The pressure relief valve (PRV) can be set at pressures from 30 to 700
bar.
Do not exceed 700 bar as this can .damage the internal seals of
the PRV and the PV411
If the system pressure exceeds the set pressure, the PRV opens and

9.3.2 Hydraulic Operation of the PV411
As a hydraulic pump, selector valve ➆ vents the system to the
reservoir, between selections of pressure and vacuum (using a priming
process). The volume adjuster ➂generates the required system
pressure. To complete the hydraulic circuit, the fluid reservoir (see
drawing key 2) is screwed into the inlet port ➀ (marked RESERVOIR)
on top of the hand-pump. A pressure relief valve ➇ can be adjusted to
set the pressure between 30 and 70 bar. Operating the scissor-action
handles ➄ provides the pumping stroke for generating pressure. A
volume adjuster ➂ allows small adjustments of the system pressure.
The fluid-reservoir body (see drawing key 2) is transparent acrylic to
provide a clear view of the contents. The reservoir can be removed
from the pump without the need to empty the fluid (a self-sealing
connection prevents leakage). The spring-loaded reservoir cover ➁
seals under atmospheric pressure conditions but, in the event of
inadvertent pressurization, it will vent excess internal pressure
harmlessly. Ensure that the O-ring ➂ is fitted to the inlet pot to prevent
leakage. Screw the reservoir clockwise into the inlet port marked
RESERVOIR.

9.4 PV411 FAULT INVESTIGATION
If the system pressure reduces, check the following:
Refer to the orientation drawing PV411 drawing key 1 to locate the
controls.
1. Check that the selector valve ➆ is in the correct position and
properly tightened.
2. Allow sufficient time after generating pressure for the temperature
to stabilize. The larger the system volume, the longer the time for
thermal stability.
3. Check for leaks between the pump and the equipment under test
and the adaptors, flexible pipe and connections. Tighten any
loose joints and replace any seals that are worn or damaged.
4. In hydraulic mode, if the volume adjuster can be wound fully in, but
maximum pressure cannot be achieved, there is probably air
trapped in the system. Re-prime and repeat.
5. Check the Pressure-Relief Valve ➇ pressure setting.
If, for any reason, a fault occurs within the pump, it is recommended
that the equipment be returned to Scan-Sense AS.
