Foundation Fieldbus - ABB 2600T Série Mode D'emploi

4.6.2 Standard HART
Standard HART protocol is available on 266DSH, 266PSH, 266VSH,
266HSH (with the exeption of ranges V and Z), 266NSH (and the
relevant direct-mounted or remote diaphragm seal versions) as well as
on 266DHH and 266DLH. Standard HART protocol connection board
features 4 dip switches.
Switch 1 and 2 are for Fail Low/Fail High selection.
Switch 3 identifies the external push buttons functionalities: Zero/Span
adjustments or PV Bias-Offset / PV Bias Reset.
Switch 4 allows user to enable the write protection.
Dip switch functions are the same as here above.
In addition, 266 standard HART connection board can the Zero and
Sapn pushbuttons (in case not configured during the codification
process). This buttons work exactly like the external ones located
under the instrument stainless steel nameplate and they can perform
Zero and Span adjustments as well as PV Bias and Offset (if the
proper dip switch is positioned correctly).
4.6.3 PROFIBUS PA
There are 3 dip switches located on this kind of secondary electronics
(as indicated by the figure); they are used for settings when integral
display is not available.
Switch 1 and 2 allow the REPLACE MODE for sensor or secondary
electronics.
Switch 3 identifies the external push buttons functionalities: Zero/Span
adjustments or PV Bias-Offset / PV Bias Reset.
The electronic label clearly explains how to perform all the possible
selection, but please remember that all the operations with the dip
switches should be carried out when the transmitter is powered off so
as to upload new configurations at instrument start-up.
Replace mode (switch 1 and 2)
Usually switches 1 and 2 are down in "0" position.
They are moved when a replace operation is required.
Switch 1 up in "1" position is required before power up the transmitter,
when user needs to replace the electronics or the sensor.
Switch 2 down in "0" position allows the replace of the secondary
electronics. It must be moved in this position before power up the
transmitter.
Switch 2 up in "1" position indicates that a new sensor has been
installed.
AFTER ANY REPLACE OPERATION IT IS RECOMMENDED TO MOVE
DOWN IN "0" POSITION THE RELEVANT SWITCHES.
Push buttons mode (switch 3)
Dip switch 3 is set at the factory on "0" position. This means that the
external push buttons perform the zero/span adjustments. If the user
puts this switch on "1" position, the zero push buttons will modify the
PV Bias-Offset and the span push button will reset the PV Bias-Offset
value.

4.6.4 FOUNDATION Fieldbus

There are 4 dip switches located on this kind of secondary electronics
(as indicated by the figure); they are used for settings when integral
display is not available.
Switch 1 and 2 allow the REPLACE MODE for sensor or secondary
electronics.
Switch 3 identifies the external push buttons functionalities: Zero/Span
adjustments or PV Bias-Offset / PV Bias Reset.
Switch 4 for performing the Simulation mode. The electronic label
clearly explains how to perform all the possible selection, but please
remember that all the operations with the dip switches should be
carried out when the transmitter is powered off so as to upload new
configurations at instrument start-up.
Replace mode (switch 1 and 2)
Usually switches 1 and 2 are down in "0" position.They are moved
when a replace operation is required. Switch 1 up in "1" position is
required before power up the transmitter, when user needs to replace
the electronics or the sensor.
Switch 2 down in "0" position allows the replace of the secondary
electronics. It must be moved in this position before power up the
transmitter. Switch 2 up in "1" position indicates that a new sensor
has been installed.
AFTER ANY REPLACE OPERATION IT IS RECOMMENDED TO MOVE
DOWN IN "0" POSITION THE RELEVANT SWITCHES.
Push buttons mode (switch 3)
Dip switch 3 is set at the factory on "0" position. This means that the
external push buttons perform the zero/span adjustments. If the user
puts this switch on "1" position, the zero push buttons will modify the
PV Bias-Offset and the span push button will reset the PV Bias-Offset
value.
Simulation mode (switch 4)
Dip switch 4 in "1" position enables the Simulation mode. This feature
is available in order to initialize all the parameters requiring a well
defined value, with the default values congruent to the connected
sensor type/model. This operation can be performed before powering
on the device. Many variables of the AI and TPB are properly set with
values strictly related to the connected transducer type.
4.7 Easy set-up
The easy set-up procedure is made possible thanks to the intuitive
HMI, connected on the transmitter communication board. To navigate
the 266 HMI please follow the various indications that will appear on
the bottom of the display.
To facilitate commissioning the 266 HMI has the capability to run a
sequence of predefined setup steps with the main configuration
settings. When you start the Easy Setup you must continue up to the
end to exit.
4.7.1 To start the Easy Set-up
Navigate the Digital LCD Integral Display menu, push the button on
the right under the LCD display.
