6.3.6 BLOCK_ERR
BLOCK_ERR presents the cause of an error in the
block. The SENSOR transducer block checks the
following causes and sets the relevant bits.
BLOCK_ERR
Bit Error Cause
1 other Differential pressure adjusted
by zero/span adjustment out
of measurement range, Static
pressure adjusted by zero/span
adjustment out of measurement
range
7 other Pressure sensor failure, Capsule
temperature sensor failure
13 other Electronic circuit failure
15 Out-of-Service MODE_BLK.Target is O/S
6.3.7 XD_ERROR
XD_ERROR is a parameter that contains codes
for the most significant errors that can occur in the
SENSOR transducer block. The errors of XD_
ERROR supported by transmitter and their causes
are presented in the table below. When multiple
errors occur and their error codes are different, the
error with a larger code value is stored first.
XD_ERROR
Bit Error Cause
15 Out of Service Sensor TB is in O/S mode.
18 Calibration
error
An error occurred during
calibration or a calibration error
has been detected.
20 Electronics
Failure
An electronic component has
failed.
22 I/O Failure An I/O failure has occurred.
6.4 LCD Transducer Block
6.4.1 Outline of the Functions
The LCD transducer block controls alarms and
measured values that are displayed on the integral
indicator. It displays not only OUT signals from the
AI blocks, but also I/O signals of the Installed blocks
on the integral indicator.
6.4.2 Block Mode
The Block modes permitted for the LCD transducer
block are Automatic (Auto) and Out of Service (O/
S). Settings can be changed in the AUTO mode for
this block, except the Block tag parameter.
6.4.3 Display Contents of the Integral
Indicator
The components of the integral indicator are the bar
graph, the title field, the center field for numerical
values, the lower text field, and auxiliary characters.
The contents and meanings of these components
are as follows:

Bar graph Shows the value displayed in the center
field for numerical values scaled in terms
of percentage.
Center field
for numerical
values
Presents values of inputs and outputs.
While the alarm is on, the alarm number
alternates with the displayed value here.
Lower text
field
Displays tag, parameter name, unit, and
signal status. While the alarm is on, the
alarm contents alternate.
Title field Depicts the type of the value displayed
on the center field for numerical value.
P
Flashes when pressure/
differential pressure is
displayed.
SP Flashes when static pressure is
displayed.
T Flashes when temperature is
displayed.
Auxiliary
characters
% Flashes when the center field
for numerical values displays a
% value.
Flashes when square root
display is selected.
Key
mark
Flashes when Write Protect is
selected.
Ч10,
Ч100,
Ч1000
Used when the calculated value
displayed in the center field for
numerical values is rounded.
