9.4 Hazardous movements
danger
attention
Hazardous malfunctions may be caused by failure to control a connected motor correctly. This may
be the result of various causes:
•
Improper or incorrect wiring;
•
Incorrect use of components;
•
Sensor and transducer faults;
•
Faulty components;
•
Software faults;
Such malfunctions may occur immediately after switching on or during operation. Monitoring
driven components excludes any predictable malfunction but is not sufficient in order to safeguard
safety, especially as regards the prevention of damage or injury. It is, therefore, necessary to
provide safety systems that are triggered should the motor fail to start and / or take possible
uncontrolled movements of the motor into account.
To avoid accidents, injuries and / or damage:
•
Do not allow personnel to approach the machinery or any moving parts. Possible
methods to prevent unauthorised access include:
o
safety rails;
o
safety gate;
o
safety cover;
•
Rails and barriers must be designed to counter the maximum potential kinetic energy.
