI. See the  
Spare Parts list in Appendix A of this manual for ordering information.  
4.1.1.2. Sample System Design in Humid Environments  
Care must be taken in the design of the sampling system to ensure that water vapor does not  
condense in the sampling lines or in the instrument itself. The sample lines should be routed to  
avoid large temperature gradients along the lines. If sample is brought in from a hot, humid area  
into a much cooler area, then low power heating tape should be wrapped around the lines to keep  
the temperature of the sample lines up and avoid condensation. The lines should also not have  
loops or low points where water could collect.  
For applications that require sampling of very humid gas, a Sample Conditioner and/or a  
Permeation Gas Dryer may be required to lower sample gas humidity. A pneumatic block  
diagram with the locations of these M465L options is shown in Figure 4-5, followed by a  
description of each. Please contact the Teledyne API Sales Department for additional  
information.

Sample Conditioner Option  
The Sample Conditioner option is a water drop-out filter and a permeation gas dryer, designed  
for high-humidity environments where the sampling gas has been saturated with water vapor and  
may contain small amounts of condensed water. This coalescing filter removes not only liquid,  
but also particulates with a Teflon filter element. Refer to Section 9.8 for maintenance  
procedures.  
Due to the additional volume added by the water drop-out filter, there is an exception to the  
Response Time in the M465L specifications:  
The Response Time of an M465L instrument equipped with the Sample Conditioner option, will  
be <60 seconds to 95%.  
CAUTION  
The Sample Conditioner will NOT protect the unit from damage by  
large amounts of liquid, such as that ingested through immersion of  
the sample line.  
Furthermore, it is important to closely track the amount of water  
accumulating in the Water Drop-out Filter after the monitor has been  
installed and running: if excessive condensation is occurring in the  
sample lines leading to the monitor, then heat-traced lines should  
also be used to minimize condensation  
The Sample Conditioner option includes a Permeation Gas Dryer, which is available as an  
alternate option (described next) if humidity is the only concern and there is no risk of  
condensation.  
Permeation Gas Dryer Option  
The Permeation Gas Dryer serves to remove water vapor from sampling gas in a humid  
environment. It is an alternative option when there is no risk of condensation. The permeation  
material is a Teflon Type compound and has only a minimal effect on the ozone concentration in  
the sample stream. When the M465L is equipped with this option, the unit has been calibrated at  
the factory to compensate for any ozone loss in the permeation dryer.

4.1.2. Exhaust Connection  
Connect a ¼” OD vent line to the “Exhaust” fitting on the rear panel. This line must be vented  
outdoors or to an appropriate discharge system capable of handling ozone. Local regulations  
regarding the discharge of ozone to the atmosphere must be observed. Note that the monitor  
may be equipped with an internal ozone scrubber for removal of ozone from the exhaust stream.  
For safety reasons, the exhaust port must still be vented appropriately as described above.

4.2.  
Electrical I/O Connections  
4.2.1. Location of I/O Connectors in the NEMA  
Configuration  
In the NEMA configuration of the M465L, the I/O connectors are located internally in the  
instrument. See Figure 4-7 for their location. The relative position of the connectors and the  
pinout information is the same as the Rack-Mount configuration shown in Figure 4-6.  
Connection to these terminals is usually made via a conduit connection to the NEMA enclosure.  
A standard conduit penetration may be added to one of the walls of the enclosure for this  
purpose, or the existing penetration may be used.  
4.2.2. Analog Output  
The analog output is located at the “General I/O” connector (See Figure 4-6) and is labeled  
“ANA.” The analog output can be configured for 0-5V voltage or 4-20 mA current output. See  
Section 9.8 for details on verifying or changing the analog output hardware configuration.  
The analog output is automatically scaled to the range of the instrument, i.e. if the monitor range  
is 1000 PPB, then 5V would correspond to 1000 PPB and 0V would correspond to 0 PPB. See  
Section 7.2.7 for information on changing the range of the monitor.  
The M465L has an analog output step-test mode that can be used for verifying the operation of  
the analog output and calibration of external measurement equipment. This mode is described in  
Section 7.2.3.1.  
4.2.3. Status Outputs  
There are four instrument status outputs located at the “General I/O” connector. These status  
outputs mirror the state of the four diagnostic LEDs on the front panel.  
Electrically these outputs are SPST dry contact relay closures with a common contact, labeled  
‘C’ on the rear panel. They are capable of switching up to 50 VDC, 250mA maximum current.  
There are no polarity requirements, so the outputs can be used to sink or source current from the  
‘C’ pin, within the maximum voltage and current specified. Schematically, the outputs look as  
shown in Figure 4-8 below:

4.2.4. Hi-Current Relay Outputs  
Three form C relay outputs are provided on the rear panel on the nine pin connector (See Figure  
4-6). The relays are labeled “Relay 1,” “Relay 2,” and “Relay 3.”  
The relays are dry contact type form C (SPDT) relays with Normally Open (N.O.), Normally  
Closed (N.C.) and Common (COM) contacts. The relays are capable of driving loads of up to  
250VAC, 5A. For maximum contact life, the relays should only be used to drive resistive loads.  
Contact life may be dramatically shortened if inductive loads are driven without any provision  
for minimizing high voltage “inductive kick” that can occur.  
These relays have slightly different functions depending on whether the monitor is a single  
stream or multi-stream configuration.

4.2.5. Multi-Stream Relay Outputs (Optional)  
For instruments configured with the optional stream-selector, an additional set of output relays  
are provided on the rear panel and are labeled “Multi-Stream Outputs” (See Figure 4-6.)  
Electrically these outputs are SPST dry contact relay closures with a common contact, labeled  
‘C’ on the rear panel. They are capable of switching up to 50 VDC, 250mA maximum current.  
There are no polarity requirements, so the outputs can be used to sink or source current from the  
‘C’ pin. One common terminal is provided for the six relays on each connector (See Figure 4-6.)

7. OPERATION  
7.1.  
Front Panel Overview  
The M465L front panel provides a number of functions in addition to displaying the current  
ozone concentration being measured. Figure 7-1 below shows the display and keypad portion of  
the front panel.  
Figure 7-1: Front Panel Display  
7.1.1. Ozone Concentration Display  
The 4-character LED display in the center of the front panel normally shows the current ozone  
concentration being measured by the M465. While displaying concentration, one of the unit-of-  
measure indicators (i.e., PPM, PPB, or UGM) should be backlit, indicating the current  
measurement units. If none of these indicators are backlit, then the display is in Menu mode or  
Startup mode and is not displaying the concentration. If the display is in Menu mode, the  
display can be returned to Concentration mode by repeatedly pressing the CFG button until one  
of the unit-of-measure indicators is lit. Note that even when the display is in Menu mode,  
normal measurement and stream selector operation will continue in the background.  
7.1.2. Menu Navigation Keypad  
The menu navigation keypad (CFG, ENT and UP/DOWN buttons) is used to navigate the  
various menu items available on the M465L. The menus allow the user to view operational  
parameters of the instrument as well as view and modify the configuration of the instrument.  
See Section 7.2 for more detailed information.

7.1.3. Stream Selector Status/Control (Optional)  
The optional multi-channel stream selector can be controlled via the front panel. The stream  
selector operates in two modes, Auto and Manual. The Auto mode is normally the default mode.  
The ‘AUTO’ and ‘MAN’ LED’s show the current mode. To switch modes, press and hold the  
SELECT button for at least 2 seconds. When in Manual mode, momentarily pressing the  
SELECT button will switch to the next stream.  
The stream selector status is shown by the six LED’s labeled ‘SAMPLE POINT.’ One of the  
LED’s should always be lit, showing the current channel being measured. Note that for a three-  
channel instrument, only streams 1-3 can be measured. See Section 7.3 for additional details on  
the operation of the stream selector.  
When the instrument is in its default configuration, there is a Manual mode timeout feature that  
will automatically return the stream selector to Auto mode when no keys are pressed for 10  
minutes. This is the recommended setting for instruments used for critical safety applications.  
This feature prevents the instrument from being inadvertently left in Manual mode, and  
subsequent loss of monitoring data from the other, unmeasured channels. For applications where  
Manual mode is the preferred mode of operation, this timeout feature can be turned off. See  
Section 7.2.6 for details on changing this setting.  
7.1.4. Concentration Alarm Status/Reset  
The M465L front panel displays the concentration alarm status of all channels being sampled.  
The row of LED’s labeled ‘ALARM STATUS’ shows the alarm status for each channel as  
follows:  
Table 7-1: Alarm LED’s  
Alarm Status LED Color  
Alarm State  
Green  
Amber  
Red  
No alarm active  
‘HI’ alarm active  
‘HI-HI’ alarm active  
NOTE  
If the alarms are configured for latching operation, then the RESET button can be used to  
attempt to reset all alarms. Note that alarms can only be reset if the concentration measured for a  
specific channel has subsequently dropped below the alarm limit. If the alarms are configured  
for non-latching operation, they will be automatically cleared when the concentration falls below  
the alarm threshold. The RESET button has no effect when the alarms are configured for non-  
latching operation.  
See Sections 7.2.7, 4.2.4, and 4.2.5 for additional details on concentration alarms.

