The faceplate timer (PWA) computer has a self-diagnostic

function for the electrical system, except put power and

water meter. The computer monitors electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the faceplate display.

The chart below shows the error codes that could appear,				_ ___	_
and the possible	problems	for each	code.			FIG. 60

While an error code appears in the display, all faceplate buttons are inoperable except the SELECT1 button. SELECT1 remains operational so the service person can make the MANUAL INITIATED ELECTRONIC DIAGNOS-

PROCEDURE FOR REMOVING ERROR CODE

FROM FACEPLATE:

1.• Unplug transformer from outlet.

•Plug in transformer.

•Wait for 8 minutes.

2.• Unplug transformer from outlet.

•Correct problem.

•Plug in transformer.

•Wait for 8 minutes.

The error code will return if the problem was not corrected.

MANUAL INITIATED ELECTRONICS DIAGNOSTICS:

To enter diagnostics, press the SELECT1 button and hold for three seconds. The display will show valve cycle posi- tion, position switch status (open or closed), and turbine operation. See Fig. 59.

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 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'tget 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 plumb- ing and check the turbine for binding.

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 one position to anoth- er, the indicator will show the switch closed. A defect is probable if indications vary from this pattern.
