10 HMI Local Indicator

The 266 PdP is available with the integral HMI LCD local
indicator with 4 buttons keypad as optionally item connected
on the communication board. There are two types of available
HMI:
— Conventional version (L1 option)
Gain access to the display by unscrewing the windowed cover.
Please observe the Hazardous area prescription before
proceeding with the cover removal. The keypad operability
doesn't require any activation procedure.
— TTG (Trough The Glass) version (L5 option)
The TTG technology allows the user to operate on the keypad
of the HMI without the need of opening the windowed cover of
the transmitter. The capacitive pick-ups will detect the
presence of your finger in front of the respective button
activating the specific command. At the transmitter power-on
the HMI automatically calibrate its sensitivity, it is mandatory for
the proper functioning of the TTG HMI that the cover is properly
tightened at power-on. In case the cover has been removed to
access the communication board, it is recommended to power
off and power-on again the transmitter once the windowed
cover has been set in place and properly tightened. For safety
reasons the keypad needs a specific activation procedure
before to became usable.

10.1 Installing / Removing the LCD display

1. Unscrew the housing cover of the communication board/
LCD side.
Important. With an Ex d / Flameproof design, please refer to
the section „Securing the housing cover with Ex d".
2. Attach the LCD display. Depending on the mounting
position of the pressure transmitter, the LCD display may
be attached in four different positions. This enables ± 90 °
or ± 180 ° rotations.
Important. Retighten the housing cover until it is hand-tight.
Important. If necessary, refer to the section „Securing the
housing cover with Ex d".

10.2 Integral display rotation

In case an optional integral display meter is installed, it is
possible to mount the display in four different positions rotated
clockwise or counterclockwise with 90° steps.
To rotate the LCD, simply open the windowed cover
(Hazardous area prescriptions must be respected), pull-out the
display housing from the communication board.
Reposition the LCD connector according to the new desired
position. Push back the LCD module on the communication
board. Be sure that the 4 plastic fixing locks are properly in
place.

10.3 Operations

The HMI is a Dot matrix LCD with a keypad of 4 buttons usable
for different purposes.
— Variable Indicator
— Diagnostic Indicator
— Feedback of the local push button operations
— Configuration tool

10.3.1 HMI as variable indicator

This is the normal way of how the HMI works. It is refreshed
every 2 seconds and can visualize the process measured
variables as well as other variables calculated every loop in the
PTRB and AIs. The HMI can be set to four different operating
Modes:
One line Only one variable with its unit code is displayed
One variable with its unit code is displayed and another
One Line and
variable can be selected to be displayed in percentage by
bar-graph
the bar-graph
Two variables with unit code are displayed together (one
Two Lines
for each line)
Two variables with unit code are displayed together (one
Two Lines and
for each line) and another variable can be selected to be
bar-graph
displayed in percentage by the bar-graph
The Mode selection can be done through the remote setting of
the HMI_MODE parameter or locally from the HMI menu
"Display/Settings/Mode".
