[EN] English - K0463 Revision A
Refer to the figures on the front cover (A2, B1).
1. Optional accessory: Pressure connection for a pressure relief valve
(PRV); see table A1.2 (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-IS module.
PV 621-IS/PV 622-IS models: Seal the pressure connection with a
blanking plug (Part: IO620-BLANK) or a PM 620-IS module.
PV 623-IS models only: The pressure connection seals itself.
4. Pneumatic pressure release valve (PV 621-IS/PV 622-IS models) or
hydraulic pressure release valve (PV 623-IS models) to release
pressure in the system.
On PV 623-IS models, it also gives access to the hydraulic fluid
reservoir; see figure A4 (front cover).
5. PV 622-IS 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-IS calibrator with electrical
connections and a mechanism to hold it in position.
7.
Push-button mechanism to release the DPI 620G-IS calibrator.
8. PV 621-IS models only: Pneumatic volume adjuster.
9. PV 622-IS/PV 623-IS models only: Volume adjuster wheel with fold-in
handle.
10. PV 623-IS 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 621-IS/PV 622-IS models only: Pressure/vacuum selector to set
the pump operation: pressure (+), vacuum (-).
12. PV 621-IS/PV 622-IS models only: Pump mechanism.
