and commissioning of the ABB 2600T differential pressure
transmitter. This transmitter is connected to a process by
means of impulse lines and can measure Pressure, Differential
pressure or Absolute pressure. The measurement is transmitted
to a control system by means of a 4-20 mA signal with a
superimposed digital signal (HART) or by means of a digital
transmission protocols (PROFIBUS or FOUNDATION
Fieldbus). The measure can also be indicated by means of one
of the (optional) local or remote displays.
Instructions for preliminary checks, proper transmitter location,
installation, wiring, power-up and zero calibration (trimming) of
the transmitter are listed in the following.
In order to assure operator and plant safety it is essential that
the installation is carried out by personnel suitably trained on
the local applicable codes on hazardous location, electrical
wiring and mechanical piping. Please read these instructions
carefully before installing the transmitter. The protection
provided by the equipment may be impaired if the equipment
is used in a manner not specified.
