6. Maintenance and troubleshooting
6.1 Error conditions, troubleshooting
See chapter “5.6.1 Layer Setting Service (LSS)” on page 31.
6.2 Maintenance
The required inspections need to be performed by qualified personnel
according to IEC 60079-17 / TRBS 1203. These inspections should
include at least a visual inspection of the housing, associated electrical
equipment entrance points, retention hardware and equipment
grounding. Inside the Ex-atmosphere the equipment has to be cleaned
regularly. The user determines the intervals for checking according
to the environmental conditions present at the place of operation.
After maintenance and repair, all protective devices removed for this
purpose must be refitted.
NOTICE
Perform maintenance work that requires a dismantling of the
system only in an Ex-free atmosphere. If this is not possible take
protective measures in compliance with local regulations.
Maintenance: Defines a combination of any actions carried out to
retain an item in, or restore it to, conditions in which it is able to meet
the requirements of the relevant specification and perform its required

aspects covered by a close inspection and, in addition, identifies those
defects, such as loose terminations, which will only be apparent by
opening the enclosure, and / or using, where necessary, tools and test
equipment.
