    NORME CE EC RULES (STANDARD EC) NORMAS DE LA CE Direttiva Bassa Tensione 2014/35/EU Low Voltage Directive Directiva de baja tensión Direttiva EMC Compatibilità Elettromagnetica EMC electromagnetic compatibility directive 2014/30/EU EMC directiva de compatibilidad electromagnética GENERAL SAFETY INFORMATION Danger! During an emergency of any kind in the room where the pump unit is installed, immediately cut off the power to the system and disconnect the instrument from the power socket! If particularly aggressive chemical materials are used, regulations on the use and storage of these substances must be strictly followed!
  • Page 3 Introduction “Centurio PRO” is a multi-measure digital instrument capable of simultaneously controlling up to 6 programmable channels for the adjustment* of pH - Redox (ORP) - Chlorine - Turbidity - Temperature - Combined Chlorine (see Chlorine feature for configuration) - Total Chlorine (see Chlorine features for configuration) - Tracers - Conductivity - Dissolved Oxygen.
  • Page 4 Connections to the main board Disconnect the instrument from the main power supply, then make the connections as shown below. For easier understanding, the board has been divided into two parts: I/O connections and Power Supply - Relay connections. See page 44 for mA connections and communication options (MODBUS).

  • Page 7 The standard settings are: Probe calibration, working mode (bleed - inhibitor - biocide). The advanced settings are: Pulse emitting water meter, flow, alarms and communication (WiFi, Mobile, ERMES). All these settings must be set for the instrument to function correctly.
  • Page 8 International. Before programming the instrument, Language, Location, Local time and date must be set (Settings/International). Since instrument activities are time-based, it is essential to set the time and date before anything else. Within the international menu, choose the language and location for the correct unit format. Units of measurement change according to local rules.
  • Page 9 Standard “Centurio PRO” settings. The standard settings are: Probe calibration and operating modes (bleed - inhibitor - biocide). To calibrate each channel, select it in the main menu. Channel availability is based on module configuration. The controller will automatically add the correct channel when a new module is installed and detected. Conductivity calibration menu.

  • Page 10: Chlorine Calibration

    CHLORINE calibration. The chlorine calibration procedure is based on the installed chlorine probe and may involve one or two calibration points depending on the probe model (see table on next page). From the main menu, select “Chlorine”, then tap “Calibration”. The installed probe will be detected automatically and, depending on the model, will be enabled for one or two calibration points.
  • Page 11 Chlorine probe table. Use the following table to check the number of calibration points for the installed probe. Note: Some probes are not supported.

  • Page 12: Tracer Calibration

    Tracer calibration. The tracer calibration procedure is based on two buffer solutions (0 BTSA and “working value” BTSA buffer solution). Depending on the probe installed, configure the model using the “Probe Tracer” menu before calibration. Note: this procedure assumes that the CONTROLLER is correctly installed, configured and connected to a functioning probe.

  • Page 13: Settable Parameters

    Channel setpoints. A setpoint configuration (for DIGITAL and PROPORTIONAL outputs) must be set for each channel (except conductivity) for the outputs to function correctly. It is also possible to set the temperature setpoint (On/Off) and assign a free output for each reading channel. Settable parameters: 1) Working Mode (digital or proportional) 2) Working range...
  • Page 14 “Cl Set-Point” (PWM) mode - Digital This mode is valid for any available “digital” output. Pulse-width modulation, or PWM, is a type of digital modulation in which information is encoded in the form of the duration in time of each pulse of a signal. The duration of each pulse can be expressed in relation to the period between two successive pulses, implying the concept of “duty cycle”.
  • Page 15 “Cl Set-Point” (Proportional) mode - Pulse This mode is valid for any available proportional/pulse output. Proportional mode makes it possible for the instrument to operate using a calculated percentage between two set values that enable or disable the Cl pump. To use this mode, tap “Proportional First Point”. PROPORTIONAL mode between 1.00Cl (0 p/m) and 0.50Cl (180 p/m).
  • Page 16 “pH Set-Point” (on/off) ALKALI mode This mode is valid for any available digital output. In On/Off mode, two values are set in the instrument that enable or disable the pH pump. To select this operating mode, highlight “Working Mode” with the cursor. Tap the screen to select.

ON/OFF mode while dosing ACID ACID SOLUTIONS dosing ON/OFF mode Set the pH value to 7.00 OFF and 7.10 ON. The instrument will enable the pH pump until the reading reaches 7.00pH. At 7.00pH the pump will be disabled until the reading goes back up to 7.10pH 7.00 7.10...
  • Page 18 “pH Set-Point” (PWM) This mode is valid for any available digital output. Pulse-width modulation, or PWM, is a type of digital modulation in which information is encoded in the form of the duration in time of each pulse of a signal. The duration of each pulse can be expressed in relation to the period between two successive pulses, implying the concept of “duty cycle”.
  • Page 19 “pH Set-Point” (Proportional) mode - Pulse This mode is valid for any available proportional/pulse output. This mode sets the instrument to operate using a calculated percentage between two set values that enable or disable the pH pump. To use this mode, tap “Proportional First Point”. PROPORTIONAL mode between 7pH (0 P/m) and 8pH (180 P/m).
  • Page 20 “ppm Set-Point” (on/off) example 1 for tracer This mode is valid for any available “digital” output. On/Off mode allows the instrument to be set to operate using two set values that enable or disable the TRACER pump. To use this mode tap “Working mode”. Example Set the ppm value to 7.00 OFF and 6.90 ON.

  • Page 33 Hypochlorous acid dissociation and relationship with pH The pH is an index of the acidity of a solution. Chemically, pH indicates the exponent in base 10 of the concentration of H+ ions present in a solution and thus the ability of the solution to accept OH- ions and neutralise them. In practice, a low pH solution is ACID, while a high pH solution is BASIC.
