MANUAL INITIATED ELECTRONICS DIAGNOSTICS

1. To enter diagnostics, press the SELECT button and hold for 3 seconds.

You will see the following display, showing valve

cycle position, position switch status (open or

closed), and turbine operation.

valve position indicator turbine count (wa-

....... N NN		ter flowing)
		;	l_qo
		i	1''U
position switch	turbine	count (no
indicator (open)
	water	flowing)

TURBINE OPERATION: If no water is flowing

through the softener, the turbine indicator displays

3 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'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, unhookthe in and out plumbing

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 --M. While the valve is

rotating from 1 position to another, the indicator

will show the switch closed -,-,-. A defect is

probable if indications vary from this pattern.
