Selection and Qualification of Personnel
Important!
All configuring, programming, installation, commissioning,
operation and maintenance work on the automation system must
be carried out by trained personnel such as electricians or
electrical engineers. Personnel responsible for configuring and
programming the system must be familiar with all safety-related
issues in automation technology.
System operators must be instructed on the operation of the
control system and be familiar with the relevant operating
instructions.
All personnel responsible for installing, commissioning and
maintaining the system must have had appropriate training
qualifying them to work on automation systems.
1.3
Configuring, Programming, Installation, Startup and Operation
The automation system will in most cases be a part of a larger system
in which machines are controlled. When configuring, installing and
commissioning automation systems to control machines the machine
manufacturer and the user must observe the safety regulations as
defined in the machinery directive 98/37/EC or 2006/42/EC . For
specific applications national accident prevention regulations such as
VBG 4.0 will apply.
Safety-related components on the controlled machine must be
designed such that they operate independently from the control
system. Emergency stop components must remain operative in all
operating modes of the controller. In an emergency stop the power
supply to all switching elements controlled by the control system must
be brought to a safe state.
Measures must be taken for restarting an interrupted control program
following voltage dips or power failures. Operating conditions should
never cause danger, not even for a short time. In the event of danger
the emergency stop must be immediately triggered.
In order to prevent an open-circuit in the signal circuit causing non-
controllable conditions in the control system, the relevant hardware
and software safety precautions must be taken for I/O interfacing.
Control elements and their assigned control panel elements must be
installed in a place where they are sufficiently protected against
inadvertent use.
