Periodic Maintenance
60 SafEye TM Open Path Detection System User Guide
7.2.1 Routine Optical Surface Cleaning
The SafEye system, being an optical device, must be kept as clean as
possible. The optical surfaces concerned are the source and detector
viewing windows.
➢
To clean the optical window:
1
Turn off the power to the SafEye detector and source.
2
Where dust or dirt has accumulated on the optical surface, clean the
surface with a small, soft-bristle brush.
3
Wash the surfaces thoroughly with water and a mild non-abrasive
detergent.
4
Thoroughly rinse the glass surface with clean water, ensuring no
residue is left behind.
5
Dry the glass with a clean, dry, and soft cloth.
6
Enter into the maintenance logbook: date, name of person, and
company who performed the maintenance service.
7
Turn on power to the SafEye detector and source.
8
Perform signal verification (see Signal Verification on page 60).
9
Perform zero calibration (see Zero Calibration on page 56).
10
Perform functional check (see Functional Check of Unit on page 56).
7.2.2 Signal Verification
The Signal Intensity Check determines if there is a misalignment or if the
light source signal is wearing over a period of time. Clean the optical
surfaces prior to performing this check (see
Routine Optical Surface
Cleaning on page 60). This procedure should be performed in clear
weather.
