AUTOMATIC ELECTRONIC DIAGNOSTICS

The faceplate timer (PWA) computer has a self­
diagnostic function for the electrical system, except
for input power and water meter. The computer
monitors

electronic

components

and circuits for correct opera­
tion. If a malfunction occurs, an
error 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 but­
ton. SELECT remains operational so the service per­
son 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
DIAGNOSTICS

To enter diagnostics, press the SELECT button
and hold for three seconds.

You will see the following display, showing valve

(open

or

TURBINE OPERATION:

If no water is flowing

through the softener, the turbine indicator displays
three zeros. When water is flowing, the flow bar
scrolls across the display, and a 000 to 140 count re­
peats for each gallon of water passing through the
turbine. To check for positive operation of the tur­
bine 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 faucet
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.

POSITION SWITCH STATUS:

With the valve in ser­

vice, or any of the recharge cycles, the switch indica­
tor 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 indica­
tions vary from this pattern.
