8. CONTROLLER
8.1. OVERVIEW
Ecosoft OC5000 process controller provides means to control operation of RO machine via
succinct user interface comprising two buttons and LED display. The controller is designed to
ensure complete automation of the process while allowing for manual intervention on user part at
any moment in time. When running a reverse osmosis machine, the controller executes the
following tasks:
• turning the unit on and off with respect to tank permeate level and/or backpressure switch
status;
• reading status of level, pressure, and stop switches; conductivity and temperature of permeate;
• going into Fault mode upon occurrence of any of the conditions indicating risk of damage to the
RO machine or improper operation;
• performing hydraulic flushing of membranes ('forward flush') with preset frequency and
duration;
• implementing manual control over the unit.
In order to deliver the above functionality, Ecosoft process controller supports the following
connectivity:
• 5 dry contact switches (NC/NO);
• 3 electrical valves (solenoid and motor driven valves can be used);
• alarm signal;
• high pressure pump, antiscalant and/or biocide dosing pumps;
• electrical conductivity probe with temperature sensor.
The controller supports scheduled maintenance alerts and passcode protected access to
configuration menu. Conductivity reading is digitally corrected for temperature of permeate, while
hardware interface offers good interference immunity and reliability with galvanically isolated
terminal connections.
