Changing the electronic insert
If the existing Smart electronic insert is to be replaced with another Smart electronic
insert, then it can be ordered under the following order No.:
- LHC-Z102: Electronics for Barcon, 4 mA ... 20 mA, HART protocol,
with sensor parameters
When ordering with this order No., please state the sensor number
of the instrument (given on the nameplate). Your electronic insert
is then reset in the factory to your sensor parameters
- LHC-Z101: Electronics for Barcon, 4 mA ... 20 mA, HART protocol,
without sensor parameters
When ordering with this order No. the electronic insert is
programmed with a default set of data, i.e. the instrument will
function, but with less accuracy. In order to restore the defined
accuracy, the new sensor parameters should be re-entered after
exchanging the electronic insert. All information on this is given in
subsection "Entering sensor parameters" in this section.
- After replacing the electronic insert the instrument must be recalibrated.
Information on adjustment is given in chapter 4 "Commissioning".
If the existing Smart electronic insert is to be replaced with an analogue electronic insert,
then the information contained in BA 200O, supplied with the analogue electronic insert,
applies.
