POWER UP AND VERIFICATION
2.4.1
APPLY THE HIGH PRESSURE SUPPLY
This section assumes that the GPC1 system has already been set up, including pressure
interconnection (see Section 2.3.1).
Proceed as follows (numerical references refer to Section 3.1, Figure 6):
Fully back off the
TEST INLET SET regulator
(5).
Close
the
TEST INLET valve
(12).
Open the
TEST OUTLET valve
(15).
Apply the high pressure supply to the
SUPPLY port
(1).
Highly pressurized gas can be extremely hazardous. Before applying pressure to GPC1
and/or the system connected to it, be sure that all pressure vessels and connections are
rated for the pressure levels that will be applied and that all connections have been
properly tightened (see Section 2.4.5). Ensure that the GPC1 TEST INLET SET regulator
is fully backed off and the INLET valve is closed (see Section 2.4.1).
2.4.2
ADJUST INLET PRESSURE
This section assumes that the GPC1 system has already been set up, including pressure
interconnection (see Section 2.3.1).
Be sure the INLET valve is CLOSED before adjusting the TEST INLET SET regulator. If the
INLET valve is open, the supply pressure will be admitted to GPC1 components and
TEST ports.
Turn the
TEST INLET SET regulator
clockwise while observing the
TEST INLET gauge
.
Set the pressure as indicated by the
TEST INLET gauge
to the desired maximum
test pressure. The pressure set by the
TEST INLET SET regulator
is applied to the inlet of
the
INLET valve
.
2.4.3
APPLY PDVV DRIVE PRESSURE
This section assumes that the GPC1 system has already been set up, including pressure
interconnections (see Section 2.3).
Apply drive pressure to the
PDVV DRIVE port
. See Section 2.3.2, Table 2 to determine the
necessary PDVV drive pressure value.
