BUILT-IN DIAGNOSTICS
The
Commander II Model JC5
Control Box contains a way to display a diagnostic report on its operation. It allows the user to view
the salt concentration, the water temperature, and the Electrolytic Cell voltage and amperage. This is provided for a technician to
evaluate the performance of the Commander II Model JC5 without the need for special equipment. The values are measured by
counting the number of flashes of the lights, as described below.
To access and interpret the diagnostics, follow this procedure:
To start the diagnostic procedure, press and hold both the UP and DOWN buttons at the same time. Hold them pressed until
the output display lights go out, leaving just the bottom light illuminated (about 5 seconds).
1.
The
first
value to be displayed is the
salt concentration
in Parts Per Million (PPM). This value is measured by counting
the number of flashes of the top 3 lights. In the case of salt, the top light is not used, the next to the top flashes the 1000’s
digit and the third light flashes the 100’s digit in ppm.
Example: 2 flashes/pause/8 flashes/pause Read: 2,800 PPM
2.
The
second
value is the
water temperature
in degrees Fahrenheit. When this is displayed, the second light from the
bottom is on. The top light flashes the 100’s digit, the next the 10’s digit and the next the units of temperature.
Example: 8 flashes/pause/6 flashes/pause Read: 86 Degrees F
3.
When the
third
light from the bottom is on, the
cell voltage
is displayed. The top light is not used. The second light
flashes the 10’s digit and the third the units of voltage.
Example: 2 flashes/pause/8 flashes/pause Read: 28 Volts
4.
When the
fourth
light is on the
cell current
in amperes is being displayed. The top light displays the 10’s digit (not
normally used), the next the units and the third the tenths of amps.
Example: 5 flashes/pause/5 flashes/pause Read: 5.5 Amps
