8.6.6 Module parameters
Wire break in temperature measurement ranges only
Cold junction compensation
Wire break
the Pt1000-sensor for the respective channel in the base module is
defective
 the Pt1000-sensor of the other channel is taken as cold junction.
The diagnostic message ”No Pt1000-sensor found” at both module
channels indicates the usage of a wrong base module.
 A cold junction temperature of 23°C is presumed.
The diagnostic ”Underflow” is generated by the sensor types K, N and
T when the temperature falls below -271.6 °C.
NOTE
Due to a product actualization, the parameter texts of the Turck I/O-products have been
revised.
The actual configuration files (GSD-, GSDML-, EDS-files) with the new parameters can be
found under www.turck.com.
If you use older configuration files with old parameter texts (issue date before April 2014),
then you can find a cross reference list in the manual's appendix (see Cross reference list
parameters (page 523)).
