Safety 

1.1

 

Intended Use 

The LVMC digital light curtain is a sensor for detecting, counting, measuring and classifying arbitrary objects. 
Use the device only for the purpose stated in this documentation. At any time, the light curtain may only be 
used within the limits of the prescribed and specified technical data and operating conditions. 
The light curtain is particularly not suitable for subsequent applications: Under water, in potentially explosive 
areas, in hot (more than +50°C) or cold (less than 0°C) areas, in condensing humidity, and in areas with flying 
sparks. 
The light curtain must not be used in safety applications, in particular not to protect against personal injury. It 
must not be used as a safety component in accordance with the EU Machinery Directive. 
In the event of improper use, modification or manipulation, any warranty is void, and any responsibility and 
liability of OPTRONIC AG for any damage or consequential loss caused thereby is excluded. 
Only use original OPTRONIC AG accessories or accessories recommended by OPTRONIC AG. Read the rele-
vant documentation carefully before putting the device into operation. 
The operator of the system in which the light curtain is integrated is responsible for compliance with national 
and international safety and accident prevention regulations (e.g. EN292, EN60204). 

1.2

 

Safety Instructions 

1.2.1

 

General Safety Instructions to Protect Against Physical Damage 

The instructions for the power supply must be observed. No other type of power supply than that described 
in this manual may be used 
All cables must be routed in such a way that nobody can step on them or trip over them 
Work on electrical equipment poses a safety risk and must be specially secured. The light curtain may there-
fore  only  be  installed  and  connected  by  a  specialist  in  a  voltage-free  state.  During  this  time,  the  machine 
must be switched off and secured against being switched on again. 

1.2.2

 

General instructions to Avoid Damage to the Device 

In case of faulty connection with other devices or a faulty power supply, there is a risk that the light curtain 
will be damaged. Read the relevant instructions before establishing the connection and read the documenta-
tion before commissioning.
