4.2 Control Specifications for the Pump Regulator Module
External Pressure Requirements:
Source Requirements Fast Mode: 10% over range of highest pressure
transducer.
Slow Mode: None.
Note: The difference between the source pressure and
the minimum controlled pressure must be less than
30 psi. Performance can be enhanced with a well-
regulated source pressure.
Exhaust Requirements Fast Mode: A vacuum source is required for sub-at-
mospheric pressure control.
Slow Mode: None
Stability of Controlled Pressure Fast and Slow Mode: 0.003% of span of active range,
typically better than 0.001% of span 10 seconds after
displaying stable flag.
Available Sensor Range Fast Mode: Absolute: 0 to 5 psia to 0 to 30 psia
Gauge: 0 to .36 psig to 0 to 15 psig
Bi-directional: -.18 to +.18 psi to -atm to 15 psig
Slow Mode: Absolute: 0 to 5 psia to 0 to 30 psia
Gauge: 0 to .36 psig to 0 to 15 psig.
Minimum Controlled Pressure Fast and Slow Mode: 0.05% FS or .05 psi over ex-
haust pressure, whichever is greater. The minimum
control point on absolute ranges is .5 psia.
Pressure Control Rates Fast Mode: Fast control mode uses the roughing
valves.
Slow Mode: Slow mode uses only the pump.
