Permeate µS level to high
Fault
code: Cause
Solution
601
Membrane production pressure < 10 bar.
•
Adjust membrane pressure to 10-12 bar. Default setting 10 bar.
602
Drain is blocked or adjusted wrong.
•
Re-adjust drain volume and flush membrane.
603
Supply water quality is outside recommended max values.
•
Check that all pre-filtration is OK.
•
1 µ filter mechanical filters.
•
Softener.
•
Carbon filter.
•
Sand filter.
•
Take out a water report.
604
Membrane is worn out or defected.
•
Replace membrane.
Permeate water production volume to low
Fault
code: Cause
Solution
701
Automatic fuse to production pump turned off.
•
Turn the fuse back on.
- If it turns back off, see 301-303.
702
Membrane pressure set to low.
•
See 601.
703
Drain blocked or adjusted wrong.
•
See 602.
704
1. Additional machinery has been connected to RO. Some
machinery is requiring a big amount of water within a short
time (e.g. print machinery)
2. Humidification system has been expanded, so water demand is
higher than production capacity.
1. Minimize the max flow l/min to equipment to avoid the permeate
tank emptying. Or insure that the equipment stops before tank reach
low level sensor.
2. Add extra capacity to existing system or add an extra RO system.
705
Over time the membrane loses capacity. When the total capacity is
less than demand, the system goes in to alarm.
•
Replace membrane.
706
Membrane is worn out.
•
See 705.
Supply pump CM3 unable to maintain pressure
Fault
code: Cause
Solution
801
Air in supply pump caused by empty tank.
•
System in alarm. Follow the guide depending on the alarm.
code 100-500
802
Water demand is bigger than what the pump can supply.
1. Reduce the output max flow.
2. Add extra water / pump capacity.
803
Pump or PM2 is defect.
•
Replace.
