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			I	_l-I-	I
and	circuits		for correct		opera-		L
tion,	If	a malfunction		occurs,		an
error	code		appears	in	the	face-
_late	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.

POSSIBLE DEFECT

CODE	MOST LIKELY _	_	LESS LIKELY
Err1, Err3,	motor inoperative / wiring harness or connection	to switch / position switch / valve	defect causing
Err4	hiplh torque
Err5	faceplate timer (PWA)

PROCEDURE FOR REMOVING ERROR CODE FROM FACEPLATE: 1. Unplug transformer from outlet 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

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

You will see the following display, showing valve

cycle position, position switch status (open or closed), and turbine operation.

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.

_TURBINE SUPPORT AND

SHAFT

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 199 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.

VALVE

OL

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.
