12.2.1 Safety controller modes
You can select between “Limit (absolute)” and “Offset (relative)” safety controller mode
•
Limit:
Absolute maximum permitted temperature value
This setting offers high safety as a defined temperature limit will not be exceeded. It is important to
adapt the safety controller set-point after each modification of the temperature set-point. Otherwise,
the limit could be too high to ensure efficient protection, or, in the opposite case, it could prevent the
controller from reaching an entered set-point outside the limit range.
•
Offset:
Maximum overtemperature above any active temperature set point. The maximum tempera-
ture changes internally and automatically with every set-point change.
This setting is recommended for program operation. It is important to check the safety controller set-
point and safety controller mode occasionally, as it does not offer a fix, independent limit temperature
value, which would never be exceeded.
Example:
Desired temperature value: 21 °C, desired safety controller value: 25 °C.
Possible settings for this example:
Temperature set point
Safety controller mode
Safety controller set-point
21 °C
Limit (absolute)
25 °C
Offset (relative)
4 °C
