7 Maintenance Instructions
7.1 General Maintenance
The SafEye system requires only simple periodic maintenance to provide
satisfactory service and achieve maximum performance. The detector and
source units can be maintained with the use of common tools and
equipment. Record the periodic test results in a maintenance logbook with
a copy of the delivery form inside.
Note: The maintenance can be performed through RS-485. For more
details, refer to Manual TM899050 .
7.2 Periodic Maintenance
It is recommended to perform periodic cleaning of optical surfaces.
Note: The frequency of cleaning operations is ultimately dependent upon
the existing environmental conditions and the applications used.
• Proper maintenance will allow the SafEye system to retain maximum
performance and reliability.
• The optical surfaces of the source and detector viewing windows
should be kept as clean as possible as it is an active device.
• Alignment procedures must be performed each time that the source or
the detector unit has been opened or moved for any reason.
• The Signal Verification Check corroborates the current signals from the
light source compared to that of previous alignments. It is
recommended to perform this check every 6
– 12 months. The signal
should be checked according to threshold levels (see Signal Verification
on page 60).
• The functional check should be performed every 6 months (see
Functional Check of Unit on page 56).
• Zero calibration (see Zero Calibration on page 56) must be done every
time the detector or source is realigned or windows cleaned.
