M2000D SYSTEM INTRODUCTION
GENERAL OVERVIEW
A M2000D weighing system consists of an indicator connected remotelly to one or two
DLC remote digital intelligent load cell terminal boxes, supporting up to 16 load cells.
A digital M2000D scale system provides for a high level of data integrity between the
scale platform and indicator for up to a 1000 feet apart. Because the analog scale data is
converted to digital data inside the remote DLC slave and send, as digital data to the
indicator, there is no data degradation across long cable runs. The digital system has a high
level of resistance to RFI /EMI interference, as required by industrial installations.
The M2000D system consists of an indicator and one or two DLC slave units. The DLC
slaves consist of 8 load cells per DLC. The digital system has no AD converters inside the
indicator itself. The M2000D supports 3 scale channels and calibration commands allow
the user to assign any or all of the load cells on the DLCs to a particular scale. A scale
assignment might consist of either a hopper or sectional scale configuration. These hopper
/ sectional scale groupings are then allocated to the 3 scales provided for by the M2000D
indicator – see Figure 1 for more detail.
MAIN FEATURES

TYPES OFSCALE SYSTEMS SUPPORTED
The M2000D targets two main types of industry scales, hopper and sectional scales.
Hopper scales consist of 2, 3 or 4 cells. In a hopper system each cell is usually referred to
as a corner. Each corner represents a load cell channel on the DLC slave. A hopper scale
can be assigned to any of the 3 scale channels of the M2000D indicator.
The service personnel have the ability to perform corner corrections (field corrections)
during calibration to compensate for small non-linear offsets in load cell values.
No access to the junction boxes are required to setup the system. All load cell corrections
are done in software as part of a calibration setup, from the M2000D indicator keyboard.
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. The service personnel have the ability to perform
corrections on a section by section basis or even on a corner basis if required.
DLC CHANNEL ALLOCATION
There can be a total of 2 DLC slaves in a digital system, referred to as the (P)rimary and
(S)econdary DLC slaves. The status LED on each slave indicates whether it is the
primary or secondary slave. Please consult the section on general diagnostics for more
information on the status LEDs .
The slaves are configured as (P)rimary or (S)econdary slave using the ID select jumper on
the DLC terminal box respectively.
The slaves are labeled as outlined in Figure 2. If the DLC board is set to be a secondary
slave, then the load cell channel numbering will be assigned as (S)econdary 1-8, and
(P)rimary 1-8 if the slave was configured for the primary slave. As outlined in Figure 2,
the analog to digital converter terminals are refered to as cells. Each cell will represent a
corner as part of a scale allocation. The allocation process of a scale that involves
multiple load cells are automatically assigned to unallocated cell terminals. The user does
not have to manually select and allocate cells for a scale setup.

Figure 2: Remote DLC slave Corner & Section grouping
The following restrictions apply to allocating cells for hopper or sectional scales:
qHopper 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.
qSectional Scales
A scale that uses sections will function in such a way that sections must be paired
together, across from each other as outlined in Figure 2. Two DLCs may be used for a
sectional scale allocation. Sections are allowed to span across DLC slaves. For
instance, the user might apply all 16 cells as a sectional scale which will provide 4
sections on the Primary DLC and 4 sections on the Secondary DLC, etc.

SCALE SETUP USER INTERFACE
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.
The following keys are assigned special function modes during calibration. The [ON/OFF]
key does not allow power down during calibration. This key is used to select the type of
information to be displayed as outlined below.
The [ON/OFF] key is used to select between graduated counts Œ, raw counts •(currently
displayed) or status information Ž. The status information shows the user what type of
scale was allocated, how many load cells are involved and to which terminal block they are
assigned. The status information window also shows the current load cell that is selected as
part of the calibration process.
The tare key is also assigned a special function and is used to select the current corner or
section. Most allocation calibration commands pertain to the currently selected load cell as
selected using the [TARE] key. As an example - assume a 4-corner hopper scale assigned
on the primary DLC as shown below. Using the [TARE] key, we can scroll and check one
corner at a time and also the sum total of the individual corners in terms of raw counts or
graduated counts:
If no load cells were allocated to a particular scale, or if an invalid scale allocation exists,
the following window will be displayed on the LED display:

