9. Maintenance and repair
Careful and regular maintenance is required in order to detect
and remedy possible faults in time. The operator must always
determine the specific intervals according to the operating
conditions, review them regularly, and adjust them where
necessary. If necessary, copy the table for regular maintenance
activities.
9.1 Maintenance for flow limiters
Careful and regular maintenance is required in order to detect
and remedy possibly malfunctions in time. The specific intervals
must always be determined by the operator according to the
operating conditions and the local conditions and regularly
reviewed and adapted where necessary.
In particular with maintenance and repair work, the following
safety measures must implemented at a minimum:
•
Prevent access by unauthorized persons
•
Mark and secure the work area
•
Depressurize flow limiters
•
Cover any live parts in the surrounding area
•
Ensure that no explosive atmosphere is present

If present, electrical connection of the 3/2 changeover valve 24-1254-3437 is executed
correctly
Protective earthing system (PE) fully present, properly connected, and electrically continuous
The performance characteristics for the aforementioned connections match the specifications
in "Technical data"
All components such as lubrication piping are correctly mounted
No apparent damage, contamination, or corrosion
Any dismantled protective or monitoring equipment is fully reinstalled and functional
--
No unusual noises, vibrations, moisture accumulation, odors present
No undesired discharge of lubricant at connections
Lubricant is fed without bubbles
The bearings and friction points requiring lubrication receive the planned lubricant volume. If
this is not the case, then the plug-in nozzle is to be cleaned/replaced - see Chapter 9.3
(customer specification of scheduling)
No accumulated dust present, clean as needed
Varnished surfaces: Varnish must be present in its entirety, replace the varnish as needed
NOTE
1)
The maintenance intervals depend greatly on the degree of cleanliness and contamination of the lubricant used, they are therefore
only reference values. The determination of the intervals is the responsibility of the operator, based on existing conditions.
