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 elec- _--_-- Er r_
tronic components and circuits !
for correct operation. If a
malfunction occurs, an error
f
code appears in the face plate .......
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 buttons are inoperable except the SELECT
button. SELECT remains operational so the service
person can make the MANUAL INITIATED
ELECTRONIC DIAGNOSTICS (below) to further
isolate the defect, and check the water meter.

All of the preceeding displays show what position
the valve is in, if the turbine is operating, and the
position switch open or closed status.
o Press the ON/OFF-HOLD button to advance
the valve to the next position. To verify
component operation, or to possibly isolate a
defect, observe the following.
POSITION SWITCH STATUS: With the valve in
service, or any of the recharge cycles, the switch
indicator will show open -'_-. While the valve is
rotating from 1 position to another, the indicator
will show the switch closed -_-. A defect is
probable if indications vary from this pattern.
