Accurate wiring prevents board burnout and ensures accurate sensor readings. The rear terminal strip of the ROC-2015 is divided into high-voltage relay outputs and low-voltage sensor inputs. High-Voltage Terminals (Power & Relay Outputs)
Periodically inspect all wiring for corrosion or loose connections. Common Troubleshooting:
Locate the small potentiometer or digital menu button on the side/rear of the casing (model variant dependent).
The null-modem pinout. On page 3-12 (depending on revision), the manual shows that while the ROC-2015 uses a standard DB9 connector, it requires a null-modem cable (pins 2 and 3 crossed, pin 5 straight). A straight-through cable will never connect. roc-2015 controller manual pdf
When the product water tank float switch triggers a "Tank Full" signal, the controller safely shuts down the high-pressure pump, closes the inlet valve, and displays "TANK FULL." 4. Low-Pressure Protection
Monitors the product storage tank. It opens when the tank is full and closes when water levels drop.

Detection for low level in the raw water tank or low pipeline pressure. Tank Level
These dry contact inputs signal the controller regarding system pressures and tank levels.
This manual was produced by the manufacturer of the ROC-2015 controller. A straight-through cable will never connect
The flush valve closes, and the high-pressure pump activates. Water forces through the membrane, and the display updates with live conductivity readings. 3. Full Tank Standby
Before you download a random PDF, check your unit’s firmware.
: Monitors the pure water tank level to stop production when full.
This controller is a testament to modern water treatment automation, offering an "all-in-one" solution that minimizes the need for external components. It seamlessly integrates control of multiple system components, including inlet valves, low-pressure and high-pressure pumps, and flush valves, into a single, compact unit. The ROC-2015 is also known as a cost-effective upgrade to the earlier RO-2008 and RO-2003 models.
