ISR 12-LO IGAR 12-LO Operating Manual Introduction 9
2 Introduction
2.1 Appropriate use
The pyrometers ISR 12-LO and IGAR 12-LO are digital, highly accurate 2-color pyrometers with fiber optic for non-contact temperature measurement on metals, ceramics, graphite etc. between 300 and 3300 °C.
The pyrometers measures in the 2-color principle (ratio principle) in which two adjacent wavelengths are used to calculate the temperature. This technique offers the following advantages compared with the standard one-color pyrometers:
The temperature measurement is independent of the emissivity of the object in wide
ranges.
The measuring object can be smaller than the spot size.
Measurements are unaffected by dust and other contaminants in the field of view or by
dirty viewing windows.
Additionally, the pyrometer can be switched to 1-color mode and used like a conventional pyrometer.
The metal mode allows measurements of metals and alloys with unknown K-factor (emissivity slope).
The instrument is equipped with an optical fiber (length up to 30 m), which can be used in very high ambient temperatures up to 250 °C without cooling and it is unaffected by electromagnetic interferences.
2.2 Scope of delivery
Pyrometer, optical fiber and optical head as per configuration, works certificate, PC software InfraWin, and user manual.
Note: The connection cable is not included with the instrument and must be ordered separately (see section 8, Reference numbers).

3 Controls and Connections
3.1 Electrical Installation
The ISR 12-LO and the IGAR 12-LO are powered by a voltage of 24 V DC (15 to 40 V DC) or 24 V AC (12 to 30 V AC). As the instrument is operating with heated and thermostatically controlled sensors, it needs a warm-up of up to 5 minutes (during this warm-up period the LED display indicates “7777“), after that the instrument is ready for use. To switch off the instrument, interrupt the power supply or unplug the electrical connector.
To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used. The shield of the connecting cable must be connected only on the pyrometer’s side. On side of the power supply (switch board) the shield must be open to avoid ground loops.
LumaSense offers connecting cables; they are not part of standard scope of delivery. The main connecting cable has wires for power supply, interface, analog output, external laser switch and external clear of maximum value storage via contact (see section 8, Reference numbers) and 12 pin connector. The cable includes a short RS232 adapter cable with a 9 pin SUB-D connector for direct PC communication. This adapter is not used in combination with RS485 interface.

3.2.1 Connector pin J
The connector pin J can be used for 4 different functions:
1. Operating mode contact: During the warm-up of the pyrometer (after connection to
the power supply, the LED display on the converter indicates “7777”) pin J is connected to the power supply voltage. This voltage is connected by a relays switch (max. continuous current 0.4 A) to pin K (power supply voltage). This relays switch opens when the warm-up is finished, and the pyrometer is in operating mode. For that reason, this pin can be used as operating mode contact.
2. External clearing of the maximum value storage: When the pyrometer is in
operating mode, pin J can be used for external clearing of maximum value storage (see section 4.8). To clear the maximum value storage, connect pin J for a short time to pin K (power supply voltage).
The function “external clearing” is activated with the following conditions:
Warm-up is finished (no display “7777“)
The clear time is set to “extern“ (see section 4.8).
The lens contamination monitoring is switched off. This can be done via software
InfraWin in “color-bar“ window. The warning level “dirty window” must be set to 0% (see section 4.1).
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 4.8 clear time for the maximum value storage).
4. Lens contamination monitoring system: The pyrometers are equipped with a
contamination monitoring system. Contamination of lens or sighting window or dust in the sighting path of the pyrometer can interfere the signal in such a high level that a correct temperature measurement will be impossible (this can also happen if the object is smaller than the spot size of the pyrometer). To avoid wrong measurements in advance, a warning signal can be set to a certain contamination level. If contamination reaches this level (or at a certain too low signal level), a built-in relay (max. continuous current 0.4 A) connects pin J to pin K (power supply voltage). The setting of the switch level (0 … 99%) can be done via software InfraWin in “color-bar“ window. If the warning level “dirty window” is set to 0% (see section 4.1) the lens contamination monitoring system is switched off and pin J has the function “external clearing” of maximum value storage (factory setting).
The lens contamination monitoring system is activated with the following conditions:
Warm-up is finished (no display “7777“)
The clear time is not set to “extern“ (see sections 4.1 and 4.8).
The pyrometer is operating in “2-color mode“ (see section 4.9)
ISR 12-LO IGAR 12-LO Operating Manual Controls and Connections 17
3.3 Connecting the pyrometer to a PC
The pyrometers are equipped with a serial interface RS232 or RS485 (switchable at the pyrometer). Standard on a PC is the RS232 interface. At this interface one pyrometer can be connected if the interface is set to RS232. Only short distances can be transmitted with RS232 and electromagnetic interferences can affect the transmission.
With RS485 the transmission is to a large extend free of problems, long transmission distances can be realized, and several pyrometers can be connected in a bus system. If RS485 is not available at the PC, it can be realized with an external converter which converts the RS485 in RS232 for a standard connection to a PC.
When using a converter RS485 / RS232 take care, that the converter is fast enough to receive the pyrometer’s answer to an instruction of the master. Most of the commonly used converters are too slow for fast measuring equipment. So, it is recommended to use the LumaSense converter (order no. 3 852 430).
With a slow RS485 connection it is also possible to set a wait time at the pyrometer which delay the response of a command to the pyrometer (see 3.4.3 Wait time).
3.3.1 Connecting to RS232 interface
The transmission rate (in baud) of the serial interface is dependent on the length of the cable. Values between 2400 and 115200 Bd may be set.
The baud rate must be reduced by 50% when the transmission distance is doubled (see also
4.14 Baud rate).
Typical cable length for RS232 at
19200 Bd is 7 m.

