Troubleshooting; How To Proceed For Troubleshooting - Bosch Rexroth A10VSNO Instruction Manual

14 Troubleshooting

Table 14 is intended to help you with 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

▶ Preferably perform the troubleshooting with reduced operating data (e.g., slowly
swinging in or out and slow pressure increase).
▶ Use a systematic and targeted approach, even when pressed for time. Random
and indiscriminate removal and changing of settings could result in the inability to
determine the original cause of the fault.
▶ First get a general idea of how your product works in conjunction with the entire
system.
▶ Try to find out whether or not the product was working properly in conjunction
with the entire system before the fault occurred.
▶ Try to determine any changes to the entire system in which the product is
installed:
– Were there any changes to the product's application conditions or operating
range?
– 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/system, electronics, control) or to the product? If yes, which?
– 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 you cannot rectify the fault, get in touch with one of the contact addresses
