TROUBLESHOOTING
The instructions provided by the LEDs of the Emitter and the Receiver enable the user to
identify the cause of a number of system malfunctions.
Refer to figure 22 to verify the LEDs indications.

In any case, when faced with a system stoppage, switch the system off and then on again, to
exclude any occasional electromagnetic disturbances. In case of continued malfunctioning:
•
verify the integrity of electrical connections and check that these have been made
correctly;
•
check that the supply voltage levels comply with those specified in the technical
data sheet;
•
the barrier power supply should be kept separate from that of the other electric
power equipment (electric motors, inverters, frequency converters) or other
sources of disturbance.
•
make sure that the Emitter and the Receiver are correctly aligned and that the
front surfaces are perfectly clean.
