3.1.2 Switching Outputs
The switching outputs are used to detect if a certain temperature
threshold is exceeded or falling below.
The output logic is invertible, see under 5.2 Setting window in the
SensorTools Software).
3.1.3 Serial Interface RS232 or RS485
Polaris are available with RS232 or RS485 interface, the built-in version is to find on the device label.
The serial interface is used for digital communication of the device with another computer, for example a
PC for data transmission to the software SensorTools.
The maximum transmission speed (in Baud) is limited by the cable length, it is halved with each doubling of the transmission path.
RS232: about 7 m cable length with 19.2 Bd. Adjustable are values from 1.2 and 57.6 kBd.
RS485: about 2 km with 19.2 kBd. Adjustable are values between 1.2 and 57.6 kBd.
Connecting one Polaris
via RS232 or RS485:
In a short RS232 or RS485 connection to the master (computer receiving the data), the Polaris is
connected directly as a point-to-point connection
with the master.
Connecting several Polaris via RS485:
For a reflection-free operation with longer cables, pay attention to the correct cable termination. Termination at the physical bus is on front and rear.
Master at the
beginning:
Master in the
middle:
When operating multiple devices (up to 32 are possible), each device needs to assign its own address
(directly on the device or via software SensorTools), under which it can be addressed later. For this
purpose, initially, each device must be connected individually and provided with an address (00-97). After that, all devices can be connected.
If specific parameters for all devices should be changed simultaneously, the global address 98 is used
(there is no response from the device). If the address of a device is unknown, you have the opportunity
to address each device independently of the set address with the global address 99 (connect only one
device).

3.1.3.1 Interface Converter (Accessory)
Using an interface converter DK3000 or DK4000 (RS232USB or RS485USB) is a quick and easy
way to connect the infrared switch to a PC (see 6.4 Accessories). Via the sub-D connector this is simply connected to the cable AK31.
Depending on the operating system, suitable drivers are installed automatically or can be found on the
CD supplied with the software SensorTools in the directory Drivers FTDI_USB_COM, or after installing SensorTools in the installation directory (updated driver for Windows from the FTDI website:
http://www.ftdichip.com/Drivers/VCP.htm).
4 Mechanical Installation
4.1 Mounting
Note that the installation lecation is free of vibrations. If necessary, helps the use of rubber absorbers
when mounting.
The device can be mounted in a drilling hole of 41 mm Ø and fixed with the included nuts (M40x1.5).
For easy installation a mounting angle is available as accessory (see 6.4 Accessories).
4.2 Ambient Temperature
Polaris switches are designed for ambient temperatures between 0 and 70°C. Operation outside this
temperature leads to incorrect measurements and may damage the unit.
To comply with the permitted ambient temperature, sufficient distance from the (hot) object to detect is
observed.
To prevent laser targeting light overheating, the targeting light is deactivated at a device temperature
from 55°C. Below that temperature it can be used again
Accessory: The use in ambient temperatures outside the permissible ambient temperature is possible
with an additional cooling housing (see 6.4 Accessories).
4.3 Alignment onto the Measuring Object
To detect the temperature correctly, the infrared switch must be aligned properly to the measuring object. In the focus point of the optics (focus distance) the spot size diameter is the smallest. Also measurements in the defocused area can be done to determine the average temperature of a bigger spot. If
the target under measurement is smaller than the spot size produced by the lens, the colder or warmer
border is also measured and results in a lower or higher temperature.
The optical path between infrared switch and the target must be free of interfering objects and va-
pors, fumes or dust (if necessary, use air purge or sight tube).
A viewing window between Polaris and the measured
object should have constant transmission properties in
the spectral range of the Polaris (e.g. BK7 crown
glass). The transmission loss must be compensated
by correction of the emissivity.
If the target is smaller than the spot size, there will be
measuring errors because background temperatures
go with the measurement.
Spot size smaller than measured object, measurement OK

Spot size larger than measured
object, enter fill factor, observe

4.3.1 Alignment with the Laser Targeting Light
The laser targeting light is a conical red laser beam with
the largest diameter directly at the lens and the smallest
and sharpest in the focused distance, i.e. at the point
where the measuring field is the smallest.
The focus distance (=measuring distance at the smallest
spot size) is easy to find where the laser dot is the smallest.
INFO: The size of the laser point does not match to the spot size, spot sizes are given in the
spot size tables (see 4.5)
CAUTION, Laser Radiation, Laser Class 2:
Never look into the direct or reflected laser beam.
Do not point the laser to anyone.
If laser radiation hits the eye, the eyes must be intentionally closed and the head immedi-
ately moved out of the beam.
Turn on / off via the targeting light button on the rear side or via Sen-
sorTols software (see 5.2).
The targeting lightwill automatically switched off after 2 minutes (if not
switched off manually).
INFO: The laser targeting light is turned off at a device
temperature above 55°C.
If the targeting light does not turn on, probably the device's
internal temperature is too high. In this case, the installation
place should be checked (excessive heat radiated from the
measuring object). When temperature falls below 55°C the
laser is working again.
4.4 Setting the Measuring / Focus Distance
The focal distance is the distance at which the optics achieves its smallest spot size. In most cases, this
distance is also the required measuring distance.
With the focusable optics the focus distance can be changed continuously within a predetermined range
(see 4.5 Spot size tables), so the smallest possible spot size is always achieved.
Loosen locking screws (allen key 1.5 mm)
Adjust measuring distance by turning the optics in or out un-
til the measuring distance is found
- Optics screwed out: short measuring distances
- Optics screwed in: long measuring distances
Fix locking screws (hand-screwed).

4.5 Spot Size Tables
The following tables show the optical data of the different device types. The values in the tables are exemplary, intermediate measurement distances must be determined by interpolation. If the measuring
distance differs from the adjusted or specified, a measurement is also possible, but the spot size
changes (usually it is larger, see 4.5.1 Calculation of the Spot Size Diameter outside the Focused
Distance). The measuring distances are specified from lens front.

4.5.1 Calculation of the Spot Size Diameter outside the Focused Distance
The spt size diameter determines the area on the measurement object from which 90% of the temperature radiation is detected by the pyrometer; therefore the spot size tables specify spot sizes for different
measuring distances (or focused distances).
For calculating intermediate values in front of and behind the focused measuring distance, the following
formula can be used or the Spot size calculator integrated in SensorTools (under 5.2):
a Focused distance
M Spot size diameter in the focused measuring
distance
a1 Measuring distance longer than focused meas-
uring distance
M1 Resulting spot size on measuring distance a1
a2 Measuring distance shorter than focused
measuring distance
M2 Resulting spot size on measuring distance a

4.6 Parameters / Settings
4.6.1 Emissivity ε
The emissivity indicates the radiation
capacity of an object to be measured
relative to a calibration source with the
same temperature. To obtain correct
readings, the emissivity must be taken
into account in the measurement and
adapted for the respective measuring
material on the infrared switch. Each
material has a max. emissivity of 1.00
(=100%) which can be set.
In principle applies: to measure metals
in a short-wavelength spectral range as
possible, as here the emissivity is higher than in the long-wave range.
The specified values are guide values,
which were determined in the laboratory
and confirmed in application-oriented
measurements. They can vary due to
material-dependent conditions, as in
metals additionally to the surface texture alloy components play an important
role for the emissivity.
Is a range given, this is related to dif-
ferences in the nature of the surface
from smooth to rough, rough surfaces
have higher emissivities (for determining the correct emissivity also a
comparison measurement can be
performed with a thermocouple).
“n.s.“ means that no values exist for
this wavelength range (not specified),
e.g. because a reasonable measurement in this wavelength or temperature range is not possible.
The emissivities with "shiny" refer to
applications that are performed under
an inert gas or in a vacuum.

4.6.2 Response Time t90
The response time specifies the time that an infrared measuring device requires to track 90% of a
sudden temperature change on the signal output.
The response time depends on the requirements of the respective measuring task and can be adjusted.
If a short response time is selected, the temperature measurement follows the actual temperature
curve accurately. Short setting thus allowing the detection of briefly occurring temperature peaks,
which occur especially in fast heating processes or fast moving samples.
At longer response times, the measurement signal is smoothed and average values for temperature
fluctuations are formed caused by the inertial measurement.
4.6.3 Simulate a Switching Temperature
The switching outputs can be checked by simulating a switching temperature.
4.6.4 Baud Rate
The baud rate can be set between 1.2 and 57.6 kBd.
4.6.5 Address
In bus operation with RS485, an address between 00 and 97 can be assigned.
4.6.6 Interface Delay (Answer Delay)
During operation of the infrared switch via RS485, it may happen that the connection is not fast enough
to detect the response of the infrared switch to a command from the master, e.g. because the line is still
busy with sending before receiving. This sometimes occurs in older PCs or interface adapters or by
slow switching times of interface adapters and manifests itself in transmission errors of interface commands, so errors when parameters are changed or of measured values transmission.
In this case a delay for delaying the data transfer can be entered, the value specifies the main circulating time and can be set from 00-20. The transmission of commands to the connected device is thus
somewhat delayed, but it can work with existing peripherals.

