Troubleshooting 57/64
RE 50129-B/02.19, Accumulator shut-off block type ABZSS, 0532VAW,
Bosch Rexroth AG
Use Table 9 for troubleshooting. The table does not claim to be complete.
In practice, there may be problems that are not included here.
14.1 How to proceed for troubleshooting
▶
Always work systematically and purposefully, even when under time pressure.
Random, thoughtless disassembly and changing of settings might result in the
inability to restore the original error cause.
▶
First, get a general idea of the function of the accumulator shut-off block works in
conjunction with the overall machinery.
▶
Try to find out whether the accumulator shut-off block has worked properly in
conjunction with the overall machinery before the error occurred first.
▶
Try to determine any changes of the overall machinery/system in which the
accumulator shut-off block is integrated:
– Were there any changes to the application conditions or area of application of
the accumulator shut-off block?
– Has any maintenance work been performed recently? Is there an inspection or
maintenance record?
– Have modifications (e.g. refitting) or repair been performed at the overall
machinery/system (machine/system, electrical system, control system) or at the
accumulator shut-off block? If yes: What were they?
– Was the hydraulic fluid changed?
– Was the accumulator shut-off block or the machine/system used as intended?
– How did the fault become apparent?
▶
Try to get a clear idea of the cause of error. If necessary, ask the actual (machine)
operator.
▶
Document all work done.
▶
If the error could not be corrected, please refer to one of the contact addresses
specified in the list of addresses in chapter 16.1.
