  • Page 4: General Description

    Product description 1. GENERAL DESCRIPTION Red is a high-precision pH controller that at the same time is simple to install and operate. Specially designed for in-line or in-tank regulating processes, where pH adjustment with acid or with base is needed, and for neutralisation processes using acid and base. The controller has two analogue (4-20 mA) and digital (relay) control outputs for acid and/or base dosing pumps.

  • Page 7: Setpoint Configuration

    Configuration 4.2 Setpoint configuration Setting the desired values for pH for the two control channels by reference values or setpoints for alarm. To enter the setpoint: 07.00 change the value with the up/down CONTROL arrows and confirm with ENT ALARM REGISTER 4.3 Calibration Calibration of the sensors used for pH and flow rate.

  • Page 8: Control Configuration

    Configuration - K (l/p): This type of flow meter requires entry of the configuration value the manufacturer indicates in litres/pulse. - Time Q=0: In these flow meters, which calculate the flow rate from the time between two consecutive pulses, a wait time from which the flow rate is considered to be zero needs to be defined.

  • Page 9: Advanced Control Configuration. Piq Control

    Configuration which the output will be ON for the proportional part of the time corresponding to the regulating output. Salida al 100% Salida al 25% 5’ 5’ 10’ 10’ - Limit out: If a 4-20 mA output is used, this parameter allows you to limit the output value so as to limit the maximum dosing pump flow rate.
  • Page 10 Configuration Example: For a flow rate of 200,000 l/h of water and a PpH = 1, proportional dosing of acid will be: (1 / 100,000) x 200,000 l/h = 2 l/h The proportion needed to achieve a specific pH will depend not only on its nature and concentration, but also on the nature of the water to be treated and the rest of the dosed products that can influence this parameter.

  • Page 11: Alarms

    Configuration Bear in mind that if there are any filters between the injection point and the sensor, the calculation of 10 metres x 1 m/s = 10 seconds will no longer be valid. 4.5 Alarms 4.5.1 pH alarms To set the alarms, enter the upper and lower tolerance values with respect to the value entered as the setpoint and the time from which, with the reading outside tolerance range, the alarm must be activated.

    Configuration Q ALARM DET 0.20 % Q = 0 200 s CONTROL ALARM Reset: N ALARM DETECTOR Stop: None REGISTER Reset: enables automatic alarm reset when the reading is back within the permissible values. Stop: enables the dosing control outputs to be shut down. 4.6 Configuration of the register outputs If any of the 4-20 mA analogue control outputs is unused, these can be used to be configured as outputs for logging any sensor readings.

  • Page 13: Communications Settings

    Configuration - Units: Enables selection of the working units for the flow rate (litres or gallons) and temperature (Celsius or Fahrenheit) - pH Control: Enables selection of whether the pH control is performed with an acid or a base and, in case of neutralisation, enables specification of which channel the acid and base are on - Temp.
