AUTOMATIC ELECTRONIC DIAGNOSTICS

The faceplate timer (PWA) com-

puter has a self-diagnostic func-

tion for the electrical system, ex- E r F _ _ cept for input power and water

meter. The computer monitors electronic compo-

nents and circuits for correct operation. If a malfunc-

tion occurs, an error code appears in the faceplate display.

MOST LIKELY _"

CODE_"

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.

A.The first 3 digits indicate water meter operation as follows:

000 (steady) = Soft water not in use, and no

flow through the meter.

--OPENA NEARBY SOFTWATER FAUCET--

000 to 199 (continual) = Repeats display for each

gallon of water passing through the meter.

If you don't get a reading in the display with faucet

open, pull the sensor from the vane 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.
