3.1 Electrical Installation

Series 6 pyrometers are powered by a voltage of 24 V DC nominal (possible range 18 to 30 V DC,
ripple < 0.5 V). It is important to ensure correct polarity when connecting the device to the
power supply.

To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used.
LumaSense offers connecting cables, which are not part of the standard scope of delivery. The
shield of the connecting cable has to be connected only on the pyrometer’s side. If the
connecting cable is extended, the shield of the extension also needs to be extended. The shield
must be open on the power supply side (switch board), to avoid ground loops.

The connecting cable has wires for the power supply, interface, analog output, external laser
switch, and external clear of maximum value storage via contact and 12 pin connector (see
Chapter 8, Reference numbers).The cable includes a short adapter cable with a 9-pin D-SUB
connector. This connector may be used in combination with the RS485 to USB adapter.

Warning: Follow common safety regulations for mains voltage (230 or 115 V AC) and
connecting additional devices operating with this mains voltage (e.g. transformers).
Touching mains voltage can be fatal. A non expert connection and mounting can
cause serious health or material damages.

Only qualified specialists are allowed to connect such devices to the mains voltage.

Once the instrument has been connected to the power supply, it is immediately ready for use.
Although it does not need to be warmed up, it does need to run for approximately 15 to 30
minutes before achieving full accuracy. The instrument can be switched off by interrupting the
power supply or unplugging the electrical connector.

3.2 Connecting the pyrometer to a PC

Controller

w

hite

The pyrometer is equipped with a RS485 serial interface. With the RS485, long transmission
distances can be realized and the transmission is, to a large extent, free of problems. The RS485
also allows several pyrometers to be connected in a bus system.

If a RS485 connection is not available at the PC, it can be accomplished using the RS485 to USB
connector. When using a RS485 to USB adapter, make sure that the adapter is fast enough to
receive the pyrometer’s answer to an instruction of the master. Most of the commonly used
adapters are too slow for fast measuring equipment, so it is recommended to use the
RS485 ó USB converter “USB nano“ (ref. no. 3 826 720).

3.2.1 Connecting to RS485 interface / baudrate

Half-duplex mode: A1 and A2 as
well as B1 and B2 are bridged in
the 12-pin round connector of
the connecting cable, to prevent
reflections due to long stubs. It
also safeguards against the
interruption of the RS485 Bus
system should a connecting plug
be pulled out. The master labels
mark the connections on the
RS485 converter. The maximum
transmission rate of the serial
interface in Baud (Bd) is
dependent on the length of the
cable. Values between 1200 and
115000 Bd may be set.
The baud rate has to be reduced by
50% when the transmission distance is doubled (see 4.7 Baud rate). Typical cable length for
19200 Bd is 2 km.

3.2.2 Connecting additional analyzing devices

Additional analyzing instruments, such as a LED digital display instrument, need to be connected
to a power supply and the analog outputs from the pyrometer. Other instruments, like a
controller or printer, can be connected to the display in series as shown below (total load of
resistance max. 500 Ohm).

3.3 Sighting

For exact measurement of the object temperature the pyrometer must be aligned correctly onto
the object. Pyrometers without sighting are normally used for measurement of bigger objects
for which exact alignment is not absolutely necessary. These pyrometers can be aligned only
with the thermal method.

3.3.1 Thermal Alignment

When measuring a hot object in front of a cooler background, it is usually sufficient to align the
pyrometer with the hottest spot on the object to achieve the highest temperature reading.

3.4 Optics

The pyrometer is equipped ex works with the following optics. The spot size will enlarge in any
other distance (shorter or longer). Please notice that the measuring object must be at least as
big as the spot size. The following drawing shows the size of the spot in mm in dependence of
the measuring distance. Values between the mentioned data can be calculated by interpolation.
The spot size for measuring distance 0 is the aperture diameter of the optics.

Note: Please note that the optical profiles show nominal dimensions. The spot size
diameter or the focal distance may be slightly different due to lens tolerances.

Note: The InfraWin program includes a Spot size calculator that roughly estimates the
unknown values. The values represented here are for reference purposes.

Spot sizes for intermediate distances that are not shown on the optical profiles, may be
calculated using the following formula:

IN 6/78-L Operating Manual Controls and Connections · 15

3.5 Avoiding reading errors caused by faulty assembly

To avoid reading errors, please note the following points when mounting the pyrometer:

1. The diameter of the measuring object cannot be smaller than the pyrometer’s spot size (see
section 3.4, Optics).

2. A source of radiation behind or around the measuring object can influence the result. If the
object is transparent or partly transparent, another material behind the object could
transmit its radiation to the pyrometer as well. In this case, the location of the pyrometer
should be changed, or, if the background radiation remains constant it can be compensated
for by changing the emissivity setting respectively.

