    - Skilled personnel must have carefully read and understood the operating instructions prior to beginning a ny work. -The operating instructions are part of the product and must be kept in the immediate vicinity of the DTW and readily accessible to skilled personnel at any time.
  • Page 4: Safety Instructions

    - Keep unqualified personnel away from hazardous areas. For installation and start-up of the DTW the personnel has to be familiar with the relevant regulations and directives of the country and must have the required qualification. They must have knowledge of measurement and control technology, have to be acquainted with electric circuits, are capable of carrying out the work described and can independently recognise potential hazards.

  • Page 6 Safety Instructions (Continued) 3.5 Ex-Marking and Approval Please make sure to read the operating manual before mounting and start-up of the DTW-transmitter! Danger! Danger to life caused by loss of explosion protection Non-compliance with these instructions and their contents can lead to loss of explosion protection.
  • Page 7: Start-Up, Operation

    Start-Up, Operation Function The digital temperature transmitter DTW is a universal measuring transmitter for resistance thermometers and potentiometers. It is configurable via PC. The device transforms resistance values or relations (potentiometer) into a proportional current signal. At the same time the sensors are constantly tested to ensure faultless operation.
  • Page 8: Mounting

    Working in flammable atmospheres can cause explosion hazards, which may lead to death. Gefahr - Conduct set-up work only in areas without explosion hazards! - In areas with explosion hazards only use DTW-transmitters approved for this specific type of hazardous area. Please comply with the approval on the product label! - Check the delivery immediately for completeness and obvious faults.
  • Page 9 Transmitters with ia-marking may also be used in supply circuits of type ib with the same connection parameters. With this, the entire measuring circuit (including the sensor circuit) is an ib circuit. DTW-transmitters which were operated with supply circuits of type ib may not be re-used with supply circuits of type ia.
  • Page 10 - Install DTW head version only in grounded thermometer-heads! - The connection of a resistance sensor (e. g. Pt100) to the DTW rail version is made with shielded wiring - The shielding has to be bonded with the casing of the grounded thermometer.
  • Page 11 This is especially important when the EMC-requirements are combined with long leads to the sensor. See illustrations on this page. The DTW rail version and long lead lengths over 30 m make a shielded wire mandatory. Grounding DTW Rail Version Shielded...
  • Page 12 When mounting a connection head inside the cover, use suitable screws and matching washers. Mounting with Top Hat Rail Adapter A mechanical adapter is available as accessory. It can be used to fasten DTW head version transmitters to a top hat rail. (See chapter 11, Accessories) 4.4.4...
  • Page 13: Electrical Connection

    - The bonded wires have to be connected properly. Please control the connections, only properly connected wires can guarantee full functionality. The DTW transmitter is protection class 3 equipment for the connection to low voltages which are separated from supply voltage or voltages higher than AC 50 V, respectively DC 120 V.

  • Page 16: Configuration

    - Please write down any modifications of your configuration on the product label! Use a water-resistant fibre-tip pen. To configure the DTW a simulation of the input value is not necessary. Only for the functional test do you need to simulate the sensor.
  • Page 17: Troubleshooting

    - Do not use any pointed or hard objects for cleaning to prevent damage to the electrical contacts. - Verify in advance if the right voltage supply and the right type of wiring has been chosen. - For contact data, see data sheet DTW or cover/backside. Note: In case of unjustified reclamation an additional charge is possible.

  • Page 19: Maintenance, Dismounting, Return, Cleaning, Disposal

    Dispose device components and packaging materials in accordance with the respective waste treatment and disposal regulations of the region or country to which the DTW temperature transmitter is supplied. Collect electrical and electronic parts separately. Separate metals and plastics. Dispose of printed circuit board assemblies professionally.
