Control room consoles

Isolation or emergency shutdown (ESD) valves should be installed to stop fuel flow and the process feed flow into the heater in the event of heater tube rupture. These valves can be automatically actuated by controls or safety interlocks or can be manually operated remotely. Remote actuation can be from a control room console or in the field field actuation stations should be located at least 50 ft (15 m) from the heater. It is also common to provide a manual block valve, located at least 50 ft (15 m) from the heater, on each of the fuel and process feed lines. These should be accessible to operators in the event of an incident involving the heater.

Control room consoles are where the main observation and commands to process systems are undertaken and are vitally important for safe plant operations. Proper display, ease of operation, and understanding are required parameters for these operations. Common major concerns for any of these facilities include the following ... 

The term control panel refers to the instrumentation console in a central control room through which process information is communicated to the process worker and via which the worker changes the state of the process. This category includes display elements such as chart recorders, bar indicators, dials, and modem VDU-based systems together with control elements such as buttons, switches, track balls and mice. The control panel is the human-machine interface (see Chapter 2) that has traditionally received the most attention from human factors specialists. 

Manned control rooms should always be provided with hardwired ESD activation points located on the main control console easily accessible to the operators. 

Control Room. The accelerator control room was designed to enable the operator to view the entrance to the cell directly from the control console as a safety precaution (Figure 4). From this console an operator can...

The central control room provides surveillance and direction for all phases of TOCDF activities. It is kept at a higher positive pressure to prevent the possibility of any agent entering it, and the air intake is doubly filtered. Several consoles Une the room, each with two advisor screen monitors, two closed-circuit TV monitors, and a keyboard through which commands are entered to control plant operations. Redundant computers, software, and plant instrumentation ensure that continuous realtime control is maintained. 

Adjacent to the scan room are the electronics room for all electrical units, connecting wires, etc., and the control room where the console for the operation of the scanner is installed. There should be a glass viewing window possibly of lead, between the scanning room and the control room for the operator to observe the patient during the study. Alternatively, a video camera in the scanner room and the monitor in the control room can be installed. The dimension of the electronics room should be approximately 10 x 8 feet and that of the control room should be about 10 x 10 feet. However, these dimensions can vary, if needed. All these rooms are interconnected for easy access to each room. Because the electronics modules and scanners generate... 

More links were broken due to maintenance work that was being done in the control room to reorganize the physical sectors. This work led to unavailabiUty of the direct phone line used to communicate with adjacent ATC centers (including ATC Karlsruhe, which saw the impending collision and tried to call ATC Zurich) and the loss of an optical short-term conflict alert (STCA) on the console. The aural short-term conflict alert was theoretically working, but nobody in the control room heard it. 

Position Indicators. The regulating- and shim-rod posit ion indicators have been designed to indicate the exact position of the rods at any time. Rod positions may be read by means of direct-ruading dial indicators at the. platform of the top plug and by means of remote selsyn-driven (dial) indicators at the console in the control room. 

The control console, located in the center.of the reactor control room (see Section 5.7.1), is made up of five unit panels laid out on a circular arc of 51 in. radius and extending some 240°. At the center of this arc, the operator will be seated in a movable chair, giving him easy access to the information and control elements spread out on the panels. At his left hand is a telephone by which he can communicate with other control and instrument centers, such as the one in the Process Water Building. By looking over the top of the console, which is 40 in. from the floor, he can see the instrument panels, particularly panels D to H, standing in an arc directly in front of him. 

The control room layout includes an instrument panel to accommodate the initial requirements for indicators, recorders, and annunciators with a number of spare and- partially utilized panel sections for future requirements.. This panel board, - facing in the direction of the reactor, is composed of eleven 4-ft-wide by 9 ft-high sections and extends the full length of the room with a rear access door at each end. Six panel sections, three at each end of the board, lie in a straight line. These two end panel groups are connected by the central panel sections which are arranged on a radius of approximaxely 7K ft to allow for the control console. 

The console in the control room mounts all devices for effecting manual control of the reactor control indicating devices, and some indicating instruments. Other reactor indicating instruments and recorders are located on the central panel sections immediately in front of the console, as indicated in Fig. 5.8.A. 

For these reasons the Mock-Up was provided with two complete shim-safety rod channels and one regulating rod channel. The control, room contained the operating console which served as the study model for the MTR desk and a relay panel, both equipped with the necessary electrical equipment for testing system performance. 

Control rooms housing electrical equipment should be pressurized with clean filtered air and entrances should preferably be fitted with two sets of interlocked doors to seal the factory environment, with only one operable door at a time. All electrical cabinets and consoles should be pressurized with fan units fitted with filters and due care should be taken to ensure that there is sufficient air available to remove excess heat from the cabinets. 

The main control room (MCR) panel is comprised of an integrated set of operator interface panels (e g., main control console, large display panel). The safety-related panels are seismically qualified and provide grounding, electrical independence and physical separation between safety divisions and non-safety-related components and wiring.

CONTROL ROOM DESIGN — PLANT SAFETY PARAMETER DISPLAY CONSOLE... 

Provision of a plant safety parameter display console was made a requirement by 10 CFR 50.34(f), (Reference 2). The functional criteria and design requirements for the SPDS were defined in NUREG 0737 (Supplement 1) (Reference 3). The primary function of the SPDS and the display console is to help operating personnel in the control room make quick assessments of plant safety status during abnormal and emergency conditions. 

The main control room accommodates an operator console, a supervisor s console, safety consoles, the wall panel information system large screen displays and the DAS panel. The operator console provides the displays and controls to start up, manoeuvre, and shut down the plant, and it is designed to be staffed by one to six operators. The operator interfaces are the duty system control displays, soft controls, alarm presentation system displays, computerised procedures displays, as well as the VDU monitors, keyboards and mice. The supervisor s console is a smaller version of the operators console, and is designed to be staffed by one or two personnel. The primary dedicated safety panel and VDU-based safety system workstations are located at the centre of the operator console, with a secondary safety panel located in close proximity to the supervisor s console. The DAS panel is located at a sidewall in the main control room. The main control room also includes communication devices, document lay down areas, printers and storage space. A meeting table is provided and equipped with a VDU-based workstation to allow access to the duty control system by, for example, a technical advisor or shift manager, without disrupting control room operations. In close proximity to the main control room are the shift supervisor s office, the operations staff area, an operations woik area, restrooms, and kitchen facilities. 

Control room monitoring is commonly undertaken with computer console video displays to indicate and control the process immediately.To reduce the frequency of errors the following technical solutions should be implemented ... 

The control room is also equipped with a temperature console where as many as 140 temperature points in the cold boxes can be read. Any 12 of these points can be recorded continuously and give us the means to follow and chart dynamic conditions of plant components. In addition to controls, the graphic panel has a number of flow recording devices, which make it possible to make up daily material balances and production records of the plant. 

A discussion as to developments in control room design is provided by Urso (2013). It considers the fact that current designs tend to create islands that tie operators to a particular console, and so limit communications with those working at other work stations. The article also notes that younger technicians are used to accessing information with smart devices and expect to see something similar in the work environment.
