Troubleshooting and Maintenance
The LSP does not require any specific maintenance; however, it is good practice to clean the
front protective surfaces of the mirrors of the emitter and receiver. Clean with a damp cloth; in
very dusty environments. Never use abrasive or corrosive products, solvents or alcohol that
could damage the part to be cleaned. In any case, if a system stoppage occurs, switch the
system off and on again to check the incorrect behaviour of the system.
If the malfunction persists:
Check if the electrical connections are correct and undamaged.
„
Check if the power supply complies with the technical data.
„
Check if the emitter and the receiver are correctly aligned and that front surfaces are perfectly
„
clean.
It is advisable to keep the power supply of the light curtain separate from other electric power
„
equipments (electric motors, inverters, frequency variators) or other sources of disturbance.
If it is not possible to trace the cause of the malfunction and eliminate it, stop the machine
and contact the WEG assistance service. If the checks suggested are not sufficient to restore
the correct operation of the system, please send the device, with all its parts, to the WEG
laboratories, clearly indicating:
Product code number (P/N field shown in the product label).
„
Serial number (S/N field shown in the product label).