7.1.5. Status LEDs  
There are four Status LED’s on the front panel to the right of the concentration display. These  
LED’s provide a quick view of the instrument’s Status as well as an indication of any problems  
that may exist. The normal state for these LED’s after the initial 20 minute warm-up period is as  
follows:

If any of these LED’s are in a different state than shown above, then some adjustment or  
troubleshooting should be performed. See Section 10.1 for more detailed information.  
7.2.  
Front Panel Menus  
The M465L has an interactive menu structure that can be operated from the front panel. From  
within this menu structure, the operator can view real-time parameters such as temperature and  
pressure, view configuration information, and edit setup parameters such as alarm limits.  
Figure 7-2 below shows the menu structure as well as the buttons that are used to navigate it.  
Starting with the display in Concentration mode, press CFG to enter Menu mode. At this point  
the unit-of-measure LED should turn off and the first level of the Menu tree will be active.  
Pressing the UP/DOWN arrows will now select from the items available at this menu level.  
Press ENT to enter one of these sub-menus or press CFG to back out of this menu level back to  
Concentration mode.  
7.2.1. Menu Navigation Basics  
1. Press CFG from Concentration mode to enter Menu mode.  
2. Once in Menu mode, CFG will move backwards one level in the menu structure and  
ENT will move forward.  
3. Each menu level contains an EXIT selection. Selecting EXIT and pressing ENT will exit  
the Menu mode and return the display to Concentration mode.  
4. The Menu mode will timeout if no buttons are pressed within 30 seconds, and the  
instrument will automatically return to Concentration mode.

7.2.3. DIAG Menu  
The DIAG menu (See  
Figure 7-2) contains functions that are useful for testing and configuring external equipment that  
may be connected to the rear panel I/O of the instrument.  
7.2.3.1. Analog Step-Test  
When placed in this mode, the instrument will automatically step the analog output (See Section  
4.2.2 for details on the analog output connection) through 5 points from 0 to 100 % and display  
the current value on the front panel. The operator can suspend the automatic cycling and  
manually control the stepping by pressing either one of the UP / DOWN arrow buttons. To  
resume automatic cycling, exit the function by pressing CFG and re-enter by pressing ENT.

7.2.3.4. Zero Calibration  
The zero calibration allows the instrument to calibrate its internal ozone offset factor. This  
should only be done with a source of zero air connected to the “Sample In” port of the M465L.  
Allow the instrument to stabilize on the zero air source before attempting to zero. This normally  
takes 10-15 minutes.  
When entering the Zero Calibration menu, the prompt “ENT TO CAL” appears on the display.  
Simply confirm the calibration by pressing the ENT button to perform the calibration (to abort  
the calibration, press and hold the CFG button to return to the previous menu level.) After  
pressing ENT, the instrument will automatically exit the menu mode and return to Concentration  
mode. The concentration reading should quickly go to zero. Please note that while measuring  
zero air, a certain amount of noise or “dithering” of the concentration about the zero point will  
occur and is normal. This noise is typically 1-3 ppb (0.001 - 0.003 ppm) in magnitude.

