    The rear of the my-Control cabinet must be accessible. • The power switch of the my-Control is located at the rear of the cabinet. Make sure that the my-Control is installed in such a way that, in case of emergency, the power switch can be easily reached! WARNING Risk of overpressure in the glass bioreactor.
  • Page 5 In most cases, the bioreactor is equipped with a Stirrer Motor that drives the stirrer shaft and impellers. The my-Control must not be switched on until the motor cables are properly connected to both the controller and the stirrer motor.

    Through a network that is connected to the my-Control (TCP/IP communication), different kind of devices can be used as a User Interface (UI). Since the my-Control is addressed by using its IP address, the User Interface is also called the Web UI.
  • Page 8 Autoclavable Bioreactor Systems 2 and 3 L Software Version mE.2.9.X; Document Version 2.9 After switching on the power of the my-Control and invoking the Web UI with the Internet browser, the my- Control displays its Home Screen. Example of the Home Screen in View mode (no user is logged in, control loops are “Idle”): The presented Synoptic View shows a glass stirred tank reactor.

    Sensor Calibration Settings Part of the LumiSens Test Data Sheet Make sure to enter the factory calibration data to the LumiSens Custom Sensor Settings at the my-Control. Basically, the LumiSens dO sensor tip is now calibrated for the rest of its lifetime.

  • Page 19: Ph Sensor Calibration Routine

    SENSOR CALIBRATION ROUTINE For more details regarding the pH sensor calibration procedure, refer to the my-Control Software Reference Manual. It is advised to calibrate the sensor with two buffer solutions (pH = 7.00 and pH = 4.00). This means that a 2 point calibration is performed.