3.3.2 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 transmission rate of the serial interface in Baud (Bd) is dependent on the length of the cable. Values between 1200 and 115 kBd may be set.
The baud rate is reduced by 50% when the transmission distance is doubled (see
4.14 Baud rate). Typical cable length
for 19200 Bd is 2 km.

The fiber has a blue or red mark for correct connection to the pyrometer. The color mark must be mounted on the pyrometer’s side.
The fiber optic is equipped with a special connector which allows it to fix the fiber only in one position. Please notice that the connector of the fiber with the pin is fixed in the correct position before plug and socket can be bold together.
Note: 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.
Ambient temperature
The fiber and optical head can withstand ambient temperatures up to 250 °C without cooling on the side of the optical head.
Serial number / fiber replacement
The original fiber has a serial number which is also on the pyrometer’s housing. If required, the fiber can be replaced by a new original IMPAC-brand fiber. In this case, the pyrometer has to be calibrated together with the fiber (service).

The FSMA connector on the side of the optical head doesn’t need a special justification if bold together.
3.5 Optical head
Depending on the application, the instrument will be delivered with a small or a big optical head.
Type Ι (small optical head): With the very small dimensions the
optical head I is suited for use in confined spaces. The optics is adjusted
to one of the measuring distances mentioned in the table 3.5.1. The mentioned spot size will be achieved in exactly this distance (other distances on request).
Type ΙΙ (optical head, focusable): With the focusable optical head II each measuring distance can be adjusted within the mentioned limits to achieve the smallest spot size in the required distance. The spot size at the shortest and longest distance is mentioned in the following table 3.5.1 Spot sizes at intermediate distances must be calculated by interpolation.
Type ΙΙ (optical head, fixed adjusted): The fixed adjusted optical head II has a similar size as the focusable optical head but with a fixed focusing distance similar to type I (see table 3.5.1).
Note: The optical heads can be changed against another from the same type. A recalibration of the pyrometer is not necessary.

*) The aperture is the effective lens diameter of the optics. It is depending on the objective length which is changing if the measuring distance will be adjusted. The biggest aperture value belongs to the fully extended objective, the smallest aperture value if the objective is turned to its smallest size. Intermediate values have to be interpolated (e.g. calculating the spot size if the measuring distance varies from the adjusted value).
The spot sizes, mentioned in the table above, will be only achieved at the measuring distances of the corresponding optics or with the focusable optics at the adjusted distance. Decreasing or increasing the measuring distance enlarges the spot size.
Spot sizes for intermediate distances, that are not shown on the optical profiles, may be calculated using the following formula:

Note: The InfraWin program includes a calculator (“IR calculator“) that roughly estimates the unknown values.
Note: The pyrometer can measure objects at any distance, but it has to be at least as big as the spot size of the pyrometer.
3.5.2 Adjusting the required measuring distance with optical head Ι or
ΙΙ, fixed adjusted
A tape can be used to determine the distance between the 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 as well as the size of the spot.
3.5.3 Adjusting the required measuring distance with optical head ΙΙ,
focusable
For adjustment of the correct distance, untighten the fixing nut and vary the length of the optical head by turning the lens tube. In the correctly focused distance the laser has its smallest spot size (sharpest image). After adjustment tighten the
fixing nut.

