Intended Use
The c250-S Safety System comprising Safety controller c250-S, Safety I/O-module and
PLCDesigner Safety Software make the Safety I/O-module fit for the functional safety of
machinery.
The intended applications of the c250-S Safety System include safety functions of machines
and all industrial automation tasks immediately associated with them. Thus, the system may
only be used for applications providing a defined fail-safe state which, in case of the c250-S
Safety System, is a wattless state.
Running any of the safety-related control components is subject to the safety precautions
applicable to industrial control units, i.e. guarding by emergency stop and similar safety
equipment as specified by the relevant national and/or international regulations. The same
applies to connected equipment such as drives or light grids. Before installing and putting the
system into operation, the safety instructions, connection specifications (nameplate and
documentation) and the limiting values listed in this Operating Instruction's Technical Data
section must be read carefully and obeyed at any time.
The c250-S Safety System is not designed for applications causing potentially fatal risks or
dangers to the life and health of many persons or disastrous ecological hazards unless
exceptionally strict safety precautions are taken. Such applications specifically include the
monitoring of nuclear reactions in nuclear power stations as well as the control of flight or air
traffic control systems, means of mass transit, medical life support systems and weapon
systems.
4.2.2
Qualified Persons
The safety-related products may be used by the following persons only:
•
Qualified persons who know the applicable concepts of functional safety as well as the
relevant standards and regulations.
•
Qualified persons who plan, design, install and put machine and system safety equipment
into operation.
This manual's safety instructions construe qualified persons as persons whose training,
experience, instructions and knowledge of the applicable standards, codes, accident
prevention regulations and operating conditions authorise them to perform the required work
and enable them to recognise and avoid potential hazards associated with that work. Language
skills sufficient to understand this manual are therefore part of this qualification.
