[EN] English - K0458 Revision B
1. Optional accessory: Pressure connection for a pressure relief valve
(PRV); see table A1.3 (front cover). A blanking plug is standard.
2.
Test port: Pressure connection (G1/8 or 1/8NPT) to attach the device
under test; see figure A3 (front cover).
3. Pressure and electrical connections for a PM 620 module.
PV 621G/PV 622G models: Seal the pressure connection with a
blanking plug (Part: IO620-BLANK) or a PM 620 module.
PV 623G models only: The pressure connection seals itself.
4. Pneumatic pressure release valve (PV 621G/PV 622G models) or
hydraulic pressure release valve (PV 623G models) to release
pressure in the system.
On PV 623G models, it also gives access to the hydraulic fluid
reservoir; see figure A4 (front cover).
5. PV 622G models only: Pneumatic refill valve. Close it to seal off the
device pressure and refill the pressure mechanism (refer to "Quick
Reference", S2).
6. Moulded compartment for the DPI 620G calibrator with electrical
connections and a mechanism to hold it in position.
7.
Push-button mechanism to release the DPI 620G calibrator.
8. PV 621G models only: Pneumatic volume adjuster
9. PV 622G/PV 623G models only: Volume adjuster wheel with fold-in
handle.
10. PV 623G models only: Hydraulic refill valve. Close it to seal off the
device pressure and refill the pressure mechanism with fluid (refer to
"Quick Reference", S3).
11. PV 621G/PV 622G models only: Pressure/vacuum selector to set the
pump operation: pressure (+), vacuum (-).
12. PV 621G/PV 622G models only: Pump mechanism
Pressure module (PM 620) with a pressure connection, reference port
(a) and a label. The label includes:
Pressure limit. Example: 20 bar g (g: gauge; a: absolute); serial
number (S/N); manufacturer: name, address, website
