ACS - Aprovis Controlling System
We have called on our experience from well over 100 steam generator projects for further development of the ACS APROVIS Controlling System, which is now available in the latest generation.
Communication and interfaces
The open interfaces of the control system and ControlPanel permit communication with superior control centres such as ProfiBUS DP, Ethernet IP, etc. There is the option of equipping the ACS system with a GSM, analogue or ISDN modem for fast fault diagnosis in the event of a malfunction. Data transfer using a USB stick directly at the ControlPanel is also possible. The resulting data can be quickly converted to meaningful diagrams.
Menu language
The latest ACS generation attaches great importance to the menu language: 5 languages are available as standard (German, English, Dutch, French and Italian). Other menu languages can be supplied on request.
Monitoring
Reliable operational safety is ensured by setting up different user levels. A limit value is stored for every safety-relevant parameter to prevent operators from making incorrect inputs.
The ACS features a clear and logical operating and fault message management system. The operating notifications are grouped into colour-coded malfunctions, warnings and messages. A date/time stamp tells the operator when a malfunction took place and when it was corrected and acknowledged.
Trending
All important operating states such as boiler pressure are recorded as individual trends and stored for several months at a time. The ControlPanel is equipped with a ring buffer that overwrites the oldest data first when the storage capacity limit is reached. Memory extension is possible using a standard USB stick. When an external memory resource is connected, the data will be automatically transferred, so clearing out the internal memory.
Operating control system
Control is possible in automatic or manual mode. In automatic mode the control processes are taken over by the control system, so preventing the occurrence of critical operating states. In manual mode the control system allows the operator to actuate all valves, flue gas dampers, etc. by hand if necessary.
