Ultraviolet radiation sensing tubes have a life
expectancy of 40,000 hours of continuous use within
the flame detector's specified ambient temperature
and voltage ratings. Wearout of an ultraviolet
radiation sensing tube results in failure of the UV
sensor to properly discriminate between flame
conditions.
The C7027A, C7035A and C7044A Flame Detectors
should only be used on burners that cycle on/off
periodically or, in the absence of cycling, are
periodically checked for proper operation.
Recommended industry standards for the frequency
of sensor checks, either through cycling (employing
safe-start check methods) or periodic maintenance,
vary between once every ten seconds and once
every week, depending on the standard used and
the application needs.
Consult the equipment manufacturer or the
governing standard for recommendations about
frequency of checks.
Controls incorporating safe-start checks, and
sensors and controls employing constant check
means are available from Honeywell. See your
Honeywell representative for specific information.
