Reer EOS2 A Manual page 31

In any case, if a system stoppage occurs, switch the system off and on again to check
whether the incorrect behaviour of the system is to be ascribed to transitory
electromagnetic disturbances.
If the malfunction persists:
• Check that electrical connections are correct and undamaged;
•
Check that supply voltage levels comply with those indicated in the technical data.
•
Check that 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 that of
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 this, stop the
machine and contact the Reer 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 REER laboratories, clearly indicating:
•
product code number (P/N field shown in the product label);
• serial number (S/N field shown in the product label);
•
date of purchase;
•
