1 Safety instructions
1.1 Designated use
The analyzer is a compact photometric analytical system.
It is designed for monitoring free available or total chlorine in water.
CA71 is particularly suitable for the following applications:
• Drinking water treatment
• Monitoring wastewater outlets
• Monitoring swimming pool water
• Process water treatment
Any use other than that 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:
• Installation, commissioning, operation and maintenance of the measuring system must only be
carried out by trained technical personnel.
The technical personnel must be authorized to perform such tasks by the owner-operator.
• The electrical connection may only be established by authorized electrical technicians.
• Technical personnel must have read and understood these Operating Instructions and must
follow the instructions they contain.
• Before commissioning the entire measuring point, check that all the connections are correct.
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 defective.
• Faults at the measuring point may only be rectified by authorized and specially trained personnel.
• If faults cannot 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 directly at the
manufacturer’s or by the service organization.
1.3 Operational safety
The analyzer has been designed to state-of-the-art technology, has been tested and left the factory
in a condition in which it is safe to operate.
Relevant regulations and European standards have been met.
As the user, you are responsible for complying with the following safety regulations:
• Installation instructions
• Local prevailing standards and regulations
1.4 Return
If the analyzer requires repair, please send it cleaned to your sales center.
Please use the original packaging when returning the device.
Please enclose the completed "Declaration of Contamination and Cleaning" form (copy the second
last page of these Operating Instructions) with the packaging and also the shipping documents. The
unit cannot be repaired if this declaration is not duly completed!

!Note!
For the reagents, you need an additional base at max. 35 cm (13.8 inch) under the pumps in the
open version. The dimensions of the reagent bottles are as follows: 90 x 90 x 215 mm (3.54 x 3.54
x 8.46 inch). Depending on the version, the number of bottles varies between 2 and 5.
Furthermore, in these versions the outlet pipe has to be installed to the right beside the analyzer.
Please refer to the sheet enclosed with the Operating Instructions.
The outlet pipe must be secured to a wall in such a way that the incline of the outlet pipes from the
photometer is between 5 and 10 % . You must extend the outlet pipes where necessary.
3.3.2 Connecting the sample line
One-channel version
Two-channel version
• One or two collecting vessels (with or without level monitoring) form part of the scope of delivery,
depending on the version.
• In the two-channel version, level monitoring is only possible for one channel.
• One collecting vessel can be mounted on the housing. A second vessel would have to be made
available near the device.

Adjusting the level monitoring
You have to adjust conductive level monitoring depending on whether you want to connect one,
two or three analyzers to this single collecting vessel.
1. Depending on the application, mount the right adjusting pin (→å8, →å9, item 2) or do
not use any adjusting pin.
2. Pull the marked pipe (item 3) downwards in accordance with your application (1, 2 or 3
analyzers) to set an optimum collecting volume.
3.4 Installation instructions
To install the analyzer at the intended location, proceed as follows:
1. Mount the analyzer and secure it to a wall using screws (Ø6 mm / 0.24").
For the installation dimensions, please see the previous chapter.
2. Using a spirit level, check that the cabinet is hanging or standing straight. Only in this way can
any air bubbles present escape from the cell.
3. Fit the edge covers (with GFR housing only).
4. Lay the drain pipe for the reaction products. Where possible, use solid pipes (PVC or PE,
internal diameter 1" with 3% incline).
5. Insert the valve hoses accordingly. These were partly removed from the valves for
transportation. This prevents the hoses from sticking or pressure being applied to a point in the
hose over an extended period.

6. Secure the hose boxes in the appropriate pump holders (→å12):
Sample pump left, reagent pump right. The direction of flow of the sample and reagent must
be counterclockwise.
7. Connect the sample supply.
!Note!
The sample can be obtained as follows:
– Directly or via a reversible flow filter or a cross-flow filter by means of a small pump (rating
approx. 300 ml/min), suitable for clear media, e.g. in the outlet of a sewage treatment plant
– From microfiltration; this is practical for media containing flocculants, e.g. in an activated
sludge basin
– Sample conditioning using ultrafiltration for contaminated media, e.g. from the primary
settling tank.
For questions regarding sample conditioning and its automation, please contact Service or the
sales center responsible for your region.
8. Connect the tubes from canisters containing reagents, standards and cleaning agents to the
following nozzles:

3.5.1 CAT 430 or ultrafiltration provided by customer and two CA 71
units
3.5.2 CAT 411, CAT 430 and two CA 71 units (two-channel version)
3.6 Post-installation check
• After installation, check that all connections are secure and leaktight.
• Ensure that the hoses cannot be removed without effort.
• Check all hoses for damage.
• Permeate can contain air bubbles (CAT430)
or is free of bubbles (ultrafiltration provided by
customer)
• Distance between the analyzers as short as
possible: sample line between T-section and
second analyzer (, →å13, item 2) shorter
than 1.5 m
• Cross-section of sample line ID 3.2 - 4 mm
• Only one collecting vessel required
!Note!
Make sure sufficient sample is always available
for both analyzers. Bear this in mind when
selecting maintenance intervals for CAT430 and
when setting the buffer volume at the collecting
vessel.

4.1 Electrical connection
#Warning!
• The electrical connection may only be established by an electrical technician.
• The electrical technician must have read and understood these Operating Instructions and must
follow the instructions they contain.
•Before beginning the connection work, ensure that no voltage is applied to the cables.
4.1.1 Quick wiring guide
"Caution!
• You have to fold out the frame of the analyzer to reach the terminal block.
• Beforehand, release the hoses from the outlet pipe. Otherwise there is a danger of flooding.
• Connect the hoses again after folding the frame back in.
Fold out the frame as follows:
1. Release the two bottom Allen screws (AF 6) by 3-4 rotations (→å15, item 1).
2. Unscrew the two upper Allen screws completely so that the frame folds out. In this way, you
reach the terminal block (item 2).

!Note!
• Alarm values 1 and 2 do not need to be connected if the process control system sets its own alarm
values at the analog output.
• When using a sample conditioning system: connect terminals 57 and 53 on CA 71 to the
corresponding terminals of the sample conditioning system. For the allocation of these terminals,
please see the Operating Instructions of the sample conditioning system.
• 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 connections
4.2.1 Shielding of the analog outputs
The interference suppressor dampens interference from electromagnetic effects on control, power
and signal lines.
After connecting the data transfer cables, clip the interference suppressor (in scope of delivery) onto
the cable cores (not onto the outer insulation of the cable!). You have to route the cable screen
outside around the interference suppressor and connect it to PE (brass screw with bolt) at the top
right in the connection compartment (→å18).
!Note!
With the two-channel version (data cables at analog output 1 and analog output 2), route the cable
cores of the two data cables through the interference suppressor.
