c WARNING: When operating using RE-CAL or local control, 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.
7.6 Manual Jog Calibration Operation
If the Quick Calibration switch is set to Jog, the calibration will initially close the valve then cause
a small jump in the valve position. The jog calibration process will only allow the user to manually
set the span; zero position is automatically always set at the seat. If an elevated zero is needed a
handheld or other PC-based configuration software is required. When performing a jog calibration,
the LEDs will flash in a sequence of Y-R-R-G (yellow-red-red-green) which indicates that the user
must use the Jog buttons ( and ) to manually position the valve to the 100% position. When the
stem is properly positioned press both the Jog buttons ( and ) simultaneously again to register
the 100% position and proceed. No more user actions are required while the calibration process
is completed. When the lights return to a sequence that starts with a green light the calibration is
complete. An explanation of the various light sequences follows.
7.7 Local Control of Valve Position
Local control of valve position can be achieved from the user interface by holding down both Jog
buttons and the RE-CAL button simultaneously for three seconds. While in this mode the LEDs will
flash a YGRR (yellow-green-red-red) sequence. Use the two Jog buttons ( and ) to manually
control the position of the valve. To exit the local control mode and return to normal operation, briefly
press the RE-CAL button.
7.8 Factory Reset
To perform a factory reset, disconnect power, hold the RE-CAL button down, and reconnect power.
Performing a factory reset will cause all of the internal variables, including calibration, to be reset
to factory defaults. The positioner must be recalibrated after a factory reset. User configured limits,
alarm settings, and valve information will also need to be restored.
c WARNING: 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.
7.9 Logix 3400IQ Status Condition
The blink codes used to convey the status of the Logix 3400IQ digital positioner are described in the
table below. In general, any sequence starting with a green light flashing first is a normal operating
mode and indicates that there are no internal problems. Any sequence starting with a yellow light
flashing indicates that the unit is in a special calibration or test mode, or that there was a calibra-
