Menu 6: Modification of the measuring
range (RANGE)
The FCX-AII pressure transmitters
intended for use in nuclear power
plants are delivered configured
with an enabled write protection.
The configuration of the measuring
range of the device 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.
This menu allows the following values to be
configured for the transmitters:
-
LRV

-

The measuring range can be adjusted:
Note
:
If the selected measuring range exceeds the
authorised limits, “SETTING ERR” (error of
adjustment) appears on the lower line of the display.
The maximum range is ±9999
If the unit is modified, the URV value may exceed
the upper limit. If this occurs, change the URV first.
- Press <CHNG>on screen 1. The screen to change
the LRV or URV values appears.
- Press <LRV> to modify the 0% (screen 3 )
- Press <URV> to modify the 100% (screen 4 ).
- Under screens 3 or 4 , enter the corresponding
values for the 0% or 100%.
Press <ENT> to validate.
Menu 5: Limitations of the measuring
range (RANGE LIMIT)
A modification of this value URL (Upper Range limit)
is not possible by the user because it is linked to the
maximum measurement range that corresponds
to the measuring cell of the transmitter.
- To display the menu <RANGE>, press the
<INC> key.

Note: If the value of 0% or 100% is outside the
measurement range, an error appears, saying
“setting error” . In this case, please change the
measuring range (LRV and/or URV)
- After having confirmed the change, screen 1
appears, then press <INC> to obtain the following
menu: DAMPING.
The measuring range of the
transmitter is independent of the
measuring range of the indicator.
After the measuring range has been
changed in this menu, the measuring range of
the LCD indicator must be changed (menu G).
If the transmitter is equipped with an analogue
indicator and the measuring range must be changed,
the analogue indicator must also be changed.
