  • Page 24: Battery Replacement

    HIGH SPEED DIGITAL WEIGHT INDICATORS BATTERY REPLACEMENT ON THE M2000 The M2000 uses a 3 Volt Lithium Battery to run the real-time clock and backup the indicator’s memory. Power is drawn from the battery only when the indicator is disconnected from the 12 Volt power supply. So, if the indicator is in regular use, the battery should have a long lifespan.

  • Page 25: Installation

    TECHNICAL MANUAL INSTALLATION...

  • Page 26: Power Requirements

    A 12 Volt battery may be used to power the M2000. The M2000 draws 200 mA, which will allow the indicator to run from a full 12 Volt car battery for a long time. However, the M2000 provides no “Low Power”...

  • Page 27: Grounding Requirements

    GROUNDING REQUIREMENTS Proper grounding of weighing system components is essential to avoid problems with static, transmission line “noise”, and voltage surges that may damage the equipment. It is essential that M2000 Indicators have a good ground connection. STATIC ENVIRONMENTS To reduce static interference, some weighing systems should have a solid connection from the scale base to Earth Ground.

  • Page 31: Scale Systems With Multiple Loadcells

    These systems typically utilize a Summation board that is wired to the M2000A using 7 pin terminal connectors. The connectors can be unplugged from the M2000 to make wiring easier. • Terminate the loadcell wires at the Sum board, making sure each wire is securely fastened in the appropriate position.

  • Page 32: Wiring Power To The M2000

    HIGH SPEED DIGITAL WEIGHT INDICATORS WIRING POWER TO M2000 INDICATORS Pass the power cable through the strain-relief, into the enclosure (Not required for Slimline models).

  • Page 58: Scale Filtering Parameters

    The M2000 has 2 digital filters to provide optimal weight readings on the display in unstable conditions such as in-motion, on-board, and livestock weighing.

  • Page 59: Main Filter Setting (Digital Averaging)

    Heavy Main Filter. M2000 will be very slow in any small weight change. FASTSTEP FILTER THRESHOLD - PARAMETER 42 Description: Controls the how the M2000 switches from the Main Filter to the Faststep Filter. The threshold value is the number of graduations the weight on the scale must change before the Faststep Filter kicks in.
  • Page 60 M2000 currently switches to the Faststep Filter when the weight suddenly changes more than 4 lbs. 8. To achieve a stable weight display, we want the M2000 to remain in Main Filter Mode while the man is on the scale.

  • Page 61: Faststep Filter Sensitivity (Example)

    3. If vibrations are causing the M2000 to trigger Faststep Filter Mode to early, we can increase the value of Parameter 43. 4. The M2000 now needs to see the weight change of over 12 lbs for a longer period (more consecutive samples) before entering Faststep Filtering Mode.

  • Page 62: Linearity Correction

    USING LINEARITY TABLES TO SET SPAN Having different Span Values at different weight ranges helps to correct any structural or loadcell non-linearity. M2000 Indicators allow Technicians to set spans for up to 4 weight ranges using 4 linearity table entries.

  • Page 63: Example: Linearity Correction

    TECHNICAL MANUAL EXAMPLE: SCALE CAPACITY OF 5000 LBS, 1 LB GRADUATIONS. THE SCALE IS INITIALLY CALIBRATED WITH 2500 LBS. IF 5000 LBS ARE LOADED AND THE SCALE DOES NOT READ “5000”, THERE MAY BE A LINEARITY PROBLEM. The Indicator reads “4998”. Using the Span table, calibrate to correct the error.

Span the current loop for maximum (20 mA) output at the selected weight (Parameter 64). • Enter the desired weight for 20 mA output. It is good practice to increase this number by one or two grads to keep the output within metering range.

  • Page 96: Setpoint Output Option Board

    HIGH SPEED DIGITAL WEIGHT INDICATORS SETPOINT OPTION BOARD There are a total of 6 Setpoints available on the M2000. Any of the 6 Setpoints can be assigned to any of the 3 channels. Once a Setpoint is assigned to a scale channel, it is not available for use by the other channels.

  • Page 97: Setpoint Control Mask

    TECHNICAL MANUAL SETPOINT SET-UP PARAMETERS SETPOINT CONTROL MASK - PARAMETER 57 Description: Controls how each of the 6 Setpoints will function. This is a 6 digit parameter with each digit representing one of the Setpoints. 654321 The left most digit represents Setpoint # 6 while the rightmost digit represents Setpoint # 1.

  • Page 98: Example: Assigning Setpoints

    HIGH SPEED DIGITAL WEIGHT INDICATORS EXAMPLE: ASSIGN SETPOINTS 1 & 2 TO ENERGIZE OUTPUT WHEN THE WEIGHT ON CHANNEL 1 IS LESS THAN THE SETPOINT VALUE. 1. Enter Calibration Mode for Scale Channel 1. 2. Enter the Setpoint Control Mask (Parameter 57). When Parameter 57 is entered for the first time, dashes will be shown across the display.

    HIGH SPEED DIGITAL WEIGHT INDICATORS REMOTE INPUT OPTION BOARD The isolated Remote Input board allows the M2000 to accept remote input switch control. CONNECTING THE REMOTE INPUT BOARD • Using the ribbon cable provided, connect J1 on the Remote Input board to J1 on the SMARTWIRE Bridge Interface board.
