Addendum For "Meters" Option Of The Transmitters - ABB Industrial IT enabled 2600T Series Operating Instruction

ADDENDUM FOR "METERS" OPTION OF THE TRANSMITTERS

GENERAL DESCRIPTION
This option provides four different indications (meters) inside the transmitter housing. Three meters, "output meters", can be
mounted on the terminal block (field terminals) side; the first is of "analog" type, the second is of "digital" type (LCD, ProMeter)
and the third is the CoMeter. All are operated by the output signal of the transmitter. The fourth meter, "integral digital display",
is mounted on the electronics side: it is of "digital" type (LCD, 4-digit), microprocessor driven. The integral digital display has 4
different mounting positions. The analog meters can be rotated to exactly match the mounting position of the transmitter.
ANALOG OUTPUT METER
The analog output meter provides a 90° scale indication. It has
either a 0 to 100 linear scale or a 0 to 10 square root scale.
ANALOG OUTPUT METER CALIBRATION
The calibration of the analog type meter only involves zeroing.
Fig. 1 shows the analog output meter and the location of the
zero adjustment.
The calibration is quite simple using one of the following
methods:
- with the loop unpowered adjust the zero screw to read exactly
the true zero mark on the scale (Fig. 1).
- with the transmitter transmitting 4 mA adjust the zero screw
to read exactly the live zero of the scale.

INTEGRAL DIGITAL DISPLAY MICROPROCESSOR
DRIVEN
On the Secondary electronics can be fitted an integral digital
display.
It can be used, together with local keys, for transmitter
configuration, as well as for display various type of information,
from Process Variable to output percentage.
In addition, also diagnostic information are provided, in the way
that only the highest priority message will appear and when it
disappear, other message, next in priority order, will be given.
Zero adj.
Here follows a list of error and warning message, in priority
order:
"ELECTRONIC FAIL"
"SENSOR INVALID"
"SENSOR FAIL"
"PV SENS OUTLIM"
"STATIC PRESS"
"SENS TEMP"
"OUT SATUR"
"OUT FIXED"
"DAC OUTRANG"
These indication are self explanatory as far as the possible
repair action is concerned.
The integral digital display is an option for the 2600T series
transmitter. When it is fitted on the transmitter, the latter
automatically detects the presence and allows the use of local
keys for operations with the display.
The first message that is given, when the display is fitted or at
power on is: ABB - HART. Then the indication selected and the
bargraph appear, as in the next example.
