Brine flow sensor fault detected.
Possible sensor failure. By-pass to
continue.
The brine water flow meter is no longer sending signals
into the controller. The sensor could be unplugged, a
wiring fault may exist, or the sensor itself may have
failed. Automatic operation is not available. The sensor
must be fixed or replaced before Automatic mode is
available. If an emergency exists, the system can still be
run in automatic mode by activating the sensor by-pass
function. Please contact your dealer for help.

High pressure pump inlet pressure
low. Please check filtration for high
fouling.
Inlet pressure to the high-pressure pump fell below
minimum allowable set-points. This is usually
attributed to booster pump cavitation (air in the feed
line), a filter is clogged, or a large system leak. Check
your system for leaks, and check feed lines for possible
air vacuum leak. If none of these conditions exist,
change your filtration elements and attempt to re-start
the system again.
13
High pressure pump inlet pressure
high. Pump damage can occur if
started.
Inlet pressure to the high-pressure pump is above
maximum allowable set-points. This is usually
attributed to feed line over pressurization, check your
incoming feed water line for malfunction of any
boosting devices installed, and finally check rotation
direction of the high pressure pump itself. If incorrect
rotation is present this can cause over pressurization of
the feed line. Lastly check that any high-pressure check
valves installed are functioning correctly.
14
HP pump inlet sensor in by-pass &
HP pump outlet pressure low.
Possible cavitation
The system was operating with the high-pressure pump
inlet sensor in bypass mode. During operation, the
high-pressure pump achieved minimum allowable
outlet pressure, but then outlet pressure dropped
below the low set point. This is a good indication to the
controller that pump cavitation was occurring. The
system was stopped to protect the pump from damage.
Follow the items listed in fault description 12 above, to
locate the possible reason for this pump inlet
cavitation.
15
HP pump inlet sensor & HP pump
outlet sensor in by-pass. Operation
not possible.
The user has requested that both the inlet pressure
transducer and outlet pressure transducer of the high-
pressure pump be set into bypass. Requests for this
state are usually not permitted by the bypass screen
manager. However, if for some reason these settings
have been allowed, the unit will fail an automatic
startup attempt as with both sensors bypassed, it is
impossible to apply any protective measures to ensure
high pressure pump failsafe operation. Deactivate one
of these sensor bypasses to continue. If both sensors
are malfunctioning, the unit cannot be run until at least
one sensor is fixed or replaced.
