6.1 Installation instructions
The following conditions are to be ensured before installation of the photoelectric
safety sensors:
• The degree of protection of the electro-sensitive equipment (ESPE) has to
correspond with the risk assessment of the machine to be monitored�
• The safety system ensures a safety function and is not required for the
operation of a machine�
• It must be possible to stop any hazardous motion of the machine immediately�
In this respect the shutdown delay of the machine has to be determined�
• The object to be detected must be greater than or equal to the resolution of the
photoelectric safety sensor�
Install the photoelectric safety sensors so that the hazardous area can only
be accessed via the protected area� Depending on the application other
mechanical protective equipment may be necessary�
The operating conditions at the mounting location must not affect the functioning
of the photoelectric safety sensors� Please note especially:
• The transmitter and the receiver must not be affected by intensive light sources
(emitters, sunlight etc�)�
•
The operating temperature must be within the range indicated (→ 12 Technical
data)�
• Fogging of the lenses due to considerable temperature fluctuations can affect
the functioning of the photoelectric safety sensors� Take appropriate measures
to prevent this�
• Certain operating conditions can affect the functioning of the photoelectric
safety sensors� For mounting locations where fog, rain, smoke or dust may
occur, it is recommended to take appropriate measures�
• The standards EN 999 and ISO 13855 must be adhered to�
