To perform a factory reset, hold ► ACCEPT/QUICK-CAL
button while applying power. All of the internal variables
including calibration will be reset to factory defaults. The
positioner must be re-calibrated after a factory reset. Tag
names and other user configured limits, alarm settings, and
valve information will also be lost and need to be restored.
A factory reset will always reset the command source to
analog 4-20 mA.
NOTE:
Once the Multi-Function Card (MFC) type has
been configured, the type selection will still remain after a
factory reset.
CAUTION:
Performing a factory reset may result in the
inability to operate the valve until reconfigured properly.
Notify proper personnel that the valve may stroke, and
make sure the valve is properly isolated.
22.5 Viewing Version Numbers
The version number of the embedded code may be
checked at any time except during a calibration. To see
the major version number, hold the ▲Up button. This will
not alter the operation of the unit other than to change the
blink sequence to 3 blinks indicating the major version
number. Holding the ▼Down button will give the minor
version number without affecting operation. The version
codes are interpreted according to the following table:

For example, if holding the
▲Up button gave a G-G-R
code, and holding the
▼Down gave a Y-Y-G code then the
resulting version number would be 2.12.
22.6 Analog Input Calibration
The Analog Input Calibration allows the user to define the
mA current that will designate the 0% and 100%
commands. This is done by holding down both the
◄
BACK and the
►ACCEPT/QUICK-CAL button for about 3
seconds. The blink code should change to GRYG. Adjust
the input current to correspond with the 0% position
(usually 4 mA). Briefly press
the ►ACCEPT/QUICK-CAL
button. The blink code should change to GRYY. Adjust the
input current to correspond with the 100% position (usually
20 mA). Briefly press t
he ►ACCEPT/QUICK-CAL button.
22.7 Select and Calibrate Analog Output
To change the Multi-Function Card to the Analog Output
function and calibrate, hold down both the
◄ BACK and the
▲Up button for about 3 seconds. The blink code should
change to GYRG. If desired, adjust the output current for
the 0% position by pressing the ▲Up or ▼Down button.
Briefly press
the ►ACCEPT/QUICK-CAL button. The blink
code should change to GYRY. If desired, adjust the output
current for the 100% position by pressing the ▲Up or
▼Down button. Briefly press the ►ACCEPT/QUICK-CAL
button.
22.8 Select Discrete Output
The Discrete Output mode generates a high current of
about 7 mA in the normal state. When the Position
Deviation alarm is tripped, the output changes to 0.5 mA.
To change the Multi-Function Card to the Discrete Output
function, hold down both the
◄ BACK and the ▼Down
button for about 3 seconds. The blink code should change
to GRYR. Briefly press
the ►ACCEPT/QUICK-CAL button.
