aXPCB!
Get hardware
revision
This is derived by a resistor set in the
hardware.
aXPUMP
P
!
Get/set pump
(compressor)
statistics
Returns on-time, on-off count, and fault count.
P=
Z then statistics are zeroed
aXPR!
Get purge
pressure
Returns purge pressure setting in psi
aXPR
P
!
Begin/end purge
or
If
P
is B = begin purge mode
If
P
is E = end purge mode.
Set purge
pressure
Replace
P
with desired purge pressure (in psi)
Valid range is 20 to 90. Default :90
aXSH
P
!
Get/set stage
height value
Returns the value in current units.
If
P
=Z the stage offset is set to zero (does not
zero the stage reading, only the offset).
aXSL
P
!
Get/set slope
Range: 0.100 - 999.999
Used when the site requires non-standard
stage unit. See X command aXSUP! for the
built-in list of stage units.
Setting the slope will display “cu” (for custom)
in the Units field of the Set Stage screen. The
user must be aware of the units associated
with the input slope value
aXSO
P!
Get/set stage
offset in psi
Used when swapping a Bubbler and
replacement Bubbler is to use the same offset.
Before swapping the Bubbler, get and record
the offset
Swap Bubblers and then set the offset.
Although this command requires psi, the offset
displayed on the Bubbler’s screen and returned
as part of an M command will be in the
selected measurement units not psi.
