9. DETECTOR MAINTENANCE AND CHECKS
9.1 CHECK TO CARRY OUT AFTER INSTALLATION
After configuring and calibrating the system, wait a minute of normal running and
then cover the reflective unit for 30 seconds with an opaque object of a suitable
size.
It is necessary in this state for the TRx unit to indicate a fault (yellow LED
steadily on), for the whole time the reflective unit remains covered. If
instead of indicating a fault for interruption of the beam, the system goes
or into alarm mode, or if it remains in normal working, it means that
there has not been compliance with the start conditions indicated on
page 8.
9.2 M AINTENANCE
The normal detectors installation conditions require the maintenance intervals
indicated in current law and regulations, to be carried out in accordance with
national standard.
These intervals, based on every 6 months, may in some cases have to be more
frequent where there are multiple applications for the detector, especially in
industrial environments where there is dust or hanging vapours or products of
particular processes.
The maintenance of the ILIA-OZ detector does not require special equipment and is
simple and fast.
These operations are carried out with the following procedure:

Clean the detector with water and/or neutral soap without using abrasive
cloths, solvents or oils. Clean the front of the TRx and the reflective unit with a
soft cloth. If the surfaces are badly scratched, yellowed or have become
noticeably opaque, they must be replaced by qualified personnel as this correct
prejudice the proper optical of the detector.

It is necessary to replace detectors that are have mechanical damage or damage
to the optics, with new detectors.

Check for correct infrared signal level by means of the <adjustment> menu,
complying with the LED signals. In this case set the Rx level at 100% (see notes
on page 31). If the Rx value is too low repeat the alignment procedure until you
get to the excess sign and repeat the < AUTO Adjust> procedure..
