7.10 Version Number Checking
The version number of the embedded code may be checked at any time
except during a calibration by holding down the up arrow Jog button
( ). This will not alter the operation of the unit other than to change
the blink sequence to three blinks indicating the major version number.

Logix 3400MD Digital Positioner FCD LGENIM3404-00 – 9/09
7.11 375 Handheld Communicator
The Logix 3400MD Quick Start Guide is available from a Flowserve
representative.
The Logix 3400MD digital positioner supports and is supported by the
375 Handheld Communicator. The Device Description (DD) files and the
manuals listed below can be obtained from the FF Foundation or from
your Flowserve representative. For more information please see the
following guides:
• Product Manual for the 375 Communicator.
• Logix 3400MD Digital Positioner Reference Manual.
Diagnostic features such as the signature tests and ramp tests are
performed internally. Certain calibration features such as actuator
pressure sensor calibrations are performed using the 375 Handheld
Communicator or using the Host software.
7.12 Device Description (DD) Files
The DD files for the Logix 3400 can be downloaded from the Flowserve
website, http://www.valvesight.com, or the Foundation Fieldbus
website, www.fieldbus.org.
7.13 Calibration
7.13.1 CALIBRATE_FLAGS
Position 0% Calibration Flag in CALIBRATE_FLAGS
During stroke calibration, the Logix 3400 digital positioner checks to
see if the linkage is placing the stem position sensor in range. If the
valve stroke causes stem position measurement to go out of range in
the closed position, a Position 0% Flag will be generated. The valve
stem will stop in the closed position and the red LED will blink. Linkage
must be adjusted to bring the sensor in range. Special LED indication:
If the linkage is out of range, the LEDs can be used as an adjustment
guide. The LED will change from a red to yellow when the linkage is
brought into range.
Position 100% Calibration Flag in CALIBRATE_FLAGS
During stroke calibration, the Logix 3400MD digital positioner checks
to see if the linkage is placing the stem position sensor in range. If the
valve stroke causes stem position measurement to go out of range in
the open position, a Position 100% Flag will be generated. The valve
stem will stop in the open position and the red LED will blink. Linkage
must be adjusted to bring the sensor in range. Special LED indication:
If the linkage is out of range, the LEDs can be used as an adjustment
guide. The LED will change from a red to yellow when the linkage is
brought into range.