5 Configuring via SensorTools Software
5.1 Program Start
Starting the software opens
the main window of the program. The Polaris is not connected automatically.
Since the Polaris is not a
measuring instrument, the
temperature reading functions in the main window of SensorTools are not functional.
5.1.1 Connecting the Polaris
For successful communication with the Polaris it has to be connected first.
Select the computer’s com port the device is connected to. Also a COM port must be
selected when connecting via an USB converter.
Press the search button if the com port is unknown. The device will be connected
automatically if the port is found.
Press the connect button to connect the device to the software. All device settings will
be read out and displayed in the software.
The button changes to “Disconnect” when connected. Click to disconnect.
The status line informs about device and connection status.
5.2 Setting Window
The setting window will appear as soon as the connection
is established.
The response time t90 (see 4.6.2) can be adapted to the
measurement conditions.
Selecting "Minimal" the Polaris works with the shortest
possible devices response time of 4 ms.
Under "User definded", times up to 10 s can be entered.
The Emissivity (see 4.6.1) is used for adaptations to the
material surface properties.
Limit switches:
- Limit value: Activates the corresponding output (Port)
at the entered limit value.
- Hysteresis: The hysteresis is the value at how many
degree below the limit value the output is switched
back.
- Logic: The state of the digital outputs can be set:
- NO (normally open): outputs have in active state 24
volts (precicely the power supply voltage, output
max. 30 mA) to the pins and in inactive state 0 V.
- NC (normally closed): outputs have in active state 0 volts to the pins and in inactive state 24 V
(precicely the power supply voltage, output max. 30 mA)
Laser targeting light: turns on and off the laser targeting light.
CAUTION, Laser Radiation, Laser Class 2:
Never look into the direct or reflected laser beam.
Do not point the laser to anyone.
If laser radiation hits the eye, the eyes must be intentionally closed and the head im-
mediately moved out of the beam.

CAUTION, switch off supply voltage.
Before beginning any maintenance, switch off power supply or pull connector on the Polaris to prevent injury by accidentally activated laser targeting light!
7.1 Cleaning
Clean the lens with a soft cloth and a little alcohol or acetone. Use only high-purity acetone to avoid residues.
The objective lens is not
to clean with solvents that contain acid
immerse in water or other liquids to clean
7.2 Calibration
To obtain the measurement accuracy, we recommend to re-calibrate the Polaris at Sensortherm periodically (annually) with the help of calibration sources.
8 Communication via Serial Interface / Interface Commands
Interface commands are used to communicate directly with a Sensortherm device. Commands can be
used to write an own access control or can be entered in the terminal field of the software SensorTools
(in the main window in the tab “miscellaneous”) or entered via a terminal software. Data is exchanged in
ASCII format with the following transmission parameters: 8 bit, 1 stop bit, even parity (8,1,e).
Command structure:
For successful communication the following sequence of a command is used:
Device Address - Command - Parameter
Device address: all interface commands are starting with the 2-digit device address (exception: in
the terminal field of the SensorTools software no address is required). In factory setting the device
address is 00 but can be change per command.
Device addresses from 00 to 99 are valid but 98 and 99 are with special functions. The global address 99 can be used to communicate with every device, independent of the set address. This allows
communication with devices which have unknown addresses. The address 98 is a group address
used for RS485 devices. Devices do not answer with this address, useful to change parameters of all
connected devices at the same time.
Command: command have to be completed with a carriage return <CR> (decimal 13).
Parameter (Unless otherwise specified, coded hexadecimal):
without parameter the command reads out the current set value. The answer at request commands
is the set value of the device corresponding to the possible settings described in the table. Answers
are normally finished with a <CR>. Deviating read commands are in parentheses in the respective
write commands.
With parameter the parameter will be set into the device. A setting command answers with
ok+<CR>, this means the command is accepted.
