14 Troubleshooting

Table 8 is intended to support troubleshooting. This table is not exhaustive.
Issues may occur in practice that are not listed here.
Only authorized personnel may perform troubleshooting inside a safety area
designated by the machine manufacturer.
14�1 How to proceed for troubleshooting
▶ Use a systematic and targeted approach, even when pressed for time. Random
and imprudent removal and changing of settings could result in the inability
to ascertain the original error cause.
▶ First, make yourself familiar with the function of the control block in
conjunction with the entire system.
▶ Find out whether or not the control block rendered the required function in the
entire system before the fault occurred.
▶ Collect the changes to the entire system in which the control block is installed:
– Have there been any changes to the application conditions or operating range
of the product?
– Has maintenance work recently been carried out? Is there an inspection
or maintenance log?
– Have any changes (e.g. upgrades) or repairs been made to the overall system
(machine, electrics, control) or to the product? If yes: What changes?
– Has the hydraulic fluid been changed?
– Has the product or machine been used as intended?
– How does the malfunction appear?
▶ Try to get a clear idea of the cause of the fault. Directly ask the (machine)
operator.
▶ Document the work carried out.
▶ If the fault cannot be corrected, please refer to one of the contract addresses
at: https://addresses.boschrexroth.com or in chapter 10.5 "Spare part".
