VALVE
Get/Set
Turns on/off solenoids to set the DSA into one of the many valve states, or retrieves the DSA's
current states. The internal valves will only change modes when 90-120psi control pressure is
available at the DSA control pressure input.
VALVE <mode>
Where <mode> is:
PX = enables measurement mode (all solenoids off)
ISO = enables isolate mode (CTL1 on, CTL2 and PRGCTL off)
CAL = enables calibrate mode (CTL1 and CTL2 on, PRGCTL off)
PRG = enables purge mode (all solenoids on)
VALVE <mode> [<solenoid pattern>]
Where <mode> is one of the options above.
Where [<solenoid pattern>] is a 3 digit bit code for the enable/disable of the three solenoids,
where CTL1 is the least significant bit (only seen when <mode> is UNK).
- and/or -
Prompt when ready to accept a new command.
PX
// Change the valve state to PRG mode
VALVE PRG
>
// Retrieve the current DSA mode (when not in a typical mode)
VALVE
VALVE UNK 0x4
>
// Retrieve the current DSA mode
VALVE
VALVE CAL
>
The DSA will not accept UNK or a bit value as an argument.
CTL1
Get/Set
Activate or deactivate solenoid number 1 (CTL1), or retrieve the current status.
CTL1 <state>
Where <state> is:
0 = off (closed/disabled)
1 = on (open/enabled)
CTL1 <state>
- and/or -
Prompt when ready to accept a new command.
