INSTRUCTION MANUAL ECOSOFT RO SYSTEM MO6500BWTSS
Pushing STOP will bring the controller to Stop mode. Pushing START will take the controller
into Service if permeate is low and backpressure switch is inacve. Otherwise, pushing START
will iniate Forward Flush 1 and Forward Flush 2 (if set) and then bring the controller back to
Standby. When oat switch or permeate backpressure switch deacvate, the controller will go back
to Service.
FAULT
In Fault mode, the unit is stalled to protect the equipment from dangerous operang condions.
Fault mode is brought on by acvang low feed pressure switch (to prevent ‘dry running’), high
feed pressure switch (to protect against overpressure), or reading an excessively high permeate
conducvity value (which could mean membrane rupture or other malfuncon if conguraon
step 1.16 is set to non-zero value.).
Fault mode can only be quit manually by pushing START. Ensure the cause of fault is eliminated
before quing Fault mode. Pushing STOP will bring the controller to Stop mode.
STOP
In Stop mode, the unit is stalled and awaing further input. Stop mode can be manually brought
on by pushing STOP in any mode, or by stop switch opening circuit between STOP terminals on
the printed circuit board.
Upon pushing START or deacvang stop switch, the controller will resume from where it was
interrupted.
