7.5 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
PId)). PID control can be optimized in a variety of ways. The suggested way is to initiate an
Autotune command
(7.5.7 Adaptive Tuning (PRoG > PId >
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".
