1.1 Designated use
With 18% silicon is the second most frequent element of the earth crust. It occurs
chemically bonded as silicate or silicon dioxide in a variety of minerals. From these
minerals silicate or silicic acid is washed out in low quantities to waters.
There are no standard limits for drinking water since silicate is not known to be harmful
to health.
But in boiler feed water and boiler water, there may be only low silicate concentrations.
Under thermal charge or under high pressure insoluble silicon dioxide is formed. It
solidifies in boilers, heat exchangers and turbine blades and thus reduces the heat
exchanger’s efficiency or causes overheating.
The standard limit for boiler feed water is 0.02 ppm silicic acid (SiO2). For injection and
boiler water the standard limits are pressure dependent. For example, at an operational
pressure of 68 bar (986 psi), the concentration of silicic acid in boiler water must not
exceed 10 ppm.
The analyzer is a compact photometric analysis system.
It is designed for the almost continuous monitoring of the silicate content in ultrapure
water and boiler feed water.
In particular, the analyzer is intended for:
•steam and condensate analysis
•reversed osmosis
•demineralisers.
Any other use than the one described here compromises the safety of persons and the
entire measuring system and is, therefore, not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
1.2 Installation, commissioning and operation
Please note the following items:
•Installation, electrical connection, commissioning, operation and maintenance of the
measuring system must only be carried out by trained technical personnel.
The technical personnel must be authorised for the specified activities by the system
operator.
•Technical personnel must have read and understood these Operating Instructions
and must adhere to them.
•Before commissioning the entire measuring point, check all the connections for
correctness. Ensure that electrical cables and hose connections are not damaged.
•Do not operate damaged products and secure them against unintentional
commissioning. Mark the damaged product as being defective.
•Measuring point faults may only be rectified by authorised and specially trained
personnel.
•If faults can not be rectified, the products must be taken out of service and secured
against unintentional commissioning.
•Repairs not described in these Operating Instructions may only be carried out at the
manufacturer’s or by the Endress+Hauser service organisation.

•Level measurement is only for one channel possible.
•Only one collecting vessel can be mounted at housing. The second is to be placed
nearby the analyzer.
Adjusting the level measurement (one-channel version only)
Adjust the conductive level measurement due to the number of connected analyzers.
1. In dependence of the application, mount the right adjusting pin or no adjusting pin
(Fig. 6 and Fig. 7, position 2).
2. Pull the marked pipe (position 3) downwards due to your application (1, 2 or 3

3.3 Installation instructions
To install the analyzer at the intended location, proceed as follows:
1. Place the analyzer in position and secure it to a wall using M6 screws, if necessary.
For the installation dimensions, please see previous chapter.
2. Use a spirit level to check that the cabinet is standing or hanging level. This is the
only way to ensure that any air bubbles that occur can escape from the cell.
3. Place the edge covers on the analyzer edges (with GFK housing only).
4. Lay the drain pipe for the reaction products. Where possible, use fixed pipes (PVC
or PE, internal diameter ¾ " with 3% incline).
5. Insert the valve hoses according to Fig. 9. This prevents the hoses becoming stuck
or being pressed against the same position for a long period of time.

4 Hose valve 2, back, cleaning agent
5 Hose valve 1, front, sample
6. Secure the hose cassettes in the pump brackets:
Sample pump on the left, reagent pump on the right. Here, the flow direction of
sample and reagent must be anticlockwise.
7. Connect the sample transfer.
!
Note!
The sample can be obtained as follows:
– Directly or after a reversible flow filter or a cross current filter by means of a small
pump (rating approx. 300 ml/min), suitable for clear media, e.g. in the discharge
channel of a sewage treatment plant
– From a sedimentation tank or after microfiltration; this is practical for media
containing flocculants,
e.g. in an activated sludge basin
– Sample conditioning using ultrafiltration for heavily soiled media,
e.g. from the primary settling tank
For questions regarding sample conditioning and its automation, please contact
Endress+Hauser Service or the
Endress+Hauser Sales Centre responsible for your region.

8. Connect the tubes from canisters containing reagents, standard and cleaning
agents to the following nozzles:
!
Note!
The pressure of the hose cassette is set at the factory such that the sample and reagent
are fed in without bubbles.
Only change the pressure if the factory setting does not meet your requirements. The
setting is changed by turning the adjustment screw using a 2.5 mm Allen key.

Note!
•Alarm values 1 and 2 do not need to be connected if the PLC sets its own alarm values
at the analog output.
•When using a sample conditioning system:
Connect terminals 57 and 53 on the CA 71 to the corresponding terminals on the
sample conditioning system. For the allocation of these terminals, please see the
sample conditioning system operating instructions.
•If there is a 24 V voltage at terminal 57, the analyzer will not begin measurement
(sample not ready). To start measurement, the voltage must stay at 0 V for at least
5 seconds.

4.2 Signal connection
4.2.1 Screening of the analog outputs
The interference suppressor attenuates electromagnetic effects on control, power and
signal lines.
After the connection of the data transfer cables clip the interference suppressor (in
scope of delivery) on the cable cores (not on the outer insulation of the cable!). Place
the cable screen out of the interference suppressor and connect it to PE (brass screw
with bolt, top right in the connection compartment) (→Fig. 13).
!
Note!
With the two-channel version, place the cable cores of all cables (data cables to analog
output 1 and to analog output 2) through the interference suppressor.

Two-channel version
!
Note!
Condition fulfilled means:
•AV 1: concentration > Alarm value 1
•AV 2: concentration > Alarm value 2
•Fault: error occurred
Contacts AV 1, AV 2 and fault are only affected during automatic operation.
4.4 Serial interface
Terminal assignment:
The results (measured value+unit of measure+CR) are output in the "Data memory
Measured values" menu.
The calibration results (measured value+unit of measure+CR) are output in the "Data
memory-Calibration factors" menu.
!
Note!
•A null modem cable is required (not a crossed one).
•The analyzer does not have to be configured for the interface.
The following commands can be sent from the PC, in order to read out data:
•"D" = Data memory-Measured values
•"C" = Data memory-Calibration factors
•"S" = Setup (parameter entry, configuration...)
•"F" = Frequency (current)

4.5 Post-connection check
Carry out the following checks after electrical connection:
Current output simulation:
1. Hold both arrow keys down (see "Display and operating elements" chapter) and
connect the analyzer to the mains or switch the mains switch on (if available). Wait
until the display "0 mA" appears.
2. Check on your PLC, PCS or you data logger whether the current value is the same.
3. Press the
F
key. Browse to the next current values (4, 12, 20 mA, depending on
the setting).
4. Check that the respective current values are also on your PLC, PCS or your data
logger.
5. If the values are not there, check the terminal assignment for analogue output
1 or 2.
Device status and specifications Note
Is the analyzer or cable externally undamaged? Visual inspection
Electrical connection Note
Does the supply voltage correspond to the data on the nameplate? 230 V AC / 50 Hz 115 V AC / 60 Hz
Are current outputs screened and connected?
Are the mounted cables relieved of tension?
Cable type properly disconnected? Guide power supply and signal lines
separate over the entire travel
distance. Separate cable channels
are ideal.
Cable routing without scuffing or cross-overs?
Are power supply and signal lines connected correctly according
to wiring diagram?
Are all screw terminals tightened?
Are all cable entries mounted, tightened and leak-resistant?
Interference suppressor at the analogue output?
Current output simulation See procedure below

5.1 Operation and commissioning
The following chapters provide you with information on the analyzer’s operating
elements and explain how to make settings.
In chapter “Commissioning” you will find the procedure for initial start-up and for daily
analyzer operation.
