Diagnostic Screen (Continued)
1) Turn the output current knob until the output set value is 000 wait
about two seconds and you will notice the electrode icon will switch
polarities.
2) Next dial in 025, and wait 2 seconds
3) Next dial in 010, and wait 2 seconds
The control unit’s LCD display should now show the main screen.
The diagnostic screen monitors seven different operational values. Each value is described in detail below.
OUTPUT CURRENT SET This is the set point for the output current (in milliampere). The RC-50 will
maintain this amperage setting thru the electrodes.
OUTPUT CURRENT READING This is a measured current value (in milliampere) of the current owing
thru the electrodes. This value is an instantaneous value and may or may not indicate a steady state current
value. When in Analog Mode this reading will be the same as the current set value. When in Pulse Width
Modulation Mode this value divided by the Duty Cycle Value will equal the current set value.
DUTY CYCLE OF OUTPUT When in the pulse width modulation mode, this is the ON time of the current
output to the electrodes.
TOTAL HOURS UNIT HAS BEEN ON Total time (in hours) the RC-50 control unit has been powered ON.
OUTPUT VOLTAGE This is the output voltage across the electrodes. This voltage can range from 6VDC to
20VDC depending on the electrode conditions, water TDS, and output current setting.
LCD DISPLAY CONTRAST The LCD display’s contrast setting, in percentage.
ERROR STATUS NUMBERS This is a numerical representation of the present status. The Values and the
meaning are written below.
1) Normal Mode
2) Electrode Open Circuit
3) Electrode Short Circuit
4) Check Coil
5) Electrode Resistance Too High
LCD Contrast Adjust Screen
The LCD contrast adjustment screen allows the user to adjust the darkness of the LCD display. To access this
screen the user must dial-in the correct code on the output adjust knob. The following code will access the LCD
contrast adjustment screen.
1) Turn the output current knob until the output current indicator is
010, wait about two seconds and you will notice the electrode icon
will switch polarities.
