Installation
1. Select a suitable location for the pyrometer. The following criteria must be observed:
• The lens and the field of view of the pyrometer must be free of dirt, smoke and steam.
Otherwise, the air purge PS 01/A must be installed to protect the pyrometer from contami-
nation.
• The permissible operating temperature is 0 - 65 ° C. At a temperature above 65 ° C, the
cooling jacket PK 01/B AF1 must be used. As cooling medium, air or water are possible.
2. Check that the lens is clean. Assemble the pyrometer in the provided bracket and align the
pyrometer to the measuring object. If necessary, check the cooling medium and the maxi-
mum operating temperature.
3. Turn on the power supply of the pyrometer. If the pyrometer features an LED pilot light, this
can be used to align the pyrometer. For 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
screw of the measuring head and move the inner tube in order to obtain a sharp spot on the
measuring area. 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 pyrometer uses the intensity of infrared radiation for non-contact temperature measure-
ments. It is necessary to configure the pyrometer to the respective emissivity coefficient of
the measuring object to obtain exact measuring results (see manual PK, chapter 16). The
emissivity coefficient 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 pyrometer is correct. All parameters can be set directly at
the pyrometer (see manual, chapter 5).
5. It is advisable to take the checking of the pyrometer in the maintenance plan.
The pyrometers of the PK 1x series are only measuring exact results in the state of
thermal stabilization. The break-in period is approximately 10 minutes after starting the
supply voltage.
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 pro-
cess data set-up, diagnostic functions and parameter addresses are available in the download
area at www.keller.de/its/pyrometer.
A 3-wire cable port Class A (Type A) must be used for IO-Link operation.
