preset tuning sets determined by the rotary “Gain”
selector switch. Settings “A” through “H” are pro-
gressively higher gain predefined tuning sets.
The gain selector operates as a “live” switch. This means
that changes to the switch position while the positioner
is in normal operation will have immediate effect on the
control algorithm.
8.3 Setup of the CAL DIPswitches - The last 3
DIP Switches are for calibration configuration.
a. Quick calibration operating mode.
UÊ -iiVÌÊ Auto if the valve/actuator assembly has
an internal stop in the open and closed positions.
In Auto mode the positioner will fully close the
valve and register the 0% position and then open
the valve to the stop to register the 100% position
when performing a self-calibration. See detailed
instructions in section 10.4 on how to perform an
auto positioner calibration.
UÊ -iiVÌÊ Jog if the valve/actuator assembly has no
calibration stop in the open position or if you want
to manually set the closed position. In the Jog mode
the positioner waits for the user to set the open and
closed positions using the Jog buttons labelled with
the
Δ and ∇ arrows. See the detailed instructions in
section 8.4 on how to perform a manual calibration
using the “Jog” buttons.
b. Gain Switch – This switch adjusts the position control
algorithm of the positioner for use with low friction
control valves or high friction automated valves.

for low friction, high performance control valves.
This setting provides for optimum response times
when used with most low friction control valves.

response for valves and actuators with high friction
levels. This setting slightly slows the response and
will normally stop limit cycling that can occur on
high friction valves.
WARNING: During the Quick-Cal operation the valve
may stroke unexpectedly. Notify proper personnel
that the valve will stroke, and make sure the valve
is properly isolated.
c. Loop Calibration- this setting determines whether the
input or output is calibrated when a loop calibration
is initialized.

current source, will be started when the Loop
calibration button is pressed with a small object
with the switch in the Input position. See the
detailed instructions in section 8.7.1 on how
to perform an Input calibration using the Loop
calibration button.
Ê UÊ
˜Ê Output (optional) loop calibration, requiring
an external current meter and power source, will
be started when the Loop calibration button is
pressed with a small object with the switch in the
Output position. See the detailed instructions in
section 8.7.2 on how to perform an Output calibr-
tion using the Loop calibration button.
WARNING: During the Quick-Cal operation the valve
may stroke unexpectedly. Notify proper personnel
that the valve will stroke, and make sure the valve is
properly isolated.
8.4 QUICK-CAL Operation
The QUICK-CAL button is used to locally initiate a
calibration of the positioner. Pressing and holding the
QUICK-CAL button for approximately 3 seconds will initi-
ate the calibration. The settings of all the configuration
switches are read and the operation of the positioner
adjusted accordingly. A QUICK-CAL can be aborted at
any time by briefly pressing the QUICK-CAL button and
the previous settings will be retained.
If the Quick calibration switch (be careful not to confuse
with the QUICK-CAL button) is set to Auto and the valve/
actuator assembly has the necessary internal stops the
calibration will complete automatically. While the cali-
bration is in progress you will notice a series of different
lights flashing indicating the calibration progress. When
the lights return to a sequence that starts with a green
light the calibration is complete. (see the appendix for
an explanation of the various light sequences)
WARNING: When operating using local control of the
valve, the valve will not respond to external
commands. Notify proper personnel that the valve
will not respond to remote command changes, and
make sure the valve is properly isolated.
