This manual was produced by the manufacturer of the ROC-2015 controller.
: Allows for remote or panel-switched control.
Instructions on how to use the front panel interface, read diagnostics, change setpoints, and monitor system performance.
: When the system is powered or the tank is empty, the controller opens the inlet solenoid valve and activates the high-pressure pump . It often begins with an automatic flush cycle to rinse the membranes.
: Ensure the conductivity sensor is connected to the designated shielded terminals to prevent interference. Connect the "Low Pressure," "High Pressure," and "Tank Full" switches to the digital input ports. Calibration : Access the menu to set the electrode constant (usually 1.0 c m to the negative 1 power
Search for "Analog Input Overrange" . The manual explains that the raw A/D count can go up to 16383 (20mA) but the EU (Engineering Unit) scaling must be recalibrated using a precision loop calibrator. It provides the two-point calibration procedure.
For full installation and wiring diagrams, you can access documentation from retailers and manufacturers like Chiwatec or detailed technical manuals hosted on platforms like Scribd and EcoUnit . RO program controller ROC-2015 - chiwatec
Proactively shuts down the entire system during overpressure events.
: The front panel uses LED lamps to indicate specific states such as "Low Feed Press," "Low Press," and "ALA" (Alarm).
Stops the system when the storage tank is full.
