Pilz PSEN op4F/H A Series Getting Started

of the PSEN op4F/H-A-series, the following instructions have to be observed.
• The system intended to stop the machine must be electrically controllable.
• The safety system at the machine must be able to stop any hazardous machine movement
− within the entire stopping time 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 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.
• The safety light curtain must be installed securely so that access the danger zone is not possible without
interrupting the light axes (see chapter 2 and 3 of the operating manual).
• 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 operating elements for the TEST, RESET/RESTART and OVERRIDE functions have to be arranged
outside the protected field, so that the operator can control the corresponding area at any time.
• Instructions provided for correct operation must be strictly followed before switching on the light curtain.
Precautionary measures when selecting and installing
Ensure that the safety level guaranteed by the light curtain is compatible with the actual hazard
of the machine to be monitored, in accordance with the standards EN 954-1 and EN 13849-1.
• The outputs (OSSD) of the light curtain have to be connected as safety inputs and not in the normal
control circuit. The machine must have a separate START control.
• The resolution of the light curtain has to be less that the objects to be detected.
• The light curtain must be installed in an environment that complies with the technical properties stated
in Chapter 10 "Technical data" of the operating manual (see CD provided).
• Avoid installing the device, particularly the receiver on the front, close to particularly intense and/or
flashing light sources.
• Strong electromagnetic interference could adversely affect the correct operation of the light curtain.
Consider this carefully, seeking the advice of Pilz's technical customer services.
• Smoke, mist or dust in the air in the working environment can reduce the operating range of the light
curtain considerably.
• Sudden, large-scale temperature variations with very low peak values can generate a slight layer of
condensation on the light curtain's lens, adversely affecting its function.
• 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 operation of the light curtain.
• The protective device must be positioned at a distance that exceeds the minimum safety distance S or
that corresponds to it, which guarantees that the operator cannot reach the danger zone until the
hazardous machine movement of the object has come to a standstill by triggering the light curtain.
When the safety distance is not maintained, the safety function of the light curtain could be
adversely affected or cancelled. A detailed description of the safety distance calculation is to be