3.6 Laser targeting light
For easy alignment to the measuring object the pyrometers are equipped with a laser targeting light. The laser marks the center of the measuring spot and corresponds to the spot size. With the IGAR 12-LO the measurement is not effected by the laser targeting light. As the laser targeting light influences the measurement of the ISR 12-LO the last measured value is hold in the analog output. The display shows during this time the intensity of the relative signal. In mono mode the display shows a blinking “8000”. The laser targeting light is switched off automatically after approx. 2 min or after a further push of the PL key.
Note: The smallest diameter of the laser spot indicates the correctly focused measuring distance. The diameter corresponds to the spot size!
The laser targeting light can be switched on and off either by pressing the button at the housing (see also section 3.6 Key panel operation) or by using an external contact (see
3.2 Pin assignment for the connector on the bottom side of the pyrometer) or via PC and the software InfraWin. After two minutes the laser targeting light is switched off automatically.
Warning: To reduce the risk of injury to the eyes, do not look directly
into the targeting laser and do not point the targeting laser into anyone's eyes. The instrument is equipped with a class II laser that emits radiation.
Note: The laser warning signs on the pyrometer should be easily viewable at all times, even after it has been installed.
Note: To prevent the damage of the laser, the pilot light switches off automatically if the internal temperature of the device exceeds approx. 55 °C (it can be switched on again, if the internal temperature is lower than 55 °C)!

4.6 Emissivity ε / emissivity slope K
Emissivity (ε) setting only in mono mode. Emissivity slope setting (K = ε

/ ε2) only in ratio mode.
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 0.1 to 1, equivalent to 10 to 100%). 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 must be adjusted accordingly. Typical emissivity values of various common materials for the two spectral ranges of the instruments are listed below. The tolerance of the emissivity values for each material is mainly dependent on the surface conditions. Rough surfaces have higher emissivities.
In ratio mode (2-color mode) the pyrometer is measuring simultaneously with 2 sensors in adjacent wavelengths. It calculates the temperature by ratioing the radiation intensities of the two wavelengths. This ratio technique eliminates a number of factors that degrade the accuracy of a conventional single-color instrument e.g. measurement independent of emissivity in wide areas, unaffected by dust in the field of view, unaffected by dirty viewing windows or lenses, etc. In some cases, the emissivities of the two wavelengths can differ so that it is necessary to correct the ratio of the two emissivities (ε
1
/ ε2) to get a correct temperature reading. This correction can be done with the emissivity slope setting K. The K-factors of metals are normally higher than 1. For a correct measuring result it is recommended to make a comparison test, e.g. with a thermocouple probe. Then the K-factor must be corrected until the pyrometer shows the same temperature value.
Emissivity values and emissivity slope values of various common materials are listed below:

4.7 Response time / exposure time (t
90
)
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 “0.00” position, the device operates using the time constant 2 ms.
The dynamic exposure time adjustment prolongs the exposure time at the lower range limit.
4.8 Clear time of the maximum value storage (t
CL
)
If the maximum value storage is switched on always the highest last temperature value will be displayed and stored. The storage has to be cleared at regular intervals for exchanging by 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:
At clear time “off“ the max. value storage is switched off and only momentary values are measured.
0.01...25 s:
If any clear time between 0.01 s and 25 s is set, the maximum value is estimated and held in double storage mode. After the entered time the storage will be deleted.
Extern:
The external clearing can be activated and used within an own software (see shapter 7, Data format UPP) or via an external contact (for connection see 3.2, Pin assignment for the connector on the bottom side of the pyrometer). 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 only for a few seconds. Here the maximum value for each object has to be indicated. In the “auto” 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 temperature range. The stored maximum value will be deleted when the temperature of the new hot object exceeds the low limit of the temperature range or adjusted temperature sub range by 1% or at least 2 °C.
Hold:
The function “hold” enables to freeze the current temperature reading at any moment. For this an external push button or switch must be connected (see 3.2.1, Connector pin J) which holds the temperature reading as long as the contacts are closed.

