NOTE: The switch settings in the Conﬁguration box

are activated only by pressing the Quick-Cal button.

Operation of CONFIGURATION DIPswitch Setup -The

ﬁrst 5 DIP Switches are for basic conﬁguration.

a. Air Action - This must be set to match the conﬁguration

of the valve/actuator mechanical tubing connection and

spring location since these determine the air action of

the system.

ÊUÊATO (air-to-open)- Selecting ATO if increasing

output pressure from the positioner is tubed so

it will cause the valve to open.

ÊUÊATC (air-to-close)- Selecting ATC if increasing

output pressure from the positioner is tubed so

it will cause the valve to close.

b. Signal at Closed - Normally this will be set to 4 mA for

an Air-to-open actuator, and 20 mA for an Air-to-close

actuator conﬁguration.

when the signal is 4mA and fully open when the

signal is 20 mA.

this feature.

e. Auto Tune -This switch controls whether the positioner

will auto tune itself every time the quick cal button is

pressed

UÊ On enables an automatic tuning feature that will auto-

matically determine the positioner gain settings every

time a “Quick-Cal” is performed. The gain settings can

be modiﬁed after a calibration by adjusting the rotary

“Gain” switch.

NOTE: there is a small black arrow indicating the selec-

tion. The slot does not indicate the chosen gain.
