THIS SAFETY DATA SHEET APPLIES TO WC3000 INSITU OXYGEN ANALYZER

(PROBE),TYPE No. 1U05680. THIS OXYGEN ANALYZER IS CERTIFIED EExd lIB 370 (T1):

ISSeP CERTIFICATE No. 93C.103.1067.

THIS PIECE OF EQUIPMENT HAS BEEN DESIGNED AND MANUFACTURED TO OPERATE

SAFELY IN CERTAIN TYPES OF POTENTIALLY EXPLOSIVE ATMOSPHERES. IT IS ESSENTIAL

THAT THE EQUIPMENT IS NOT TAMPERED WITH OR DAMAGED IN ANY WAY WHICH

MIGHT LEAD TO A REDUCTION IN IT'S ABILITY TO OPERATE SAFELY IN SUCH POTENTIALLY

EXPLOSIVE ATMOSPHERES. FOR YOUR OWN SAFETY AND THE SAFETY OF OTHERS

PLEASE BRING ANY DAMAGE TO THE ATTENTION OF THE RESPONSIBLE AUTHORITY.

THIS PIECE OF EQUIPMENT HAS BEEN DESIGNED AND MANUFACTURED IN

ACCORDANCE WITH EUROPEAN STANDARDS EN50014 & EN50018. INSTALLATION

MAINTENANCE AND REPAIR MUST BE IN ACCORDANCE WITH THE OFFICIAL “CODES

OF PRACTICE ON THE INSTALLATION AND MAINTENANCE OF ELECTRICAL APPARATUS

IN POTENTIALLY EXPLOSIVE ATMOSPHERES’' FOR THE COUNTRY OF INSTALLATION

(EXAMPLE: BS5345 IN GREAT BRITAIN). ONLY APPROPRIATELY TRAINED PERSONNEL

ARE AUTHORIZED TO PERFORM ANY WORK ON THIS EQUIPMENT. SUCH PERSONNEL IN

ADDITION TO OPERATING TO THE ABOVE MENTIONED SAFETY STANDARDS, SHOULD TAKE

NOTE OF THE FOLLOWING SAFETY ISSUES.

NOTE: THROUGHOUT THIS DATA SHEET, CONTINUOUS REFERENCE WILL BE MADE TO

FIGURE 1.

(1)

THIS PIECE OF APPARATUS IS NOT ITSELF FITTED

WITH A MEANS OF ELECTRICAL ISOLATION. CONSULT YOUR LOCAL CODES OF PRACTICE

ON THE INSTALLATION AND MAINTENANCE OF ELECTRICAL APPARATUS IN POTENTIALLY

EXPLOSIVE ATMOSPHERES (BS5345 IN BRITAIN) FOR INSTRUCTION ON THE ISOLATION OF

ELECTRICAL SUPPLY TO THE APPARATUS. FURTHER MORE THERE MUST BE “EFFECTIVE

MEASURES TO PREVENT THE RESTORATION OF SUPPLY TO THE APPARATUS WHILE THE

RISK OF EXPOSING UNPROTECTED LIVE CONDUCTORS TO AN EXPLOSIVE ATMOSPHERE

CONTINUES”:BS5345 PART 1 1989 SECTION 18.

“WHERE, FOR PURPOSES OF

ELECTRICAL TESTING, IT IS ESSENTIAL TO RESTORE THE SUPPLY BEFORE THE APPARATUS

IS REASSEMBLED, THEN THIS WORK SHOULD BE UNDER A CONTROLLED PROCEDURE

AND THE SPECIFIC LOCATION ASSESSED TO ENSURE THAT POTENTIALLY FLAMMABLE

GAS OR VAPOUR IS ABSENT”:BS5345 PART 1 1989 SECTION 23.

DO NOT REMOVE THE JUNCTION BOX COVER

(ITEM 2) WHILE THE APPARATUS IS ENERGIZED. DO NOT REMOVE THE JUNCTION BOX

COVER WHEN A POTENTIALLY EXPLOSIVE ATMOSPHERE IS PRESENT. REMEMBER (ALTHOUGH

THE UNIT HAS BEEN POWERED DOWN AND THE PROBE HEATER HAS BEEN ALLOWED TO

COOL DOWN), THE TEMPERATURE ON THE INTERIOR OF THE PROBE TUBE (ITEM 1) WILL BE

SIMILAR TO THE TEMPERATURE OF THE EXHAUST GAS. IF THERE IS A POTENTIALLY

EXPLOSIVE ATMOSPHERE IN THE REGION OF THE JUNCTION BOX (ITEM 3), THIS GAS WILL,

ON THE REMOVAL OF THE JUNCTION BOX COVER BE EXPOSED TO THE HOT SURFACE OF

THE TUBE INTERIOR (ITEM 1).

(2) THE JOINT BETWEEN THE JUNCTION BOX (ITEM 3) AND THE

JUNCTION BOX LID (ITEM 2) IS A THREADED JOINT. SO ALSO IS THE JOINT BETWEEN

THE PROBE END FLANGE (ITEM 4) AND THE FLAME ARRESTOR HUB (ITEM 5). BOTH

THESE JOINTS ARE SECURED BY SET SCREWS (ITEMS 6 & 7). BEFORE REMOVING

THE JUNCTION BOX COVER (ITEM 2) OR THE FLAME ARRESTOR HUB (ITEM 5), FULLY

REMOVE THE SET-SCREWS (ITEMS6&7)FROM THEIR TAPPED HOLES. FAILURE TO

DO THIS COULD RESULT IN DAMAGE TO THE THREADS OF THE JUNCTION BOX (ITEM 3)

AND THE PROBE END FLANGE (ITEM 4) BY THE SETSCREWS BEING DRAWN OVER

THE THREADS. REMEMBER WHEN REFITTING THE JUNCTION BOX LID AND THE FLAME

ARRESTOR HUB TO LOCK IN PLACE WITH THE SETSCREWS.

THE MATERIAL OF THE JUNCTION BOX AND THE JUNCTION BOX LID IS ALUMINUM

ALLOY. SPECIAL CARE SHOULD BE TAKEN TO AVOID DAMAGE TO THE THREADS.

NOTE THAT ROSEMOUNT SUPPLIES ALLEN KEYS FOR REMOVAL & REPLACEMENT OF THE

SETSCREWS.
