3.2 Operation with the H-350XL Pressure Sensor Attached
The following is a description of the H-350XL submenus used for configuring the bubbler.
Auto Purge Enbl[OFF]
Bubble Rate[XXX]/min
Purge Thresh[XXX]PSI
Purge Presur[XXX]PSI
Purge Time: [XXX]sec
Manual Purge: ENT=Y
Timed Prg: [XX] days
Tank PSI = XX.X
Diff PSI = XX.XX
Last Prg=MM/DD HH:MM
The H-350XL can sense when the orifice line is restricted or plugged. The system can be
configured to do an automatic purge of the orifice line when it becomes necessary. This menu item
turns the auto purge on or off.
Auto Purge Enbl[OFF]
This setting specifies the bubble rate that should flow from the end of the orifice tube. The
programmable range is 30 to 120 bubbles per minute.
Bubble Rate[XXX]/min
This setting sets the purge threshold. If the orifice line pressure reaches the purge threshold, the
H-350XL can initiate an auto purge. The range of “Purge Thresh” is 10 to 65 psi.
Purge Thresh[XXX]PSI
This setting is the pressure that the H-3551 uses to purge the orifice line. The range is 15 to 80 psi.
Set this value to a pressure which would reasonably purge sediment and debris from the orifice.
Keep in mind that the higher pressures require more energy from the battery.