7.2.3.5. Span Calibration  
The span calibration allows the instrument to calibrate its internal slope factor based on a known  
ozone concentration. This should be done with a source of ozone span gas connected to the  
“Sample In” port of the M465L. Allow the instrument to stabilize on the span gas source for a  
minimum of 1 hour before performing the span calibration.  
NOTE  
A Span Calibration should only be performed with a precision  
source of ozone calibration gas, such as a Teledyne API Model  
700 or Model 703 calibrator. Simple ozone generators without a  
measurement feedback system should never be used for  
performing span calibrations.  
If you are unsure regarding the suitability of a particular source of  
calibration gas, contact Customer Service at Teledyne API for  
assistance.  
Figure 7-4 below shows the Span Cal menu. After the instrument has stabilized on the source of  
span gas, navigate to the Span Cal menu (See  
Figure 7-2) and Press ENT. Next enter the Span Target concentration (the actual concentration  
of ozone being supplied to the monitor) and press ENT. The display will next show a  
confirmation menu, ENT TO SPAN. Press ENT to perform the Span Calibration, or CFG to  
abort back to the start. If the calibration is successful, the display will return to the concentration  
menu and the monitor reading should change adjust to read very close to the target value. If the  
calibration cannot be performed, an OUT OF RANGE error will be displayed. Press ENT to  
confirm and the display will return to the start of the Span Cal menu.  
If the OUT OF RANGE error occurs, it means the Span Cal cannot be performed because it  
would result in an out of range slope value for the monitor. This means that either the sensor in  
the monitor is malfunctioning, causing improper readings, or the actual ozone concentration  
being supplied to the monitor is different than the target value being entered.

7.2.3.6. Flow Calibration (Optional Electronic Flowmeter only)  
The flow calibration allows the instrument to calibrate its internal flowmeter reading. This  
should be done with a calibrated flowmeter connected to the “Sample In” port of the M465L.  
Figure 7-5 below shows the Flow Cal menu. After the instrument has stabilized on the source of  
span gas, navigate to the Flow Cal menu (See  
Figure 7-2) and Press ENT. Next enter the Flow Cal target (the actual flow as measured at the  
sample inlet) and press ENT. The display will next show a confirmation menu, ENT TO CAL.  
Press ENT to perform the Flow Calibration, or CFG to abort back to the start. If the calibration  
is successful, the display will return to the concentration. If the calibration cannot be performed,  
an OUT OF RANGE error will be displayed. Press ENT to confirm and the display will return  
to the start of the Flow Cal menu.  
If the OUT OF RANGE error occurs, it means the Flow Cal cannot be performed because it  
would result in an out of range flow slope value for the monitor. This means that either the flow  
sensor in the monitor is malfunctioning, causing improper readings, or the actual flow is  
different than the target value being entered.

7.3.  
Multi-Stream Operation  
This section describes the operation of the Multi-Stream M465 in Automatic mode (AUTO) and  
Manual mode (MAN.)  
In AUTO mode the monitor is designed to continuously cycle through the enabled sampling  
streams (stream ENABLE set to ON), and skipping past the streams that are not enabled (stream  
ENABLE set to OFF). (The ENABLE parameter is accessed through the CFG-SETUP-STR[n]  
menu). In MAN mode the operator manually controls the cycling through enabled sampling  
streams by pressing the SELECT button. The stream cycling is accomplished by activating  
valves on the stream selector manifold on the rear panel to admit sample gas for a particular  
stream. Section 7.1.3 details the operation of the front panel stream selector interface.  
When the M465L first switches to a new sample stream, the instrument goes through a 30-  
second dwell phase where sample gas is pulled from the new sample stream but no readings are  
taken. The purpose of this dwell phase is to purge out any “old” sample gas that has been sitting  
in the sample line while that stream was inactive. During the dwell phase the Sample Point LED  
on the display (See Figure 7-1) will blink and the concentration display will show the last  
concentration recorded for that stream. After the 30 seconds has elapsed, the Sample Point LED  
will stop blinking and the current concentration will be displayed. The current stream will now  
be monitored for the rest of the measurement Duration that has been set for that stream (see  
Section 7.2.7 for details on configuring the individual streams.) The actual time period that the  
stream is measured is the measurement Duration minus the 30 second dwell. So a 1 minute  
measurement Duration consists of 30 seconds of dwell followed by 30 seconds of measurement.  
For systems that do not require a 30 second dwell between streams, this value can be changed  
using the DWEL Var. See Section 7.2.6 for additional details.

8. DIGITAL COMMUNICATIONS  
8.1.  
Digital Communications Overview  
The M465L comes equipped with a digital communications (Com) port that can be connected to  
a computer or digital data acquisition system. This Com port uses the standardized MODBUS®  
protocol and can be configured for RS232, RS485, or Ethernet (10 Mbit,) allowing for  
connections to a wide variety of devices and networks. See Section 8.2 for more information on  
configuring the Com port.  
The Com port can be used for data acquisition, alarm triggering, and instrument configuration.  
All the functions that are available at the front panel of the instrument can also be performed  
over the Com port.  
NOTE  
MODBUS Interface Software for the M465L is available for  
download from the TAPI website. Other TAPI software, such as  
APICom, does not currently support communications with the  
M465L.

