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 465L uses a
mercury lamp constructed so 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/Io. This ratio forms the basis for the calculation of the ozone
concentration.
The Beer-Lambert equation, shown below, calculates the concentration of ozone
from the ratio of light intensities.
109

CO3
29.92inHg
273
o
ln
o
Where:
I = Intensity of light passed through the sample
Io = Intensity of light through sample free of ozone
= absorption coefficient

= path length
CO3 = concentration of ozone in ppb
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 308
cm-1 atm-1 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.

Teledyne API Model 465L O3 Monitor Manual

Teledyne API Model 465L O3 Monitor Operation Manual
The intensity of light is converted into a voltage by a high resolution A/D (analogto-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 465L 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 Io. Measurement of the Io every 2.5 seconds eliminates
instrument drift due to changing intensity of the lamp caused by aging and dirt.

2. Turn on the 465L by switching the switch on the left side of the rear panel, or
applying power to the monitor (NEMA configuration.) The front panel display
should light with a sequence of messages, including the instrument serial
number and software revision. (When the instrument first powers up, the display
will show ‘xxxx’, indicating that the instrument is in start-up mode, waiting for
the UV detector readings to stabilize).
3. After the start-up period, the instrument will begin displaying the ozone
concentration and the optional stream selector will begin operating, if installed.

4.3.1. 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)

05509G DCN6806
Teledyne API Model 465L O3 Monitor Operation Manual
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 tubing is available from Teledyne API (Part number 02639)
4.3.1.1. 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 at the end of this manual for
ordering information.
4.3.1.2. 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 465L options is shown in
Figure 4-5, followed by a description of each. Please contact the Teledyne API Sales
Department for additional information.

Teledyne API Model 465L O3 Monitor Instruction Manual
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 465L specifications:
The Response Time of an 465L 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 465L is equipped with
this option, the unit has been calibrated at the factory to compensate for any ozone
loss in the permeation dryer.

4.3.2. 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.

4.4.
Electrical I/O Connections
4.4.1. Location of I/O Connectors in the NEMA Configuration
In the NEMA configuration of the 465L, 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.
4.4.2. 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 465L 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.
4.4.3. 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:

4.4.4. 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.

4.4.5. 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.)

OPERATION
Front Panel Overview
The 465L 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 M465L. 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 465L. 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.
05509G DCN6806
Teledyne API Model 465L O3 Monitor Manual

Teledyne API Model 465L O3 Monitor Operation Manual
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 465L 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
No alarm active
Amber
‘HI’ alarm active
Red
‘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 nonlatching 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 nonlatching 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 465L 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.

7.2.2. Editing Numeric Values
At certain places in the menu structure the operator can edit numeric values. The
menu buttons behave somewhat differently when in this mode.
Press CFG to select a digit to edit. The selected digit will blink. Next press the
UP/DOWN arrows to increment/decrement the selected digit. Press CFG again to
select another digit. Pressing CFG at the last digit will wrap back to the first digit.
Once all the digits have been edited, press ENT to accept the new value.
To abort the editing process without changing the original value, press and hold the
CFG button until the display returns to the previous menu level.
Note that limit checking is enforced while editing values and changes that would
result in invalid values are ignored.

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 465L. 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 465L. 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 Technical Support 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 465L.
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.

Multi-Stream Operation
This section describes the operation of the Multi-Stream M465L 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 465L 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.

DIGITAL COMMUNICATIONS
Digital Communications Overview
The 465L 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 465L is available for download
from the TAPI website. Other TAPI software, such as APICom, does
not currently support communications with the 465L.

RS-232 Configuration
The RS-232 configuration is usually used when making a one-to-one connection
between the instrument and a single computer or PLC. The communications
protocol used for the RS-232 configuration is MODBUS RTU. For details on the
MODBUS RTU specification, please see http://www.modbus.org/.
With the instrument configured for RS-232, connection can be made to the DB-9
connector, labeled “RS232/485”, or to the three “COM” pins on the “General I/O”
connector. Only one of these connections should be used, the other must be left unconnected. Table 8-1 below details the pinouts of these two connectors:

RS-485 is commonly used for factory automation busses with a computer or PLC
acting as a master. The communications protocol used for the RS-485 configuration
is MODBUS RTU. For details on the MODBUS RTU specification, please see
http://www.modbus.org/.
With the instrument configured for RS-485, connection can be made to the DB-9

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 465L. This application is available for download here:
http://www.teledyne-api.com/software/
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 465L 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 465L 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 465L, enabling them to communicate.
8.5.2. Verifying Network Hardware Connection
With the 465L 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 465L 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 465L. 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.
Click the Assign IP icon.
If prompted, enter the hardware address (on the product label) and click Next.
Select Assign a specific IP address and click Next.
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.

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.

of these status LED’s. See Section 4.4.3 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 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 Technical Support 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 465L 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
465L 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.
