Page 5: Introduction
DIGITAL WEIGHING SYSTEM INTRODUCTION The M2000D Digital Smart Weigh System utilizes Digital Load Cell (DLC) technology to provide high-level data integrity, easier maintenance, and lightning protection for your weighing applications. Load cell connections to the DLC Smart Box (mounted on the weighbridge) are the same as connections to traditional analog summation cards. -
Page 6: Installation Strategies
SECTIONAL TRUCK SCALE INSTALLATION GUIDE INSTALLATION STRATEGIES Mount the DLC Smart Boxes as close as possible to the weighing platform. The DLC Smart Boxes must be mounted in a NEMA rated enclosure, as the modules themselves are not watertight. Keep cable runs between load cells and the DLC Smart Boxes as short as possible, to help eliminate the contamination of analog load cell signals by RFI and EMI interference. -
Page 7: System Grounding
DIGITAL WEIGHING SYSTEM SYSTEM GROUNDING The M2000 Digital System provides state of the art lightning surge protection. In order for surge conditions to be diverted properly, a good earth ground path must be in place. Since the M2000D indicator is optically isolated from the DLC modules, both ends should be grounded to a good earth connection. -
Page 8: Getting Started
• Wire the rest of the sections the same way, with odd numbered cells on one side, even numbered cells on the other. In the case of two DLC modules, loadcell numbering will restart at 1 on the Secondary DLC module. (See Navigating the M2000) Section Section... -
Page 9: Setting The Dlc Id Jumper
DIGITAL WEIGHING SYSTEM SETTING THE DLC ID JUMPER When using two DLC Smart Boxes, the M2000D indicator needs to differentiate between the Primary and Secondary modules. An ID switch must be set via the ID jumpers in the bottom right hand corner of each module. For systems utilizing only one DLC Smart Box, the jumpers must be in the “Primary”... -
Page 10: Wiring Loadcells To The Dlc Smart Box
SECTIONAL TRUCK SCALE INSTALLATION GUIDE WIRING LOAD CELLS TO THE DLC SMART BOX Load cells are wired to the DLC Smart Box using 5 pin terminal connectors. The connectors can be unplugged from the DLC to make wiring easier. The Primary DLC Smart Box will always contain Section 1. -
Page 11: Wiring Dlc Smart Boxes To The M2000D Indicator
DIGITAL WEIGHING SYSTEM WIRING THE DLC SMART BOXES TO THE M2000D INDICATOR The scale wiring requires 2 pairs of shielded wire (one pair for power delivery and one pair for data communications) plus a separate shield conductor. The recommended cable type is Beldon 9873 20 AWG or equivalent. For cable runs over 100 feet, Beldon 9773 18 AWG or equivalent is recommended. - Page 12 SECTIONAL TRUCK SCALE INSTALLATION GUIDE ONE DLC SMART BOX DLC SMART BOX CTRL - CTRL - CTRL + CTRL + (Fig. 5) TWO DLC SMART BOXES PRIMARY DLC SMART BOX CTRL - CTRL + CTRL - CTRL + SECONDARY DLC SMART BOX CTRL - CTRL + (Fig.

(Press 3, [PRINT/SELECT]) and the new value of 20 should be displayed. Hit the [CLEAR] key to cancel and return to weighing mode. NOTE: ALL parameters for M2000 Indicators are entered and edited in this way. SETTING SCALE CAPACITY (PARAMETER 4) To select Parameter 4, press 4 on the keypad followed by [PRINT/SELECT]. -
Page 17: Allocating Sections
DIGITAL WEIGHING SYSTEM ALLOCATING SECTIONS (PARAMETER 521) For an initial scale installation, the M2000D indicator needs to be told how many sections are in the scale. The scale must be installed and wired to the DLC Boxes before executing this command. There can be a maximum of 8 sections per scale. -

SECTIONAL TRUCK SCALE INSTALLATION GUIDE EXAMPLE: Weight Correction on Section 2. Section 2 is weighing 9920 lbs. The actual weight on the scale is 10,000 lbs. Use the Quick Select Method to select Section 2. Enter 2 followed by the [TARE] key. -
Page 23: Serial Communications
9600 baud. DATA BITS (PARAMETER 27 - COM2 ONLY) COM1 on the M2000 is fixed at 8 Data Bits. However, if EVEN or ODD Parity is selected then 7 Data Bits will automatically be used. COM2 allows for independent selection of Data Bits. -
Page 24: Parity
String Format for COM2: Parameter 35 Several different indicator string formats are supported on the M2000. If creating a custom Output string for a ticket, the Com port connected to the printer must be set to 99. (See M2000 Ticket Formatting Guide) -
