MESSAGE?
LOW FEED PRESSURE
The water pressure after the Progard TL Pack is < 0.3 bar.
Verify that the Feedwater supply is turned on. Verify that the
Progard TL Pack is not clogged (view the RO Reject Water in
FLUSH Mode). This Alarm is automatically reset during FLUSH
Mode if the water pressure problem is resolved.
Alarm Stop (Red LED
and System Stopped).
LOW PUMP PRESSURE
The RO Pump pressure is < 6 bar.
Set the pump pressure higher. Contact Millipore SAS for
assistance.
Maintenance (Yellow
LED).
PERMEATE < MINI
The Permeate Conductivity is measured as < 0.22
µ
S/cm (@
25
°
C). If the LOW TDS Option has been selected, then the Alarm
Value is < 0.06
µ
S/cm.
Verify that the Feedwater is not already purified (Very low
Feedwater Conductivity can lead to very low Permeate
Conductivity values).
Contact Millipore SAS for assistance.
Programmable – can be
set to any type of
message (Maintenance
by Factory Default).
PERMEATE > MAXI
The Permeate Conductivity is measured as > 194
µ
S/cm
(@ 25
°
C). If the LOW TDS Option has been selected, then the
Alarm Value is > 58
µ
S/cm.
Contact Millipore SAS for assistance.
Programmable – can be
set to any type of
message (Maintenance
by Factory Default).
PRODUCT CONDUCTIVITY <
MINI
The measured resistivity from the Polisher or Elix Module is too
high (> 94.9 M
Ω
.cm). The displayed resistivity may not show any
higher than 18.2 M
Ω
.cm. at 25
°
C.
Keep the Elix System in PRODUCTION Mode for a few minutes
to remove any air that could be trapped in the Resistivity
Sensor.
Contact Millipore SAS for assistance.
Programmable – can be
set to any type of
message (Maintenance
by Factory Default).
PRODUCT RES.<SETPOINT
Shown with Elix Systems not having a QGard Polisher. The
Product Water after the Elix Module is < the Product Resistivity
Setpoint (normally 10 M
Ω
.cm).
Let the system operate for an extended time (few hours) in
PRODUCTION Mode. Contact Millipore SAS if the message
continues.
Programmable – can be
set to any type of
