12.5 Recycling
Due to the high metal content, hydraulic products can mostly be recycled. In order to
achieve an ideal metal recovery, disassembly into individual assemblies is required.
The metals contained in electric and electronic assemblies can be recovered by
means of special separation procedures as well.
13 Extension and modification
WARNING
Explosion hazard caused by unauthorized modification!
Every non-permitted modification will void the explosion protection.
▶ Modifications exceeding the extent described in these operating instructions are
not permitted.
▶ The pilot control valve and the twin throttle check valve (for versionS andS2)
must not be exchanged or replaced by another one.
▶ Additional components like e.g.throttles, preload or pressure reducing valves
must not be installed into the valve.
▶ Such changes may only be carried out by persons authorized by the
manufacturer.
14 Troubleshooting
14.1 How to proceed for troubleshooting
▶ Always work systematically and purposefully, even when under time pressure.
Inthe worst case, random, thoughtless disassembly and changing settings might
result in the inability to identify the original cause of error.
▶ First, get an overview of the functions of the valve in conjunction with the
overallsystem.
▶ Try to find out whether the valve has worked properly in conjunction with the
overall system before the error occurred.
▶ Try to determine any changes to the overall system in which the valve is
integrated:
–Were there any changes to the application conditions or area of application of
the valve?
–Have changes (e.g.refitting) or repair work been carried out at the overall
system (machine/system, electrical systems, control) or at the valve?
Ifso:Whatwere they?
–Was the valve and/or the machine used as intended?
–How did the fault become apparent?
