C-100 INTRODUCTION
MODEL BUILDING AND GENERAL SPECIFICATIONS
The Advantage Controls C-100 RO controller is a state of the art control system for commercial and industrial reverse
osmosis systems. The C-100 is a microprocessor-controlled system that can monitor pressure and level switches. A TDS
monitor/controller with adjustable limit is an integral part of the unit. The S100 displays system status and sensor and switch
input status using a status LED and a 3-digit LED display.

INSTALLATION
Mounting
Mount the S100 in a convenient location on the RO equipment using the integral mounting anges.
Power Wiring
WARNING: Before applying power to the unit, verify that the voltage jumpers are congured correctly for the voltage
that will power the unit. The voltage jumpers are located below the transformer. For 120 VAC operation, there should
be a wire jumper installed between J1 and J3 and a second wire jumper installed between J2 and J4. For 240 VAC
operation, a single wire jumper should be installed between J3 and J4.
AC power for the unit is connected to terminal strip P1. Connect the ground wire of the AC power to P1-1 (GND). For AC
power with a neutral and hot wire, the hot wire connects to P1-2 (L1) and the neutral wire connects to P1-3 (L2). For AC
power with 2 hot wires, either wire can connect to L1 and L2.
Pump and Valve Relay Outputs
The S100 supplies relay outputs to control the RO pump
and solenoid valves.
NOTE: The relays output the same voltage as the AC
power to the board. If the pump and solenoids operate
on different voltages, a contactor will need to be
supplied to operate the pump.
RO Pump Wiring
The RO pump connects to P1-4 ( L1) and P1-5 (L2) RO
pump terminals. This output can operate 120/240VAC
motors up to 1HP directly. For motors larger than 1HP or
for 3 phase motors, this output can be used to operate a
contactor.
Terminal Strip and Jumper Locations
Inlet and Flush Valve Wiring
The inlet and ush valves must operate at the same voltage as supplied to the board. These outputs can supply 5A maximum
and are not designed to operate pump motors directly. If these outputs are to be used to operate a boost or ush pump, the
output should be used to operate a contactor. The inlet valve connects to P1-6 (L1) and P1-7 (L2) inlet terminals. The ush
valve connects to P1-8 (L1) and P1-9 (L2) ush terminals.
TDS / Conductivity Cell Wiring
For accurate TDS readings, the cell should be installed in a tee tting where a continuous ow of water passes over the cell
and no air can be trapped around the cell. The cell is connected with 5 wires to terminal strip P3. Connect each colored wire
to the terminal labeled with the same color.

INSTALLATION
Switch Inputs
Switch inputs are connected to P2. The connections for these inputs are not polarity sensitive and can be connected to either
terminal. The switch inputs should be dry contact closures only.
WARNING: Applying voltage to these terminals will damage the controller. The switches can be either normally open or
normally closed, but all switches must be the same. If the controller is set for normally open switches, all switches must be
open for the unit to run. If the controller is set for normally closed switches, all switches must be closed for the unit to run.
NOTE: J10 selects normally open or normally closed operation. When J10 is in the A position, the unit is congured for
normally open switches. When J10 is in the B position, the unit is congured for normally closed switches.
Pressure Fault Switch
On systems where a low feed pressure shut down is required, a feed pressure switch can be connected to the pressure fault
input of P2. If a high pump pressure shut down is required, a high pressure switch can be connected to this input. If both low
feed pressure and high pump pressure shut down are required, both switches can be connected to this input. Both switches
must be either normally open or normally closed to operate properly.
Pretreat Switch
In systems with pretreatment, a pretreat lockout switch can be connected to the pretreat input of P2. This switch should
operate when the pretreatment device is out of service.
NOTE: The output from the pretreatment device must be a dry contact and must not supply voltage.
Tank Full Switch
Connecting a tank full switch to the tank full input of P2 can cause the unit to shut down for a tank full condition. J9 selects a
short or long tank full restart.

