Important hints for mounting, installation and starting are introduced in chapter 3. A short intro for structuring and parameter input of the DC155, as well as the complete functionality of the front keys and the display can be found in chapter 4. -
Page 5: Basics
DC155 2 Dosing controller DC155 Page 5 2.2 Basics 2.2.1 Units for preset, sum counter and flow The first step to configure the DC155 is to define the physical unit for preset, sum counter and flow. There- fore sufficient unit symbols are implemented into the DC155 (e.g. gram (g), kilogram (kg), tons (t), liter (l) etc.) To define the flow several time units are available. - Page 6 Page 6 2 Introduction DC155 DC155 Beside it is possible to define a maximum preset, to allow only equal or smaller presets to be set. The DC155 has three free programmable digital outputs. In the example above two of them must be re- served for valve control.

Page 10: Temperature Compensation (Requires Pt100- Option)
Page 10 2 Introduction DC155 DC155 2.5 Temperature compensation (requires Pt100- option) Any fluid has a specific expansion coefficient γ, i.e. in general, the volume of the fluid increases with its temperature. So using a volume measurement sensor for a mass dosing application, introduces an inaccu- racy into the dosing process, if the temperature changes. -
Page 11: Flow Monitoring
DC155 2 Dosing controller DC155 Page 11 2.6.2 Flow monitoring Flow fluctuations are considerable disturbances particularly if a reactor will be filled simultaneously with several substances or the flow exceeds the flow sensor limits. The DC155 can monitor min and max flow limits. If flow exceeds limits, the DC155 interrupts the batch process after a programmed time delay and indicates the disturbance on the display. -
