Operation
LCD display
For PGX100/PAX100 models, when in operating mode, the
device shows respectively "Z-S" on the left and configuration
menu icon on the right side of the display. Pressing left button
for approximately 3 s leads to the sub-menu for Zero and Span,
showing letters Z and S respectively in the left and right
bottom corners.
Zero trim can be performed by pressing the left button again.
A confirmation to proceed is subsequently requested by
pushing on the opposite button.
With the same logic but pressing the right button in the Z-S
sub-menu page, user can perform Span adjustment. A
confirmation to proceed is subsequently requested also for
Span.
In order to access the sub-menu for configuration and
diagnostic, press the right button for approximately 3 s from
operating mode view.
Press then for 2 s the right button to access the menu or press
the left button to access signals view or diagnostic messages.
Without action on buttons associated to bottom icons after
few seconds the transmitter returns to normal display view.
Local diagnostic menu
From the operating mode view, press the right button for
approx. 3 s, then pushing the left button, the display enters in
the local diagnostic menu displaying the status and device
health.
When no errors are active, it appears the string "All Alarms
Clear".
When one or more error conditions are active at the same time,
on the left side it is displayed the NAMUR Classification icon of
the most severe condition while, in the right side, is displayed
the error code plus a short textual description and a brief
suggested action about how it could be fixed.
The error code is the combination of the letter relating its
NAMUR NE107 classification (F, M, S, C) assigned by the
manufacturer at each individual error, plus its internal priority
number and a three digits code.
If more errors are active together, they are displayed into
this page according to their priority. They can be
visualized by scrolling down the screen with the left
button assuming the function of "Next" and their order is
indicated by the bar and number on the right side of the
display.
LCD menu structure
PGX100/PAX100 models feature 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 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).
IMPORTANT
After 50 seconds without action on on-board buttons, the
transmitter automatically exits the configuration menu.
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 PGX100/PAX100 pressure
transmitter. The menu driven structure will guide you to the
choice of the interface language, the tag number, the
engineering units, the LRV and URV (lower range value and
upper range value), the transfer function (linear or square root),
the damping time, the display visualization mode (the values
that need to be visualized on the LCD), the auto set zero (set the
input measured value to 4 mA and the PV value to 0), the RESET
PV bias (removes any previously configured bias values), the
contrast.
