The functional safety is already activated Ex factory for instruments
with SIL qualification. For instruments Ex factory without SIL qualifica-
tion, the functional safety must be activated by the user for applica-
tions according to SIL via the indicating and adjustment module. The
SIL factory setting cannot be deactivated by the user.
The activation of SIL has the following impact:
•
In the menu item " Failure mode " under " Current output ", the
parameters " Hold value " and " 20.5 mA " are blocked
•
In the menu item " HART mode ", the function " Multidrop " is
blocked
Note:
For such applications, it is absolutely necessary to take note of "
Safety Manual ".
HART offers standard and multidrop mode.
The mode "standard" with the fixed address 0 means outputting the
measured value as a 4 … 20 mA signal.
In Multidrop mode, up to 15 sensors can be operated on one two-wire
cable. An address between 1 and 15 must be assigned to each sen-
sor.
