The FCX-AII pressure transmitters
intended for use in nuclear power
plants are delivered configured with
an enabled write protection and with
an “OVERSCALE” output signal in the case of a
defect. The reconfiguration of the output signal if
the device has a defect must be done before the
write protection is lifted according to the provision
specified on page 35. After all the operations are
complete, the write protection must be replaced.
9-1 Change of the substitute value
After having pressed “CHNG ALHA” 1 , the
selection 2 can be:
1- Not USED (last output signal is maintained)
2- OVER SCALE (above the range of the signal)
3- UNDER SCALE (below the range of the signal)
By selecting <1>, <2> or <3>.
Press “ENT” to validate 3 and confirm 4 .
In mode NOT USED, press “CL” to exit. No
parameter is editable.
9-4 Change of the substitute value in UNDER
mode (UNDERSCALE)
This display appears when “UNDER” has been
selected.
To change the substitute value, press “CHNG
ALHA” and then increase or decrease the value
with “INC” OR “DEC”.
Validate and confirm with “ENT”.
Setting option:
3.2 mA ≥ signal of the substitute value (UNDER)
≥ current saturation value (lower limit) (refer to
page 34).
9-4 Change of the substitute value of
retrenchment in OVER mode (OVERSCALE)
This display appears when “OVER” has been
selected.
To change the substitute value, press “CHNG
ALHA” and then increase or decrease the value
with “INC” OR “DEC”. Validate and confirm with
“ENT”
Setting option:
Current saturation value (upper limit) ≤ signal
of the substitute value (OVER) ≤ 21.6 mA (refer
to page 34).

Note:
The current saturation value (high limit and low
limit) can be edited by following the “menu J:
current saturation value”.
The value of the low current saturation limit is
adjustable up to 4.0mA (between 3.2mA and
3.8mA).
The value of the high current saturation limit is
adjustable up to 21.6mA (between 20.0mA and
21.6mA).
