VEGA VEGADIF 65 Electronics module - Manual (Page 6)

4 Mounting
4 .1 General instructions
The pressure transmitters VEGADIF 65 are equipped with a two-part
electronics: the meas. cell and the processing electronics. The meas.
cell electronics in the process fitting is not accessible to the user. The
processing electronics, as an electronics module, is located in the
housing. In case of a defect, the electronics module can be exchanged
by the user.
In Ex applications only one instrument and one electronics module with
respective Ex approval may be used.
If no electronics module is available on site, it can be ordered from the
VEGA agency serving you. The order is possible without or with
sensor serial number. The serial number is stated on the type label of
the instrument or on the delivery note.
The electronics module without serial number contains no order-
specific data. However, operation of the instrument is also ensured
without these data. This allows a "universal electronics module" to be
kept in stock for several instruments.
The electronics module with sensor serial number contains order-
specific data such as housing material, process fitting, meas. cell
seal, etc.
4 .2 Mounting preparations
First of all, check by means of the order code if you are using the
suitable electronics module:
l Electronics module DF-E.60Z for all VEGADIF 65 4 … 20mA
l Electronics module DF-E.60H for all VEGADIF 65 4 … 20mA/
HART
l Electronics module DF-E.60P suitable for all VEGADIF 65 Profibus
PA
l Electronics module DF-E.60F suitable for all VEGADIF 65
Foundation Fieldbus.
4 .3 Mounting steps
The electronics module is located in the electronics compartment. The
below illustrations show the respective position of the electronics
compartment in a single or double chamber housing.
