12.5 Recycling
Due to the high metal share, hydraulic products can mostly be recycled. In order to
achieve an ideal metal recovery, disassembly into individual assemblies is required.
13 Extension and modification
Do not retrofit the safety valve.
14 Troubleshooting
14.1 How to proceed for troubleshooting
▶
Always work systematically and purposefully, even when under time pressure.
Random and imprudent disassembly and readjustment of settings can, in the
worst-case scenario, result in the inability to determine the original cause of error.
▶
First, get a general idea of how the safety valve works in conjunction with the
overall system.
▶
Try to find out whether the safety valve has worked properly in conjunction with
the overall system before the error occurred first.
▶
Try to determine any changes of the overall system in which the safety valve is
integrated:
– Were there any changes to the safety valve's application conditions or area of
application?
– Have changes (refittings) or repair works been carried out at the overall system
(machine/system, electrical systems, control) or at the safety valve? If so: What
were they?
– Was the safety valve or machine used as intended?
– How did the fault become apparent?
▶
Try to get a clear idea of the cause of the error. If necessary, ask the actual
(machine) operator.
