11. General instructions for performing temperature tests
The purpose of these instructions is to explain general procedures for performing application-
specific temperature tests with B&R industrial PCs or Power Panels. However, these instructions
are meant to serve only as a guideline.
11.1 Procedure
In order to obtain accurate results, the testing conditions should match the conditions in the field.
This means that for the duration of the temperature tests, the target application should be
running, the PC should be installed in the control cabinet that will be used, etc.
Additionally, a temperature sensor should be installed for the device being tested to provide live
monitoring of the ambient temperature. In order to obtain accurate measurements, this sensor
should be mounted at a distance of 5 to 10 cm from the B&R industrial PC, near the air intake
(not near the exhaust).
All B&R industrial PCs and Power Panels are equipped with internal temperature sensors. These
are installed in different locations for each series. The number of sensors and the temperature
limits also vary from series to series.
Information about the locations of temperature sensors and the maximum specified values can
be found in section "Temperature sensor locations", on page 471.
To ensure a reliable evaluation of the temperature situation, a minimum of 8 hours are
recommended for testing.
