  • Page 5: Health And Safety Information

    Devices that radiate strong electromagnetic waves can influence the measurement data or result in a malfunction of the sen- sor. Avoid using the following devices in the same room as the TriOS sensor: mobile phones, cordless phones, transmitters/ receivers and other electrical devices that produce electromagnetic waves.

  • Page 6: Warnings

    Devices from TriOS Mess- und Datentechnik GmbH meet the highest safety standards. Repairs to the device (which involve the replacement of the connecting cable) must be carried out by TriOS Mess- und Datentechnik GmbH or by a workshop authorized by TriOS. Defective, improper repairs can lead to accidents and injuries.

  • Page 10: Commissioning

    Commissioning Chlorine Dioxide 3 Commissioning This chapter deals with the commissioning of the chlorine dioxide sensor. Please pay particular attention to this section and follow the safety precautions to protect the sensor from damage and yourself from injury. Prior to electrical installation (chap - ter 3.2) of the sensor, it must first be filled with gel electrolyte as described in chapter 3.1.
  • Page 11 Commissioning Chlorine Dioxide Place the membrane cap on a clean surface and fill to the rim with gel electrolyte. Place the G-holder on a clean surface with the fabric facing down and moisten the G-holder with gel electrolyte. Use the tweezers [1] to grasp the G-holder [2] with the fabric facing down and place the G-holder centrally on the memb - rane in the membrane cap [3].

  • Page 12: Electrical Installation

    8. Power (9...30 VDC) Insert the connector into one of the supplied TriOS cables. Connect the male end of the cable into the connector on the sensor by making the pins align with the slots of the cable. The next step is to turn the locking sleeve clockwise to secure the end of the connector.

    The sensor must be used for measurements in the flow cell type FLC (see chapter 4). The use of the sensor in other flow cells must be approved by TriOS GmbH. Otherwise, no warranty will be given for the proper functioning of the sensor or for resulting damage to property or personal injury.

  • Page 14: Use

    Chlorine Dioxide 4 Use The chlorine dioxide sensor can be operated with all TriOS controllers. Instructions for correct installation can be found in the relevant controller manual. A bypass installation of the sensor is essential for correct results. Therefore we strongly recommend to use the sensor in the flow cell type FLC for permanent use.

    Chlorine Dioxide A sudden failure of the sensor can lead to dangerous over-metering. Take appropriate precautions in this case! Check system for odour, check water for abnormal discolouration. In case of strong over- NOTICE metering, the DPD-1 measurement can remain colourless because the dye is bleached by the chlorine present.

  • Page 16: Calibration

    1.9. Recommendation: Weekly control, if necessary more frequently. In case of a necessary recalibration, operation with a TriOS controller is recommended. An integrated wizard guides the user step by step through a calibration menu. The value determi- ned analytically in parallel by the DPD method is set as the reference value in the controller.

    6.2. If you have further questions on this topic, we would be pleased to help you. Please contact our customer service at support@ trios.de. 6.2 Maintenance and inspection The sensor should be checked regularly for contamination, fouling and bubbles on the outside of the membrane. Avoid con- tamination of the membrane with particles, condensation etc.

  • Page 19: Electrolyte Replacement

    Malfunction and Maintenance Chlorine Dioxide 6.2.1 Electrolyte Replacement It is recommended to replace the gel electrolyte at least twice a year or when an adjustment is no longer possible due to readings that are unstable or too low. Carry out the following steps one after the other: Unscrew the membrane cap.

  • Page 20: Sensor Check

    Malfunction and Maintenance Chlorine Dioxide 6.2.3 Sensor Check An adjustment or a check of the sensor according to the DPD-1 method should be carried out regularly at specific intervals, depending on the requirements. Recommendation: Weekly control, if necessary more frequently. It is recommended to replace the electrolyte at least twice a year.
