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 flash red. To clear the pressure fault, press the power
key twice.
