Introduction
Definition
This Service Manual contains Troubleshooting and Electronic Components
information for the ELIX/RIOS/AFS-D/AFS-E systems – Essential Range.
Troubleshooting Card
• A Troubleshooting Card (TC) is represented as a diagram. This diagram
describes a sequence of actions to follow. This aids in troubleshooting a
particular problem with the water system.
• Each action to complete is written in an Action Box (square box). Detailed
information can be found by clicking on . Electrical component testing
information can be found by clicking on .
• Troubleshooting Cards are classified into categories depending on the nature
of the issue (see the Summary of Cards table for more information).
Electronic Components Card
An Electronic Components Card (EC) describes an electrical component found
in the water system.
Each EC is divided into several topics including:
• Description and location,
• Structure and characteristics,
• Electrical connections and software interaction, and
• Circuit and component tests.

Water systems The water systems are composed of two distinctive parts :
The first portion of the system is called the RO portion or the RO/EDI portion
composition
if the system includes an EDI Module. All the systems of the Essential range
incorporate a RO or RO/EDI portion.
The second portion is called the Distribution portion for systems that include a
Distribution part (AFS). The Rios and Elix systems do not incorporate
Distribution portion.

TC001 – Er:03 = RO Permeate Water Conductivity > SP
Type of message : Alarm Stop
Default Set Point value : 100 μS/cm @25°C (system with EDI)
200 μS/cm @25°C (system without EDI)
Why?
The RO Permeate Water Conductivity is > SP in either Rinsing
mode or Tank Filling mode. The Red Alarm Stop
is
raised and the system goes to Alarm Stop sequence.
When?
It takes 5 continuous minutes of the condition above for this to occur.
What
happened?
The RO or RO/EDI portion totally stops to operate. The independent
Distribution portion (AFS) allows to deliver water until tank is empty.
What to do?
Follow the action steps below and the Troubleshooting Card to solve
this dysfunction :
Step
1
2
3
4

6
Action
Connect system to Millitrack
Verify set points and values in Millitrack
Verify Feed water Conductivity. If the Feedwater
Conductivity is really a very high value then it is possible
for the Permeate Conductivity to be very high.
Verify that a SYSTEM RINSE was done (the RO
membrane is rinsed out completely). Verify that a sanitant
or cleaning chemical (ROCLEAN-A,...) is not in the RO
Housing.
Check for a closed circuit on the permeate conductivity
cell. Use a Voltmeter to check the impedance of the wires
for a closed circuit. A particle might exist between the 2
electrodes of the Conductivity. Cell causing a very
conductive circuit.
Check the O-rings on the permeate stem of the RO
membrane inside the RO Housing.

TC002 - RO Low Feed Water Pressure
Type of message : Alarm Stop
Why?
This icon is displayed when pressure measured is :
•
•
•
<0.5 bar during 1 min in Pressurization mode, or
<3.5 bar during 1 min in Tank Filling mode for systems with EDI, or
<2.5 bar during 1 min in Tank Filling mode for systems without EDI
When?
It takes 1 minute of the condition above for this to occur.
What
happened?
The microprocessor has detected a signal back from the pressure sensor
circuit which is less than the Pressure Setpoint. The measured pressure
was < the Pressure Setpoint for > 2-3 minutes. The Pressure Setpoint is
normally set to 0.5 Bar.
What to do?
Follow the action steps below and the Troubleshooting Card to solve this
dysfunction :
Step
1
2
Action
Verify possible hydraulics causes :
• Feed water off
• External or internal tubings kinked
• Progard clogged
• Cleaning port clogged
• Check RO Reject Flow
Verify possible component and/or sensor causes :
• RO Pump connected the wrong way
• Int Pressure Regulator leakage or incorrect setting
• Inlet strainer
• Inlet Solenoid Valve closed
• RO Reject and Permeate valves status and operation
• Solenoid valves wiring
• Reject and Permeate valves switched

Type of message : Alarm Stop
If an error code Er:30 (Coldfire is not responding) is displayed and before
implementing the below procedure, save the files data_persistence.bin,
nor_sdf.bin or nand_sdf.bin if available. For in-depth troubleshooting analysis,
those files will be necessary.
Why?
The Coldfire microprocessor is not responding when interrogated. This
error message can occur especially during upload.

• checking that the EDI waste stream is connected on the
back of the system
• checking that the RO cartridge is working properly (good
% rejection)
Check for a closed circuit on the Elix resistivity cell. Use a
Voltmeter to check the impedance of the wires for a closed
circuit
(see EC006/Test of the Elix Resistivity cell).

General explanation - EC000
Introduction
The section below describes how to do 2 tests that appear in almost all
troubleshooting cards:
• Test of electrical continuity,
• Verification of contact quality.
Test of
continuity
A continuity test checks if a circuit is electrically continuous thus eliminating the
possibility of an open circuit. It is useful when you want to explore a circuit
board, test connections, or make sure your soldering joints are all effective.
In this document, a continuity test is used to eliminate the possibility of a break
or open circuit in various cables and such.
Proceed as follows:
Verification of
contact
quality
Step
1
2
Action
Turn your multi-meter on.
Turn it to the continuity setting which looks like a little speaker:
3
Test it by touching the probes together and you should hear a beep.
That’s the same beep that you’ll hear if you test two connections
that are connected!
In most of the troubleshooting cards, the diagram starts with “Verify quality of
contact”.
Check the following things:
• Wires are securely inserted in the connector,
• The Molex connector pins make good contact with the PCB,
• The Molex connector is located correctly.

Diagnostic Box – EC001
Description
The diagnostic box is used by the Field Service Engineer in order to
investigate the system. The diagnostic box allows to simulate all the
sensors measurements by means of rotary switches. It is also used to
perform the system calibration with NIST resistors.
The diagnostic box allows to simulate different signals according to the
rotary switches position :
•
•
•
•
•
•
•
•
•
•
The Feed Conductivity
The Permeate Conductivity
The Elix Resistivity
The Distribution Resistivity
The Feed/Permeate Temperature
The Elix Temperature
The Distribution Temperature
The RO Pressure
The Distribution Pressure
The tank level
The different switches positions are described below :
•
•
•
•
•
Two nominal values : N1&N2
Con : This position allows to simulate the sensor by plugging a
specific resistor (NIST) directly on the diagnostic box (bottom right).
It is used mainly to calibrate the system.
Var : This position allows to simulate and modify the sensor signal
by turning the corresponding rotary switch.
OC : open circuit position
CC : closed circuit position

LCD ECO MODE
When this function is activated, the ECO mode is used to save energy
when the display is not used. It shuts down the display backlight after a 15
min period of non-use.
The ECO mode is disabled by pressing a keypad button or when a warning
message is displayed by the system (error code or warning symbol).

Diagnostic
If something is wrong with the tag reader PCBs, the MMI icons indicating
Progard/Polisher pack is out or incorrect will be displayed. This could
mean that the Pack tag has not been detected.

Test of the
RFID Reader
The pretreatment or Polisher Reader Version should be different from 0.
If the Pretreatment or Polisher Reader version is 0, then the tag reader is
defective.
Test of the
RFID Reader
with the tag
diagnostic
tool
The tag diagnostic tool (Catalog Number : ZF3000461) also used for
troubleshooting on the Integral systems allows to verify whether the tag
reader is defective.
