J.) RC-50 Control Box Features (Continued)
Electrode Status Icon
STEADY ON - NORMAL OPERATION
The electrode icon on the upper right side of the main screen indicates the electrical
polarity as well as its operational status. The pictures to the right show the electrode icon
switching from one polarity to the other. This will occur every ve minutes and allow the
electrodes to wear evenly to maximize the life of the electrodes.
BLINKING - CHECK ELECTRODE or WATER TDS TOO LOW
In this mode the electrode icon will blink. The output current indicator will also change
from the set to current value to the actual current value. The main cause for this to occur is
the TDS level of the water is too low. In most cases the TDS level will rise and no action is
required. Another reason for this warning is that the electrodes are worn out and need replacing. See the section
on Inspecting and Replacing the Electrodes for more information.
BLINKING with SHORT - SHORT CIRCUIT on ELECTRODE
This error mode is very unlikely to occur. If it should happen, most likely it will be caused by
something (usually a piece of metal) bridging (shorting) the electrode terminals. To correct the error
check the electrode terminals and wiring to make sure they are not touching each other. Also make sure no
foreign material is shorting out the electrode from inside the electrode chamber.
BLINKING with OPEN - OPEN CIRCUIT on ELECTRODE
This will most likely happen if one of the wires gets cut or otherwise disconnected from the electrode.
Check both terminals on the electrode, making sure they are connected and not excessively corroded.
Also make sure there are no nicks or cuts in the electrode cable.
Coil Status Icon
STEADY ON - NORMAL OPERATION
The coil icon on the right side of the main screen indicates the operational status of the
ScaleBlaster coil.
BLINKING - OPEN COIL
This indicates the coil has been disconnected from the RC-50 control unit. Check the red
and black binding post to make sure the coil wires are connected properly.
Output Current Indicator
This value indicates the output current owing through the electrodes. It
is adjustable from zero (OFF) to six hundred milliamps (mA) , in ve mA
increments.
