Description
PIDSelfTune.SUT.AdaptDelay-
Time
INT 0 The AdaptDelayTime tag determines the adaptation of the
delay time for heating at the operating point (for "Pretuning
heating" and "Pretuning heating and cooling").
Options are:
• SUT.AdaptDelayTime = 0:
No adaptation of delay time. The SUT.State = 1000
phase is skipped. This option results in a shorter tuning
time than with SUT.AdaptDelayTime = 1.
• SUT.AdaptDelayTime = 1:
Adaptation of the delay time to the setpoint in
SUT.State = 1000 phase by switching off heating tem-
porarily.
This option results in a longer tuning time than
withSUT.AdaptDelayTime = 0. It can improve the con-
trol response if the process behavior depends signifi-
cantly on the operating point (non-
linearity). This option
should not be used for multi-zone applications with
strong thermal connections.
