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. The
Gain Selector switch is
also read and action will be taken to adjust the gain according
to the settings of the calibration switches as described in the
previous section. 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 (not to be confused with the
Quick-Cal button) is set to Auto and the valve/actuator as-
sembly 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. (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.
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 auto-
matically always set at the seat. If an elevated zero is needed
a handheld or other PC based configuration software is re-
quired. The LEDs will then flash in a sequence of Y-R-R-G
(yellow-red-red-green) which indicates the user must now use
the
Jog keys to manually position the valve to the desired
100% position. Now press both Jog buttons simultaneously
to proceed to the next step. The valve will then stroke and
then wait while flashing the Y-R-R-G sequence again, allow-
ing the user to adjust the valve position a second time to ex-
actly 100% using the
Jog buttons. When the stem is properly
positioned press both Jog buttons simultaneously again to
register the 100% position and proceed. No more user ac-
tions 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. (See the appendix for an ex-
planation of the various light sequences.)
Local control of valve position — Can be done from the user
interface by holding both jog buttons and then simultaneously
pressing the
Quick-Cal button. While in this mode the LEDs
will flash a Y-G-R-R (yellow-green-red-red) sequence. To exit
the local control mode and return to normal operation, briefly
press the
Quick-Cal button.
Factory reset — hold Quick-Cal button while applying power
and 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 need to
be restored. A factory reset will always reset the command
source to analog 4-20 mA.
Special settings––several adjustments to the Logix 520 such
as split-range, MPC, soft stop, etc. cannot be set using the
local interface.
To set these parameters please refer to the appropriate com-
munications tool manual.
9.4 HART 275 HANDHELD COMMUNICATOR
The Logix 520 si supports and is supported by the HART 275
Handheld Communicator. The DD and the manuals listed be-
low can be obtained from the HART Communication Founda-
tion or from your Flowserve representative. For more infor-
mation please see the following guides:
