I-ROC150S RO Controller Installation and Setup
Introduction
The Applied Membranes Inc. Series 150 controller is a state-of-the-art control system for commercial and industrial
reverse osmosis systems. The Series 150 is a microprocessor-controlled system that can monitor pressure and level
switches. A TDS monitor/controller with programmable set-points is an integral part of the Series 150. The Series 150
displays system status and sensor and switch input status using an easy to ready backlit LED display.

Relay Outputs
•
RO pump relay: 120/240VAC, 1HP
•
Inlet valve relay: 120/240VAC, 5A
•
Flush valve relay: 120/240VAC, 5A
Note: Relays supply the same output voltage as the board power (120 or 240 VAC).
Power Wiring
Refer to illustration 4 and the following drawings for terminal strip and jumper locations. Before applying power to the unit.
AC power for the unit is connected to terminal strip P1. Connect the ground wire of the AC power to the terminal
labeled GND. For AC power with a neutral and hot wire, the hot wire connects to L1 and the neutral wire connects to
L2. For AC power with 2 hot wires, either wire can connect to L1 and L2.
The Series 150 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.
