AUTOMATIC ELECTRONIC DIAGNOSTICS
The faceplate computer has a self--diagnostic func-
tion for the electrical system (except input power
and water meter). The computer monitors electronic
components and circuits for correct
operation. If a malfunction occurs, the
computer attempts to self correct, dis-
playing ADJUST VALVE in the Normal
View Screen. If self correction fails, an
error code appears in the faceplate
display.
The chart below shows the error codes that could
appear, and the possible defects for each code.
While an error code appears in the display, all face-
plate keypads are inoperable except the SELECT
keypad. SELECT remains operational so the ser-
vice person can make the MANUAL
INITIATED ELECTRONIC DIAG-
NOSTICS, below, to further isolate
the defect, to check the water meter
and to send an E.A.S.E. transmission.

TROUBLESHOOTING,
MANUAL INITIATED ELECTRONIC DIAGNOSTICS
To enter diagnostics,
press the SELECT/EXIT
(
↵
) to enter the menu.
This screen contains in-
formation that can be
used to troubleshoot er-
rors. Use the (
↑
) and (
↓
)
keypads to scroll through all lines on this screen.
The first line shows time of day and error code.
Second line is
Pos:
which shows what position the
valve is in. Example: Service, Fill, Brining and Brine
Rinse, Backwash and Fast Rinse. The clock to the
right counts backward the time for each of the posi-
tions to be completed.
The next line is
Req Pos:
which is for requested
position, or what position the valve is travelling to.
Next line displays
Motor:
, either on or off, and
Sw:
(switch) either open or closed.
Next is
Trbn:
(turbine) and
Gals:
(gallons) which in-
dicate water meter operation as follows.
000 (steady) = conditioned water not in use...no flow
through the meter.
--open a nearby CONDITIONED WATER faucet--
000 to 151 (continual) = repeats display for each
gallon of water passing
through the meter. Gallons
up by one.
If you don’t get a reading in the display, with a faucet
open, pull the sensor housing from the valve outlet
port. Pass a small magnet back and forth in front of
the sensor. You should get a reading. If you
do get
a reading
, disconnect the outlet plumbing and
check the turbine for binding. If you
don’t get a
reading
, the sensor is probably defective.
