WARNING!
Failure of the control and impact on the process
Cause: If the controller or other parts of the meas‐
uring plate fail, then the process, in the bypass of
which the measuring plate is working, will no
longer be measured and regulated.
Possible consequence: Fatal or very serious inju‐
ries. The process, in the bypass of which the
measuring plate is working, will become out of con‐
trol and could cause harmful reactions.
Measure: It is the responsibility of the operator
and/or manufacturer of the entire system in which
the measuring plate is installed to take appropriate
measures to ensure that the failure of the meas‐
uring plate or of individual components of the
measuring plate do not have a damaging effect on
the entire process and/or the overall system.
These measures can include, for example:
–
Redundant design of the measuring and con‐
trol station.
–
Connection of an appropriate alarm device to
the measuring plate and/or the controller.
–
The alarm relay on the controller could be set
[fail save] and be evaluated as an overall
to
alarm for the process.
–
Installation of additional safety systems from
active or passive system components, with the
purpose of making the technical systems safer
for operators and users.
WARNING!
Operation in areas with an explosive atmosphere
Possibility of an explosion
Do not operate the systems in areas where there is
a risk of explosion. The system is not intended for
operation in areas at risk from explosion. The
system itself does not present a risk of explosion.
