3 Controls and Installation

3.1 Electrical Installation

The instruments are supplied by 24 V DC (± 25%) and a ripple < 50 mV. Ensure correct polarity
when connecting the instrument to the power supply. The power consumption (in this case,
4 ... 20 mA) is also the measuring signal. The instrument doesn’t need any time for starting or
preheating and is immediately ready for operation. To switch off the instrument, interrupt the
instrument’s power supply.

Cable colors: White: +24 V DC Green: LED +5 ... 30 V DC
Brown: 0 V Yellow: LED 0 V
Black: Screen

To meet the electromagnetic requirements, a shielded connecting cable must be used. The
shield of the connecting cable is usually only connected on the pyrometer side. If the connecting
cable is extended, the extension cable also needs to be shielded. Do not connect the shield in
the control cabinet to avoid ground loops.

3.2 LED targeting light

The pyrometers are equipped with an LED targeting light for aiming onto the measuring object.
The center of the light marks the center of the spot. For use of this targeting light, a separate
power supply is necessary with 5 ... 30 V DC and a current of I ≤ 30 mA.

Measuring is possible while the LED targeting light is on. We recommend using a low supply
voltage to keep the thermal loading of the pyrometer small.

3.3 Optics

The pyrometers are equipped ex works with one of the following optics. These optics focus to a
certain distance, i.e. in these distances each optics achieves its smallest spot size in relation to
the measuring distance. The spot size will change in any other distance (shorter or longer).
Please note that the measuring object must be as least as big as the spot size.

IS 310 / IGA 310 Manual Controls and Installation • 13

The following drawing and table shows the size of the spots in mm in relation to 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.

4 Parameter Descriptions / Settings

4.1 Emissivity (ε)

For a correct measurement, it is necessary to adjust the emissivity ε. 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 0.2 ... 1, equivalent to 20 … 100%). Additionally, the
emissivity is dependent on the surface condition of the material, the spectral range of the
pyrometer, and the measuring temperature. The emissivity setting of the pyrometer has to be
adjusted accordingly. Typical emissivity values of various common materials for the two spectral
ranges of the instruments are listed in the emissivity table below. The tolerance of the emissivity
values for each material is mainly dependent on the surface conditions. Rougher surfaces have
higher emissivities.

Note: The pyrometer is set ex works to an emissivity of 100%.

To adjust the emissivity factor to your own
purpose, you have to remove the rear cover
by unscrew the locking screw. Be sure to
remove the cover carefully. In the tube there
is a scale that can be turned with a small
screwdriver. Adjust the emissivity factor to
your desire. After that, push the cable
carefully back in the tube, put the cover on
the tube and tighten the locking screw for
the cover.

The following table may give brief information of the correct setting of the emissivity. For exact
measurement we recommend a comparison measurement with a contact thermometer (e.g.
TASTOTHERM MP 2000 with a suited probe).

5 Maintenance

5.1 Safety

If the pyrometer is integrated into a running machine process, the machine has to be switched
off and secured against restart before servicing the pyrometer.

5.2 Service

The pyrometer has no serviceable internal parts. The lens can be cleaned with compressed air,
which is dry and free of oil. If the lens requires a more thorough cleaning, use a soft, dry cloth
(such as a clean camera lens cloth).

Caution: Do not clean or touch the lens with acids or solvents!

IS 310 / IGA 310 Manual Troubleshooting • 19

6 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

⇒ Check measuring distance, smallest spot size is at nominal measuring distance (see 3.3)

• Emissivity set too high

⇒ Set lower correct emissivity corresponding to the material (see 4.1)

• Lens contaminated

⇒ Clean lens carefully (see 5.2)

Temperature indication too high

• Emissivity set too low

⇒ Set higher correct emissivity corresponding to the material (see 4.1)

• The measurement is influenced by reflections of hotter machine parts

⇒ Try to avoid the influence of the interfering radiation or change measuring position

Measuring errors

• Indicated temperature is decreasing during the use of the pyrometer, contamination of

the lens

⇒ Clean lens Recommendation: use of air purge

• Indicated temperature is decreasing during the use of the pyrometer, 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

• Strong HF-interferences

⇒ Correct the connection of the cable shield (see 3.1)

• Instrument overheated

⇒ Use cooling jacket with air or water cooling
