Configuration, parameterization

NOTICE – Potential damage to device as a
result of electrostatic charging!
When the housing is open, EMC protection is
impaired and there is no longer any protection
against accidental contact.
Do not touch conductive parts of the device.
7.1.1

Standard configuration

Transmitters are set to the customer's specified span at the
factory. The set range and measuring point number are
provided on the name plate. If this data has not been
specified, the transmitter will be delivered with the following

configuration:

Parameter
4 mA
20 mA
Output
Damping
Transmitter failure mode
Opitional LCD display
Any or all of the configurable parameters listed above,
including initial value and final value, can easily be changed
using the optional LCD indicator, a portable HART handheld
terminal communicator, or the SMART VISION or ASSET
VISION BASIC configuration software with DTM for 2600T
which can be run on a PC.

Configuration types

Pressure transmitters can be configured as follows:

— Configuration using pushbutton on pressure transmitter.

— Configuration with the LCD indicator.
— Configuration with the PC / laptop or handheld terminal.
— Configuration via graphical user interface (DTM).

General remarks

The pushbutton is located on the electronics unit (without
mounted LCD indicator).
The pushbutton is used to set the "Lower Range Value" (0 %)
and "Upper Range Value" (100 %) parameters.
To access the pushbutton, you must remove the housing
cover for the electronics unit.
The pushbutton (1) is located in the bore hole and can be
pressed with a pin or screwdriver with a diameter of
≤ 2.5 mm.

7.3.2 Configuration
The "Lower Range Value" and "Upper Range Value"
parameters can be set directly on the transmitter using a
button. The transmitter has been set by the manufacturer
based on the order information.
The name plate contains information on the "Lower Range
Value" and "Upper Range Value" that have been set.
In general, the following applies:
For a setting, e.g., of 0 ... 40 kPa, the first pressure value
(0 kPa) is always assigned to the 4 mA signal and the second
pressure value (40 kPa) is always assigned to the 20 mA
signal.
To reset the transmitter, apply the pressure for the "Lower
Range Value" and "Upper Range Value" to the measuring
equipment. Make sure that the measuring limits are not
exceeded.
Reducing stations can be used as transducers with adjustable
pressure and reference displays.
IMPORTANT (NOTICE)
When making the connection, please ensure that
there are no residual fluids (for gaseous
measured media) or air bubbles (for fluid
measured media) in the connection lines, since
these can lead to errors during inspection.
