The operating function "At.S" in operating mode USER (chap. 7.3) specifies the safety control-
ler set point type "Limit" (Lit) or "Offset" (OFS).
• With set point type "Limit" (Lit), operating function "AL.S" (safety controller set point as limit
value) is displayed in operating modes HAND and USER. You can set a limit value.
• With set point type "Offset" (OFS), operating function "Ot.S" (safety controller set point as
offset value) is displayed in operating modes HAND and USER. You can set an offset
value.
With set point type "Limit", set the safety controller each time the set point for the temperature
is changed. Set the safety controller set point approx. 2 °C above the controller temperature
set point.
Factory setting: set point type "Offset" with safety controller set point 2 °C.
