AUTOMATIC ELECTRONIC DIAGNOSTICS
The faceplate timer (PWA) computer has a self-diag­
nostic function for the electrical system, except for
input power and water meter ■ fsitr 9
g W| " _
The computer monitors the elec- - - trrii
tronic components and circuits
for correct operation. If a mal­
function occurs, 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 enror 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.

PROCEDURE FOR REMOVING ERROR CODE FROM FACEPLATE: 1. Unplug transformer 2. Correct defect
3. Plug in transformer 4. Wait for 6 minutes. The error code will return if the defect was not corrected.
MANUAL INITIATED ELECTRONICS DIAG­
NOSTICS
1. To enter diagnostics...
—from a error code display, press the #1 SELECT
button.
—from a time display, press and hold the #1
SELECT button for 3 seconds.
You will see 1 of the following displays. All of the
displays show what position the valve is in, if the
turbine is operating, and the position switch open or
closed status.

2. Press the ON/OFF-HOLD button to advance the
valve to the next position. To verify component
operation, or to possibly isolate a defea, observe
the following.
POSITION SWITCH STATUS: With the valve in service,
or any of the recharge cycles, the switch indicator will
show open -N-, 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.
WATER METER TURBINE: With soft water in use, the
turbine flow rate display continually repeats a 000 to
140 count for each gallon of water passing through the
turbine. The display will remain a steady...000 if soft
water is not in use (open a nearby soft water faucet to
check).
If you don’t get a reading in the display, with faucet
open, pull the sensor from the valve outlet port. Pass a
small magnet back and forth in front of the sensor. You
