Configuration Advice

Guided Setup directs you through initialization of configuration data needed for proper operation. When the
instrument comes out of the box, the default dimensions are set for the most common Fisher 249 construction, so if
any data is unknown, it is generally safe to accept the defaults. The mounting sense ­ 'instrument left or right of
displacer' - is important for correct interpretation of positive motion. The torque tube rotation is clockwise with rising
level when the instrument is mounted to the right of the displacer, and counter­clockwise when mounted to the left of
the displacer. Use Manual Setup to locate and modify individual parameters when they need to be changed.

Preliminary Considerations

Write Lock

Field Communicator Overview > Device Information > Alarm Type and Security > Security > Write Lock (1-7-3-2-2)
To setup and calibrate the instrument, write lock must be set to Writes Enabled. Write Lock is reset by a power cycle. If
you have just powered up the instrument Writes will be enabled by default.

Level Offset

Field Communicator Configure > Manual Setup > Variables > Primary Variables > Set Level Offset (2-2-2-1-5)
The Level Offset parameter should be cleared to zero before running Instrument Setup. To clear Level Offset enter the
value 0.0 and press Enter > Send.

Guided Setup

Field Communicator Configure > Guided Setup > Instrument Setup (2-1-1)
Note
Place the loop into manual operation before making any changes in setup or calibration.
Instrument Setup is available to aid initial setup. Follow the prompts on the Field Communicator display to enter
information for the displacer, torque tube, and digital measurement units. Most of the information is available from
the sensor nameplate, shown in figure 4‐1. The moment arm is the effective length of the driver rod and depends
upon the sensor type. For a 249 sensor, refer to table 4‐1 to determine driver rod length. For a special sensor, refer to
figure 4‐2.
