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.
Ê UÊ ATO (air-to-open)- Selecting ATO if increasing
output pressure from the positioner is tubed so
it will cause the valve to open.
Ê UÊ ATC (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.

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.
