C-75 INTRODUCTION
INSTALLATION
1. The RO pump motor or motor starter and the solenoid valves must be of the same voltage 120 or 240 volt.
2. Confirm that the (3) input signals - pressure switch, tank level switch and pretreat switch are all of the same configuration,
normally open or normally closed.
3. Confirm the desired switch settings for your operation. The switches are factory set to the OFF Position: Auto Reset
(disabled), Pressure Fault Retry (disabled), Tank Full restart time delay (2 seconds), Input contact type (NC, open to operate).
If you desire to change any switch functions, move that switch to the ON Position. [See table below].
4.
Wire to the controller as follows:
•
Remove the enclosure cover.
•
Mark and drill necessary electrical entry holes in the empty enclosure.
•
Terminate necessary wiring to the Quick Connect terminals as required (See diagram on page 4). Each terminal is
labeled for the proper connection. Terminals P1-P9 are high voltage for power, motor, inlet and flush solenoid. Utilize proper
3 conductor wire size for the appliance.
WARNING:
The controller is rated for maximum 20 amp total load. Terminal strip P11 is dry contact for input signals from tank full,
pressure fault and pretreat lockout. Use small gauge 2 conductor cable for these wire connections.
5.
Position and mount the enclosure in the desired location.
6.
Connect all wiring to the appropriate appliances (Do not connect to the power source at this time).
7.
Reassemble the enclosure, be sure to coil and leave some slack wire inside the enclosure.
8.
Connect the power wire 120- 240 volt to its source.
9.
Proceed to push the power switch ON and test the completed unit as necessary.
10.
Notice the status LED to confirm system status.
The Advantage Controls Series 75 RO controller is designed for the small commercial Reverse Osmosis system. This
controller incorporates relay outputs and dry contact inputs to either run or shutdown as necessary for proper operation.
The S75 Controller has up to three relay outputs: inlet solenoid valve, RO pump motor, and an optional flush solenoid
valve.
The Series 75 Controller is designed for the small commercial Reverse Osmosis system. This controller incorporates relay
outputs and dry contact inputs to either run or shutdown as necessary for proper operation. The S75 Controller has up to
three relay outputs: inlet solenoid valve, RO pump motor, and an optional flush solenoid valve.
The controller’s three inputs will monitor the inlet pressure, tank level, and pretreatment lock. An LED on the front of the
controller will visually indicate the operating status of the RO unit. The S75 can operate a one horse power single phase
pump motor directly with the RO pump relay output. This controller provides crucial time delays required to prevent the
RO unit from false shutdowns.
