AUTOMATIC
ELECTRONIC
DIAGNOSTICS
The
face
plate
computer
has
a
self-diagnostic
function
for the
electrical
system
(except
input
power and water meter). The computer
monitors the
electronic
components
and cir-
cuits for correct operation.
If a
_l-I-
I
malfunction
occurs,
an
error
code appears
in the face plate
display.
The chart below shows the error codes that couM
appear, and the
possible
defects for each code.
While an error code appears
in the display,
all face
plate
buttons
are inoperable
except
the SELECT
button.
SELECT remains
operational
so the service
person
can make the MANUAL INITIATED ELEC-
TRONIC DIAGNOSTICS
(below)
to further
isolate
the defect, and check the water meter.

To enter
diagnostics,
press
the
SELECT button
and
HoM for 3 seconds.
You will see the following
display,
showing
valve

((7)pen or
closed),
and turbine
operation.

TURBINE OPERATION.. If no water is flowing through
the softener,
the turbine
indicator
displays 3 zeros.
When water is flowing, the flow bar scrolls across the
display,
and a 000 to 199 count repeats
for each
gallon
of water
passing
through
the turbine.
To
check for positive operation
of the turbine
if zeros
are shown,
open
a nearby
soft
water faucet
and
observe
the turbine
count and flow bar.
If you don't get a reading in the display, with facuet
open, pull the sensor from the valve outlet port. Pass
a small magnet
back and forth in front of the sensor.
You should get a reading
in the display. If you get a
reading,
unhook the in and out plumbing
and check
the turbine
for binding.