8.5.  
Ethernet Configuration  
Ethernet is commonly used for factory automation busses with a computer or PLC acting as a  
master. The communications protocol used for the Ethernet configuration is MODBUS TCP/IP.  
For details on the MODBUS TCP/IP specification, please see http://www.modbus.org/.  
A Windows software application, DeviceInstaller, is available for configuring the Ethernet  
module used in the M465L. This application is available for download here:  
8.5.1. Hardware Setup for Configuring the Ethernet Module  
To make the first-time configuration of the Ethernet module as easy as possible, the module  
comes from the factory with DHCP enabled. The M465L can simply be plugged into a network  
with a DHCP server and an IP Address should be automatically assigned to, and stored in, the  
device.  
A simple network can easily be constructed for this purpose by using a small broadband router  
commonly used for home networks. The M465L and a PC can then be connected to the router  
and the router’s DHCP server will assign IP Addresses to both the PC and the M465L, enabling  
them to communicate.  
8.5.2. Verifying Network Hardware Connection  
With the M465L connected to a network and powered up, check the status of the two leds on the  
Ethernet connector on the rear panel. The left-hand LED should be lit; either amber or green  
indicating link status and the right-hand led should blink periodically, indicating activity on the  
network. See Table 8-5 below for more details on the status LED’s.  
If neither of the LED’s are lit, then the Ethernet module may not be powered up or the  
instrument may not be connected to a valid network. Check the COM port configuration per  
Section 8.2 and make sure that it is set to “Ethernet.”

8.5.3. Determining a Dynamically Assigned IP Address  
(DHCP Mode)  
The DeviceInstaller software application (See Section 8.5) can be used to search a network for  
instruments and determine the IP Address assigned by a DHCP server.  
1. Click Start->Programs->Lantronix DeviceInstaller->DeviceInstaller. If your PC  
has more than one network adapter, a message displays. Select an adapter and click OK.  
2. Click on the Search icon. After a moment a list of instruments on the network will be  
displayed. The M465L should be listed as an XPORT-IAP type device.  
3. Double-click on the device in the right-hand section of the DeviceInstaller window; a list  
of configuration parameters will be shown, including the IP Address. If multiple devices  
are shown, the correct one can be determined by matching the Hardware Address shown  
with the address printed on the label of the Ethernet module in the M465L. Note that the  
instrument cover must be removed to inspect this address in the instrument.  
8.5.4. Manually Assigning a Static IP Address  
For applications where the IP Address must remain constant, a static IP Address can be manually  
assigned to the instrument and the DHCP function must be disabled.  
1. Click Start->Programs->Lantronix DeviceInstaller->DeviceInstaller. If your PC  
has more than one network adapter, a message displays. Select an adapter and click OK.  
Note: If the unit already has an IP address (e.g., DHCP has assigned an IP  
address), click the Search icon and select the unit from the list of Lantronix  
device servers on the local network.  
2. Click the Assign IP icon.  
3. If prompted, enter the hardware address (on the product label) and click Next.  
4. Select Assign a specific IP address and click Next.  
5. Enter the IP address. The Subnet mask displays automatically based on the IP  
address; if desired, you may change it. On a local network, you can leave the Default  
gateway blank (all zeros). Click Next.  
6. Click the Assign button and wait several seconds until a confirmation message displays.  
Click Finish.  
7. Select the device from the main window list and select Ping from the Tools menu. The  
Ping Device dialog box shows the IP address of the selected unit.  
8. From the Tools menu, click the Ping button. The results display in the Status window.  
Click the Clear Status button to clear the window so you can ping the device again.  
Note: If you do not receive “Reply” messages, make sure the unit is properly  
attached to the network and that the IP address assigned is valid for the  
particular network segment you are working with. If you are not sure, check with  
your systems administrator.  
9. Click the Close button to close the dialog box and return to the main window.

