8 Maintenance Instructions
8.1 General Maintenance
Only basic periodic maintenance is required to keep the SafEye Quasar 950/960
at maximum performance and reliability levels. The detector and source units can
be maintained with the use of common tools and equipment. The test results
should be recorded in a maintenance logbook, together with a copy of the
delivery form.
8.2 Periodic Maintenance
The source and detector viewing windows should be kept as clean as possible, as
they are active devices. Perform proper maintenance procedures periodically to
allow the SafEye system to retain maximum performance and reliability.
Note:
The frequency of cleaning operations depends on the existing
environmental conditions and the applications used.
To perform periodic maintenance:
1
Perform alignment procedures each time that the source or the detector unit
are opened or moved for any reason.
2
The signal verification check corroborates the current signals from the UV
source compared to that of previous alignments. This check should be
performed every 6
– 12 months. The signal should be checked according to
threshold levels (see Signal Verification , page 53).
3
Perform a functional check every 6 months (see Functional Check , page 55).
4
Perform the alignment procedure only if the signals are below threshold value
(see
Signal Verification , page 53).
5
Perform zero calibration (see Zero Calibration , page 54) every time the
detector or source is realigned, or the windows are cleaned.
8.2.1 Routine Optical Surface Cleaning
The SafEye system, being an optical device, must be kept as clean as possible.
The optical surfaces involved are the source and detector viewing windows.
To clean the optical window:
1
Disconnect the power to the SafEye Detector and Source.
2
In places where dust or dirt has accumulated on the optical surface, clean the
surface with a small, soft-bristle brush.
