8.3.5 dely (delay) - ramp function
The ramp time for attenuating sudden changes in the input signal can be
entered separately for changes upwards and downwards.
hi [s] - ramp for a positive signal jump
The time indicated in seconds (0.1 to 10.0 s) relates to a change in set-
point from 0 % to 100 %.
lO [s] - ramp for a negative signal jump
The time indicated in seconds (0.1 to 10.0 s) relates to a change in set-
point from 100 % to 0 %.
With smaller changes in the input signal, the delay time corresponds to the
set value multiplied by the size of the change in percent.
For example, with a sudden change from 20 % to 70 %, it corresponds to
exactly half the value set under HI in seconds.
With a setting value of 0.0 s, the respective ramp function is deactivated.
