The system stores information in the DC slaves as part of a calibration. The other type of scale targeted by the M2000D is the sectional scale as implemented in vehicle scales. A sectional scale consists of 2 or more sections, of which each section consists of two paired load cell channels.
Page 10
2000D technical manual The following restrictions apply to allocating cells for hopper or sectional scales: Hopper Scales Hopper scale corners can be grouped on a single DLC, they cannot be spread across two DLC terminal boxes. Hopper scales can be grouped from any of the cells on a particular DLC slave terminal box.
The indicator is calibrated using the numeric keypad. There are no potentiometers or switches to set. The M2000D consists, like its analog counterpart, of 3 scale channels. To enter calibration mode, type in the scale channel number 19, 29 or 39.

Constant voltage transformer for typical industrial installations UPS protection for highly unstable power sources In cases where the M2000D unit might be installed in a vehicle or truck, it is important to provide for power conditioning between the vehicle’s power plant and the indicator. Please consult with your factory representative for more detail.
The cable should provide a separate foil shield for each pair plus a drain wire to be connected to the M2000D shield terminal. Do not connect the shield on the other end of the cable to anything. The recommended cable to be used is type 22 AWG (0.32 sq.
The following information deals with grounding as it relates to lightning and electrostatic discharges to earth ground. The M2000D provides for surge protection, however in order for surge conditions to be diverted properly, a good earth ground path should be in place.

2000D technical manual ECTIONAL CALE NSTALLATION UIDE Sectional scale installations do allow sections across multiple DLC slaves. The following set of instructions is a general guideline on how to allocate and calibrate sectional scales: 1. Install load cell cables to DLC slave units starting from the lowest cell number on the primary slave as labeled on the DLC boxes.
If the allocation was unsuccessful and other scales do exist that need to stay active, use Commands 501, 502 or 503 to clear only the current scale allocation information. Keep in mind that the M2000D indicator has 3 scales. The following examples illustrate how to interpret the assignment information displayed on the LED display while in calibration mode for a sectional scale.
2000D technical manual ECTIONAL XAMPLE Once the 4-section scale is allocated, the allocation information pertaining to each section of the sectional scale can be viewed by pressing the [TARE] key to scroll through all the sections and related corners. At any time we can look at the raw counts of a corner or section using the [ON/OFF] key.
We have two 8 channel DLC slaves for a total of 16 cells We have both Primary and Secondary DLC units connected to the M2000D We require a sectional scale with 6 sections ( total of 12 load cells)
Page 22
2000D technical manual Once we have allocated the sectional scale using command 521, we can use the [TARE] key in calibration mode to scroll through all the sections and related corners and use the [ON/OFF] key to observe the raw counts as required. The table below outlines and explains the status information as we scroll through the sections and corners using the [TARE] key.

2000D technical manual OPPER CALE NSTALLATION UIDE The following set of instructions is a general guideline on how to allocate and calibrate a hopper scale with no more than 4 load cells per hopper scaled. 1. Install load cell cables to DLC slave unit starting from cell 1 as labeled on the DLC slave. The first corner is always assigned to the cell with the lowest number.
For example - if a 4-corner hopper scale is required, 4 will be entered. A corner equates to a single cell on the DLC terminal box. The M2000D has 3 scales, to enter calibration mode for any one, use commands 19, 29 or 39.
2000D technical manual OPPER XAMPLE Once the 4-corner hopper scale is allocated (in calibration mode), the allocation information pertaining to each corner of the hopper scale can be viewed as follows by pressing the [TARE] key while in calibration mode: DLC (P) RIMARY DLC (S)
We have both Primary and Secondary DLC units connected to the indicator We require 3 hopper scales of 4 corners each The M2000D supports 3 scale channels. We must allocate a single hopper scale per scale channel. First we enter calibration mode for scale 1 by executing command 19, and after entering a password we allocate the first hopper scale using calibration command 520.
Page 28
2000D technical manual The following information can be viewed by entering calibration mode for each of the 3 scales respectively, and using the [TARE] key to scroll through the status information.

GENERAL DLC COMMANDS This command will reset and invalidate the current calibrated scale. The M2000D has 3 scales, to enter calibration mode for any one, use commands 19, 29 or 39. All information will be erased. This command is typically used for a new installation to clear any existing scale allocations to scale 1.
2000D technical manual DLC Load Cell Masking: calibration command The purpose of this command is to disable/enable cell channels to be allocated to a scale. This is an advanced feature, for normal scale allocations using commands 520/521 this command would not be necessary. This command is of use where a cell inside a DLC box is not operational or for a custom setup as required.
2000D technical manual Reset Corner Field adjustment entries: calibration command Field adjustment entries are the corner span corrections applied to corners during calibration, these entries would be cleared for new scale installations. Normally command 530 is performed directly after a scale was allocated using commands 520 or 521. This command only affects the selected scale under calibration.
2000D technical manual Corner / Section Manual Span Adjustment: calibration command This command allows the field personnel to adjust for small linearity discrepancies on a corner or section basis for a hopper or sectional scales. This command will act on the currently selected corner or section as outlined in the status display.
2000D technical manual Auto Corner Span Adjustment: calibration command This command allows the field personnel to adjust for small linearity discrepancies on a corner or section basis for a hopper or sectional scales. This command serves the same purpose as command 531 but instead of adjusting weight in a manual way, we simply type in the weight and the system will automatically span the selected corner/section to the target weight.
2000D technical manual DLC communications Error Counter: Calibration command This command is accessible from within or outside calibration mode. This command displays the number of aborted packets on the DLC communications line in real time. If this error count seems to increase abnormally high over a short period of time, it may indicate a noisy communications path or a general communications hardware failure.
This command prepares the indicator for a software upgrade to one of the remote DLC slave units. The software is downloaded via the M2000D indicator to one of the DLC slave units using the M2000 download software. For a DLC slave to be upgraded, it must be registered with the system –...
2000D technical manual DLC Set AD Range For Active Corner: calibration command This command is similar to calibration command 11 but has some distinctions. Command 558 will change the currently displayed corner/section or scale as a whole, depending on which corner the user scrolled to in calibration mode. Use the [TARE] key to scroll to the corner in question while in calibration mode –...
2000D technical manual Restore System Setup From DLC slave: calibration command This command is a calibration command. It will restore a previous backup from any one of the two DLC slaves to the master indicator. This command goes hand in hand with calibration command 591 –...
It is important to note that the backup will be generated from the last saved calibration and action table information as stored in the M2000D indicator. The user should first exit calibration mode to make sure that the information is saved to backup memory.

2000D technical manual Query Active DLC Cells on Slaves: calibration command This command is a calibration command. This command provides a means of first obtaining the current active cells per DLC slave, and secondly providing the option of changing the number of active AD converters per slave. If the user does not know the number of active cells per slave, the user may simply count the number of installed load cell connectors on the DLC slave.
2000D technical manual Scale Status/Diagnostics Information: non-calibration command This command displays the status information pertaining to the currently selected scale. This is a non-calibration command executed outside of calibration mode. First select the scale for which status information is desired from, by using 1, 2 or 3 followed by [PRINT/SELECT].
2000D technical manual DLC Slave Line Status: non-calibration command This command can be executed in or outside of calibration mode. This command will indicate to the user how many slaves were found to be online. The results can be interpreted as follows: 0 –...
