Rules for Failsafe Operation of an S5-95F
Safety-related systems are divided into
•
Systems requiring no acceptance test
and
•
Systems requiring an acceptance test
The operator is himself responsible for systems not requiring an acceptance test, whereas those
requiring an acceptance test are examined by independent experts.
The procedure described in the following is intended as a guideline for the system acceptance test,
regardless of whether that test is carried out by an expert or by the operator himself.
The S5-95F is a component of your failsafe system. For this reason, the acceptance test also
includes configuring and the S5-95F user program.
Of the utmost importance to the S5-95F acceptance test is the failsafe interplay between all safety-
oriented components, such as sensors and actuators.
This section provides
•
A guideline for the acceptance test for a failsafe system
•
A summary of the topics covered, including added information for the inspection.
18.1
Acceptance Test for a System Containing an S5-95F
Experience has shown that an approval test is best divided into three phases. For this reason, we
would suggest dividing the acceptance test into
•
A planning phase
•
A pre-acceptance inspection
•
A system acceptance test
The approval procedure is dependent on the automated process, and is thus individual to each
system. In the sections to follow, we would like to provide a guideline to simplify your preparations
for the approval procedure.
