2 Introduction 2.1 Appropriate use The pyrometers IS 50-LO plus and IGA 50-LO plus are digital, highly accurate pyrometers with fiber optics for non-contact temperature measurement on metals, ceramics, graphite etc. between 250 °C and 3500 °C. The IS 50/055-LO plus and IS 50/067-LO plus are special versions with extremely short wavelengths where e.g. molten metal has a very high emissivity. The instrument type IS 50-Si-LO plus is optimized for measurements on silicon wafers, e. g. in vacuum chambers.

The following overview shows a selection of suitable accessories. You can find the entire accessory list with all reference numbers in Section 10.
3 Controls and Installation 3.1 Electrical Installation The series 50 pyrometers are powered by a voltage of 24 V DC (possible range 12 ... 30 V) or AC (48 ... 62 Hz). Once connected to power, the instrument operates immediately and needs no warm-up time. To switch off the instrument, unplug the connector. To meet the electromagnetic requirements, a shielded connecting cable must be used. The shield of the connecting cable has to be connected only on the pyrometer side to avoid ground loops.
3) hold function: when the hold function mode is activated the current temperature reading is frozen as long as J and pin K are connected (see 5.3 Clear time for the maximum value storage). 3.1.2 Connecting the pyrometer to a PC The pyrometers are equipped with a serial interface RS232 or RS485 (switchable at the pyrometer). Only one pyrometer can be connected on the standard PC RS232 interface.
3.1.3 Connection of additional analyzing devices Additional analyzing instruments (such as LED digital display instruments) only need to be connected to a power supply and the analog outputs from the pyrometer. Another Instrument, such as a controller or printer, can be connected to the display in series as shown below (total load of resistance max. 500 Ohm). white 230 V ~ 24 V DC Power supply brown green °C LED digital display Controller Writer Converter 3.2 Mechanical Installation 3.2.
The fiber has a color mark for correct connection to the pyrometer. This color mark has to be mounted on the pyrometer’s side. On side of the optical head no mark or a black mark is viewable. Attention: The light guide end of the fiber optic cable as well as the socket/connector and the optical head must always be protected with the caps when not connected! Minimum Bending Radius Red Blue Green for short time (max. 250 °C): 50 mm 100 mm 150 mm permanent (max.
Caution: Do not look directly into the laser beam! Laser class 2 according to IEC 60825-1-3-4 Note: To prevent damage to the laser, the laser targeting light switches off automatically if the internal temperature of the device goes above approx. 55 °C (then it cannot be switched on again until the temperature is lower again)! Note: The laser warning signs on the pyrometer should be easily viewable at all times, even after it has been installed. 3.
Note: The measuring object has to be bigger than or at least as big as the spot size of the pyrometer. 3.4.2 Adjusting the required measuring distance A tape can be used to determine the distance between object and pyrometer. The measuring distance is always measured from the front of the lens. If the laser is switched on, its smallest spot is in the measuring distance of the corresponding optics or adjusted distance and it marks the center and size of the spot.
4 Instrument settings The pyrometers are equipped with a wide range of setting options for optimal adaption to the required measuring condition and for getting the correct measuring temperature (description of all available parameters see Chapter 5 Parameter description / settings). All instrument settings can be done directly at the instrument or via serial interface and software InfraWin.
2 3 If the converter cover is opened the laser targeting light can be switched with the button with the symbol. When the laser targeting light is switched on, the display shows “PILT”. : With the arrow keys and all parameter settings can be displayed. They are active after pushing the PAR button. Pushing the button longer changes the settings in fast mode. ESC / ENT: Pushing the ESC button changes the pyrometer to measuring mode.
5 Parameter descriptions / Settings 5.1 Emissivity For a correct measurement, it is necessary to adjust the emissivity. The emissivity is the relationship between the emission of a real object and the emission of a blackbody radiation source (this is an object which absorbs all incoming rays and has an emissivity of 100%) at the same temperature.
5.2 Exposure time (t90) The exposure time is the time interval when the measured temperature has to be present after an abrupt change so that the output value of the pyrometer reaches a given measurement value. The time taken is to reach 90% of the recorded temperature difference. In the “min” position, the device operates using its time constant of < 1 ms. Longer exposure times can be used for the measurement of objects which have rapidly fluctuating temperatures to achieve constant temperature reading.
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. Hold: The function “hold” enables to freeze the current temperature reading at any moment. For this an external push button or switch has to be connected (see 3.1.
5.9 Wait time (tw) 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 a wait time of 2/9600 sec). Settings: 00 .Bit .. 99 Bit Note: Only available via interface commands, see Chapter 9, Data format UPP. 5.
6 Software InfraWin The operating and analyzing InfraWin software is included with delivery of the pyrometer. In addition to allowing you to make parameter adjustments via PC, the InfraWin software also provides temperature indication, data logging, and measurement analysis features. A software description can be found in the program’s help menu. Click on the F1 button after loading InfraWin or click on the ? in the menu bar. The latest version is available for free as download from the homepage www.

7 Maintenance 7.1 Cleaning the front window Since the device does not contain parts that require regular maintenance, the only regular maintenance required is periodic inspection of the front window for build-up of foreign particiles. If allowed to build up, the particles can influence the energy received by the instrument. The window is not water soluable and can be cleaned with standard lens tissue dampened with a commercially available glasses or camera lens cleaning solution.

8 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 to the object New correct alignment to achieve the max. temperature signal Measuring object is smaller than spot size. If needed, exchange optical head. Choose correct measuring distance Measuring object is not always in the measuring spot of the pyrometer (e.g.

9 Data format UPP (Universal Pyrometer Protocols) Via interface and a suitable communication software or via “Test” function of the InfraWin software 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.