3. Please take into account that radiation from other hot surfaces around the measured object
can be reflected by the target and influence the result. If the measured object has a low
emissivity, the temperature measured will be mainly that from the reflected object - not
from the intended measured object itself. To prevent ambient radiation from reaching the
spot area, a mounting tube should be used. The mounting tube should be placed as near as
possible to the measured object so that the tube’s shadow blocks out all the ambient
radiation from the side. Consider whether 4.9 Ambient temperature compensating
applies to the measurement application.

Settings:

Before using the pyrometer some basic settings should be taken. The basic settings can
be done via interface and software InfraWin.

Settings via serial interface: The pyrometer is equipped with a serial interface RS485
which can be used for connection to a PC. With the standard software InfraWin (or a self written
communication software) the following settings can be done, to use this functions, emissivity,
transmittance, exposure time, analog output, maximum value storage, minimum value storage,
reading of the instrument’s internal temperature, setting of an address for bus control with
RS485 interface, setting of the baud rate, function for compensating of the off-set of the
ambient temperature). Additionally, InfraWin enables the temperature display and analysis.

4.2 Emissivity ε

For a correct measurement it is necessary to adjust the emissivity. This
emissivity is the relationship between the emission of a real object and the
emission of a black body radiation source (this is an object which absorbs all
incoming rays and has an emissivity of 100%) at the same temperature.
Different materials have different emissivities ranging between 0% and
100% (settings at the pyrometer between 10 and 125%). Additionally the
emissivity is depending on the surface condition of the material, the spectral
range of the pyrometer and the measuring temperature. The emissivity setting of the pyrometer
has to be adjusted accordingly. Typical emissivity value of glass is listed below. The tolerance of
the emissivity value for each material is mainly dependent on the surface conditions. Rough
surfaces have higher emissivities.

Note: The minimum emissivity setting for the pyrometer is 10%.

One way to determine an accurate emissivity value for a material is to make a comparison

Settings:

Settings:

measurement as follows: If possible, coat a portion of the object with dull black paint or carbon
soot. Paint and carbon soot have high emissivity (95%) and take on the same temperature as the
object. Measure the temperature of the painted area with the emissivity control set to 95%.
Then measure the temperature of an adjacent unpainted area of the object and adjust the
emissivity until the pyrometer displays the same temperature.

4.3 Transmittance t

Measurements through windows slightly attenuates the measuring signal (due to the
transmittance). To obtain correct measuring results, the transmission of the window must be
compensated. Alternatively, the emissivity ε can be adapted.

4.4 Analog output

The analog output has to be selected according to the signal input of the
connected instrument (controller, PLC, etc.).

4.5 Maximum / minimum value storage

If the maximum value storage is switched on, the last highest temperature
value will always be displayed and stored. The minimum value storage saves
the lowest measurement taken during a reading. The storage has to be
cleared at regular intervals and be replaced with a new and actual value.

This feature is particularly useful when fluctuating object temperatures cause
the display or the analog outputs to change too rapidly, or the pyrometer is
not constantly viewing an object to be measured. In addition, it may also be
beneficial to periodically delete and reset the stored maximum values.

The following settings are possible:

Off:

0.1...25 s:

extern:

The max. value storage is switched off and only momentary values are measured.

If any clear time between 0.1 s and 25 s is set (0.1 s, 0.25 s, 0.5 s, 1 s, 5 s, 25 s), the
maximum value is estimated and held in double storage mode. After the
entered time the storage will be deleted.

The external clearing can be activated and used within your own software using
the clear command “lx” (see Chapter 7, Data format UPP). In this case, the
storage operates only in single storage because only a single deletion mechanism
is used.

auto: The auto mode is used for discontinuous measuring tasks. For example, objects

are transported on a conveyer belt and pass the measuring beam of the
pyrometer for only a few seconds. In this case, the maximum value for each object
has to be indicated. In this mode the maximum value is stored until a new hot
object appears in the measuring beam. The temperature which has to be
recognized as hot is defined by the low limit of the adjusted sub range. The
stored maximum value will be deleted when the temperature of the new hot
object exceeds the low limit from of the sub range by 1% or at least 2 °C. If a
lower limit is not entered, the maximum value storage will be deleted whenever
the lower level of the full measuring range has been exceeded.

