3. INTRODUCTION 3.1. Overview The type FAD-30 A/D Converter Series consists of powerful and economic state-of-the-art instruments for static and dynamic weighing applications plus force and torque measurements. Each instrument of the series converts the analogue low level signal from a load cell or a strain gauge sensor to a digital high-resolution and high-accuracy signal and transmits the digital data to an external PLC or PC system.
FAD-30PB FAD-30PN FAD-30EN FAD-30CO Bipolar signal input in Force and Count modes 500 to 100 000 counts external resolution at calibrated data Unipolar 1 million and bipolar 2 million counts is adjusted and filtered to external resolution in count mode High internal resolution up to 8 million counts Up to 800 conversions per second Standard Serial interface RS-232C Standard Serial interface RS-485A Modbus RTU interface Profibus DP-V1 interface ProfiNet interface Ethernet (Modbus TCP/IP or BSI) interface
Communication and Setup: Serial interface RS-232C: Other interfaces Response time Setup and calibration 9600 baud (8,N,1) Depends on instrument type < 4 ms (delay after each read or write command) By PC software via RS232C, backup data stored on PC Power supply: DC power supply 10 to 28 VDC, < 200 mA, not galvanically isolated Environment and Enclosure: Operation temperature: Enclosure and protection Between -10 °C and +40 °C at maximum 85% RH max, non-condensing Polyamide, for DIN-rail mounting, IP20

4. INSTALLATION PRECAUTION: Please read this manual carefully before you install the instrument. If you apply all recommendations in this chapter you will increase the reliability and long term performance of your system. 4.1. Recommendations 4.1.1. Control Cabinet Design Warning: Please follow the following warnings for designing the control cabinet which will increase the reliability of your system. The control cabinet should be designed therefor the A/D converters can operate safely.
The quality of the instrument‟s ground will determine the accuracy and the safety of your measuring system. A proper ground connection is needed to minimize extraneous electrical noise effects on the measurement. A poor ground can result in an unsafe and unstable operation. It is important that the instrument should not share power lines with noise-generating equipment such as heavy load switching, motor control equipments, inductive loads, etc.
5. SETUP PRECAUTION: Please read this manual carefully before energizing the instrument. Perform the commissioning according the procedure given in chapter 4.3. Only trained person are allowed for commissioning, checking, cleaning and servicing of the instrument. The interference of untrained person may cause some unwanted damages or injures. FAD-30 series instruments are setup and calibrated by the xFace software supplied with the instrument.
5.3. A/D Converter Setup and Calibration WARNING: Read this manual carefully before you setup and calibrate the instrument. This will increase the performance of your weighing system by applying proper setup and calibration. Visual Weight Display: Displays the weight, count or force value Toolbox: Contains shortcuts of some special commands A/D Converter Parameters: This block allows the user to setup the A/D Converter‟s parameter related to the operation mode. Refer to chapter 5.3.
Motion Detection This parameter defines the motion detection window which determines a stable weighing. If motion detection is not required, this parameter can be disabled. The available motion detection window values are: Weighing and Force Mode: Disable ± 0.3e ± 0.5e (default setting) ± 1e ± 2e ± 60 ± 100 (default setting) ± 200 ± 400 Count Mode: Disable Power On Zero This parameter enables automatic zeroing after powering on the instrument.
Checksum The checksum can be enabled or disabled within BSI and Continuous output data format. The checksum calculation can be found in the related data format description. Default setting: „Enable‟. Carriage Return Carriage Return can be enabled or disabled within Continuous output data format. Default setting: „Enable‟. Line Feed Line Feed can be enabled or disabled within Continuous output data format. Default setting: „Enable‟.
Mode selection FAD-30 instruments have three operation modes which are: Count Mode: Weighing Mode: Force Mode: Filtered and normalized ADC count data will be transmitted in this mode. The calibration is performed at the PLC, if any. Unipolar weight data in calibrated weighing unit will be transmitted. This mode is compatible to OIML R76 and EN 45501. Bipolar or unipolar force measurement data in calibrated force unit will be transmitted. Select the scale operation mode and the polarity.
Zero Adjustment If your scale has a residual zero drift you may perform a zero adjustment only. Select “Zero Adjustment” and press the “Start” button. Then the zero calibration window will be displayed. Unload the scale and click the “OK” button. The [WAIT] message appears on the virtual display during the zero adjustment. Approximately 5 seconds later the zero adjustment will be finalized. Note: Zero adjustment is also performed over the bus interface.
5.4. A/D Converter Performance Test The scale performance test should be performed before you install the bus connection. The tests are linearity, repeatability and eccentricity. You can follow the test at the virtual display and/or status tab which show the measurement data, the instrument data and the software version. For convenience keys for Taring, Zeroing and Clear are located in this tab. 5.5.
5.8. Continuous Output Data Structure (for FAD-30 + FAD-30MB only) The continuous data output of the instrument will be transmitted in the following data structure at the speed which is determined by the baud rate and the data length. The definition of the continuous data format is described below.
5.9. BSI Data Structure (for FAD-30 + FAD-30MB only) Depending on their functionality all new generation Flintec instruments launched on the market support the standardized command set with BSI data structure. This easy data format gives a reliable and fast interface for communicating with PLC or PC for process control or transactional applications. You can expand your system with additional scales from Flintec without having to change your application program base. General Rules: 1. 2. 3. 4.
