4. Troubleshooting measures .
If faults cannot be repaired, the system must be put out of operation
immediately and this information is to be given to the manufacturer.
Repairs must only be carried out by the manufacturer. Interventions and
changes on the appliance are not allowed.
In case of faults caused by defects of the hydraulic equipment the operators must inform their
superiors immediately and call in the qualified and authorised technical staff for maintenance.
Table: Fault description and measures
.
Type of fault Measures
I. Unable to build up pressure during pre-
pressure generation
Close low-pressure shut-off valve
correctly
Attention: Do not tighten the shut-off
valve more than finger tight. Otherwise
the valve seat could be damaged.
Check whether there is enough operating
fluid in the tank.
II. Unable to build up further pressure at high-
pressure generation with the spindle pump
Close high-pressure shut-off valve
correctly
Please note: In case of an opened, or not
properly closed high-pressure shut-off
valve, the safety overflow valve is not
activated until approximately 100 bar are
reached, and the oil will flow back into the
tank. Therefore, no pressure > 100 bar
can be built up.
III. Unable to build up pressure / oil discharge at
the test connections
Tighten the test specimen and the
reference instrument with the connecting
adapter and knurled nut (see section
3.1.2)
In case of wear or damage to the sealing
cone, proceed as described in section 5.1.
IV. Unable to build up pressure, or range cannot
be reached
After the clamping of the test specimen
and the reference instrument, air may be
trapped in the system.
Please note: The system should be
vented before beginning with calibration.
For this purpose, proceed according to
section 3.1.3.
Afterwards, build the pressure back up.