SYSTEM OPERATION
Operation
The C-100 has 2 modes of operation, a standby mode and an operating mode. In the standby mode,
the unit is effectively off. All outputs are turned off and the display shows OFF. In the operating
mode, the unit operates automatically. All inputs are monitored and the outputs are controlled accordingly. Pressing the Power
key will toggle the unit from standby to operate or from operate to standby. If power is removed from the unit, when power is
reapplied, the unit will restart in the mode it was in when power was removed.
Display and Status Indicators
The display is a 3 digit display. System operating status, the TDS reading and the TDS setpoint are shown on this display. A
red/green LED indicates the system status in conjunction with the display.
RO Start Delay
When the controller is placed in the operating mode or restarts from a shut down condition, the inlet valve will open and a
5 second time delay will start. During the delay, - - - will show on the water quality display. After this delay, the RO pump will
start. The water quality display will now show the current water quality. The status lamp will show steady green.
Pressure Fault
If the pressure fault input is active for 2 seconds, a pressure fault condition will occur. This will cause the controller to shut
down. PF will show on the water quality display and the status lamp will ash red. To clear the pressure fault, press the power
key twice.

SYSTEM OPERATION
PF Auto Reset / PR Retry
With J8 in the A position, the power must be cycled using the Power key to clear a pressure fault shut down.
A PF auto reset function is enabled by placing J8 in the B position. When a pressure fault occurs with the PF
auto reset enabled, the controller will automatically reset after a 60 minute delay and the controller will start. If
the pressure fault has cleared, the controller will continue to run. If the pressure fault condition is still active, the
controller will again shut down for the pressure fault condition and the auto reset cycle will repeat. During the
auto reset delay, the water quality display will show PF and the status lamp will be off.
A PF retry function is enabled by placing J8 in the C position. When a pressure fault occurs with the PF retry
enabled, the controller will shut down for 30 seconds and then attempt to restart. If the pressure fault is still
active, the controller will shut down for 5 minutes and then attempt to restart. If the pressure fault is still
active, the controller will shut down for 30 minutes and attempt to restart. If the pressure fault is still active,
the controller will lockout for the pressure fault. During the retry delays, the water quality display will show
PF and the status lamp will be a steady red. If during one of the retries, the controller is able to start and run
continuously for 10 seconds, the retry function is reset. If a pressure fault occurs, the PF retry cycle will repeat
from the beginning.
When J8 is in the D position, both the PF auto reset AND the PF retry functions are enabled. If a pressure fault
condition occurs, the PF retry function will operate as described above. If the retry function locks out, the PF
auto reset function will operate as described above. The PF retry and PF auto reset functions will continue.
Tank Full
If the tank full input is active for 5 seconds, the controller will shut down for a tank full condition. The water
quality display will show FUL. When the tank full condition clears, the unit will restart after the selected restart
delay. The delay is selected with J9. With J9 in the A position, the restart delay is 2 seconds. With J9 in the B
position, the restart delay is 15 minutes. Position A is normally used with tank level switches that have a large
span. During the restart time, the status lamp will ash green.
Pretreat Lockout
If the pretreat lockout input is active for 2 seconds, the controller will shut down for a pretreat lockout condition.
The water quality display will show PL. When the pretreat lockout condition clears, the unit will restart.
Membrane Flush
A ush function can be enabled using J11 and J12. When a ush is initiated, the ush valve will operate and the
ush will last 5 minutes. The ush can occur when a tank full condition occurs or every 24 hours, depending on
the jumper settings. The inlet valve can be open or closed and the RO pump can be on or off, depending on the
jumper settings.

SYSTEM OPERATION
Water Quality Display
The water quality display shows the current water quality when the controller is operating normally and
status messages when the controller is shut down. The water quality display is 0-999 PPM. If the water
quality is above 999, the display will show ^ ^ ^. If the water quality is below the setpoint, the water
quality lamp will be green. If the water quality is above the setpoint, the water quality lamp will be red.
Water Quality Setpoint
The water quality setpoint can be adjusted from 0-999. If set to 999, the water quality lamp will always
remain green. To set the water quality setpoint, press the Setpoint key. The display will alternate
between the setpoint and SP. Use a small screwdriver to adjust the SP adjustment to the desired
setpoint value. Press the Setpoint key to return the display to the water quality display.
Calibration
To adjust the calibration of the water quality, measure the water with a meter calibrated to a known
standard. Using a small screwdriver, adjust the CAL adjustment to get the correct reading on the
display.
