A wide range of function quantities are available, which are applied together with
their unit and their decimal places.
Specifies the required gradient as value change/time unit. The value change is
defined by the Differential input variable. If a negative value is entered for the
value change, a falling gradient will be detected.
Positive gradient
The status switches to ON if the rise in
temperature within a tenth of the set
time unit is greater than the set
gradient.
The "Differential" setting in the input
variables should not be less than 2.0 K,
otherwise test value fluctuations could
lead to a false result.
Example:
If the selected gradient is
5.0 K/20 seconds, the controller checks
every 2 seconds whether the
temperature has risen more than 0.5 K.
Negative gradient
The Status switches to ON at the point where the curve of the Temperature change becomes
steeper than the gradient.
