You can set the
safety controller mode to “Limit” or “Offset”.
• Limit: Limit value, 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 value 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: Offset value, maximum overtemperature above any active temperature set point. The resulting
maximum temperature changes internally and automatically with every temperature set-point change.
Example:
Desired temperature value: 40 °C, desired safety controller value: 45 °C.
Possible settings for this example:
Temperature set point Safety controller mode Safety controller value
40 °C
Limit Limit value 45 °C
Offset Offset value 5 °C
