14 Troubleshooting

Table 37 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, get a general overview of how the control block/control block segment
works in conjunction with the entire system.
▶ Find out whether or not the control block/control block segment was working as
required in the entire system before the fault occurred.
▶ Try to determine any changes to the entire system in which the control block/
control block segment 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?
▶ Document the work carried out.
▶ If the fault cannot be corrected, please refer to one of the contract
addresses under:
www.boschrexroth.com/addresses or in chapter 10.4 "Spare part".
