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
-
ics modules are adapted to the respective sensor and differ in signal
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.
When loading on site, the order data must first be downloaded from
the Internet (see operating instructions manual "
Electronics module
").
Caution:
All application-specific settings must be entered again. That's why you
have to carry out a fresh setup after exchanging the electronics.
If you saved the parameter settings during the first setup of the sen
-
sor, you can transfer them to the replacement electronics module. A
fresh setup is then not necessary.
