8 Installation  Always completely disconnect the relevant plant part before installing the instrument or connecting/disconnecting it to/from the power supply. Secure the plant against reconnection.  Only connect the instrument to the mains voltage specified on the rating plate.  Always observe technical data and ambient parameters.  Testomat 2000® PO4 requires an interference free and stable power supply. If necessary, use a mains filter to protect Testomat 2000® PO4 against interference voltages caused, e.g., by solenoid valves or large motors. Never lay connecting cables parallel to power cables. Operation � ...

9 Scope of delivery 1x Testomat 2000® PO4 1x plastic bag containing the screw caps with a hole and an insert for the screw cap of the reagent bottles 1x operating instructions Performance specifications The process photometer Testomat 2000® Phosphate is a robust wet- chemical online monitor for monitoring the phosphate content from 0 to 10 mg/l (ppm) using the photometric analysis principle. Analysis is carried out by adding two reagents and the analysis result is displayed after a reaction time of ten minutes.  Measuring range: 0 – 10 mg/l with a resolution of: - 0.1 mg/l in the range of 0 – 7 mg/l - 0.25 mg/l in the range o ...

then off again at the main switch.  In order for Testomat 2000® PO4 to operate reliably, use Heyl Testomat 2000® reagents.  Make sure that the water is not more acidic than pH 4. At lower pH values, the hose connections and other plastic parts of the device can be damaged.  If the measuring water contains more than 20 mg/I CO2 (carbonic acid), incorrect evaluations cannot be excluded.  Careful handling of the instrument increases both its operational reliability and service life! Therefore, carry out a visual inspection ...

 Install Testomat 2000® PO4 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. Information for trouble-free operation  Install Testomat 2000® PO4 vertically and without mechanical stress.  Install Testomat 2000® PO4 at a vibration-free site. Operating Testomat 2000® PO4 in the pressure range of 0.3 to 1 bar Prior to installation, please check whether lower operating pressure is required. The instrument is factory set for the operating range of 1 to 8 bar. Remove the ...

Information for trouble-free operation  The water pressure must be between 0.3 bar and 8 bar  Avoid strong pressure fluctuations  The measuring water temperature must be between 5 °C and 30 °C  For temperatures above 40 °C, the KCN type cooler should be installed in the branch line of Testomat 2000® PO4. 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® PO4. The instrument is equipped with a plug connector for plastic hoses 6/4 x 1 (external diameter 6 mm/ internal diameter 4 mm, wall thic ...

Risk of electric shocks during installation! If the power supply is not disconnected prior to installation, it may result in personal injuries, destruction of the product or damage to plant parts.  Always disconnect the relevant plant parts before installing Testomat 2000® PO4.  Only use tested cables with sufficient cross-sections for the connections. Risk of damages caused by electromagnetic fields!  If Testomat 2000® PO4 or the connecting cables are installed parallel to power cables or in close proximity to electromagnetic fields, the instrument may be damaged or measurements incorr ...

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 terminal box is now accessible.  Pierce the required rubber cable glands  with a screwdriver and insert the cable through the bush into the terminal box (1)  Subsequently pull back the cable until the bush has been turned over (2).  Connect the power supply to terminals PE, N, L or for 24 V instruments to terminals U, V.  Connect the conductor to the terminal block as shown on the ...

 Connect the plant components to the output terminals of relays 1 to 19 (e.g. valves).  If the plant components require mains voltage, connect the switched mains voltage (l) to the common contact  of the respective relay (see the connection example for 230 VAC on the left).  Connect the neutral conductor of the plant component to one of the terminals (n).  For components with a protective earth conductor connection, connect it to the PE connection.  Ensure that the leads are held securely in the terminals. No. Terminal Type Function Comment 1 2 Flush OUT External flush valve Isolated re ...

Testomat 2000® PO4 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.  Use the two fastening screws to close the upper door once installation has been completed. For more information, please refer to the section entitled "Description of the signal inputs/outputs".
