3 Controls and Connections 3.1 Electrical Installation The IGA 320/23-LO is powered by a voltage of 24 V DC (possible range 10 to 30 V, 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.
3.2 Connecting the pyrometer to a PC The pyrometer is equipped with an 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 an RS485 connection is not available at the PC, it can be accomplished using the RS485 to USB connector.
3.2.3 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). white 230V ~ Power supply 24 V DC brown green °C LED digital display Controller Writer yellow 3.3 3.3.

distance. The spot size at the shortest and longest distance is mentioned in the table in section 3.5.1. Spot sizes at intermediate distances have to be calculated by interpolation. Type (large optical head, fixed adjusted): The fixed adjusted optical head has a similar size as the focusable optical head but with a fixed focusing distance (see table 3.5.1) as type (other distances can be realized on request). Note: The optical heads can be changed against another from the same type.
If the LED is switched on, its smallest spot is in the measuring distance of the corresponding optics or adjusted distance and it marks the center of the spot. 3.5.3 Adjusting the required measuring distance with optical head focusable To adjust the correct measuring distance, untighten the fixing nut and vary the length of the optical head by turning the lens tube. When correctly focused, the LED has its smallest spot size (sharpest image). After adjustment, tighten the fixing nut.
4 Settings / parameter descriptions The pyrometer is equipped with a wide range of settings for optimal adaptation to the required measuring condition and to measure the temperature correctly. All settings can be read and set only in the pyrometer parameters window of the software InfraWin. Adjusting the settings at the instrument is not possible (detailed description of the software see Chapter 5, Software InfraWin). Selecting the pyrometer parameters window shows the current settings of the pyrometer.
4.5 Emissivity 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 blackbody 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 100%).
4.9 Clear time of the maximum / minimum value storage (tCL) If the maximum value storage is always switched on, the highest last temperature value will 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.
4.10 Analog output The analog output has to be selected according to the signal input of the connected instrument (controller, PLC, etc.). 4.11 LED targeting light Settings: 0 ... 20 mA 4 ... 20 mA If the pyrometer is supplied with power, the LED targeting light is automatically active. Once connected, it can be adjusted even if the targeting light is off. Independent of this setting, the targeting light can be switched on or off (targeting icon ) using the software InfraWin. 4.
4.15 Limit switch (SP1) The pyrometer is equipped with a switch contact (opto relays; max. 50 V DC, 0.2 A; max. power 300 mW), controlled from the measuring signal. The contact is activated with: Close above: The contact closes (switches to ground), if the temperature entered in the SP1 box is exceeded. If the temperature falls below that value minus the hysteresis the contact opens (a hysteresis between 2 and 20 °C can be set to avoid oscillating of the switch in the switch point).

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.
5.4 Basic settings All preset values for the device can be displayed and modified, if necessary, through the pyrometer parameters of the Devices/Parameters window. 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. This window contains the parameter settings described in Chapter 4, Parameters. 5.4.1 Open/Save 5.4.2 1 measur… 5.4.
In the lower part of the window the connection with the preset baud rate can be checked. Here the command was sent 500 times with 19200 baud. It has taken 4.011 seconds without transmission errors. 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: 219.0°C).
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.
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 non-focused regions.
