S5-115F Manual

System Overview
1.1
Areas of Application
The S5-115F programmable controller is used in the most varied industrial fields. The following are
the main areas of application:
•
Safety-oriented applications requiring official authorization
(e.g. burner controls, cable-car controls, fairground carousels)
•
Applications not requiring official approval but constituting a high degree of danger for per-
sonnel and environment (e.g. controls for chemical processes)
•
Applications with high capital risk (e.g. controls for processing expensive materials).
1.2
Regulations for Applications Requiring Official Approval
The failsafe S5-115F has been prototype-tested by the Bavarian Technical Inspectorate (TÜV). The
prototype test covers a range of different regulations laid down by the various supervisory bodies
and professional associations.
The S5-115F meets the requirements for safety-related applications
•
with TÜV safety class 2
•
with quality level 6 to DIN V 19250
TÜV safety classes
The Technical Inspectorate (TÜV) has arranged the requirements laid down in the regulations into
five safety classes with the strictest requirements in safety class 1. It should be noted that the
safety class is not necessarily an indication of the risk involved in the areas of application in
question.
The S5-115F PLC meets the requirements of all regulations belonging to safety class 2 of the
Technical Inspectorate. This means that the regulations of safety classes 3 to 5 are also met:
Class 2:
-
Elevator controls to TRA 200/101
-
Escalator controls (not to EN 115)
Class 3:
-
Road traffic signal systems to DIN 57832/VDE 0832
-
Electrical equipment of furnaces to DIN 57116/VDE 0116
-
Telecontrol installations for gas and oil pipelines to TRGL 181
-
Fairground carousels (present plants)
-
Cable-car controls
Class 4:
-
Electromedical equipment to DIN IEC 601/VDE 0750
-
Remote radio control for cranes to ZH1/547
-
Manufacturing and processing machines to DIN 57113/VDE 0113
-
Flame monitoring equipment
-
Lifting platforms to VBG 14
Class 5:
-
Powered gates (controls)
Quality levels to DIN V 19250
The classification to DIN 19250 is not based on existing regulations but rather uses risk parameters
to define the risk inherent in a process. Risk parameters are the degree of damage, duration of
stay in danger areas, the possibility of avoiding danger and the probability of undesired states
arising. The risk graph gives information on the quality level in the case of protection facilities for
measurement, open-loop control and closed-loop control.
