  • Page 4: Introduction

    1 Introduction 1 Introduction We congratulate you on the purchase of the CDF test equipment. With this equipment, you have acquired a high-quality test device for the real- ization of the freeze-thaw resistance test. Equipped with a microprocessor- controlled controller with internet interface, the device complies with the state of technology and thus meets the requirements of the future.

    • Pentration into soil, water and sewage system is to be avoided. 2.3.1 Protectives and behavioral rules • Do not leave the lid of the CDF machine open. • Cover not used place in the CDF bath with some cover plates or dummy containers. • Wear eye/face protection.

  • Page 7: Reaction To Malfunctions

    2 Safety instructions • Avoid breathing vapors. • Avoid contact with eyes, skin and clothing. • Immediately remove product residues from the skin, gently clean the skin and dry thoroughly. 2.3.2 Reaction to malfunctions • In the case of safety-endangering defects and malfunctions, do not use the device and inform those responisible.

  • Page 16: Filling The System

    4 Principles of operation 4.3.3 Filling the system The amount of cooling liquid is about 100 liters (see chapter 4.3.4). The cooling liquid is filled into the testing bath and passes through the over- flow into the cooling liquid buffer (fig. 15, left). Fill the cooling liquid until the optimal level in the buffer is reached (fig.

    4 Principles of operation especially with the lid open is possible. By handling the samples addi- tional water is added to the cooling liquid, thereby changing the concen- tration of the water-glycol mixture. Check the antifreeze of the cooling liquid regularly. For quick and safe control we recommend to use a re- fractometer (fig.

  • Page 20: Operation Of The Controller

    Choose Start to start the system. The system starts at the specified cycle time. This time is retained even after switching off and can be changed in the menu cycle time (see chapter 5.3). For the CDF test 28 cycles of 12 hours each will be executed. The corresponding number of cycles will expire, if another profile is activated.

  • Page 21: Status

    The temperature profile and the number of cycles can be freely defined by the user in the menu Setup –> System Menu –> Profile inp. (see chapter 5.4.2). The CDF profile is activated by default. 5.2 Status From the status the current information about the status of the digital inputs and the temperatures can be obtained (fig.

  • Page 22: Setup

    Hint: selected temperature profile. For example in case of CDF test, when the system should start at 10 a.m. and the weathering should be determined at 1 to 3 p.m., the cycle time should be set to 7h and 30m. According to the temperature profile, 3 hours later the cycle time is 10h 30m and the real time is 1 p.m.
