  • Page 6: General Dangers And Precautions

    General dangers and precautions Please read the following warnings prior to initial start-up! The symbols used in the operating instructions are intended to call your attention to the safety risks. It is not enough to simply observe the symbol. It is important to read the full text provided in the safety instructions! This symbol indicates a potential risk to humans, equipment or the environment.

  • Page 7: Safety Instructions For Compressed Air Systems

    2.2 Safety instructions for compressed air systems In the case of unforeseen events, the energy stored in compressed air can cause material damage or result in injury. The risk increases with the operating pressure of the system. All work must therefore be performed by appropriately trained personnel.

  • Page 8: Important Application Notes

    Important application notes 3.1 Avoiding damage to the measuring probe Measuring devices are sensitive and must be handled with care:
 Avoid shocks, impacts and vibrations. Prior to installation, check that there is no condensation, oil or dirt at the measuring point! Should this be the case, repair and dry out the system! The measuring system is not suitable for use with compressed air with a high oil content, as directly covering the sensor with a film of oil impairs its response, blocks...

  • Page 9: Intended Application

    3.3 Intended application The new TPK portable series is intended to be used to measure the pressure dew points, pressure and temperature of clean, oil-free compressed air, which is free of any abrasive, corrosive, caustic, toxic, flammable and combustible components. For the scope of application and the calibrated measuring range, please refer to the technical data.

  • Page 10: Mounting Of The Device

    Mounting of the device 6.1 Safety instructions The device must only be used for its intended purpose. Installation of the controller and maintenance work must only be carried out by trained personnel. The power supply must be turned off for installation and servicing.

  • Page 11: Procedure For Installation

    If using compressed air of unknown quality, use a condensate separator or particle filter. Additional components must be suitable for the intended use! In EMC-critical environments the measuring chamber should be electrically isolated from the metal pipes of the compressed-air network. The use of a PTFE or Polypropylene double nipple is an example of a suitable solution.