GENERAL INSTALLATION GUIDE
INTRODUCTION AND OVERVIEW
The following information provides a general guide to a successful installation. Please
review these instructions before installing your unit.
High voltages may exist inside the enclosure. To prevent the risk of electrical shock, please
unplug the indicator when opening the enclosure. Installation and servicing of the M2000D
system should be performed only by qualified service personnel.
Complete the wiring of the external devices before connecting the indicator. Wiring should
comply with local area electrical codes. Wherever possible cables should be in conduit or
be otherwise protected from physical damage. Devices mounted outside should be
mounted in suitable enclosures away from direct sunlight. Once the external wiring is
completed, connect the indicator to the remote devices. Use the strain relief fittings
provided to route the cables in the indicator.
POWER SUPPLY CONNECTION
The M2000D indicator requires a regulated input with an external source of 10-35 VDC. A
120VAC to 12 VDC adapter is supplied with the indicator. Please pay close attention to
polarity of the power cord. It is important to note that in very noisy industrial
environments, power-conditioning filters would be a requirement to ensure a fail-safe
operation under all conditions. Indicators should not share AC power with electrical
motors and switchgear. Consult with the site engineer for clean AC power.
qLine filters and surge protection for minor static environments
qConstant voltage transformer for typical industrial installations
qUPS 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.
NOTE: The M2000D do not include an [ON/OFF] switch. The [ON/OFF] key does
not connect /disconnect the line voltage. The key “ awakens ” the M2000D from a
“sleep” mode.

INSTALLATION

m2000D technical manual

LOAD CELL CONNECTION
The main characteristic of a digital system is to prevent long analog load cell cable
connections between the load cell and the indicator. The installation strategy for a digital
system is to have the DLC junction box mounted as close as possible to the weighing
platform, to keep load cell cable runs between load cells and the DLC junction box as short
as possible, to eliminate contamination of load cell analog signals by RFI and EMI
interference.
Because the DLC junction box will be in close approximation to the load cells, losses in
load cell cabling will be kept to a minimum, and so the need for SENSE lines is
eliminated. For this reason, the DLC junction box do not include sense line terminals for
load cells. The load cell interface only requires EXCITATION and SIGNAL lines for a
total of 4 wires. Connecting a 6 conductor load cell cable to a DLC terminal recommends
the +SENSE and +EXCITATION conductors to be joined together and the –SENSE and –
EXCITATION conductors to be joined together respectively.
SERIAL PORT CONNECTIONS
Serial ports can be configured in the normal RS232 modes and to RS485 or RS422 multi
drop modes. Before connecting to the serial port, consideration should be given to the
communications protocol and to any remote requirements to prevent damaging serial ports.
The recommended cable to be used with serial communication is 20 to 28 AWG with a
braided or foil shield. The maximum recommended cable length is 15 meters or 50 feet.
However much longer connections are possible if using a properly shielded, low-
capacitance cable. The shield on a serial cable should only be connected to the M2000D
indicators shield terminal for the serial port in question. Do not connect the shield on both
ends of the cable – one end should be floating (not connected).
DLC COMMUNICATIONS CABLE CONNECTIONS
The DLC communications cable is the heart of the M2000D system. This cable conveys
high-speed digital packetized data between DLC slaves and the M2000D indicator. This
data is error corrected and although some packets might be rejected, the overall system
provides a zero loss data path over a maximum of a 1000 feet of cable. The DLC digital
cable provides optical isolation between the indicator and each of the remote DLC slaves.
The cable should have 4 conductors, one pair for power delivery and one pair for data
communications. 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. mm), with each pair of conductors foil shielded.

m2000D technical manual
Page 11
SYSTEM GROUNDING
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.
Surge protection components by themselves will not absorb all electrostatic discharge – it
should simply divert charges safely to an earth ground path. Because the indicator is
galvanically isolated from the remote DLC slaves, both ends should be grounded to a good
earth connection.
Normally the DLC terminal box will be mounted onto the steel chassis of the weigh
platform with a braided earth strap to the steel structure of the weighing platform. The steel
frame should be connected to a metal rod planted in the earth close by the weighing
platform. Earth straps should be at least 8 AWG thick and preferably no longer than 2 feet.
The earth strap should be kept as straight as possible - kinks in the earth straps induce
inductive resistances to the discharge path to earth ground.