ISR 12-LO IGAR 12-LO Operating Manual Settings / Parameter Descriptions 28
Operation note: Dependent on the settings the maximum value storage either works in single
storage mode or in double storage mode:
Single storage: The single storage is used when you want to reset the stored value using an external impulse via one contact closure from an external relay (i.e. between two measured objects). The relay contact is connected directly to the pyrometer between pins J and K. This mode allows a new value to be established, after each impulse from the reset signal.
Double storage: When entering the reset intervals via push buttons or PC interface the double storage is automatically selected. This mode utilizes two memories in which the highest measured value is held and is deleted alternately in the time interval set (clear time). The other memory retains the maximum value throughout the next time interval. The disadvantages of fluctuations in the display with the clock frequency are thereby eliminated.
Note: The maximum value storage follows the function of adjustment of 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.
4.9 Operating mode
The series 12 pyrometers are designed for use in ratio mode. Additionally, the pyrometers can be used in two other modes:
In the mono mode the pyrometer only, measures in one wavelength and the ratio mode is off. In this case the operating mode is equivalent to a conventional 1-color pyrometer (see 4.6, Emissivity).
The metal mode is a special mode which calculates the temperature combining the ratio and the 1-color signal with an algorithm. The metal mode can be used to determine the temperature of metals and alloys with unknown emissivity ratio (K). It should be used only for a short time to achieve a good approximation of the object temperature if the temperature reading in 2-color or 1-color mode seems to be incorrect. After this the pyrometer must be switched back into 2-color mode and the temperature reading has to be corrected with the adjustment of the emissivity slope K until the instrument shows the temperature determined in the metal mode. A
condition for the use of the metal mode are settings of
ε = 1 and K = 1.
Note: Metal mode can be affected by the setting of the switch-off level, see (4.10).
4.10 Switch-off level (OFF / %)
The switch-off level is a function to avoid measuring errors caused by too low signals. Ratio pyrometers can measure temperatures correctly even with very low signals, i.e. for example through a dirty viewing window or if dust exists in the field of view or if the spot is not filled by the measuring object. If the signal is too low for a correct measurement, the pyrometer interrupts the measurement and displays 1° below of beginning of the temperature range. Depending of the application the switch-off limit can be adjusted between 2 and 50%, ex works at delivery set to 10%.
Note: The smaller the value the higher the chance that daylight or reflections affect a correct measurement.

4.11 Analog Output
The analog output must be selected according to the signal input of the connected instrument (controller, PLC, etc.).
4.12 Setting of subrange (from / to)
You can choose a subrange (minimum 51 °C) within the basic measuring range of the pyrometer. This subrange corresponds to the analog output “from“ describes the beginning of this measuring range, “to“ the end of the range.
Additionally, with the setting of a subrange it is possible to fulfill the requirements of the “auto” clear mode of the maximum value storage (see 4.10).
4.13 Address
For the connecting of several pyrometers with RS485 with one serial interface it is necessary to give each instrument an individual address for communication. First it is necessary to connect each single instrument to give it an address. After that all instruments can be connected and addressed individually. If parameters may 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).
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).
4.14 Baud rate (kBaud)
The transmission rate of the serial interface in Baud (Bd) is dependent on the length of the cable. A standard cable length with RS232 for 19200 Bd is 7 m, with RS485 2 km. The baud rate is reduced by 50% if the transmission distance is doubled.

6 Maintenance
6.1 Safety
Attention during pyrometer services: Should the pyrometer be integrated in a
running machine process the machine has to be switched off and secured against restart before servicing the pyrometer.
6.2 Service
The pyrometer does not have any parts, which require regular service, only the lens has to be kept clean. The lens can be cleaned with a soft cloth in combination with alcohol (do not use acid solutions or dilution). In addition, standard cloths for cleaning glasses or photo objectives can be used.
6.3 Changing of optics
The pyrometers are equipped ex works with a small or a large optical head. The optical heads can be changed against each other. A recalibration of the pyrometer is not necessary. Replacement can be necessary if the lens is scratched or the pyrometer will be used for other measuring distances.

ISR 12-LO IGAR 12-LO Operating Manual Data format UPP (Universal Pyrometer Protocol) 35
7 Data format UPP (Universal Pyrometer
Protocol)
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 Re-turn, 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 ), 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 (ε) of the device with the address 00 is returned
Answer: “0970“ + <CR> means Emissivity = 0.97 or 97.0%

ISR 12-LO IGAR 12-LO Operating Manual Troubleshooting 41
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 to the object.
New correct alignment to achieve the max. temperature signal (see 3.6).
Incorrect focusing of the optics.
Focus correctly to the measuring distance if necessary change lens (see 3.5).
Emissivity slope set too high.
Set lower correct emissivity slope corresponding to the material (see 4.6).
Temperature indication too high
Emissivity slope set too low.
Set lower correct emissivity slope corresponding to the material (see 4.6).
The measurement is influenced by reflections of hot machine parts.
Use mechanical construction to avoid the influence of the interfering radiation
(sighting tube).
Measuring errors
Indicated temperature is immediately 1 °C below beginning of temperature range.
Contamination of the lens or broken fiber.
Clean lens or control the fiber. Recommendation: use of air purge (see 2.6).
Indicated temperature is immediately 1 °C below beginning of temperature range, although
the air purge unit is used. Probably compressed air is not clean or air failed.
Clean the lens and use clean, dry and oil free compressed air.
HF-interferences.
Correct the connection of the cable shield (see 4).
