10 Maintenance
Safety instructions
Corrective maintenance work may only be performed by
trained personnel.
• Before removing the device, depressurize it along with any
adjacent lines or vessels.
• Check whether hazardous materials have been used as
measuring medium before opening the device. Residual
amounts of hazardous material may still be present in the
device and could escape when it is opened.
Within the scope of operator responsibility, check the
following as part of a regular inspection:
• pressure-carrying walls / pressure equipment liner
• the measurement-related function
• the leak tightness
• the wear (corrosion)
WARNING
WARNING
Risk of burns due to hot measuring media
depending on the measuring medium temperature!
• Before starting work on the device, make sure that it
has cooled sufficiently.
Damage to components!
The electronic components of the printed circuit board
can be damaged by static electricity (observe ESD
guidelines).
• Make sure that the static electricity in your body is
discharged before touching electronic components.
CAUT ION
NOTICE
Risk of injury due to live parts!
When the housing is open, contact protection is not
provided and EMC protection is limited.
• Before opening the housing, switch off the power
supply.
Loss of Ex-approval!
Loss of Ex approval due to replacement of components
in devices for use in potentially explosive atmospheres.
• Devices for use in potentially explosive atmospheres
may be serviced and repaired by qualified ABB
personnel only.
• For measuring devices for potentially explosive
atmospheres, observe the relevant operator
guidelines.
