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 or motor driven valves can be used);
– alarm signal;
– high pressure pump, antiscalant and/or biocide dosing pumps;
– temperature and electrical conductivity probes.
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.
