The Electric Power Research Institute reco… The design of the control system and related equipment shall adhere to the principle of Fail safe operation of all system levels i.e the failure of signal, failure of power or failure of any component should not cause a hazardous condition and at the same time prevent occurrence of false trips and provide reliable and efficient operation of the plant under dynamic conditions. More precisely,functionalist theories take the identity of a mental state to bedetermined by its causal relations to sensory stimulations, othermental states, and behavior. In the case of a revamp, indicate that the initial philosophy includes a functional replacement in-kind with some enhanced alarm and data historian features. i) The overall operation and control of the entire Coal Handling Plant, with acontrol desk and suitable control panel will be provided at the Main CHP Control Room .

Functional decomposition breaks down a large, complex process into an array of smaller, simpler units or tasks, fostering better understanding of the overall process. a. Caustic solution will be unloaded from the road tank-cars by operating any one of the Caustic unloading pumps. These functional relationships are also illustrated by the diagram in figure 1. rake mechanism drive motor and floculator agitator motor shall be operated from local start/stop push buttons to be located near it. v) The system cabinet associated with various local controls shall be located near the local control panels. I speak from experience, don't assume anything. A control philosophy solidifies basic definitions, principles and processes during the design and implementation of a process. Management Control System. i) The chlorination plant shall be controlled manually from local control panel located in chlorination system main control building. The term ICD – Interface Control Document, Interface Control Description, Interface Control Drawing – is common. Key elements of process control follow below: * By first monitoring a process for a period of time, we learn what to expect from the process (with regard to key characteristics such as the process average and amount of process variation). Functional Vs Non-Functional Testing: Functional Testing Non-Functional Testing; Functional testing is performed using the functional specification provided by the client and verifies the system against the functional requirements. i) The operation and control of Dematerializing Plant shall be through a PLC in Auto/semi auto mode. The control room operator shall be provided with colour graphic displays of the Ash handling plant and with sufficient details to allow proper control & monitoring of the plant function. iii) Each compressor shall be suitable for individual and / or parallel operation with other compressors at any demand rate from zero to maximum capacity . The PLC system shall be an integrated control and data acquisition system for providing control & monitoring of Plant water system from a, For overall operation and control of entire Plant water system, Temperature of pumps thrust bearing (HT drives only)———-High, Bearing vibration (for HT drives only)———-High.
