ABB 266MST User Manual

2600T Series Pressure transmitters | OI/266/HART-EN Rev. M 59
8 Operation
8.15.7 Cylindric lying tank
This function is used to measure the volumetric level into a
cylindrical horizontal tank with flat ends.
The transmitter calculates the volume from the measured filling
level.
8.15.8 Spherical Tank
This function is used to measure the volumetric level into a
spherical tank.
The transmitter calculates the volume from the measured filling
level.
8.16 Configuration with the PC/laptop
or handheld terminal
A graphical user interface (DTM) is required for configuration of
the transmitter via PC or laptop. For operating instructions,
please refer to the software description.
A - Transmitter
B - Supply unit (communication resistor
not provided in supply unit)

The 266 transmitters can be configured by either one of the
following device.
— Hand Held terminals like the ABB 691HT, ABB DHH800-
MFC, Emerson Process 375 and 475 provided the 266
EDD has been downloaded and enabled in the terminal.
— ABB Asset Vision Basic, a new free of charge software
configurator downloadable at www.abb.com/
Instrumentation.
— Any DTM based software for HART instruments
configuration provided it is compatible with EDD or DTM.
You can use a handheld terminal to read out or configure/
calibrate the transmitter. If a communication resistor is installed in
the connected supply unit, you can clamp the handheld terminal
directly along the 4 ... 20 mA line. If no communication resistor is
present (min. 250 Ω), you will need to install one in the line. The
handheld terminal is connected between the resistor and
transmitter, not between the resistor and supply unit.