Depending upon which setting is selected, the maximum value storage will either
work in single storage mode or in double storage mode:

Single storage: The single storage mode is used when you want to reset the

stored value using your own software with the clear command “lx”. This
mode allows a new value to be established after each impulse from the reset
signal.

Double storage: The double storage mode is automatically selected when
entering the reset intervals using the PC interface. This mode utilizes two
memories in which the highest measured value is held and is deleted
alternately in the set time interval (clear time). The other memory retains the
maximum value throughout the next time interval. Disadvantages of
fluctuations in the display with the clock frequency are thereby eliminated.

Note: In the command structure, the maximum storage comes after the exposure
time. This results in:

· clear time £ the adjusted response time is useless

· clear times must be at least 3 times longer than the response time

· only maxima with full maximum value can be recorded, which appear at

least 3 times longer than the response time.

4.6 Subrange

You have the opportunity to choose a subrange (minimum span 51 °C) within the basic
measuring range of the pyrometer. This subrange corresponds to the analog output. Reduction
of the temperature range increases the accuracy of the analog output.

Also when setting the subrange, it is possible to fulfill the requirements of the “auto” clear
mode of the maximum value storage (see 4.5 Maximum/minimum value storage).

4.7 Baud Rate

The highest permissible transmission rate of the serial interface in Baud (Bd)
is dependent on the length of the cable. A standard cable length with RS485
is 2 km at 19200 baud. The baud rate is reduced by 50% if the transmission
distance is doubled.

1200 bd

115000 bd

4.8 Address

When connecting several pyrometers to one serial interface with RS485, it is
necessary for each instrument to have its own device address for
communication purposes. First, it is necessary to connect each instrument
separately to give it an address. After that, all instruments can be connected
and addressed individually.

Note: Only via own communication program with interface command (not
possible with InfraWin, because InfraWin automatically detects a connected
pyrometer): If parameters should be changed simultaneously on all pyrometers, the
global Address 98 can be used. This allows you to program all pyrometers at the
same time, regardless of the addresses that have already been assigned. If the address
of a pyrometer is unknown, it is possible to communicate with it using the global
Address 99 (connect only one pyrometer).

4.9 Ambient temperature compensation

Each object has an emissivity e (maximum 100%). If the measured object is not transparent and
has an emissivity of less than 100% (as in most cases), a portion of the resulting radiation will be

IN 6/78-L Operating Manual Settings / parameter descriptions · 19

reflected. For bright, smooth surfaces, such as mirrors, the reflected radiation is more focused;

Settings:

on rough, harsh surfaces it is diffuse. The rate of diffuse reflection is, in this case (100% - e).

If the measured object’s temperature is the same as the ambient temperature (this is most often
the case), you only need to set the emissivity on the pyrometer (when using the InfraWin
program the off-set compensation for the ambient temperature must be in “auto“. If the object
to be measured is in an oven, where the temperature is higher than the ambient temperature, a
portion of the radiation, corresponding to the rate of diffuse reflection, will be “reflected“ by
the measured object to the pyrometer, resulting in an inaccurate reading (the reading will be
too high due to the oven temperature).

In this case, it makes sense to activate the off-set compensation for the ambient temperature (in
the parameter window of the InfraWin program: Compensating for the off-set of the ambient
temperature switched to “man.“ (= manual) and then enter the ambient temperature value (in
this case, the oven temperature) in the corresponding field. The program also makes a
compensation calculation in order to display the correct temperature.

Be aware that the accuracy of such a correction is highly dependent on accuracy of the emissivity
value that was set. The off-set compensation for the ambient temperature uses the rate of

diffuse reflection when performing its calculation. If you alter the emissivity (e), you are also
altering the rate of diffuse reflection (100% – e) and in turn, the displayed temperature. The

following observation shows how a faulty emissivity reading in conjunction with the
compensation for the ambient temperature affects results:

Entry of e = 91% instead of 92% indicates:
A relative change in emissivity of 1.1 %.
Likewise the assumed rate of reflection changes from 8 % to 9 %.
This results in a relative increase in reflection of 12.5 %.

This change also impacts the displayed result, thereby causing a fairly inaccurate compensation
calculation. For hot environments, this calculation will probably serve as a much more accurate
assessment than the standard calculation, which assumes that the ambient temperature is the
same as that of the object measured.

4.10 Wait time t

Using a pyrometer with RS485 it is possible that the connection is not fast
enough to receive the pyrometer’s answer to an instruction of the master. In
this case a wait time can be set to slow down the data transfer (e.g.: tw = 02
at a baud rate 9600 means await time of 2/9600 sec).

Note: The pyrometer enters a waiting period after certain commands and may not
respond right away because some commands have an internal processing time of up
to 3 ms.

4.11 Internal Temperature of the Pyrometer

The internal temperature of the pyrometer can be read via interface. It is a few degrees above
the ambient temperature due to the heat generated by the pyrometer electronics.

5 Software InfraWin

The operating and analyzing InfraWin software is included with delivery of the pyrometer. In
addition to allowing you to make parameter adjustments, the InfraWin software also provides
temperature indication, data logging, and measurement analysis features.

This section gives an overview about the functions of the software. It also provides a description
of the individual icons found in the program's help menu. Click on the F1 button after loading
InfraWin or click on the ? in the menu bar.

The following descriptions refer to software InfraWin version 5.0. The latest version is available
for free as download from the homepage www.lumasenseinc.com.

5.1 Connecting the pyrometer to a PC

5.4 Basic settings

All preset values for the

device can be displayed
and modified, if necessary under
the Devices/Parameters window.
This window contains the
parameter settings described in
Chapter 4, Parameters.

Changing an existing pyrometer
setting can be accomplished by
typing a value in an input box or
by selecting a preset value from
the list field. Choose the correct
settings for your application
from the displayed options.

Once a value is changed, it is
transferred to the pyrometer
immediately.

Clicking on the Test icon will
open a window that allows you
to directly communicate with the
pyrometer using the UPP
(Universal Pyrometer Protocol)
Data Format commands. See
Chapter 7 for information on
working with the UPP Data
Format commands.

After entering an interface
command (00 is the adjusted
address ex works, ms is the
command reading
temperature value) and
clicking on Send, the window
shown to the right will be
opened.

This window already shows the answer of the pyrometer in 1/10°. The actual temperature
reading is 399.0 °C.

Len indicates the length of the answered data string, incl. Carriage Return (Chr(13)).

In the lower part of the window the connection with the preset baud rate can be checked. Here
the command was sent 100 times with 19200 baud. It has taken 0.937 seconds without
transmission errors.

IN 6/78-L Operating Manual Software InfraWin · 22

Emi: AutoFind: If the true temperature of the measured object is known, you can calculate the

emissivity of the measured object using the Emi: AutoFind function:

A measured temperature is displayed with the
current set emissivity (in this example 100%) (here:

416.1 °C).

If you press Emi: Autofind a window will open
which allows you to enter the "true" temperature
(here 430 °C).

Once the temperature entry has been entered and
confirmed with Calculate, InfraWin will then
calculate the emissivity which occurs with the new
temperature (here 97.3%). This is displayed
immediately and can be used for further
temperature measurement.

5.5 Measurement online trend

The Measurement online
trend window displays:

· temperature as graphical diagram

· internal temperature of the instrument

· current temperature

· the quantity of the measured values

and file size of the current

measurement.

The example shows a sample reading over the
period of approximately 15 seconds with a
temperature range between 400 and 800 °C. The final temperature (at the end of the reading) is
431 °C.

The Mark Zone button allows you to color mark a temperature range for easier recognition.

The Threshold button allows you to set a temperature value as a baseline to prevent recording
values above or below the baseline temperature. This allows you to keep the output file size
small.

The Scaling Trend button allows you to scale temperature trend view.

IN 6/78-L Operating Manual Software InfraWin · 23

Note: The measuring values of “measurement online trend” are automatically saved

as "standard.i12". Should you need to edit the data later, you need to save the file as
another .i12-file because old values are over-written when a new measurement is
taken.

Files from older program versions (.i10-files) can be opened and saved as .i12.

5.6 Listing (analyzing)

For analyzing

the measured
values in this field, all measured
data appears in a numeric list.

The column between time and
temperature provides a time
resolution of milliseconds. The
value specifies the time in seconds
after midnight (0:00 h). The amount
of data depends on the frequency
that readings were taken (settings
at 10.9 PC sampling rates). As the
amount of data increases, so does
the amount of storage space
required to save it. In order to save room, all .i12 data files are stored by a binary code.

