7.1 General Maintenance
The SafEye Quasar 900 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 Maintenance Logbook
with a copy of the delivery form inside.
7.2 Periodic Maintenance
Recommended cleaning of optical surfaces to be performed periodically.
Note: The frequency of cleaning operations is ultimately dependent upon
the existing environmental conditions and the applications used.
➣ To perform periodic maintenance:
1 Proper maintenance will allow the SafEye system to retain maximum
performance and reliability.
2 The optical surfaces of the Source and Detector viewing windows should
be kept as clean as possible as it is an active device.
3 Alignment procedures must be performed each time that the Source or
the Detector unit has been opened or moved for any reason.
4 The Signal Verification Check corroborates the current signals from the
Flash 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,
page 39).
5 The functional check should be performed every 6 months (see
Functional Check of Unit, page 41)
6 Alignment procedure should be performed only if the signals are below
Threshold value (see Signal Verification, page 39)
7 Zero calibration (see Zero Calibration, page 40) must be done every
time the Detector or Source is realigned or windows cleaned.
