1. General
Before mounting the M 1031 C analyser you must read the instructions. Anauthorized person must carry out mounting of the analyser.Type M 1031 C analyser is a measuring instrument operating on the basis of the
amperometric method. It is used for measuring free chlorine concentration in water invarious dosing fields such as:
Drinking water
Pool water
Treatment of industrial and sewage water
The analyser is always purchased together with all accompanying elements that arenecessary for quick and functional installation of the measuring system (armature ofthe sink, installation inserted pieces, screws, ball tap, drilling templates)
The analyser has been designed for continuous operation.

2. Basic principles of the ampere-metric chlorine measurement
2.1Diagram showing level of HOCL acid depending on PH and temperature
General:
Currently there are two methods for determining/measuring chlorine in use:Chlorometric determiningElectronic measuring (amperometrics)
Chlorometric determining is mainly used for checking and calibration.DPD method is still used in public swimming pools(reagent: N,n-dietil-p-fenildiamin).Chlorometric determining is not appropriate for continuous checking and automaticchlorination. Measuring is in such cases executed via electronic measuring, with theamperometric method, with the measuring cell for chlorine and the appropriatemeasuring and regulating instrument. We need to differentiate between free andcombined chlorine.The term total chlorine is usually related to the chlorine in water, consisting of the
elemental chlorine Cl2, hypochloric acid (HOCl), hypochloric ion (ClO), and of acombination of the above. With short reaction periods these forms of chlorine arecapable of destroying bacteria, viruses and oxidising organic substances.The term combined chlorine is usually related to the chlorine in water, which ischained to chlorine compounds with ammoniac (NH3) or ammoniac ion (NH4+). Theterm total chlorine means free and combined chlorine together. Free chlorine ismeasured via amperometric measuring. The result of hypochloric acid (HOCl) is thedisinfection of water. This acid is split into hypochloric ion (ClO) and hydrogen ion(H+), depending on the PH value of the water.The diagram below clearly shows that the share of hypochloric acid decreases when
the PH value increases. E.g., at PH value 9 the share of hypochloric acid drops toapprox. 3 %, as compared to 97 % at PH 6.

3. Mounting
3.1Determining the optimal place of installationMount the analyser as close as possible to the place of taking water sample and in
an easily accessible place in order to make the mounting undisturbed.
The outlet connection of the armature of the analyser sink must always be higherthan the main drainage outlet (the outlet tap should never rise above the height of thearmature of the analyser sink).
NELA0006
3.2 Drilling holes in the wall
Place the enclosed template (code SABXXXXX) for drilling holes against the wall(pay attention to the first angle). With help of the template drill 3 holes with adiameter d8 and depth 60 mm into the wall. Insert the enclosed PVC wall plugs d8into the holes.Insert three enclosed screws with the length of 70 mm into the wall plugs and leaveapprox. 12 mm of the screw unfastened (unturned).
3.3 Placing
Hang the analyser on the three screws and check the stability of the installation.
4. The level of free-running sample water
4.1 Pools
The minimal level of free-running sample water is: 1 m of the water column above thelevel of the analyser.
When the minimal level of free-running sample water is not possible, take the samplewith the help of a pump.
4.2 Water supplies
When you are taking the water sample, of which the pressure exceeds 6 bars, inserta reducing valve and set it to 1 bar.

6. Connecting the inlet and outlet pipes of sample water
Before connecting the analyser, you must wash out the inlet pipes.Connect the inlet pipe d10/d8 of the sample water to the inlet connector of theanalyser.The regulating valve serves as a regulating element (setting of water flow through theanalyser).Install an outlet pipe with a diameter of d20 mm on the outlet end of the outletarmature.The sample water flow through the analyser is set by means of the regulating valve.Sample water flow through both outlet pipes of the analyser must be even. Thesample water usage is 0.7 l per minute.
7. Connecting to power supply
Connect the M1031C analyser to a voltage of 24 VAC (+/- 10%), 50 - 60 Hz. Connectthe voltage through the 5-pole connector on ECP00266 cable to the connector on theinstrument (CONNECTION).All such connectors have a code indicator and can therefore only be connected ifturned the right way. The connectors on the cable are to be gently and correctly puton the connectors on the instrument and the fixing nut is to be gently turned.

All CAN communication units (PLC control units, sensors, valves) in SELECANversions of communication must have parallel wiring. The maximum number of CANcommunication units connected in this way must not exceed 64.CAN network consists of three signals: CAN H (CAN +), CAN L (CAN -) and CANGND.
10.2 Segmental circuit (RECOMMENDED!)
The most recommended wiring is shown in the drawing below. The maincommunication line is divided into segments. CAN communication units A - I (PLCcontrol units, sensors, valves) are connected via CAN distributors 1 - 6.Terminators (T), which are connected to CAN H (CAN +) and CAN L (CAN -), mustbe placed at the beginning and at the end.

The main CAN network is divided into more segmental networks. When dividing themain CAN network into segmental networks, you must pay attention to the length ofthe segment; the length of the segment depends on data flow velocity. One segmentis marked in the picture above and in the tables on the following page total cablelength can be determined. The tables are stated for cables with 5 ns/m and 10 ns/mtime delay.
It is evident from the table below that when using a cable with 5ns/m time delay anddata flow velocity of 20Kbit/s, the total segment length can be up to 150 m; the lengthof the cable made of all in this way connected segments must not exceed 750 m.
The length of the cable, which is used to connect CAN distributors 1 and 2 and allCAN communication units plugged to CAN distributor 2 (PLC control units, sensors,valves), is considered the total segment length.

You need the MXXX charcoal filter for this procedure. Unscrew the sample input atthe M1031C analyser and connect it through the MXXX charcoal filter. Pay attentionto the proper flow direction of the sample water running through the beforementioned filter. We need some additional pressure at the beginning, to keep thesample water running through the MXXX charcoal filter (the flow through the M1031Canalyser should be even). Keep the sample running through the MXXX charcoal filterfor at least ten minutes. The measured value should not exceed 0.05 mgCl2/l. In casethe value exceeds 0.05 mgCl2/l, clean the charcoal filter as well as the input filter onthe M1031C analyser.In case that the value is still above 0.05 mgCl2/l, please, consult with the authorisedservice of the CONTROLMATIK ABW.
15.3 Setting the value:
Before calibrating for the first time, we must keep the M1031C analyser running for atleast 24 hours. Because of the various water structures, the analyser works properlyonly when the measuring cell has oxidised correctly. Then we can set the analyserand keep it running for a week and then we calibrate it again. Keep the set analyserrunning and calibrate after a week. Always repeat the procedure after the measuringcell has been serviced and in case the M1031C analyser has not been running formore than a week.When you are calibrating the analyser this time, we recommend that you take notesof the values at specific levels. The data will be of great help when you are calibratingthe M1031C analyser later on.
