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

ADDENDUM FOR "METERS" OPTION OF THE TRANSMITTERS

GENERAL DESCRIPTION
This option provides three different indications (meters) inside the transmitter housing. The "output meters" can be mounted on
the terminal block (field terminals) side; one is of "analog" type, the second is of "digital" type (LCD, ProMeter) and the third is
the CoMeter. They are operated by the output signal of the transmitter. The meters can be rotated to exactly match the mounting
position of the transmitter . The above mentioned CoMeter (abbreviation of Communication Meter) can be used both as a display
and as a configuration tool for the Safety 2600T.
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.

METER INSTALLATION OR REPLACEMENT
To install (or to replace) the meter, use the following procedure:
1) If the transmitter is part of a control loop, put the loop in
2) Remove the cover on the terminal block side; inside of

can rotate, for easy viewing, in 15° steps, 90° degree
clockwise and 255° counterclockwise.
Further rotation causes damage to the meter stops or to the
"banana" connections and should be avoided. Note that
considerable effort must be applied for 15° rotation. The
analog output meter can also rotate for easy viewing.

CAUTION - If the meter is removed, ensure that it is
replaced immediately by another one or with the proper
link provided. This operation is important for I.S.
