SafEye TM Xenon 700S SIL Gas Detector
48 Periodic Maintenance
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, proceed as follows:
1 Turn off 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.
3 The surfaces must then be washed 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 soft cloth.
6 Enter in 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, page 43).
9 Perform zero calibration (see Zero Calibration, page 44).
10 Perform functional check (see Functional Check of Unit, page 45)
7.2.2 Signal Verification
The signal verification check determines the proper operation of the open
path. It checks the alignment and cleanliness of the window or any problem
in Source or Detector. Use the PC Host software to measure the signal
verification.
Refer to Manual TM 799060 or use I.S handheld unit. Refer to Manual
TM 777070 for non I.S Mini laptop Unit.
7.2.3 Function Check of Unit
The SafEye Xenon system has been calibrated at the factory per the user’s
specific gas or vapor detection requirements. This procedure validates the
functional operation. The functional check must be done periodically. Refer
to Functional Check of Unit, page 45 for instructions.
Caution: Automatic activation or any external device that should not be
activated during the calibration check should be disconnected.
