General safety information
•
Xgard Bright
gas detectors must be installed, operated and maintained in
strict accordance with these instructions, warnings, label information, and
within the limitations stated.
•
Xgard Bright
detectors are designed to detect gases or vapours in air, and
not inert or oxygen deficient atmospheres.
Xgard Bright
oxygen detectors
can measure in oxygen deficient atmospheres. Please note: the exception
is for IR versions of
Xgard Bright
which do not require the presence of
oxygen to function. IRCO2 and IR flammable gas
Xgard Bright
works
perfectly well in inert atmospheres.
• Electrochemical cells used in toxic and oxygen versions of
Xgard Bright
contain small volumes of corrosive electrolyte. Care should be observed
when replacing cells to ensure that the electrolyte does not come into
contact with skin or eyes.
• Maintenance and calibration operations must only be performed by
qualified service personnel.
• Only genuine Crowcon replacement parts must be used, substitute
components may invalidate the certification and warranty of the detector.
•
Xgard Bright
detectors must be protected from extreme vibration, and
direct sunlight in hot environments as this may cause the temperature of
the detector to rise above its specified limits and cause premature failure. A
sunshade is available for
Xgard Bright
.
Note:
If the sinter is subjected to direct water jet the product must be
bump tested with gas to ensure correct operation.
• This equipment must not be used in a Carbon Disulphide atmosphere.
1.3 Storage instructions
Some types of sensor available with
Xgard Bright
have limited life when left
un-powered and/or may be adversely affected by temperature extremes or
environmental contamination. Ideal storage conditions are 20˚C and 60%RH.
Do not expose sensors to contaminants such as silicones, lead compounds and
strong solvents such as isopropanol. It is strongly recommended detectors are
installed and powered within 3 months of purchase.
