3. Instructions for Use and Safety Precautions
3.1 General Instructions for Use and Safety Precautions
Observe the following points in order to assure safe use of the Safety Light Array for its intended purpose.
Applicable national and international requirements apply to installation and use of the Safety Light Curtain, as well
as to initial start-up and periodic technical testing, in particular:
• EN standards
• Accident prevention regulations
• Occupational health and safety requirements
• EU machinery directive
The manufacturer of, and the company who operates the machine at which the Safety Light Curtain is used must,
on their own initiative, agree upon and adhere to all applicable safety regulations and rules in cooperation with the
responsible authorities. It is absolutely essential to adhere to all directions included in these operating instructions,
in particular the inspection procedures.
Contactless safety devices may only be used at power operated machinery whose controls can be electrically
influenced such that hazardous motion can be stopped immediately in all operating phases.
Additional measures may be necessary in order to assure that the ESPE does not malfunction or fail in a danger-
ous fashion due to other types of light which are used in the respective application (e.g. resulting from the use of
cordless controllers on cranes, emission due to welding sparks or the effects of stroboscope light).
Testing must be performed by an expert prior to initial start-up of the ESPE. Testing must establish flawless
interaction of the ESPE together with the controls of the power operated machinery, and correct installation in
accordance with these safety precautions.
Testing must be conducted by qualified persons, or persons who have been authorized and engaged specifically
to this end, and must be documented in a fashion which can be readily retraced at any point in time.
The cascading terminals on the sensor and the receiver may only be used to connect additional Light Arrays.
Connection of other power consumers is impermissible.
Changes to device configurations may impair the respective devices’ protective functions. For this reason, the
effectiveness of the safety device must be retested each time its configuration is changed. The person who makes
the change is also responsible for assuring that the safety function of the device is maintained.
The operating instructions must be made available to the operator of the machine at which the Safety Light Array
is used. The machine operator must received instruction from qualified persons, and must be required to read the
operating instructions.
