7.10 Activation procedure for LCDs
The LCD displays L1 and L5 features 4 push buttons (see
figure 19) that allow the navigation through the various
functions.
— Press simultaneously the buttons (2)
and (3)
until two icons will appear at the bottom corners of
the display.
— Press the button (4)
under the right icon within
one second to access the HMI menu or press the left
button (1)
to access the instantaneous diagnostic
messages.
For TTG display, in case of pressing not correct the
following display will appear with “!” marks in the corners.
Press then for 2 s. the right button or external S
pushbutton to access the menu or press the left button or
external Z pushbutton to access signals view or
diagnostic messages. Without action on buttons
associated to bottom icons after few seconds the
transmitter return to normal operation displaying letters
in the corners.
7.12 HMI menu structure
Standard HART version features only the Easy Setup menu
in a dedicated structure, different from other HART
versions. Once accessed the menu should be completed
until the last step HART Revision is reached, then to return
to the normal display view. For each step follow the
instructions on the screen and consider that for alfa/
numeric parameters it is required to move digit by digit
until the right bottom corner display OK. Pressing the
right on-board button or the external S pushbutton the
operation is confirmed, while pressing the left on-board
button or the external Z pushbutton the display change to
CANCEL to abort the operation by the associated button
(right/S).
7.8 Configuration of the pressure transmitter
using the optional LCD HMI with keypad (menu-
controlled)
The integral LCD option (L1 or L5 option) is connected on
the 266 Advanced HART communication board. It can be
used to visualize the process measured variables as well
as to configure the display and the transmitter.
In addition, diagnostic information is provided. To access
the functionality of the HMI an activation procedure
needs to be carried out. The keypad activation procedure
is different between the TTG (Through-The-Glass) L5
option and the conventional L1 option integral LCD.
Important. After 30 seconds without action on on-board buttons or
external Z/S pushbuttons, the Standard HART transmitter
automatically exit the configuration menu.
For Advanced HART and Safety HART versions the HMI
menu is divided in the following sections which can be
selected by acting on the keys (2)
and (3)
, once on
the display the desired sub-menu icon will be visualized,
confirm your selection with the [SELECT] key (4)
.
Follow the instruction on the screen to perform the
configuration of the different parameters.
This menu allows the verification and the
parameterization of the basic configuration of the 266
pressure transmitter. The menu driven structure will guide
you to the choice of the interface language, the tag
number configuration, the engineering units, the URV and
LRV (Upper range value and lower range value), the
transfer function (linear or square root) the damping
time, the auto set zero (set the input measured value to 4
mA and the PV value to 0), the display visualization mode
(the value that need to be visualized on the LCD).
This menu allows the verification and the parameterization
of the entire device The menu driven structure includes the
write protection enabling, process variable settings (unit,
LRV and URV), transfer function selection (linearization type
and low flow cut-off) and output scaling (unit according to
the measurement and LRV/URV). The last selectable sub-
menu allows user to reset all the parameters to the default
configuration.
This menu allows the set-up of different functions
relevant to the display itself. The menu driven structure
will guide you through the choice of some functional
aspects as the display language and contrast. Moreover,
it is possible to choose in details what you want to see on
the display: one or two lines with or without bargraph.
Inside this menu there is the possibility of setting a
protection password (security) and the display scaling
(linearization type, unit, LRV, URV). Display revision
number available.
