6. Maintenance and troubleshooting
6.1 Error conditions, troubleshooting
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.
In case of equipment faults, remove the equipment. The inner
parts cannot be maintained by the customer. In this case send the
equipment to the manufacturer for inspection.
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
functions.
Inspection: Defines an activity with the purpose to check a product
carefully, aiming at a reliable statement on the condition of the
product. The inspection is carried out without dismantling, or, if
necessary, with partial dismantling, and supplemented by other
measures, e.g. measurements.
Visual inspection: Optical inspection of product aims at the recognition
of visible defects like missing bolts without using auxiliary equipment
and tools.
Close inspection: Defines an inspection which encompasses those
aspects covered by a visual inspection and, in addition, identifies those
defects, such as loose bolts, which will be apparent only by the use of
access equipment, for example steps, where necessary, and tools.
