PPC2 AF OPERATION AND MAINTENANCE MANUAL

PS=
Purpose: Set a new target pressure and start a new pressure generation cycle.
Syntax:
“PS=n”
Arguments:
n: The target pressure in the current pressure units.
Remarks: The PPC2 AF will generate the given target pressure using the current generation settings &
mode. Generation will continue until a new target pressure is set, the PPC2 AF goes into
LOCAL mode, or an “ABORT” command is executed. If the given target is ‘0’ and the pressure
units are gauge, the PPC2 AF will vent.
The “PR”, “PRR”, “STAT”, or “SR” command can be used to monitor the progress of the
generation.
Example: Command: “PS=1000”
Reply: “1000.00 kPa a”
See Also: “PR”, “PRR”, “STAT”, and “SR” commands, 3.1.2.3, 3.2.3
PSF=
Purpose: Set a new target pressure and use just the fast speed to generate the pressure.
Syntax:
“PSF=n”
Arguments:
n: The target pressure in the current pressure units.
Remarks: The PPC2 AF will generate the given target pressure using just the fast speed, and will stop
generating when the pressure has reached or passed the given target. The system will not
attempt to hold the pressure.
The “PR”, “PRR”, “STAT”, or “SR” command can be used to monitor the progress of the
generation.
Example: Command: “PSF=1000”
Reply: “1000.00 kPa a”
Errors:

PSS=
Purpose: Set a new target pressure and use just the slow speed to generate the pressure.
Syntax:
“PSS=n”
Arguments:
n: The target pressure in the current pressure units.
Remarks: The PPC2 AF will generate the given target pressure using just the slow speed, and will stop
generating when the pressure has reached or passed the given target. The system will not
attempt to hold the pressure.
The “PR”, “PRR”, “STAT”, or “SR” command can be used to monitor the progress of the
generation.
Example: Command: “PSS=1000”
Reply: “1000.00 kPa a”
