Caution To avoid circuit damage when working inside the unit, use appropriate electrostatic discharge precautions such as wearing a grounded wrist strap. The microprocessor features a single 32-bit internal data bus and a single 16-bit external data bus. Event and alarm log database. Typically, the software setup of a device that can often be defined and changed. Note: If the input voltage is greater than the 10-volt loop, then the loop voltage equals the input voltage.
Examples of these restrictions are distance from pipe flanges and hazardous area classifications. A typical example is for flow control with a pressure override loop. Gently slide the module into place until it contacts properly with the connectors on the backplane. History is one block of memory divided into two areas, one for Standard History and one for Extended History. Secure the expansion rack to the adapter plate by attaching two plate screws in the upper and lower left-most holes in the expansion rack. Division 2 locations are areas where gas, dust, or vapors can exist under abnormal conditions. Engineering Engineering and workplace issues.
. Local and company codes generally provide guidelines for power installations. Test with a ground system tester to make sure the pipeline to earth impedance is less than 2 ohms. The terminals and their functions are Pin 1 is Terminal A and Pin 2 is Terminal B. The gas volume is calculated from the difference between the flowing pressure and the static pressure of the gas. Area A user-defined grouping of database entities. Note: A tab on the module case prevents you from installing the module incorrectly.
Set Midpoint 1 If you are performing a two-point calibration, click Done. The point type attributes define the database point to be one of the possible types of points available to the system. Verify the input voltage, which should be a minimum of 8 volts dc refer to Chapter 3, Power Connections. Note: The real-time clock uses the super-cap to keep the current time when you replace the lithium battery. The Meter Calibration window displays.
Click Set Back to Factory Defaults. Chapter 6 Provides information on the dual-variable sensor that Dual-Variable Sensor provides static and differential pressure inputs. Can also mean the hardware assembly scheme. Record the discrete output state shown on the Discrete Output screen. Note: Modules contain no user-serviceable components. Holding Register Modbus term for an analog output number value to be read.
The grounding installation method for the FloBoss 100-Series depends on whether the pipeline has cathodic protection. Expose a minimum of bare wire to prevent short circuits. When working on units located in a hazardous area where explosive gases may be present , make sure the area is in a non-hazardous state before performing procedures. Strip inch of insulation from the wire. Coil Digital output, a bit to be cleared or set. As a precaution, save the current configuration and historical data to permanent memory.
Two ¾-14 pipe-threaded holes permit field conduit wiring and communications. Display Connection on Base Unit. To remove a wire channel cover: 1. Gently rock the module until it releases from the backplane and you can remove it from the base unit or expansion rack. Note: Follow good wiring practices when sizing, routing, and connecting power wiring. Rotary Meter A positive displacement meter used to measure flow rate. Select the configuration file you desire to restore.
The revision date of each page appears at the bottom of the page opposite the page number. The system alarm log has the capacity to maintain and store up to 240 alarms in a circular log. Integrity Alert Red Alarm Yellow Figure 7-1. Refer to Table 7-2, which provides a temperature-to-resistance conversation chart. The transducer electronics convert the pressure variables directly into a digital format, allowing accurate correction and compensation. Hold it securely to prevent it from falling. The differential and static pressure inputs are sampled once per second.
Please log in and try again. Secure the loop and remove it from service. Retrieve, save, and report events and alarms. Index Provides an alphabetic listing of items and topics contained in this manual. Extended History only receives the surplus memory not used by the Standard History. All other marks are the property of their respective owners. Examples of licensed applications may include flow or properties calculations and various user programs.
