MAINTENANCE FOR AREARAE STEEL

7-10

7.6 Taking Care of the Lamp

During the course of regular operation, the UV lamp becomes
contaminated. Therefore, the lamp requires periodic cleaning.
The “Lamp” error is an indication of a problem with the lamp
current. A dirty or contaminated sensor often causes high
readings of the VOC sensor. A weak or inoperative lamp often
causes low readings or no response to test gas. If the UV lamp
is on while the error message persists, then it is necessary to
adjust the lamp threshold. Refer to Chapter 8 for details of
adjusting the threshold level for the UV lamp.

CAUTION!

Never touch the window surface with fingers or anything that
may leave a film. Water degrades window surfaces, especially
the 11.7 eV lamp.
