2-3. CONTROLS AND INDICATORS
Figure 2-1. Controls and Indicators of the Booster Panel Assembly
General. Refer to Figure 2-1. This section describes the various controls and indicators provided for the proper
operation of the equipment. These component designators correspond to those described in Figure 1-3
Schematic Diagram and Figure 1-4 Component Location Diagram.
R1, Low Pressure Regulator. R1 is an adjustable regulator used to control the output pressure from the
nitrogen supply tanks to connector C4 and the nitrogen drive pressure to the booster pump system. The
regulator has a rated outlet working pressure of 0-300 psi. Its output pressure is read on gauge, G2.
R2, High Pressure Regulator. R2 is an adjustable regulator that controls the output pressure to connector C5
by regulating the output pressure available from the booster pump system. The regulator has a 300 to 4500 psi
R3, Shop Air Regulator. R3 is an adjustable regulator that controls the shop air drive pressure for the gas
booster pump. Its output pressure range is 7 to 125 psi and is read on gauge, G2.
