[. . . ] Operation and Maintenance Manual GPC1-10000/GPC1-16000TM Gas Pressure Controller © 2007 DH Instruments, a Fluke Company GPC1-10000 / GPC1-16000TM OPERATION AND MAINTENANCE MANUAL High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and gases can be released unexpectedly and with extreme force. High pressure systems should be assembled and operated only by personnel who have been instructed in proper safety practices. © 2007 DH Instruments, a Fluke Company All rights reserved.

[. . . ] At high pressure, the and push button valves increase pressure much more quickly than at low pressure. Observe pressure evolution carefully when operating these valves (see Section 3. 2. 3). Drain/purge the GPC1 sump regularly to remove any contaminants that may have entered the system from the supply gas or devices connected to GPC1 (see Section 3. 2. 5). Put the PDVV plunger in the START position when starting a calibration or test sequence (see Section 3. 2. 3). Systems and DUTs connected to GPC1 should be emptied of liquids before they are pressurized (see Section 3. 2. 5, 4. 2). · · · · 2. 5 STORAGE AND SHIPPING When leaving GPC1 at rest but still setup for operation: Fully close the INLET valve. Release pneumatic supply pressure by fully backing off the TEST INLET SET regulator. To prepare GPC1 for long term storage or shipping: Disconnect all pneumatic pressure connections and plug the DH500 connections using DH500 plugs or dummy plugs held by gland nuts. If it is necessary to use alternate materials, use caution and ensure that: a) the front panel controls and indicators are protected; and, b) the tubing and components exposed through GPC1's open bottom are protected. GPC1 must ride on its four (4) feet - NOT on its internal components. © 2007 DH Instruments, a Fluke Company Page 14 2. 5BINSTALLATION 2. 6 SPECIAL CONSIDERATIONS FOR HYDROCARBON FREE OPERATION A special "hydrocarbon free" version of GPC1 (P/N 401801 or P/N 402201) is available. This part number is delivered free of known sources of hydrocarbon in the GPC1 high pressure gas circuit. Of course, GPC1 will remain hydrocarbon free only so long as hydrocarbons are not introduced from an external source. To maintain a hydrocarbon free GPC1, only connect devices to it that are known to be hydrocarbon free. If using a gas booster to supply the high pressure, the gas booster must be a hydrocarbon free version. If using a PG7202 piston gauge, the PG7202 must be a hydrocarbon free version and used with Krytox® lubricated piston-cylinder modules.

OPERATION 3. 3. 1 OPERATION OPERATING PRINCIPLE Numerical references in this section refer to Section 3. 1, Figure 6. GPC1 is a self-contained system designed to set and adjust gas pressure into static pressure test and calibration systems. GPC1-16000 operates from atmosphere (zero gauge) to 110 MPa (16 000 psi). GPC1 combines the capability to execute large pressure changes very quickly with very fine pressure adjustment. These are rough pressure control using the TEST INLET valve (12) and TEST OUTLET valve (15) and fine pressure control using the PDVV (+) (13) and (-) valves (14). The first means of generating and adjusting pressure uses the external gas pressure supply (1) with the TEST INLET SET regulator (5), TEST INLET valve (12) and TEST OUTLET valve (15). This combination is used for filling the system under test, making large pressure changes and for rough pressure control. [. . . ] PDVV is at minimum end of stroke position. PDVV will not increase pressure. PDVV will not decrease pressure. Opening INLET valve increase pressure. does not TEST INLET SET regulator is set too low and/or external pressure supply to low.