UV Lamp Adjustment  
CAUTION  
GENERAL SAFETY HAZARD  
Do not look at the UV lamp while the unit is operating. UV light can  
cause eye damage. Always use safety glasses made from UV blocking  
material. (Generic plastic glasses are not adequate).  
WARNING - RISK OF ELECTRICAL SHOCK  
HIGH VOLTAGE MAY BE PRESENT WHEN POWER IS CONNECTED TO  
THE INSTRUMENT!  
1. Instrument should be running and warmed up for at least 20 minutes.  
2. With instrument running, remove the six screws and the top cover.  
3. Navigate the front panel menu to VIEW menu and scroll to REF display and press ENT.  
At this point there should be a scrolling display similar to “REF = XXXX MV.” See  
Section 7.2 for details on menu navigation.  
4. Locate the UV Detector adjustment pot on the forward end of the sensor module (see  
Figure 9-1 or Figure 9-2 above.)  
5. While observing the REF value on the display, slowly turn the pot to adjust the value.  
The target adjustment range is as high as possible within the range of 800 – 1150 mV.  
6. If the required adjustment cannot be achieved by adjusting the UV Detector pot alone,  
then additional adjustment can be made by loosening the two UV lamp setscrews on the  
UV lamp housing (see Figure 9-1 or Figure 9-2) and rotating the lamp. Rotate the lamp  
very slowly while observing the REF value on the display. Make sure the lamp does not  
pull out and remains seated in the housing while it is being rotated. Re-tighten the two  
setscrews when a desired point has been reached.  
7. If necessary, additional “fine tuning” can now be done with the UV Detector adjustment  
pot per step 5.  
8. Re-Install instrument cover and observe REF value on display for a couple minutes to  
verify it does not drift out of the adjustment range.

9.8.  
Water Drop-Out Filter (Option)  
Maintenance  
Located externally on the right side of the enclosure, the Water Drop-Out Filter (Section 4.1.1.2)  
should be checked periodically for water build-up and drained. To drain this filter:  
1. Disconnect the ozone supply line from the instrument.  
2. Shut off flow to the instrument using the needle valve on the front panel.  
3. Remove cap from the fitting located on the bottom of the filter and allow it to drain.  
4. Replace cap and adjust flow to instrument.  
Replacement of the particulate filter, a Teflon coalescing membrane should be rarely required.  
However, if it does become fouled, possibly indicated by a significant reduction in the gas  
pressure measured in the O3 cell, which would trigger a warning in the instrument, replace it as  
follows:  
1. Remove the orange cap from the top of the water drop-out filter.  
2. Located the membrane on the underside of the cap assembly and replace it.  
3. Tightly secure the orange cap back onto the water drop-out filter.  
9.9.  
Configuring the Analog Output  
The analog output can be configured for either 0-5V DC or 4-20mA operation. To change or  
verify the configuration of the analog output:  
1. Disconnect power from the M465L.  
2. Remove the six screws and the top cover (Rack Mount Configuration) or open front  
panel (NEMA Configuration.)  
3. Locate the Mainboard PCA (see Figure 9-1 or Figure 9-2.)  
4. Set the desired operation as shown in Figure 9-4.  
5. Re-Install the top cover or re-secure the front panel (NEMA Configuration.)

9.10. Cleaning Exterior Surfaces of the M465L  
If necessary, the front panel mask and keyboard of the M465L can be cleaned with a damp cloth.  
Do not attempt to clean any of the other surfaces of the instrument. Do not submerge any part of  
the instrument in water or cleaning solution.  
9.11. Boot Loader Operation  
The main function of a boot loader is to load or update the firmware to the microcontroller on the  
Printed Circuit Board (PCB) of an instrument. There are two types of boot loader setup:  
hardware and software, described in the following sections.  
NOTE  
When an external MODBUS host device is attempting to  
communicate with the instrument over the serial or Ethernet port  
while the instrument is starting up, the instrument may halt. In  
order to prevent the problem from occurring, ensure that there are  
no devices attempting communication with the instrument during  
start-up. Once the sign-on message is displayed on the front  
panel, it is safe to begin communications.

10.2. Troubleshooting Using Front Panel Status  
LED’s or Status Outputs  
The M465L has 4 front-panel status LED’s that reflect the current operating status of the  
monitor, and indicate fault conditions. There are also four relay Status Outputs on the rear panel  
(or internally in the NEMA configuration) that also reflect the state of these status LED’s. See  
Section 4.2.3 for more information on the Status Outputs.  
The Status LED’s are categorized into Critical and Non-Critical warnings. Critical warnings are  
those that would normally require immediately removing the monitor from service and repairing  
it. Non-critical warnings are those that indicate some maintenance would be useful, but not  
immediately required.

