VEGA VEGASON 66 4 … 20 mA_HART four-wire - Manual (Page 44)

8.3 Exchange the electronics module
If the electronics module is defective, it can be replaced by the
user.
In Ex applications, only an instrument and an electronics
module with appropriate Ex approval may be used.
If there is no electronics module available on site, one can be
ordered from the VEGA agency serving you.
The order data of the sensor must be downloaded into the new
electronics module. This can be done:
l
at the factory by VEGA
l
or on site by the user
In both cases, the sensor serial number is necessary. The
serial numbers are stated on the type label of the instrument or
on the delivery note.
Information:
When loading on site, the order data must be downloaded from
the Internet (see Operating Instructions manual "Oscillator").
The oscillators are adapted to the respective sensor and differ
in their signal output or in their power supply. You can find a
suitable oscillator in the following overview.
Oscillator SN-E.64V is suitable for VEGASON 64, 65, 66 -
