General instructions

We recommended installing the replacement electronics with the
instrument dismounted and brought to a suitable place, e.g. a work-
shop. If it is not possible to dismount the instrument, the electronics
module can also be installed on site at the measuring point.
Warning:
Switch off voltage supply before starting the installation procedure.
The replacement electronics may only be installed when the sensor is
in a de-energised state. Non-observance will damage the electron-
ics!
It is absolutely necessary that the following points are observed with
sensors with Ex approval:
For sensors with Ex approval, make sure that the replacement elec-
tronics module has the same designation as the exchanged electron-
ics module.
For example, an electronics module with a hardware version ≥ 2.0.0
must be only installed in a sensor with hardware version ≥ 2.0.0.

Mounting preparations

The electronics modules are mounted in the electronics compartment
and adapted to the respective sensor. First of all, check by means of
the following lists if you are using a suitable electronics module.
•
FX-E.80H for version 4 ... 20 mA/HART (two-wire/four-wire/Mod-
bus)
•
FX-E.80A for version 4 ... 20 mA/HART with SIL qualification
•
FX-E.80P for version Profibus PA
•
FX-E.80F for version Foundation Fieldbus
With SIL qualified instrument, only a respective electronics module
with SIL qualification must be used.
Electronics modules for SIL qualified instruments can only be ordered
by stating the sensor serial number. Have the sensor serial number
ready when ordering.
