normal condition. Use the applicable protection and
obey all safety precautions.
• Do not use the instrument in locations with explosive
gas, vapour or dust. There is a risk of an explosion.
•It is dangerous to attach an external sour ce of pressure
to a PV 62x series pressure st ation. Use only the
internal mechanisms to set and control the pressure in
the pressure station.
• Some liquid and gas mixtures are dangerous. This
includes mixtures that occur be cause of con t amination.
Make sure that the equipment is safe to use with the
necessary media.

2.3.1 Procedure (to attach)
2.3.2 Procedure
(to remove)
To remove a device, release the pressure first (Section 2.2).
You can then do steps 4, 3, and 1 in Section 2.3.1 but do the
operations in the opposite direction.
2.4 Attach/Adjust a
PRV
WARNING: Pre ssurized gases and fluids are dangerous.
Before you attach or disconnect pressure equipment,
safely release all the pressure.
Optional accessory; see Section 1.5 (Access ories). Use a
pneumatic pressure relief valve (PRV) to set a limit to the
pressure you can apply to the pressure device s attached to the
pressure station. The PR V i s set at the fact ory to operat e at the
maximum pressure specified on the label.
If the pressure in the instrument is more t han the relief pressure
set for the PRV, the PRV controls a slow release of the
unwanted pressure. The correct PRV helps prevent
overpressure and damage to the attached devices.
To adjust the PRV, see Section 2.4.2.
