8.6 ALARM-06: HIGH INLET PRESSURE TO RO MEMBRANE UNIT
The error occurs when the osmosis pump is in process, and there is no signal from the HPS-02 high-pressure
sensor at the membrane inlet for 10 seconds . After a problem occurs, the system will try to restart it again. If the
problem persists, the osmosis system will stop until the problem is resolved.
8.7 ALARM-07: RO PUMP OVERLOAD
The error occurs when a signal is received from the thermal protection of the pump motor of the RO system P-
01.
8.8 ALARM-08: HIGH ELECTRICAL CONDUCTIVITY OF PERMEATE
The error occurs when the pump of the RO system is working, the system is not in flushing mode or CIP, and the
conductivity value of the RO system permeate is bigger than the set value (Setup-04) for 5 minutes. After a
problem occurs, the system will try to restart it again. If the problem persists, the osmosis system will stop until the
problem is resolved.
Solution: Check RO pump P-01 and overload protection switch (inside the
control box) functionality.
Solution: The system can be reset manually by pressing the reset button or
by automatic reset every three hours. Perform PCP-01 calibration, perform
CIP, or change the membrane.
Solution: The error can be fixed manually by pressing the reset button or by
automatic reset every three hours. Perform CIP or change the membrane,
check HPS-02 functionality.
