9.5 Exchanging the electronics module
If the electronics module is defective, it can be replaced by the user.
In Ex applications, only instruments and electronics modules with ap-
propriate Ex approval may be used.
If there is no electronics module available on site, the electronics
module can be ordered through the agency serving you. The electron-
icsmodulesareadaptedtotherespectivesensoranddierinsignal
output or voltage supply.
The new electronics module must be loaded with the default settings
of the sensor. These are the options:
•
In the factory
•
Or on site by the user
In both cases, the serial number of the sensor is needed. The serial
numbers are stated on the type label of the instrument, on the inside
of the housing as well as on the delivery note.
