OPERATING MANUAL PSEN op4F/H-A series
1003067-EN-02 13
Example 4: Moulding machine
The moulding machine is used to create
complex shapes from metallic parts or parts
made from other materials. In this case it is
necessary to prevent the operator’s hands or
other limbs being dragged, entangled or cut
by the tool itself or being injured by the
spindle.
Solution: The safety light curtain from the
PSEN op4F/H-A series is the best solution
for protecting the operator in terms of the required safety level and the application type. As
soon as even a single beam on the light curtain is interrupted, the machine is stopped
immediately.
Benefits: The small dimensions of the light curtain with no dead zones guarantees maximum
flexibility during installation, as it can be adapted to the machine dimensions.
1.4 Safety information
To use the safety light curtains in the PSEN op4F/H-A series safely
and correctly, the following information must be considered:
• The system intended to stop the machine must be electrically controllable.
• This control system must be able to stop hazardous machine movements
- inside the overall stopping performance of the machine T,
- in accordance with the details in Chapter 1.2.3 of the operating manual (see CD provided)
- and in each phase of the processing cycle.
• The protective device must be positioned at a distance that exceeds the minimum safety
distance S or that corresponds to it, so that the operator cannot reach the danger zone until the
movement of the hazardous object has come to a standstill by triggering the light curtain.
• The safety light curtains may only be installed and connected by qualified personnel. It is
essential to follow the instructions provided in the relevant sections of the manuals provided
(see Chapters 2, 3, 4 and 5) and to comply with the applicable directives.
• Ensure that the correct operation of the light curtain is not disturbed by strong electromagnetic
interference.
• Ensure that the light curtain, particularly the receiver, is not installed close to particularly
intense and/or flashing light sources.
• The safety light curtain must be positioned so that it safely prevents access to the danger zone
without interrupting the beams (see Chapters 2, 3).
• Only qualified personnel with appropriate knowledge of all the operating procedures of the
safety light curtain should be permitted to work within the danger zone.
• The RESET button must be positioned outside the area of the protected field and in such a
way that the operator can see into the danger zone when carrying out a reset and test
procedure.
•
Reflective surfaces close to the beams emitted from the protective device (whether from
above, below or from the side) can cause passive reflections that adversely affect the correct
operation of the light curtain.
The instructions provided for correct operation must be strictly followed before switching on
the light curtain.
