Scrolling Status Messages
The scrolling status message is located at the bottom of the main screen. Listed below are the messages and
their meanings.
1). UNIT FUNCTIONING CORRECTLY: Lets the user know everything is OK and that the control unit is
functioning.
2). CHECK ELECTRODE CONNECTIONS: A problem with the electrode connection has been detected.
Inspect the electrode wire connection to the electrode terminals, make sure they are well connected and there is
no corrosion. Also inspect the electrode cable and make sure there are no cuts or gouges.
3). INSPECT ELECTRODE FOR SHORTS: The control box has detected a short between the electrode
elements. This can be caused by a piece of metal physically touching both of the electrode terminals or by a
piece of metal inside the electrode chamber touching both electrodes.
4). CHECK COIL CONNECTIONS: The coil wire(s) has been disconnected. Check the wiring and the
black and red binding posts to make sure there are no loose or disconnected wires.
5). INSPECT ELECTRODE & MAKE SURE TDS IS NOT TOO LOW: This message will be displayed if
the user is setting the output current to a level that the control unit is unable to obtain. This is caused by the
electrode resistance being too high. This increased resistance can be caused by a wornout electrode or by a low
TDS level in the water. A TDS of 250ppm will allow a current flow of about 425-450 mA, with a new set of
electrodes.
Diagnostic Screen
This screen is used to display more technical information to the user or service technician. The following code
will access the Diagnostic Screen:
1) Turn the output current knob until the output current indicator is 005,
wait about two seconds and you will notice the electrode icon will switch
polarities.
2) Next dial in 030, and wait 2 seconds
3) Next dial in 015, and wait 2 seconds
The screen above should now be displayed. The control unit will return to the main screen when power is removed and
then reapplied. The user can also dial in the following code to return to the main screen:
