Automax Logix 3200IQ Digital Positioner
Installation, Operation and Maintenance Instructions
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 three seconds will
initiate the calibration. If the Config-Switches option is
enabled, 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
this 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
calibration 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. An explanation of
the various light sequences follows. The initial calibration
of extremely large or small actuators may require several
calibration attempts. The positioner adapts to the actuator
performance and begins each calibration where the last
attempt ended. On an initial installation it is recommended
that after the first successful calibration that one more
calibration be completed for optimum performance.
WARNING: When operating using QUICK-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.
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
approximately 100%. When the valve is approximately
100% open press both the Jog buttons (
↑
and
↓
)
simultaneously to proceed to the next step. The valve will
stroke and then wait while flashing the Y-R-R-G sequence
again, allowing the user to adjust the valve position a
second time to exactly 100% using the Jog buttons
(
↑
and
↓
). 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.
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
QUICK-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 QUICK-CAL button.
Factory Reset
To perform a factory reset, disconnect power, hold the
QUICK-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. Tag names and other user configured limits,
alarm settings and valve information will also need to
be restored.
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.
Command Source Reset
Performing a command source reset will reset the
command source to analog source if it has been
inadvertently left in digital mode. This is done while a
QUICK-CAL is in process by holding down both the Jog
buttons (
↑
and
↓
) while briefly pressing the QUICK-CAL
button. A new QUICK-CAL must be done after resetting.
Logix 3200IQ Status Condition
The blink codes used to convey the status of the Logix
3200IQ 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
calibration problem. Any sequence starting with a red light
flashing indicates that there is an operational problem
with the unit.
