Festo P.BE-CMMP-AS-3A-HW-EN 0708NH

Causes
-
Unsafe or faulty circuitry or cabling
-
Faults in operating the components
-
Faults in the measured value and signal encoders
-
Defective or non-EMC conformant components
-
Errors in the software of the higher-level control system
These faults can occur immediately after the device is switched on or after a certain period
of operation.
The monitoring functions in the drive components exclude to a large extent the possibility
of incorrect operation of the connected drives. With regard to the protection of human
beings, especially the danger of bodily injury and/or material damage, one must not rely
on these circumstances alone. Until the fitted monitoring functions become effective, you
must reckon with at least one incorrect drive movement, the extent of which depends on
the type of control and on the operating state.
Warning
DANGER!
Dangerous movements!
Danger of injury or death, serious bodily injury or material damage!
For the above-mentioned reasons, the protection of human beings must be ensured with
the aid of monitoring systems or by measures which are of higher order than the system.
These measures are foreseen depending on the specific features of a danger and fault
analysis by the system manufacturer. The safety regulations applicable to the system must
be observed here as well. Undesired movements of the machine or other incorrect func-
tions can occur as a result of switching off, avoiding or failing to activate safety devices.
2.4.6
Protection against touching hot components
Warning
DANGER!
Surfaces of the device housing may be hot!
Danger of injury! Danger of burning!
Warning
Danger of burning!
Do not touch the surface of the housing in the vicinity of hot
sources!
After switching devices off, leave them for 10 minutes to cool
down before touching them.
If you touch hot parts of the device such as the housing which con-
tains the heat sink and resistors, you may burn yourself!
