5.7.2 Procedure
1. If applicable, release the pressure (Section
5.2) and remove the equipment under test
2).
Note:
If connected, remove the DPI
620G / DPI
620G
-
IS calibrator.
2. Remove the pressure release valve.
3. Turn the volume adjuster wheel fully clockwise. This removes the fluid out of the pressure
mechanism.
4. Put a container below the pressure station. Tilt the pressure station until all the fluid has
come out. Fluid comes out of the test port and the pressure release valve connection.
Note:
To discard the hydraulic fluid, obey all the local health and safety procedures.
5. To remove contaminated hydraulic fluid, refill the system and repeat steps
3 and
4.
Note:
To prevent contamination use only one type of hydraulic fluid in the pressure station.
6. Pressure Relief Valve (PRV)
6.1 Introduction
Use a pressure relief valve (PRV) to limit the pressure you can apply to the equipment under test.
The PRV is factory set to operate at the maximum pressure specified on the label (on the plastic
cap).
If the pressure in the pressure station is more than the PRV relief pressure, the PRV controls a
slow release of the unwanted pressure. The correct PRV helps prevent overpressure and
damage to the equipment under test. To adjust the PRV, see Section
6.3.
WARNING
Pressurized gases and fluids are dangerous. Before you connect
or disconnect pressure equipment, safely release all pressure.
CAUTION
To prevent damage to the pressure station, do not let dirt get into
the pressure mechanism. Before fitting the pressure relief valve (PRV), make
sure it is clean.
