Startup Sequence/Operating Window
The RIO Series OSG goes through a start-up sequence that includes brine proportion pump
activation and purging the cell of warm water. When power is applied to the cell, the current
flowing through the cell is measured. During normal operation, the amperage will fluctuate
slightly. Approximate amperage for each RIO M cell module is 200 amps and for each RIO H
cell module, 225 amps. If the cell amperage is too high, the brine flow rate is reduced by
slowing the pump; conversely, too low an amperage is corrected by speeding up the pump.
The cell amperage will increase until it stabilizes in the optimal operating range, the operating
window. Cell voltage and current are indicated on the Main Display screen (Figure 32). The
brine proportion pump will also step up or down, but the pump control voltage, indicated as
Brine Pump Voltage, should be between 0 and 5 VDC.
When the operating window is reached, the electrolytic cell will begin to produce oxidants and
fill the oxidant tank. When the oxidant storage tank is filled to the high level, the level sensor
places the OSG into standby mode. When the oxidant storage tank is drained of oxidant
solution below the bottom level sensor, the OSG will automatically restart and run until the
oxidant tank is filled to the highest level.
When the OSG goes into standby mode, the OSG controller goes through a purge sequence to
remove brine from the lines and cell. Brine in the cell can cause an adverse battery effect that
can shorten the life of the cell. During the shutdown sequence, the brine proportion pump will
turn off. After 90 seconds the water solenoid valve will also turn off and the cell will power off.
