In any case, when faced with a system stoppage, switch the system off and then on again, to
exclude any occasional electromagnetic disturbances.
Should the problem persist, contact REER’s service department. 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.
If it is not possible to clearly identify the malfunction and to remedy it, stop the
machine and contact Reer's Assistance Service.
If correct system operation cannot be restored after carrying out the above procedures, send
the equipment to REER’s laboratories, complete with all parts, stating clearly:
•
the product code number (the
P/N
field is shown on the product label)
•
serial number (the
S/N
field is shown on the product label)
•
date of purchase;
•
period of operation;
•
type of application;
•
fault.