5.7 Output .TXT file (analyzing)

The same file as under Output listing may be converted into a text file and
can be easily opened, for example with EXCEL. With the standard import

settings, EXCEL automatically formats the columns accordingly (with tabs as separators).

5.8 Trend output (analyzing)

The graph’s curve depicts the
temperature change over time
within the specified temperature
range.

Additionally, other information
appears in this window; such as
recorded time (x-axis) and
temperature in degrees (y-axis) as
well as the time and temperature
at the vertical cursor line which can
be dragged with the mouse.

Selecting the Trend output initially
causes all the saved data to be
displayed.

If the data exceeds an amount that can be reasonably represented, you may “Zoom“ in on a
partial segment using the mouse (such as the segment represented in the example). Under
“Total” you can return to the representation of the entire curve.

IN 6/78-L Operating Manual Software InfraWin · 24

Note: The last reading is saved in the standard.i12 file and automatically appears in

this form upon opening Listing or Trend output.

Selecting file open with another file, the previous file will be overwritten and re­placed by the standard.i12 file.

5.9 PC sampling rate (time interval between two

measurements)

This function sets a time interval. After

each interval, one measured value is
stored on the PC. Longer time intervals will result in
creating smaller stored file sizes. This function is mainly
used for long term measurements

5.10 Spot size calculator

The InfraWin Spot Size Calculator

calculates the data for the non­focused regions. To calculate data, enter the values
of aperture D, focused measurement distance a,
and focused measuring field diameter M as found
in the documentation relating to the optics
supplied with your specific pyrometer.

After entering the aperture and the main spot size,
the input of interim values calculates spot sizes in
different measuring distances of the fixed optics.

5.11 Search I/O Module

The I/O Module allows

accessories to connect to
the software and is used to trigger
measurement externally or to send a signal
(like a relay) under certain conditions.

Protocol)

Via interface and suitable communication software or via Test function of the InfraWin
software (see Section 5.4 Basic settings) commands can be exchanged directly with the
pyrometer.

The data exchange occurs in ASCII format with the following transmission parameters:

The data format is: 8 data bits, 1 stop bit, even parity (8,1,e).

The device responds to the entry of a command with: output (e.g. the measuring value) + CR
(Carriage Return, ASCII 13), to pure entry commands with ok + CR.

Every command starts with the 2-digit device address AA (e.g. "00"). This is followed by 2 small
command letters (e.g. "em" for level of emissivity e), finished with CR.

This is followed, if necessary for that command, by the ASCII parameter "X". If this parameter
"X" is omitted, then the device resets with the current parameter.

A ? after the small command letters answers with the respective settings (only at setting
commands, not at enquiry commands).

Example: Entry: “00em“ + <CR>

The emissivity setting (e) of the device with the address 00 is returned.

Answer: “0970“ + <CR> means Emissivity = 0.97 or 97.0%

9 Troubleshooting

Before sending the pyrometer for repair, try to find the error and to solve the problem with the
help of the following list.

Temperature indication too low

· Incorrect alignment of the pyrometer with the object

Þ Realign to achieve the maximum temperature signal(see 3.3)

· Measuring object smaller than spot size

Þ check measuring distance, smallest spot size is at nominal measuring distance (see 3.4)

· Measuring object is not always in the measuring spot of the pyrometer

Þ Use maximum value storage (see 4.5)

· Emissivity set too high

Þ Set lower correct emissivity corresponding to the material (see 4.2)

· Lens contaminated

Þ Clean lens carefully (see 6.2)

Temperature indication too high

· Emissivity set too low

Þ Set lower correct emissivity corresponding to the material (see 4.2)

· The measurement is influenced by reflections of hot machine parts

Þ Use mechanical construction to avoid the influence of the interfering radiation

Measuring errors

· Indicated temperature is decreasing during the use of the pyrometer, contamination of the

lens

Þ Clean lens. Recommendation: use of air purge (see 3.3)

· Indicated temperature is decreasing during the use of the pyrometer, although the air purge

unit is used. Probably compressed air is not clean or air failed

Þ Clean the lens and use clean, dry and oil free compressed air

· Air contamination in the sighting path between pyrometer and object

Þ Change position of the pyrometer with a clean sighting path (if necessary use a ratio

pyrometer)

· RF-interferences

Þ Correct the connection of the cable shield (see 3.1)

· Instrument overheated

Þ Use cooling jacket with air or water cooling (see 2.5)

· Temperature Indication is fluctuating, probably caused by changing emissivity

Þ Wrong pyrometer type, use of ratio pyrometer recommended
