Troubleshooting/fault rectification
The following errors could arise during operation. The possible causes for the
errors are listed below, along with how the errors can be remedied.
Errors
Cause(n)
Rectification
Degassing unit is
failing to degas; the
lower pressure does
not drop below
500 mbar (absolute)
Excess air introduction.
The pump unit does not
convey sufficient fluid to
the degassing unit or the
required pressure of 8 to
10 bar is not reached.
Tank or interfaces on the
tank are leaking
Diaphragm is leaking.
Ensure that the
hydraulic system is free
of leaks.
Check the OLF5
bypass flow filtration
unit
Check the
contamination status of
the filter.
The degassing cycle
of the degassing unit
is >3 minutes and/or
there is no pressure
change at the
degassing unit
The float valve is
defective.
Pressure relief valve is
defective or incorrectly
set.
Replace any defective
valves immediately.
Degassing cycle is
considerably
shortened, during
which the pressure in
the degassing unit
alternates back and
forth in one-second
cycles
The float valve is
defective.
Pressure relief valve is
defective.
The pump unit does not
convey sufficient fluid to
the degassing unit.
Check the OLF5
bypass flow filtration
unit
Oil level too low
The unit has a leak.
Ensure that the
hydraulic system is
completely free of
leaks.
The hydraulic system was
not filled with sufficient oil.
Top up the oil – see
page 55.
Too much oil on the
inside/on the
diaphragm
The hydraulic tank is
overfilled.
The diaphragm is leaking.
Exchange the
diaphragm. See page
73 for details.
Further details can be found in the instructions on the components.
