2.3.2. Failsafe
The pyrometer has a failsafe function that can be used in analog
mode.
The range can be configured as desired. The settings for fail-safe
operation allow a defined level to be output at the analog output
depending on specified temperature limits.
Thus, a possible cable defect can be detected quickly.

Valid Low
input (digital)
The output follows the process temperature as long as there is a Low level
at the I/O pin. After discontinuation of the Low level the last value will be
held.

The output follows the process temperature as long as there is a High
level at the I/O pin. After discontinuation of the High level the last value will
be held.
