- Check control cabinet and cable assemblies (visual inspection)
Carrying out the maintenance activities described below requires
special knowledge. For this reason, these maintenance activities
must only be carried out by staff that has received adequate training
by the machine manufacturer!
Orientation
To avoid problems and prevent any resulting system failures, simplified control
cabinet checks must be carried out at regular intervals on the cabinet and
associated components. This include a visual inspection of the wire harnesses of
the individual modules and the grounding cable. Additional built-in air conditioning
units (option) ensure a constant temperature in the control cabinet. These air
conditioners cannot work efficiently if filters are dirty or doors are not tight.
Use only the original filters according to the spare or wear parts list!
Filters are hazardous waste and must be disposed of in accordance
with environmental guidelines and regulations of the country of
operation.
When working in or on the control cabinet, switch off the machine and
secure it against power on.
Requirement
Even with the machine powered off, some devices or components in
the control cabinet are still energized.
Observe the specific electrical diagrams for this machine.
Procedure
1. Switch off the machine.
2. Have the electrical diagrams for the corresponding machine ready.
3. Replace all filters on the control cabinet and cabinet components.
4. Check that the cabinet doors can be properly closed. If the cabinet doors can
not be closed properly, determine the cause and eliminate it. Possible causes
could be faulty seals, hinges, or even a damaged cabinet door.
5. Check all cabinet seals. They should be free of oil and condensation.
6. Clean the control cabinet. Use a suitable vacuum cleaner for this purpose.
7. Check the cabinet lighting (optional).
