AUTOMATIC ELECTRONIC DIAGNOSTICS

The faceplate timer (PWA) computer has a self-

diagnostic		function			for	the	electrical		system,	except
for input		power	and		water		me-
ter. The	computer			monitors			elec-	......	I-	-I
ter. The	computer			monitors			elec-	....	i-r-i- _7
								....	i-r-i- _7
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 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 from outlet 2. Correct

defect 3. Plug in transformer 4. Wait for 8 minutes. The error code wilt return if the defect was not corrected.

MANUAL INITIATED ELECTRONICS

DIAGNOSTICS

_To enter diagnostics...

--from a error code display, press the SELECT 1 button.

--from a time display, press and hold the SE- LECT 1 button for 3 seconds.

You will see one 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.

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

If you don't get a reading in the display, with facuet 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.