10.2.1. Sensor OK  
The Sensor OK LED indicates the status of the O3 sensor module in the monitor. The normal  
state of this LED (or Status Output) is On. If this LED remains off after the normal 20  
minute warm-up period, then a failure has occurred and the monitor should be removed from  
service and repaired.  
The most common cause of this warning is a failure of the UV Lamp. A UV Lamp  
Adjustment (See Section 9.4) should be attempted. If the UV Lamp cannot be adjusted to  
meet the specified values, then a UV Lamp Replacement should be performed (See Section  
9.5.)  
This warning can also be caused by a communications error with the sensor module. Inspect  
the two cables between the Mainboard PCA and Sensor Module for loose or intermittent  
connections (See Section 9.2 for monitor layout.) If no cable problem can be found, then the  
Sensor Module should be replaced.  
10.2.2. Invalid Reading  
The Invalid Reading LED indicates that the instrument is reading a value that cannot be  
represented properly on the analog output. Since the analog output is limited to 0-5V (or 4-  
20mA,) it cannot properly represent negative values, or values in excess of the full-scale  
range.  
If the monitor is consistently reading negative values, then a zero calibration should be  
performed, see Section 7.2.3.4.  
If the monitor is consistently reading values in excess of the full-scale range, then the range  
value should be adjusted higher. See Section 7.2.7 for details on setting the range value.  
10.2.3. Check Lamp  
The Check Lamp LED indicates that the UV Lamp intensity has dropped below 250mV, a  
level where UV Lamp Adjustment (See Section 9.4) should be made at the next convenient  
opportunity. Note that this is a non-critical warning and immediate service is not required.  
However if the UV Lamp intensity drops below 125mV, then the Sensor OK LED will also  
turn off, indicating that the monitor must be immediately serviced or taken off-line.  
10.2.4. Pneumatic Error  
The Pneumatic Error LED indicates that one of the pneumatic parameters, flow or pressure,  
has gone outside of normal ranges. Note that this is a non-critical warning and immediate  
service is not required. However if the Sensor OK LED turns off then the monitor must be  
immediately serviced or taken off line.  
The first step in troubleshooting a Pneumatic Error is determining which parameter has  
caused the warning. At the monitor front panel, navigate to the VIEW menu (See Section  
05509F DCN6409  
81  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Teledyne API Model 465L O Monitor Operation Manual

7.2.4.) Examine the Flow and Pressure values and compare them to the limits described in  
Table 10-1 and take appropriate action as described below.  
10.2.4.1. Pressure Too High  
The monitor inlet is being pressurized. The monitor inlet should be allowed to sample  
gas at ambient pressure. Disconnect all sample lines from the monitor and read the  
pressure again. If the value then drops to within the acceptable range, then one of the  
sample lines is at elevated pressure.  
If the inlet is being pressurized, then the design of the sample system should be reviewed  
and corrected. Contact Teledyne API customer service for assistance.  
10.2.4.2. Pressure Too Low  
Something may be restricting the flow through the monitor, causing the sample pump to  
pull a vacuum on the sensor module. First, unplug the sample pump power plug on the  
Mainboard PCA and observe the pressure reading. If the pressure reading is still too low,  
then likely there is a problem with the pressure sensor on the Sensor Module and the  
Sensor Module should be replaced. Next reconnect the pump and disconnect all sample  
lines from the monitor and see if the pressure increases to normal levels. If it does, then  
the problem is somewhere in the sampling system external to the monitor. If the pressure  
is still below the limit with the sample lines removed, then there is a restriction in the  
pneumatics of the monitor upstream of the sensor assembly. The most likely cause is a  
plugged particulate filter. Disconnect the outlet fitting on the sample filter and observe  
the pressure. If it returns to normal levels then the restriction is in the particulate filter or  
inlet manifold assembly (multi-stream configurations only.) Replace particulate filter per  
Section 9.3.

11. CALIBRATION  
11.1. Factory Calibration  
The Model 465 is calibrated to NIST traceable standards on the 0-1 ppm range prior to shipment.  
A calibration certificate for your instrument can be purchased from Teledyne API if required.  
Teledyne API also recommends that the Model 465 be re-calibrated once a year. Teledyne API  
can provide NIST traceable calibration services at our factory or on-site. Please contact our  
Customer Service department for details on these services.  
11.2. Zero Calibration  
A zero calibration can be easily performed in the field, and Teledyne API recommends that this  
be done at least annually. See Section 7.2.3.4 for details on performing a zero calibration.
