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 O3 molecule. The Model 465 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.

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.

05509F DCN6409 19

Teledyne API Model 465L O3 Monitor Operation Manual

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 Io. Measurement of the Io every 2.5
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”.

05509F DCN6409 21

Teledyne API Model 465L O3 Monitor Operation Manual

Figure 4-1: NEMA AC Power Connection to Monitor

6. Connect the power cord to an appropriate power outlet (see the serial number tag for

correct voltage and frequency).

CAUTION

Verify that the instrument is set up for proper line voltage and
frequency. Observe local electrical codes when connecting power to the
monitor.

7. Turn on the M465L 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)..

8. After the start-up period, the instrument will begin displaying the ozone concentration

and the optional stream selector will begin operating, if installed.

Teledyne API Model 465L O3 Monitor Operation Manual

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)

Teledyne API Model 465L O3 Monitor Operation Manual

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.

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 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:

05509F DCN6409 29

Teledyne API Model 465L O3 Monitor Operation Manual

Figure 4-8: Status Output Schematic

The outputs are defined as follows:

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.

Teledyne API Model 465L O3 Monitor Operation Manual

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.)

Each available stream has a set of 3 relays providing the following information:

6. OPTIONS

Following are descriptions of options available for the M465L.

6.1. Stream Selector (3 or 6 Stream)

This option allows the M465 to measure ozone at up to six different sampling points by using an
internal stream selector. 3 or 6 channel stream selectors are available. This option includes
digital outputs for HI and HI-HI alarms and a channel ID for each channel in the stream selector.

6.2. Disposable Sample Inlet Filters

This option consists of 50 disposable filters for installation at the inlet end of all sample lines.

6.3. Rack Mount Slides

Rack mount slides can be attached to the sides of the instrument, allowing it to slide completely
out of a RETMA rack, facilitating maintenance activities.

6.4. Electronic Flowmeter

The M465 can be fitted with an internal electronic flowmeter that enables the instrument to
display the flow digitally on the front panel and provides a Pneumatic Error if the flow is outside
its normal limits.

6.5. Sample Conditioner

For humid environments where there is risk of water condensation in the sample lines, this
option serves to filter out liquid and particulates and includes a permeation gas dryer as well. For
details, see “Sample Conditioner” in Section 4.1.1.2.

6.6. Permeation Gas Dryer

This option removes water vapor from the sample stream in environments where humidity is a
concern but where condensation is not a factor. For details, see “Permeation Gas Dryer” in
Section 4.1.1.2.

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-of­measure 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.

05509F DCN6409 39

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 three­channel 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 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 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 non­latching operation.

See Sections 7.2.7, 4.2.4, and 4.2.5 for additional details on concentration alarms.

40 05509F DCN6409

Teledyne API Model 465L O3 Monitor Operation Manual

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:

Table 7-2: Status LED’s

Status LED Normal State

Sensor OK ON
Invalid Reading OFF
Check Lamp OFF
Pneumatic Error OFF

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.

Teledyne API Model 465L O3 Monitor Operation Manual

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.

7.2.3.3. Memory Reset

This function is currently disabled.

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.

05509F DCN6409 47

Teledyne API Model 465L O3 Monitor Operation Manual

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 30­second 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.

8.3. 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 un-connected. Table 8-1 below details
the pinouts of these two connectors:

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:

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 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.”

Table 8-5: Ethernet LED Definitions

Color Meaning Color Meaning

Off No Link Off No Activity
Amber 10 Mbps Connection Amber Half-Duplex
Green 100 Mbps Connection Green Full-Duplex

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

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.

DeviceInstaller window; a list

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.

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.

74 05509F DCN6409

Teledyne API Model 465L O3 Monitor Operation Manual

9.11.1. Boot Loader – Hardware Setup

Verify that the instrument is configured for an RS-232 connection. See Section 8.2 for details on
changing the COM port configuration. The instrument can be connected to the PC COM port
using a 9-pin serial cable (TAPI P/N WR77).

9.11.2. Boot Loader – Software Setup

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 4­20mA,) 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

Teledyne API Model 465L O3 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.
