9.5 Acceptance test

9.5 Acceptance test
9.5.1 General information
The requirements associated with an acceptance test can be derived from the EU
Machinery Directive. Presently IEC 22G WG 10 is working on a standard for "func-
tional safety". This also includes a specific description of the requirements for an
acceptance test. Accordingly, the machine manufacturer (OEM) is responsible for
the following:
S to carry out an acceptance test for safety–related functions and machine parts,
and
S to issue an "Acceptance certificate" that includes the results of the test.
When using the Safety Integrated function, the acceptance test is used to check
the correct configuring of the SI monitoring functions used in the NCK, PLC and
drive. The test objective is to verify proper implementation of the defined safety
functions and of test mechanisms (forced checking procedure measures) and to
examine the response of specific monitoring functions to the explicit input of values
outside tolerance limits. This should be carried out for all safety functions, i.e. for
the axial monitoring functions, the SPL, the safety–related communication relation-
ships, the safety–related I/O etc.
Warning
!
The acceptance test is used to check that the safety functions have been correctly
parameterized. Using the acceptance test, potential configuring errors are to be
identified and the correct configuring documented.
The measured values (e.g. distance, time) and the system behavior determined
(e.g. initiating a specific stop) when carrying out the acceptance test are used to
check the plausibility of the configured safety functions. The measured values that
are determined are typical and are not worst–case values. They represent the
behavior of the machine and the instant in time that the measurement is carried
out. These measurements cannot be used to derive maximum distances for
over–travel.
Warning
!
If machine data for SI functions is changed, a new acceptance test must be
carried out for the modified SI function and recorded in the acceptance report.
