The inputs INP and IN2 are additionally monitored
in regards to the limit value AL=150°C
Example
Example
diF = INP-IN2 are shown in the picture.
Inside the valid all values
the difference ALd = 50.
INP = 101°C,
101 - 50 = 51 exceeds Ald = 50 and lies out of the

Example 1:
IN2 = 50°C
INP = 50°C, IN2 = 50°C
50 - 50 = 0
.
INP = -50°C, IN2 = 50°C
-50 - 50 = 100
