Download the safety data sheets for the supplied reagents at http://www.heylanalysis.de . Intended use The process photometer Testomat 2000 ® CLO2 is a robust wet- chemical online monitor for monitoring the chlorine dioxide content from 0 to 4.7 mg/l (ppm) using the colorimetric analysis principle. The feed water must be clear, colourless and free of undissolved particles.
Further documents Testomat 2000 ® CLO2 is a plant component. Therefore, always observe the maintenance manual of Testomat 2000 ® / Testomat and the documentation of the plant manufacturer. ®...
Always observe technical data and ambient parameters. Testomat 2000 CLO2 requires an interference free and stable ® power supply. If necessary, use a mains filter to protect Testomat NOTE 2000 ® CLO2 against interference voltages caused, e.g., by solenoid valves or large motors.

Application instructions Application instructions Wait at least 5 seconds before switching the instrument on and then off again at the main switch. In order for Testomat 2000 CLO2 to operate reliably, use Heyl ® Testomat 2000 ® indicators.
Installation Installation Risks resulting from incorrect installation! WARNING Install Testomat 2000 ® CLO2 at a location where it is protected against dripping or splash water, dust and aggressive substances – e.g. in a switch cabinet or on a suitable wall.
® Water inlet The measuring water is taken from the main water line of the water treatment plant and fed to the inlet connection of Testomat 2000 ® The instrument is equipped with a plug connector for plastic hoses 6/4 x 1 (external diameter 6 mm/ internal diameter 4 mm, wall thickness 1 mm) as standard.
® Only use tested cables with sufficient cross-sections for the connections. Risk of damages caused by electromagnetic fields! If Testomat 2000 ® or the connecting cables are installed parallel to NOTE power cables or in close proximity to electromagnetic fields, the instrument may be damaged or measurements incorrect.
Installation Connecting the mains voltage Only connect the instrument to the specified mains voltage. Refer to the rating plate for the appropriate mains voltage. Connect the cables as follows: Loosen both fastening screws and open the upper door. The ...

Installation Connecting the inputs and outputs Testomat 2000 ® CLO2 has the following connections for control and monitoring functions. Do not connect an external voltage to these connections! Ensure that the leads are held securely in the terminals.
Commissioning Commissioning Adhere to the respective safety data sheet! CAUTION Trouble-free operation of Testomat 2000 ® CLO2 is only guaranteed when using Heyl Testomat 2000 ® indicators! Ensure that the reagent bottles are connected as shown in the figure above.
® Switching Testomat 2000 on/off (1) Mains switch Use this switch to switch the instrument on or off. (2) Instrument fuse (inside the instrument) This fuse protects Testomat 2000 ® and the outputs against overloads and short circuits.

Password protection and basic program Minimum interval = 1 litre, maximum interval = 9999 litres. The Volume controlled analysis is carried out once the programmed water quantity has been measured. The line and the measuring chamber are flushed prior to Start via water meter the analysis (observe the programmed flush times).
Password protection and basic Typical analysis cycle Analysis interval Sequence of 1. Flush the measuring chamber and line times 2. Fill the measuring chamber 3. Check the sample water for soiling The stirring mechanism is switched on Dose the reagents 12x reagent A, 5x reagent B Allow a reaction time of one minute 4.
If very short analysis intervals are required, or if a very long (several metres) sampling line or a line with a large diameter is used, an external flush valve should be installed upstream of Testomat 2000 ® The external flush valve has to be connected to the "Flush” outlet. If the unit is used for monitoring two measuring points, external flushing prevents incorrect measurements caused by sample mixing.
Entering further basic program Interval pause If the analysis is triggered via a timer, the interval between two analyses (plus flushing time) is determined by the interval pause. The shortest interval can be 0 minutes. In this case, analyses are carried out continuously.
Entering further basic program data Hysteresis The respective limit value output only switches after the first, second Suppression of or third bad analysis (suppression of the first or the second measured bad analyses value). This increases the reliability of the analysis evaluation, e.g. after the measuring point has been switched over or if the sampling line has not been flushed sufficiently.
Entering further basic program Switch functions of the limit value outputs LV1 and LV2 Switch function 0, duration Schematic representation of switch functions If the limit value LV1 or LV2 has been exceeded, the output relay LV1 or LV2 reacts. If the measured value falls below the limit value LV1 or LV2, the relevant relay drops out again.
