9.4 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-
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, first of all the order data must be downloaded
from the Internet (see operating instructions manual "Electronics
module").
9.5 Software update
The following components are required to update the sensor soft-
ware:
•
Sensor
•
Voltage supply
•
Interface adapter VEGACONNECT
•
PC with PACTware
•
Current sensor software as file
You can find the actual sensor software as well as detailed infor-
mation of the procedure under "www.vega.com/downloads" and
"Software".
You can find information about the installation in the download file.
Caution:
Instruments with approvals can be bound to certain software ver-
sions. Therefore make sure that the approval remains effective with a
software update.
You can find detailed information on www.vega.com/downloads and
