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.
