7. Errors and Countermeasures
NOTE
For F

Fieldbus and PROFIBUS PA communication types, please refer to manuals in the attached CD-ROM.
The table below shows a summary of error messages for BRAIN and HART protocols.

Er. 01 CAP MODULE FAULT
Capsule problem.* 1 Outputs the signal according to
status of a burnout direction pin
or switch (the signal can be set as
“hold” for BRAIN protocol). Replace the capsule when
error keeps appearing even
after restart.*

er.
Er. 03 OUT OF RANGE
Input is outside
measurement range limit
of capsule. Outputs high range limit value or
low range limit value. Check input.
Er. 04 OUT OF SP RANGE
Static pressure exceeds
speci
fi
ed range.* 3
Displays present output. Check line pressure (static
pressure).
Er. 05 OVER TEMP (CAP)
Capsule temperature
is outside range (-50 to
130°C). Displays present output. Use heat insulation or make
lagging to keep temperature
within range.
Er. 06 OVER TEMP (AMP)
Ampli
fi
er temperature
is outside range (-50 to
95°C).
Displays present output. Use heat insulation or make
lagging to keep temperature
within range.
Er. 07 OVER OUTPUT
Output is outside high or
low range limit value. Outputs high or low range limit
value. Check input and range
setting, and change them as
needed.
Er. 08 OVER DISPLAY
Displayed value is
outside high or low range
limit value. Displays high or low range limit
value. Check input and display
conditions and modify them
as needed.
Er. 09 ILLEGAL LRV
LRV is outside setting
range. Holds output immediately before
error occurrence. Check LRV and modify as
needed.
Er. 10 ILLEGAL URV
URV is outside setting
range. Holds output immediately before
error occurrence. Check URV and modify as
needed.
Er. 11 ILLEGAL SPAN
SPAN is outside setting
range. Holds output immediately before
error occurrence. Check SPAN and change as
needed.
Er. 12 ZERO ADJ OVER
Zero adjustment is too
large. Displays present output. Readjust zero point.
*1: This error code appears at a capsule problem or when an illegal overpressure is applied to the pressure sensor.
*2: If the normal pressure is regained, the Er.01 will disappear according to the setting of the parameter of E50
：
AUTO RECOVER.
When the E50
：
AUTO RECOVER is set to ON, the Er.01 will disappear automatically. The default setting for this parameter is
ON. When the E50
：
AUTO RECOVER is set to OFF, restart the transmitter to cancel Er.01. If no error code appears then, perform
necessary adjustments such as zero-adjustment to continue the operation. If the error code still appears, replace the capsule
assembly.
*3: For Model EJA120A, static pressure cannot be measured. The display is always 0 MPa, but this is not a measured value.
