4.2 Operating entity of the machine
DANGER
H
azard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
b
Changes to the electrical integration of the safety system in the machine control
and changes to the mechanical mounting of the safety system necessitate a new
risk assessment. The results of this risk assessment may require the entity operat‐
ing the machine to meet the obligations of a manufacturer.
b
Changes to the safety system’s configuration may impair the protective function.
The effectiveness of the safety system must be checked after any change to the
configuration. The person carrying out the change is also responsible for maintain‐
ing the protective function of the safety system.
4.3 Design
This chapter contains information about implementing the design of the safety system.
An
y design-related contents of the relevant operating instructions also apply. The follow‐
ing information is provided in the operating instructions for the linear measurement
sensor:
•
Bar code tape variants
•
Mounting of the bar code tape
4.4 Integrating the equipment into the electrical control
NOTE
Se
veral safety functions are generally necessary in order to ensure a safe design for the
entire application. This requires additional components that are not part of the safety
system, such as switches, fuses, and contactors. The circuit diagrams contain informa‐
tion on wiring the safety system with additional components within an application.

For the detailed pin assignment of the safety controller, see "Safety controller pin
assignment", page 26.
4.5 Testing plan
The safety system must be thoroughly checked by appropriately qualified safety person‐
ne
l during commissioning, after changes at regular intervals.
The regular thorough checks serve to assess the effectiveness of the safety system and
to identify defects as a result of changes or other influences (e.g., damage or manipula‐
tion).
The manufacturer and user must define the type and frequency of the thorough checks
on the basis of the application conditions and the risk assessment. Determination of
the thorough checks must be documented in a traceable manner.
