Installation instructions

To install the analyzer at the intended location, proceed as follows:

1.

Mount the analyzer and secure it to a vibration-free wall using screws (Ø6 mm / 0.24"). The fastening clips on the housing make sure that the necessary distance to the wall is observed for ventilation purposes.

For the installation dimensions, please see the previous chapter.

2.

Using a spirit level, check that the cabinet is hanging straight. Only in this way can any air bubbles present escape from the cell.

3.

Fit the edge covers (with GFR housing only).

Endress+Hauser

Stamolys CA71SI Installation

4.

Lay the drain pipe for the reaction products. Where possible, use solid pipes (PE, internal diameter 1" with 3% incline).

5.

Screw the screw-in connector ID 16 into the outlet pipe from below. Secure the Grifflex hose

ID 19 to the nozzle with a hose clip (only CA71SI-A).

6.

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.

NOTICE

Terms for special terminals

► Limit switches 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 analyzer to the corresponding terminals on the sample conditioning system. For the allocation of these terminals 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.

► All external relay contacts have to be connected to 230 V.

Post-connection check

Carry out the following checks after electrical connection:

Device status and specifications

Is the analyser or cable externally undamaged?

Note

Visual inspection

Electrical connection

Does the supply voltage correspond to the data on the nameplate?

Note

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 separately 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

Current output simulation:

1.

Hold both arrow keys down (see "Display and operating elements" chapter) and connect the analyser 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: a. Check the terminal assignment for analogue output 1 or 2.

b. Disconnect the analogue outputs from your PLC, PLS or your data logger and repeat steps

14 with the restriction that you measure the current values at the terminals of the analyser and not at the PLC, SPL or data logger.

If these current values are correct, please check your PLC, SPL, the data logger or the electrical cables.

The setting displays the parameter that is being measured.

This is defined by the product specification and set in this menu item at the factory. Do not change the value.

Otherwise, you will receive an "Incorrect photometer" error message.

If "yes" is selected, all the settings are reset to the factory settings.

You must set the current date and time (scroll through the menu, third-last point).

In the event of a reset, the date for the 1st calibration and the 1st flush is set to the following day.

The measuring unit selected depends on the type of photometer. This setting also affects the scope of the measuring range.

The calibration factor is the ratio of the measured concentration of the calibration standard to the predefined concentration of the standard (see

"PARAMETER ENTRY", calibration solution). The deviation results from factors such as reagent aging, aging of constructive components, etc.

The calibration factor compensates for these effects. CA

71 checks the registered calibration factor logically. If the factor is outside of the error tolerance, the calibration is automatically repeated. If the value is still outside the tolerance range after repeating calibration, an error message appears and the analyzer continues to work with the most recently registered, logically correct factor.

The last 100 calibration factors are stored in the memory with the date and time and can be retrieved by pressing the

J

key.

The calibration factor can be changed manually.

Optional dilution modules are taken into consideration in the calibration factor.

The offset gives users the option of adapting to an external comparison measurement.

(Change the sign with the

J

key.)

If the sample is diluted externally between taking the sample and the analyzer, the dilution factor has to be entered here.

If an optional dilution module is used, the factor remains

1. The dilution is taken into consideration by means of the calibration factor.

Dosing time for sample or standard. During this time, the entire system is flushed with sample or standard, so when the reagent is added there is definitely only fresh sample in the mixer. If sufficient sample is available, or in the event of an external collecting vessel with a long supply line, select the highest possible value.

Dry commissioning

When the analyzer has been configured and calibrated, the measuring cycle starts automatically.

Configuration is no longer necessary.

To perform initial commissioning or to readjust the device parameters, proceed as follows:

1.

Plug in the analyzer's plug with grounding contact into the socket.

2.

Press the

H

key until AUTO MEASURING is displayed.

• If possible, let the analyzer warm up in standby mode before commissioning ("Auto measuring" display). The time can be defined via the "1. measurement" option in the PARAMETER ENTRY menu.

• At the start of measurement with a cold analyzer, the first measuring results will be incorrect. The reaction is temperature-dependent and if the temperature is too low the predefined reaction time is insufficient for a complete reaction. For this reason, never carry out calibration with a cold analyzer. Wait at least two hours before carrying out calibration.

3.

Select the CONFIGURATION menu and configure up to and including "Current date/time".

With

H

you can return to the main menu.

Then switch P1 "off".

8.

Now proceed as with dry commissioning (from step 2).

6.2.3

Using a dilution module

You can extend the measuring range of your analyzer with the sample dilution module.

How it works:

• The analyzer determines the absorption of the sample at the specified wavelength.

