GENERAL INFORMATION 3.1 Hardware Description The FGM 160 Field Computer, illustrated in Figure 1, is designed as a distributed system. The FGM 160 consists of five or six modules, the Digital Signal Processing (DSP) module, the Analog Front End (AFE) module, the Pressure & Temperature (P&T) module, Input/Output (I/O) module, Intrinsic Safe Barrier (IS Barrier) module, Surge Protection module and the Local Display.
3.1.2 Power Supply The FGM 160 requires 24 VDC power supply (nominal). If 24 VDC is not available, an optional 110-230 VAC/24 VDC converter can be supplied by Fluenta. For detailed equipment information and equipment ratings, please refer to Hazardous Area Installation Guidelines [1].
3.1.4.5 Pulse/Frequency Output The FGM 160 can be also configured to provide a pulse or frequency output signal. The pulse output will represent an incrementation of the totalizer (of e.g. volume or mass), whereas the frequency output will represent a process parameter (e.g. volume flow rate, mass flow rate etc.)
3.1.5.4 Input/Output (I/O) Module The Input/Output Module is the interface between the FGM 160 in hazardous areas and equipment in safe areas. At the I/O Module, 24 VDC (nom.) supply voltage is converted to the required operational voltages for the other modules. Furthermore, all signals and communications to and from the DCS system and UFM Manager are handled by this unit.
FGM 160 Operating Instructions 3.1.6 Non-Resettable Counter Function The non-resettable counter function will record and keep the totalized volume and mass. The totalized values are accessible through the DCS Modbus interface or through UFM Manager. Figure 3 Electronic modules 3.2 Firmware Description In the following sections a general description of the firmware for the different modules is outlined.
Modbus or HART interfaces. 3.3 Device Integrity 3.3.1 Self-Checking The FGM 160 performs a self-checking sequence, where it checks that inputs from the transducers and Temperature and Pressure transmitters are within a valid range, and that other functions are operating as intended. 3.3.2...
It should be noted, UFM Manager is required to replace the default settings with actual applicable settings provided by customer. Fluenta service engineers and partners will always set up the FGM 160 according to the latest submitted parameters from the Client when installing and commissioning the FGM 160. Fluenta service engineers and partners always have the UFM Manager with them.
24 VDC supply or through a 110-240 VAC/24 VDC converter. 3. Turn on the power to the FGM 160. There is no power switch on the FGM 160 Field Computer, so the power must be switched by an external switch or similar, preferably in safe area.
[4]. 4.4 Local Display Functions The FGM 160 is equipped with a local LCD display mounted at the front, and visible through the Ex-d safety glass. The display shows predefined process parameters from the FGM 160. Further, 4 status LEDs are visible at the front for the following status information: •...
E-mail: support@fluenta.com NOTE! Before any work can be carried out with the FGM 160 field computer, a hot work permit must be obtained. Do not connect or disconnect any signal wires unless the power is turned OFF! Do not open the Ex-d enclosure containing the field electronics in hazardous area, without making sure first that the conditions permit such action.
4.5.2 Error Check with UFM Manager Through the FGM 160 UFM Manager, data can be logged for trend analysis and evaluation. Figure 5: By pressing the “START Data Logging” button at the “Data Logging” tab, any or most parameters can be logged to a data file. The data log file name will be generated automatically based on the current date and time.
