The tester must validate all configured data in the configuration report by
checking all set limit values of the monitoring functions used are checked
by means of a function test.
The practical procedure of validation should be carried out directly on the machine or plant
to be protected. At least the following documents should be available for the validation:

Operating instructions of the machine or plant with warnings

Circuit diagram of the entire control system

Documentation of the planning of the safety-related part of the plant as described above.

Configuration report in electronic or printed form
The specific procedure should be based on the following guidelines:
a. The connected components such as control devices, sensors and actuators should be
checked for correct connection. This check should be done primarily by actuating /
stimulating the sensors and checking in the status display (diagnostics) of the safety
controller.
b. When using diagnostic functions e.g. pulse assignment, a check should be carried out e.g.
by short-circuiting him pulses etc.
c. If safety functions are used which are based on speed and/or position data, the correct
recording of the speed or position must first be checked. The check is possible e.g. by the
diagnostic function for speed and position which can be selected in the SafePLC. Here the
displayed velocity / position is to be checked by a physical measurement with a suitable
device. This test must be carried out in any case and is a prerequisite and cannot be
replaced by a theoretical test.
d. It is recommended to also check the diagnostics of the speed and position sensors. This
can be done, for example, by disconnecting a sensor or a track of a sensor.
e. The logic functions should be checked in relation to the planning specifications. This should
be done primarily by appropriate stimulation of the inputs etc. and the effect checked e.g.
activation of a monitoring function or also deactivation of an output.
f. The set parameters of monitoring functions should not only be checked for compliance with
the planning specifications, but also as far as possible by exceeding the parameterized limit
value and observing the reaction.
