• The lens and the field of view of the two-colour pyrometer must be free of dirt. Otherwise,
the air purge PS 01/A must be installed to protect the two-colour pyrometer from contami-
nation.
• The permissible operating temperature is 0 - 65 ° C. At a temperature above 65 ° C, a
cooling jacket must be used. As cooling medium, air or water are possible.
2. Check, if the lens of the two-colour pyrometer is dirty. Assemble the two-colour pyrometer in
the provided bracket and align the two-colour pyrometer to the measuring object. If neces-
sary, check the cooling medium and the maximum operating temperature.
3. Turn on the power supply of the two-colour pyrometer. If the two-colour pyrometer features
an LED pilot light, this can be used to align the device. For two-colour pyrometers with fibre
optics, the measuring head must be focussed. For that, the laserpointer is to be connected
to the fibre optic and to be activated by using a button. Follow the safety instructions. For
focal adjustment, loosen the threaded pin of the measuring head and shift the internal tubus
relative to the object. For a correct measuring, focus the measuring head until the spot light
is shown as a sharp round laser spot in the target area.
4. The two-colour pyrometer detects the infrared radiation of the target object on two wave-
lengths. The temperature is then defined by the ratio of these two signals. The emissivity, i.e.
the radiation characteristics of the target may change due to the nature of the surface or in
relation to the temperature, but with simultaneous changes over both wavelengths there is
no influence on the measurement.
Please note: Changing the emissivity ratio can compensate for the difference between
measured temperature and true temperature when selective interfering factors or materi-
al-related different emissivities are affecting Lambda 1 and Lambda 2.
The emissivity ratio is set as follows:
► Press [▲or ▼]
► Press [▲or ▼] until the desired emissivity is shown
► Press [Enter] or wait for 3 seconds
> The current temperature value is displayed and the new emissivity coefficient is stored.
Make sure that the function of the two-colour pyrometer is correct. All parameters can be set
directly at the two-colour pyrometer (see manual, chapter 5).
5. It is advisable to take the checking of the two-colour pyrometer in the maintenance plan.
IO-Link
This device has an IO-Link communication interface, which requires an IO-Link-capable module
(IO-Link master) for operation. The IO-Link interface allows direct access to process and diag-
nostic data and offers the possibility to parameterize the device during operation.
The IODDs required for configuring the IO-Link device as well as detailed information on process data
set-up, diagnostic functions and parameter addresses are available in the download area at
www.keller.de/en/its/mediacenter.
A 3-wire cable port Class A (Type A) must be used for IO-Link operation.