SECTIONAL SCALE INSTALLATION GUIDE
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. Numbering should be incremental from one end of the
platform to the other end.
2. Once all load cells are connected, choose the scale to which you would like to allocate the
sectional scale, using commands 19, 29 or 39 to enter the calibration mode for the setup
procedure.
3. Note, if this is a new installation, normally the first command in calibration mode before
allocating the load cells, is to clear all existing allocations using calibration command 500, else
use commands 501,502 or 503 respectively
4. You are now ready to execute the sectional scale allocation command 521. This command
requires you to enter the number of sections you would like to assign to the scale (a section
consists of two load cells referred to as corners) as outlined in Figure 2.
5. Once command 521 is executed, you can view the raw counts of the scale on a section by
section basis. Use the [ON/OFF] key to select raw counts, and then use the [TARE] key to
move incrementally from one section/corner to another. This is an initial test to see if all load
cells are responding.
6. Note, if this is a new installation, command 530 needs to be executed to clear any existing
corner correction factors that might be resident in the remote DLC slave – very important.
7. At this point (as an optional step), the user can use command 11 to set the desired AD range
value for all the converters associated with the scale, to optimize the resolution of the AD
converters. Each AD converter can produce 512 000 raw counts at full AD input range.
8. Press the [ON/OFF] key until you see graduated counts (prefixed by the letter C). Graduated
counts always represent the sum of all the corners/cells.
9. The scale is now ready to be dead loaded using command 12 (this might take about 3 to 5
seconds). Do not disturb the platform(s) while the process is in progress. If the graduated
counts do not display zero counts, repeat the process.
10. The scale is now ready to be spanned using command 13. Place a graduated weight of ±1/3 of
the scale capacity in the center of the scale (if practical) and execute command 13 to span the
scale.
11. You are now ready to do section/corner corrections where needed, moving a graduated weight
from the center of one section to another or to a corner of a section. Press the [ON/OFF] key
until you see graduated counts (prefixed by the letter C). Use the [TARE] key to select the
summed display of a section or a corner (post fixed with the letter C on the display) of interest.
12. Once the section/corner is selected, use command 532/531 (default 532) to adjust the
section/corner weight to the expected weight - if required. When using command 532 you must
type in a target weight - command 532 will automatically adjust the section/corner to the target
weight. When using command 531, you must use the [IN/OUT] keys to increase or decrease
the weight. Command 532 is normally the first method used to correct sections/corners. If the
results are not satisfactory, command 531 can be used for a final correction. If required, the
user may correct on a corner by corner basis.
13. Press the [ON/OFF] key until graduated counts are displayed (prefixed by the letter C).
14. If the results are not satisfactory, move back to step 10 and repeat.

NOTE: Saving calibration data on a regular basis using calibration command 99 is a
good calibration practice.

521 Assign a Sectional Scale: calibration command
This command allocates the number of sections specified as the parameter to allocate a
sectional scale for the current scale under calibration (a section consists of 2 corners –
each corner gets assigned to a cell on the DLC box). For example, if a 4 sectional scale
is required, 4 will be entered at the keypad.
It is the task of the indicator to find the number of sections to assign for a sectional scale.
Sections will always be assigned incrementally starting from the first section on the
primary DLC slave 1/2, 3/4, 5/6, 7/8 through to the secondary slave etc., as required. If the
user does not want a section to be assigned (due to damage of the cell in question) the
user should first disable the cells using calibration command 525 before assigning the
scale
The following examples illustrate how to interpret the assignment information displayed
on the LED display while in calibration mode for a sectional scale. Use the [ON/OFF] key
to select the status display window. Taking the example of a sectional scale with 4 sections
– the status information provides the following allocation information. It displays how
many sections were assigned to this scale, and to which terminals each corner of each
section is assigned to. The status information is displayed as follows:
NOTE: If the system could not find any allocation space on either the primary or secondary DLC, it
will return with an error message. If this is a new system and this is the first scale assignment, it is
recommended to first perform a command 500 to clear all existing scale allocation information (all scale
information will be lost). 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 sectional scale assigned consists of a total of 4 sections. This parameter indicates
the number of sections assigned to the sectional scale.
