GFC-IS November 2009 Technical Specifications ControlWave® Intrinsically Safe Gas Flow Computer (GFC-IS) The GFC-IS is delivered in a compact polycarbonate enclosure that has provisions for a display/keypad, DP/P/T transducer assembly, and 6 Volt battery/solar power system. The GFC-IS includes a base API 21.1 flow measurement application program, 2 user-configurable digital inputs (DI) or pulse inputs (PI), a DP/P sensor assembly, an RTD interface, and a shunt regulator for solar panel charging of an internal, lead acid cell battery. The CPU and I/O boards are located behind a shield in the enclosure and all wiring termination blocks are on a termination panel. You must wire all connections from the terminal panel or from the ISProx board out through a conduit on the right side of the GFC-IS enclosure in order to preserve the integrity of the intrinsically-safe rating. Hardware 32-bit ARM9 platform capable of dual-run flow computing and process automation operations. Gauge pressure or DP/P sensor assembly can be removed and replaced independently of the electronics. Precision RTD interface provides accurate temperature measurement. Low power consumption minimizes costs. Two serial communication ports. Base I/O includes 2 DI/PI. Optional I/O expansion includes 2 DI/DO, 4 DI, 2 DO, 2 High-speed Counter Inputs, and 3 AI (1-5 V). Integral LCD with optional, 25-key keypad allows operators to view and change configurable parameters, on site, without packing a PC. Application Areas ControlWave GFC is appropriate to all flow computer and chart replacements applications, including: Off-shore platforms. Compressor stations. Storage facilities. Transmission metering stations. Distribution/LDC metering/gate stations. Communications The GFC-IS has two built-in RS-232 communication ports and one RS-485 port. One RS-232 port (Com 1) is factory wired to the LOI port of the bottom of the GFC-IS enclosure. Inputs and Outputs The GFC-IS supports a variety of I/O options. The base unit includes two I/O ports that are userconfigurable as digital inputs (DI) or pulse inputs (PI). Additional I/O modules may be added including: 2 DI/DO, 4 DI, 2 DO, 2 HSC, and 3 AI 2 DI/DO, 4 DI, 2 DO, and 2 HSC RTD Input D301635X012 The ControlWave® Intrinsically Safe Gas Flow Computer (GFC-IS) is an intrinsically-safe integrated “all in one box” chart replacement. The intrinsically safe features of the ControlWave GFCIS are designed to prevent sparks or a release of energy that could ignite a hazardous atmosphere. The GFC-IS is UL approved as non-incendive for operation in Class I, Division 1 hazardous areas. ControlWave Intrinsically Safe Gas Flow Computer Remote Automation Solutions www.EmersonProcess.com/Remote GFC-IS November 2009 Technical Specifications Display/Keypad The GFC-IS display is comprised of a four line by twenty character liquid crystal display with adjustable contrast. The display allows you to view and modify variable values and associated status information via an ACCOL3 Function Block. Variables include inputs, process variables, calculated variables, constants, setpoints, tuning parameters, outputs, and alarm state. You can input data into the GFC-IS via a 2-button or 25-button keypad. Each key on both keypads has a microswitch for positive tactile feedback. IStran The IStran is the communications interface that allows the GFC-IS to communicate with devices located outside of the hazardous area. The IStran provides 500 V dc isolation between the two devices, and also allows the GFC-IS to receive power from outside the hazardous location. The IStran allows the GFC-IS to control power to a radio or modem located outside the Division 1 area, and operates at up to 19200 bps. ISProx The Intrinsically Safe Proximity Sensor Interface (ISProx) provides an intrinsically safe interface to one or two variable impedance proximity sensors (NAMUR Gap Sensors). The ISProx conditions and converts incoming signals to open drain outputs (DOs) which in turn drive digital inputs (DIs) or highspeed counter inputs (HSCs). TeleCounter The TeleCounter is an optional pulse counting device and odometer. The integrated TeleCounter assembly directly mounts to a rotary positive displacement meter, and is mounted to the bottom of the GFC-IS enclosure by a water tight gasket. The TeleCounter can be configured to accept a clockwise or counterclockwise turbine meter shaft rotation with index rates of 1, 5, 10, 100, 1000 CF/Rev or 0.1, 1, 10, 100 M3/Rev. Firmware/Software Features ControlWave GFC is pre-programmed to meet API 21.1 requirements for a two-run metering station with networking via BSAP or Modbus. PC web style menu pages are pre-configured for all user operations. ControlWave Designer is an IEC 61131-3 programming environment that allows you to modify the base application or create a completely customized program. ControlWave Designer includes an extensive library of more than 200 basic IEC 61131-3 functions and function blocks common to many IEC 61131-3 based products. In addition to the basic functions and function blocks, ControlWave Designer includes the ACCOL III function block library. This library includes over sixty function blocks that are valuable for use in oil & gas and process measurement & control applications. The ACCOL III function block library is designed to take full advantage of the significant features offered by the ControlWave GFC-IS. Data Integrity The GFC-IS ensures data integrity, in the event of a communication interruption, by storing critical timestamped alarm and historical data in the controller memory. This data is then retrieved when communication is restored. Sensor Assembly Using the sensor assembly integrated in the instrument package is the easiest implementation for a single meter run; however, the base application program also allows use of external transmitters, with or without the integrated sensor assembly. Most two-run systems use the integrated sensor assembly for the first run and three 1-5 V transmitters for the second run. Mounting The GFC-IS can be remotely mounted on a wall, a panel, or a two-inch pipe. It can also be mounted directly on the pipeline by utilizing a manifold block. Options The GFC-IS supports the following: Integral, Bristol gauge pressure or multivariable (MVT), DP/P sensor assembly and upper range limits. Bendable RTD assembly, pre-wired. Thermowell. I/O card, including 2 DI/DO, 4 DI, 2 DO and 2 HSC/DI and, optionally, an additional 3 AI, 1 AO. Choice of integral, battery and solar power systems. Stainless steel manifold adapters. A mounting bracket which affixes to the neck of the housing and allows installation on a wall or 2” pipe. RS-232 interface PC cables are available in either 10 Ft. or 25 Ft lengths. 6 Volt IS solar panel.
