3. Introduction and Block Diagrams The FlintWeigh II IPC Weighing terminal is the ideal solution for approved (legal for trade) or non-approved (industrial) weighing applications. In legal for trade applications the instrument has an alibi memory which allows to trace back weighing results for years. The integrated weighing system controller (WSC) provides connectors for standard load cells. Additionally there is an option to connect type RC3D digital load cells by an RS485 bus system.

4. Weighing System Controller and Technical Characteristics The following section describes the technical characteristics of the relevant weighing components within the weihing terminal. Hint: You can find the industrial PC’s technical characteristics and further important information in the operation manual of your instrument. The weighing system controller is executed as a PCI plug-in card according PCI specifications Rev. 2.2. It can be used in “half-length” PCI slots (at least 155 mm long).
4.1.1. Connector for Standard Load Cells The connectors J1 and J2 can be used for connecting standard load cells in 4– or 6–wire technique. Hint: If 4–wire technique will be used, then pin no. 1 and no. 2 as well as pin no. 4 and no. 5 have to be shortcircuited. It is mandatory to interconnect the shield of the connection cable with one of the shield connector pins (pin no. 3, 6 or 9). Pin no.
4.2. Important Information about the Operation of Digital Load Cells It is allowed to connect up to 16 digital load cells (e.g. type RC3D) to the weighing system controller. The integrated power supply can provide electrical power for up to 8 digital load cells. IMPORTANT: If you connect more than 8 digital load cells, then it is mandatory to power all load cells from an external power supply.
4.4. Weighing Modules for the Operation of Standard Load Cells The weighing system controller can accommodate up to two weighing modules. Depending on the application – legal for trade scale or industrial application – it can be selected among various weighing modules. Weighing module type LDU 68.1 LDU 69.1 LDU 78.1 Accuracy class LDU 68.2 Not approved Certificate no. Intervals "n" acc. Kompmodeng: nind Internal resolution DK0199-R7610.04 Rev.1 10.000 DK0199-R7611.08 Rev. 1 10.000 DK0199-R7610.
Step 5: Put the supplied wire strap from the upside through one of the holes of the controller card. Lead the wire strap on the bottom side to a second hole of the controller card and from there back to the upside. Tighten the wire strap by hand. Step 6: Reinstall the weighing system controller into the weighing terminal. Fix the interlock of the PCI plug-in card. Close the enclosure of the weighing terminal properly. 4.6.
5. Installing the Device Driver The device driver for the weighing system controller consists of two parts. A driver for the PCI-card and a driver for the serial port.
Fig. 5.2: Selection of the installation option and source for the card driver A window for selecting the installation option and source opens. In this window you enable the option "Search for the best driver in these locations". Now select exclusively the option "Include this location in the search". After clicking "Browse" you can select the source directory for the card driver, here e.g. "C:\install\WSC\Drivers\nxWeigh_XP\" Click "Next" to continue. Fig. 5.
5.2. Installing the Port Driver The installation of the port driver will be shown exemplarily for the Windows XP operating system and a new driver installation. Preparation: If any version of the port driver is already present in the PC system, then first delete the installed port driver.
Fig. 5.7: Note about the Windows Logo Test Confirm by clicking "Continue Anyway". Fig. 5.8: Completed Installation After some files from the operating system have been copied, the card driver installation is finished. Finish the installation by clicking "Finish". 5.3. Used COM Port The interface driver of the weighing system controller will use the next free COM port automatically. For checking or changing the used COM port no.
6. FlintWeigh II Software Installation The FlintWeigh II software displays the continuously measured weight value of the weighing system controller within a graphical window in a legal for trade quality. FlintWeigh II also provides an OLE interface. External programmes can access the data and information within FlintWeigh II by using OLE functions. All windows and control buttons are part of the OLE interface.
7. Weight Display and Control Buttons Fig. 7.1 : Weight display and control buttons (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) (12) Display window FlintWeigh II Logo Software version and checksum Weight value Weight unit* Service functions Displayed scale (no.
8. FlintWeigh II Configuration 8.1. Basic Setup during the Commissioning When you commission FlintWeigh II for the first time, following basic setup has to be done: • Sensor interface and Sensor type ( standard load cells OR digital load cells) • Scale system • Data memory • Interface to remote display and remote display type • Gravitational factor, if applicable These basic settings will be described in this chapter. Fig. 8.1 Weight display before commissioning Start the main programme ”NW11F.
8.1.1. Configure the Alibi Memory In legal for trade applications the recorded weighing results will be stored to an approved data memory, the so called alibi memory. Fig.8.3 Configure the alibi memory In the standard installation the data memory will be automatically created in the FlintWeigh II programme directory. Generally the location for the data memory can be selected freely, e.g. it is allowed to choose another local directory or any network drive.
8.2. Language and other Settings FlintWeigh II has some setup parameters, which can be set up before or after the commissioning. If you have configured a multi scale system, then first select the wished scale (“1” or “2”) in the weight display (Fig. 7.1). Fig. 8.
8.3. Scale with Standard Load Cells Important: The sensor type already has been set to “LDU” (see Fig. 8.2; Register “Communication“). If you have to configure a multi scale system, then select the wished scale no. ("1" or "2") within the weight display (Fig. 7.1). 8.3.1. Define the Scale Parameters Fig. 8.
Min. capacity: Minimum load of the scale (as a multiple of the scale interval e1) Test weight: Weight of the calibration weight (as a multiple of the scale interval e1) Changeover threshold 1/2: Only for multi-range / multi-interval scales: Transition points for range or interval (as a multiple of the scale interval e1) Important: For saving all scale parameter settings you have to close the window FlintWeigh II Settings afterwards. Now the weight display (Fig. 7.1) should show a random value.
Scale type: Setting Single-interval Multi-range Multi-interval Comment The scale has exactly one weighing range with a constant scale interval The scale has 2 or 3 weighing ranges with different scale intervals. If the current gros value of the measured weight falls within the next weighing range and larger scale interval (changeover threshold 1 and 2), then the larger scale interval remains active until the scale will be unloaded and will return to the zero point.
8.5. Calibrate the Scale Important: Before you can calibrate the scale you have to define the basic setup (see chapter 8.1) and the scale parameters (see chapter 8.3 respective 8.4). If you have to configure a multi scale system, then select the wished scale no. ("1" or "2") within the weight display (Fig. 7.1). 1. 2. 3. 4.
8.6. Optional Linearisation of the Scale Curve The standard scale calibration may be supplemented by a linearisation with up to 5 correction points. Hereby the correction points have to be in a stricly increasing order, which is: Min. capacity < Point 1 < Point 2 < Point 3< Point 4 < Point 5 < Max. capacity of the scale Important: Before any linearisation you have to define the basic setup (see chapter 8.1), the scale parameters (see chapter 8.3 respective 8.
8.7. Optional Use of Digital Outputs After opening the service functions (window FlintWeigh II Settings) and selecting the register “Parameters“, you can assign a functionality to the digital outputs: Fig.8.11 Register “Parameters“ for defining the digital outputs Step 1: Select the source to control the output Allowed settings are Scale 1, Scale 2 and Combination. Step 2: Assign a functionality to the output Allowed settings are: Setting “Off“ “Limit“ “Traffic light“ 8.7.1.
8.7.2. Traffic Light Control Fig.8.13 Example for the traffic light control The implementation of a traffic light control requires following setup: 1. Define the function “Limit“ for digital output 1 2. Define the function “Traffic Light” for digital output 2 3.
