PID Configuration (PRoG > PId.S)
Select PId.S to configure the PID control settings. These settings apply to all outputs that have
had their Control Mode set to PID (
7.4.1.2 PID Control Mode (PRoG > oUt1-oUt6 > ModE >
). PID control can be optimized in a variety of ways. The suggested way is to initiate an
Autotune command (
7.5.3 Autotune (PRoG > PId > AUto)
) and then enable adaptive tuning
7.5.7 Adaptive Tuning (PRoG > PId > AdPt)
). The PID parameters may also be set manually or
manually adjusted after an Autotune command has been executed.
Navigate to the desired setting. Settings include the following:
ACtN – Action direction moves up or down to SP1
A.to – Autotuning Timeout sets a maximum amount of time for Autotuning
AUto – Initiates Autotuning
GAIN – Select the proportional, integral, and derivative factors for manual tuning
%Lo – Low clamping limit for Pulse and Analog outputs
%HI – High clamping limit for Pulse and Analog outputs
AdPt – Fuzzy logic adaptive tuning
Select the desired parameter.
7.5.1
Action Response (PRoG > PId > ACtN)
Select the Direction (ACtN) parameter.
Navigate to the desired setting. Settings include the following:
RVRS – “Reverse Action”: Increase to SP1, such as heating (factory default)
dRCt – “Direct Action”: Decrease to SP1, such as cooling
Select the indicated setting.
7.5.2
Autotune Timeout (PRoG > PId > A.to)
Select the Autotune Timeout (A.to) parameter.
Set the amount of time before the Autotune process gives up and times out in Minutes and
Seconds (MM.SS). Slowly responding systems should have a longer time out setting.
Select the indicated setting.
7.5.3
Autotune (PRoG > PId > AUto)
Select the Autotune (AUto) command. The unit displays StRt.
Confirm Autotune activation. The unit attempts to optimize the P, I, and d settings by
stimulating the system and measuring the response. If the A.to time out period expires before
the Autotune operation can complete, the unit displays a failure message E007. If the
Autotune operation completes successfully, the unit displays the message “doNE”.
