Preventive Maitenance: Testing of UV/IR Flame Detectors Injection Compressor


INJECTION COMPRESOR  FLAME DETECTORS(UV/IR):

REFER TO CAUSE AND EFFECT DIAGRAMS AND SELECT THE CORRECT KEY SWITCH TO BE PLACED IN THE BY-PASS
MODE ON THE CONTROL PANEL AREA MATRIX ON THE FIRE & GAS PANEL PRIOR TO COMMENCING TEST
PLACE THE SELECTED SWITCH IN THE BY-PASS MODE ON THE CONTROL PANEL AREA MATRIX ON THE FIRE & GAS
PANEL AND CONFIRM THE CORRECT BY-PASS LIGHT IS ILLUMINATED
ENSURE THE CORRECT AREA IS BY-PASSED PRIOR TO COMMENCING TEST
ENSURE AKUSTA PANEL IS TURNED TO MANUAL PRIOR TO COMMENCING TEST
NOTE: WRITE THE MODEL AND SERIAL NUMBER OF THE EQUIPMENT ON THE WORK ORDER.

NOTE:
Two Technicians required to perform this task
The technicians will be in radio contact at all times
One technician to be stationed at the Fire and Gas Detection Panel in the Main Control Room.

TASK TO BE PERFORMED Testing of UV/IR Flame Detectors

NOTES:
1.CLEAN ALL INSTRUMENTS AS REQUIRED
2.RAISE A CORRECTIVE WORK ORDER TO REPAIR ANY FAULTS FOUND
TASK TO BE PERFORMED

NOTES:
1.CLEAN ALL INSTRUMENTS AS REQUIRED
2.RAISE A CORRECTIVE WORK ORDER TO REPAIR ANY FAULTS FOUND
Recommended cleaning solution is General Monitors,
Recommended Test Lamp General Monitors

1. Inspect UV/IR Detectors for any physical damage.
2. Ensure device is securely mounted.
3. Inspect electrical cable if visible for any physical damage.
4. Check cable gland and terminal box cover are secure.
5. Ensure tester is fully charged
6. Ensure all Fire & Gas inhibits and isolations are in place prior to commencing test
7. Clean optical surfaces using a soft, lint free cotton swab together with General monitors window solution.
8. Avoid leaving your fingerprints on optical surfaces.
9. Radio check and alert technician at control panel test is about to start
10. Point fire simulator toward IR Detector FROM A DISTANCE OF 15 FEET/4.57 METERS
11. Press the button ensuring the high intensity pulsing beam strikes the detector face squarely.
12. If the system being tested is operating normally the detector will go into WARN condition after a few flashes.
13. Keep the lamp on for the period set by the time delay and the detector will go into alarm.
14. Read the effect on the sensor output signal or through the fire and gas detection system,
15. Confirm by radio to technician at control panel
16. On completion of test ensure all alarms are reset
17. Remove all Fire & Gas inhibits and isolations
18. A 30-second time lapse is required between tests.
19. Sign-off Work Permit and return to operations.
20. Report all findings to supervision and document in CMMS.

Metering BS&W Monitor/Probe Verification/Calibration: AIT TRANSMITTER ANALYZER LACT QUALITY SKID

Ensure that the equipment is isolated and locked off. NOTE: WRITE THE MODEL AND SERIAL NUMBER OF THE EQUIPMENT ON THE WORK ORDER. BS&W Monitoring Instruments Calibration Procedure. BS&W measurement is an important variable and is used to correct the gross volume to net (Dry). The transmitters and computer inputs should be checked at 3 monthly intervals. Any variations outside of specification should be noted and investigated. If a monitor or computer is changed then this should be recorded, and the test performed again. All test equipment should be calibrated at a traceable facility, (e.g. UKAS, NIST or equivalent.) and the calibration validity of one year complied with. Details from the calibration certificate for the test equipment actually used should be recorded on the calibration form. Instrument type and serial numbers where applicable should also be recorded on the calibration form. The BS&W measurement on the skids, is by INVALCO model WCM 7200 / 7300 ...
