INSTRUCTION MANUAL ECOSOFT RO SYSTEM MO6500BWTSS
When operang, the controller will be in any one of the following modes: Service, Stop, Forward
Flush 1, Forward Flush 2, Standby, Fault. Immediately aer starng, the controller will display
rmware version and then proceed to Service if tank permeate level is low and backpressure switch
is not acvated.
Here and below informaon is relevant to the rmware version “OC5000EC ver_03”. For
informaon on dierent rmware versions please contact your technical support.
Conguring and manipulang the controller is done using START and STOP buons. Current
mode of operaon and pertaining informaon is shown on the LED display. Opening the circuit in
the Stop domain of terminal block (see gure 1) will bring the controller to Stop mode regardless of
its current mode of operaon. Closing the circuit will take the controller back to the mode that had
been interrupted. Stop terminals can be used to connect a microswitch on pre-treatment media
lter, a relay or other means of external control to the controller.
Following is the descripon of controller modes.
SERVICE.
In Service mode, the RO machine produces permeate. If no fault condions are taking place, oat
switch is low and backpressure switch is not acvated, the controller will operate in Service mode.
Display will ash cumulave runme of the RO machine, remaining me before scheduled
maintenance alert (if set in conguraon step 3.1), temperature and conducvity of permeate
(or TDS of permeate if conguraon step 1.15 is set to “on”). Pushing START once will iniate
Forward Flush 1, pushing START twice in 0.5 seconds or less will iniate Forward Flush 2 (if
conguraon step 1.3 is set to non-zero value), pushing STOP will bring on Stop mode. If high
feed pressure, low feed pressure, or high permeate conducvity condion occurs, the controller
will go into Fault mode.
FORWARD FLUSH 1
During Forward Flush 1, membranes are rinsed with high ow of raw water allowing concentrate run
freely to drain. Forward Flush 1 occurs during normal operaon with frequency set in conguraon
steps 1.5, 1.6. It is also acvated in Service mode if the controller is going to transion to Standby
aer reading high tank level or high permeate pressure. It can be manually acvated while in Service
by pushing START buon.
