401812 PressAlrmEnable

0 = No alarms.

1 = High Pressure only.

2 = Low Pressure only.

3 = High and Low Pressure.

401813 Press_Mon Indicates to the system that a transducer is present to read.

1 = Enable pressure transducer reads.

0 = Disable pressure transducer reads.

401814 SleepSetpt Setpoint for Sleep Mode x 10 (GPM or LPM)

401815 RunSetpt Setpoint for Run Mode x 10 (GPM or LPM)

401816 SleepEnable

1 = Sleep Mode is on. The Sleep Setpoint is used as the target flow rate.

0 = Sleep off. The Run Setpoint is used as the target flow rate.

Sleep can also be enable by the external AutoSleep input pin. Sleep

Mode is enabled when either control is active.

401817 PressSetPt Pressure Mode setpoint x 10. This is the target pressure for Pressure

Control Mode.

401818 Cntrl_Mode 0 = Flow Control. Maintains a constant flow rate. Flow rate is either Sleep

or Run Setpoint, depending on 1816_SleepEnable input.

1 = Pressure Control. Maintains a constant pressure defined by

401817_PressSetPt.

401820 AutoDecrement 1 = Enabled; automatically minimizes the flow rate in pressure mode,

allowing the BPR to close. See Auto Decrement, page 27.

401821 RunStop 1 = Run

0 = Stop

Power up or Reset will set RunStop to 1.

401822 GaugePresH High Gauge Pressure entered during calibration, PSI only

401823 GaugePresL Low Gauge Pressure entered during calibration, PSI only

401824 ADmAHigh High pressure CAL, Transducer current xx.x mA.

401825 ADmAHigh Low pressure CAL, Transducer current xx.x mA.

401828 AutoXducerFail Determines how the ACS responds to a pressure transducer failure.

1 = Run at constant flow rate determined by Run or Sleep setpoint.

0 = Stop the pump.
