IMPORTANT
During commissioning, maintenance or repair, always use the check lists in chap-
ter 2.11 and 2.12, in order to document the accuracy and completeness of your
work.
Visual Inspection
Regularly perform a visual inspection at least once every three years. To do this,
use the plan for the visual inspection from chapter 2.11. Initiate immediate appro-
priate measures if you discover damage during visual inspection. If necessary, im-
mediately disconnect the detector from the power supply.
When determining the intervals for the visual inspection, the following conditions
are to be considered:
•
ambient conditions (temperature, humidity, corrosive atmosphere, shock
and vibration).
•
operating conditions (utilization, incorrect operation).
•
major changes in the whole system (e.g. changes in the classification of ex-
plosion protection zones).
