3Controls and Installation
3.1 Electrical Installation
The series 5 pyrometers are powered by 24 V DC nominal (possible range: 18 to 30 V DC, ripple
must be less than 0.5 V). When connecting the device to the power supply ensure correct
polarity. The instrument has no warm-up time, with connection to the power the instrument
operates immediately, but still needs 15 or 30 min (depending on the type, see technical data) to
achieve its full accuracy. 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 has to 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
connecting cable has wires for power supply, interface, analog output, external laser switch and
external clear of maximum value storage via contact (see section 10, Referenc e 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.

IN 5/5 plus Operating Manual Controls and Installation •14
3.1.2 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
I-7520 (order no. 3 852 430).
3.1.3 Connecting to RS232 interface
The transmission rate (in baud) of the
serial interface is dependent on the length
of the cable. Values between 1200 and
19200 Bd may be set.
The baud rate has to be reduced by 50%
when the transmission distance is doubled
(see also 5.7 Baud rate)
Typical cable length for RS232 at
19200 Bd is 7 m.
3.1.4 Connecting to RS485 interface
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 19200 Bd may be set.
The baud rate is reduced by 50% when the
transmission distance is doubled (see
5.7 Baud rate). Typical cable length for 19200 Bd is 2 km.

IN 5/5 plus Operating Manual Controls and Installation •15
3.1.5 Connection of additional analyzing devices
Additional analyzing instruments, for example a LED digital display instrument only needs to be
connected to a power supply and the analog outputs from the pyrometer. Another Instruments
like a controller or printer can be connected to the display in series as shown above (total load
of resistance max. 500 Ohm).
3.2 Sighting
For exact measurement of the object temperature the pyrometer must be aligned correctly onto
the object. For this alignment the pyrometers are equipped with a laser targeting light. This
laser enables the simple and accurate alignment even onto small objects.
3.2.1 Alignment with laser targeting light
The laser point marks the center of the spot, not the exact size. The
correct focusing distance with the smallest spot size is achieved
when the laser point has its smallest size. The laser does not affect
the temperature measurement.
The laser targeting light can be activated either by pressing the
button at the rear side of the housing, by using an external contact
(see 3.1.1 Pin assignment for the connector on the back of the
pyrometer), or with the InfraWin software. The laser can be
switched off by pressing the button again or it is automatically
switched off after approx. two minutes.
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. 50 °C (it can switched-on
again, if the internal temperature is lower than 50 °C).

IN 5/5 plus Operating Manual Controls and Installation •16
3.2.2 Thermal alignment
When measuring a hot object in front of a cooler background, it usually suffices to align the
pyrometer to achieve the highest temperature reading.
3.3 Optics
The pyrometers are equipped ex works with one of the following optics. These lenses are
focusing to certain distances. In these distances each lens achieves its smallest spot size. The spot
size will enlarge in any other distance (shorter or longer). Please notice that the measuring
object must be as least as big as the spot size.
The name of the optics (e.g. optics 300) shows the measuring distance in mm (e.g. 300 mm) in
which it has the smallest spot size (IN 5 plus, e.g. 6 mm).
The following drawings show the size of the spots 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:

4.1 Instrument settings
Before using the pyrometer, some basic settings should be taken. The basic settings can be done
at the pyrometer itself, some further settings can be done via interface and software InfraWin.
Settings at the instrument: The basic settings are emissivity, exposure time, analog output.
These settings can be adjusted at the pyrometer only in offline mode (see 5.1 Online- / offline
mode (ONL/OFFL)).
Settings via serial interface: The pyrometer is equipped with a serial interface RS232 or
RS485 (corresponding to the ordered version) 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 (the pyrometer must be in online mode (ONL) to use these functions,
see 5.1): emissivity, 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.
4.1.1 Switches at the instrument
The controls / switches are located under
the rear cover of the pyrometer and can
be accessed by removing the rear cover in
the following way:
1. Disconnect the electrical
connection.
2. Unscrew the rear screws with a
2.5 mm allen screw.
3. Take the cover off, making sure it
remains straight (without bending
or twisting it).
Note: Please make sure that the pyrometer is not contaminated while open.
Assembling: When reassembling the cover, insert it carefully into the guide pins and then fasten
it with the screws. The connector cable can now be plugged in.