It does not matter whether the sample was diluted previously or not.

• The characteristic of the photometer (--> standard calibration data) refers to the concentrations of the diluted sample and not to those of the (undiluted) original sample.

• The dilution factor is not taken into account until the measured value is calculated.

• The concentration information you specify for the measuring range and the alarm values in

PARAMETER ENTRY refer to the concentrations of the original sample.

You achieve maximum measuring accuracy if you also dilute the standard with the dilution module.

In the event of a 1:10 dilution, you have to use a 10 mg/l standard solution instead of a 1.0 mg/ l standard solution (without a dilution module) for example.

Balance changes to the dilution ratio (e.g. through hose aging) with the calibration. The calibration factor determined takes into account all deviations from the ideal state through reagents, the photometer and dilution.

Installing the dilution module

The dilution module is supplied ready to use.

Installation:

1.

Release the sample pump hose from the hose connector to valve 1 (

→ å 17, item 4).

2.

Connect the sample hose of the dilution module (black/black or yellow/blue, depending on the version) to the hose connector that is now free.

3.

Connect the T-section (item 1) of the dilution module to the input of the sample pump (hose box K1). Use the original sample pump hose for this purpose.

4.

Fit the dilution module onto the free hose box positions of the sample pump.

5.

Connect an outflow hose (O) to the free outlet of the T-piece (item 1).

Route this hose in the device in such a way that is guided at least 20 cm upwards and then into the open outlet. This prevents the hose from running dry.

NOTICE

Measuring errors due to malfunctioning outflow from photometer

Backwater, siphon effects or similar influence the sample outflow and cause measuring errors

► Do not connect the outflow hoses of the dilution module and the photometer.

Replacing reagents

!

CAUTION

Corrosive chemicals and other risks

Eye or skin injuries or crushes possible

► There is a danger of crushing limbs at doors, inserts and pump heads.

► Refer to the warning instructions in the safety data sheets when handling reagents or cleaning solutions. Wear protective clothing, gloves and goggles.

► If reagents come into contact with the skin or eyes, carefully rinse with copious amounts of water and consult a physician immediately.

► Never add water to reagents. Reagents containing acids may splash and heat may build up.

If you store the reagents correctly (in the dark, not over 20 ˚C) they will be stable for minimum

12 weeks from the date of manufacture (batch number). When this period of time has expired, the reagents must be replaced. Shelf life can be prolonged by keeping the reagents in a dark, cool storage place. The reagents absolutely must be replaced when:

• The reagents have been contaminated by sample (see "Trouble-shooting instructions")

• The reagents are too old

• The reagents have been spoilt by incorrect storage conditions or environmental influences.

7.2.1

Checking reagents

1.

Check the concentration of the standard in the laboratory. Adapt the values (PARAMETER

ENTRY, calibration solution") or replace the standard solution.

2.

Mix 10 ml of standard (c=500 μg/l or higher) and 5 ml of reagent SI 1 in a beaker.

3.

After approx. 5 minutes, add 5 ml each of reagent SI 2 and SI 3.

The finished mixture must be free of particles.

The reagents must be replaced if no visual coloration (blue) occurs after max. 2 minutes or if the mixture is not free of particles.

7.2.2

Replacing reagents

1.

Carefully remove the hoses from the canisters and wipe them with a clean and dry (paper) towel. Wear protective gloves when doing this.

2.

Switch on the reagent pump for about 5 seconds for the hoses to be drained.

3.

Replace the reagent canisters and feed the hoses into the new canisters.

4.

7.3

Replacing pump hoses

!

CAUTION

Risk of splashing reagents when removing hoses from the hose nozzles

► Wear protective clothing, gloves and goggles.

The peristaltic pumps used for the analyzer convey the medium in a combination of vacuum and displacement pump. The pump rate is dependent on the elasticity of the pump hoses. Elasticity decreases and the pump rate drops as mechanical stress increases. Wear depends on mechanical stress (measuring interval, pump pressure). The wear effect can be compensated by periodical calibration. If the hose elasticity becomes too low and the pump rate is no longer reproducible, it is necessary to replace the hoses.

Removing the old hoses

1.

Remove the reagent hoses from the reagent canisters in order to prevent contamination of the reagents.

2.

Flush the old hoses with ultrapure water first and then with air to empty them (see SERVICE).

3.

Remove the hoses from the nipples of the hose boxes (item 5).

4.

Release the hose box(es) (1 to 3 per pump):

– Press against the lower retainer (item 3).

– You can now remove the hose box along with the pump hose.

– Remove the old hose from the box any dispose of it.

– Clean the hose box and the roller head (item 1) with a tissue.
