AUTOMATIC ELECTRONIC DIAGNOSTICS

The face plate computer has a self7diagnostic function for the electrical system (except input power and water meter). The computer monitors the electronic components and circuits

for correct operation. If a malfunc7 tion 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 button. The SELECT button remains operational so the service person can make the Manual Initiated Electronic Diagnostics to further isolate the defect, and check the water meter.

MANUAL INITIATED ELECTRONIC DIAG- NOSTICS

1.To enter diagnostics, press and hold the SELECT button until 000 - - shows in the display.

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

000 (steady) = Soft water not in use, and no flow through the meter.

￿ OPEN A NEARBY SOFT WATER 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 the 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.

…

B.The letter (P) and dash (or dashes) indicate POSI7 TION switch operation. If the letter appears, the switch is closed. If the dash shows, the switch is open.

Use the ON/OFF7HOLD (Recharge Now) button to manually advance the valve into each cycle and check correct switch operation.
