B.4 BUBBLER STATUS SCREEN FAULT INDICATORS
The Bubbler’s status screen only displays a single fault. The possible faults are prioritized so in the
case of multiple faults, the higher priority fault will be displayed. The following table lists the faults
in order of priority from highest to lowest.
BATTERY
Voltage has dropped below
minimum 8.0 VDC
1) Replace the battery. Voltage this low
results in deep discharge of battery and
it is unlikely to recharge and hold a
charge.
2) Check for possible causes for the power
supply system failure.
a) Ensure Bubbler has a direct power
source. It cannot be fully powered
through the Datalogger’s SDI port
(section 2.6.2)
b) Check power connections
c) Ensure solar panel is placed for
maximum sun exposure
d) Clean solar panel
e) Replace the solar panel with one
with a larger supply (the current
draw exceeds the supply of the
VOLTAGE_LOW
Voltage has
dropped below minimum 10.8 VDC
Check for possible causes for the power
supply system failure as in Step2 above
TEMPERATURE
Bubbler operating outside of its
temperature range
1) Take physical measures to protect
Bubbler from extreme environmental
conditions such as placing in a shelter.
COMPRESSOR Compressor failure Contact FTS Support.
LINE_HIGH
12
Blocked line
Indicates line pressure higher than
tank pressure or tank pressure >35
psi
1) Take action as described in Section B3 –
High Reading.
2) If fault continues after all apparent line
blockages have been cleared, contact FTS
Support.
TANK_LEAK
Triggered if tank pressure has not
increased by 0.5 psi after 10
seconds of compressor operation.
Contact FTS Support.
SYSTEM Internal misconnection/damage
12
Refer to section 3.4.1 for Bubbler behaviour if LINE_HIGH is due to tank pressure >35 PSI during a purge
