 TECHNICAL MANUAL

AUDIT TRAIL

The M2000 is equipped with a Category 1 Audit Trail system. The Audit Trail
has two counters:

Calibration Counter: Changing parameters that affect the calibration of

weight will increment the Calibration counter by 1.

Config. Counter: Changes to all other parameters (Configuration

parameters) will increment the Parameter counter by 1.

The counters will count from 000 to 999 before rolling over again. Changing
one or more parameters will increment the counter by 1 (One Counter tick per
Calibration session). Only an actual change of value to the Calibration or Set-
Up parameters will register to the Audit Trail.

Important Note: Because the Audit Trail becomes active at the

factory, the counters may not initially show 0, even when the M2000
is new out of the box.

IT IS EXTREMELY IMPORTANT THAT THE CORRECT TIME AND

DATE BE SET FOR THE AUDIT TRAIL TO BE ACCURATE. THE
AUDIT TRAIL IS PERMANENT AND CANNOT BE DISABLED OR
ERASED BY REMOVING THE INTERNAL BATTERY.

ACCESSING THE AUDIT TRAIL

The Audit Trail can only be accessed from Normal Weighing Mode.

1. Enter 1000 followed by the [PRINT/SELECT]. The message “Avdit” will

briefly be displayed.

avdit
1000P
2. Shortly after, the M2000 will display (in order) the date of the last change
made to the M2000’s calibration parameters, the Calibration (CAL) counter,
and the Configuration (CFG) counter.

03.10.31 Cal.001 Cfc.001

You may press the [CLEAR] key at any time to cancel this operation.

15
 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.

TESTING THE BATTERY - PARAMETER 244

Description: Used to take a measurement of the 3 Volt lithium battery. Voltage

levels are in mV and can be interpreted below.

In Calibration Mode, enter Parameter 244.

PARAMETER VALUE SETPOINT FUNCTION

3000 (3.0V) 3 Volts and above is considered good.
2700 (2.7V) 2.7 Volts and above is considered acceptable.
2.6 Volts or less is considered as low. Replace
2600 (2.6V)
battery.

REPLACING THE BATTERY

1. Remove the M2000’s back cover.

2. A coin-sized battery is located in a battery holder. (Upper left corner of the

M2000 PCB).

3. Use your fingers to grab each edge of the battery.

4. Gently pull on an angle removing the battery from the holder.

Replace the battery with a type RENATA CR2450N 3V 540mAh

lithium battery or equivalent. This battery should be available at
most electronics stores.

NEVER USE METAL OBJECTS SUCH AS SCREWDRIVERS TO

REMOVE THE BATTERY. THIS CAN RESULT IN PERSONAL
INJURY AND/OR A SHORT-CIRCUITING OF THE BATTERY
CAUSING DAMAGE TO THE INDICATOR.

16
 TECHNICAL MANUAL

INSTALLATION

17
 HIGH SPEED DIGITAL WEIGHT INDICATORS

POWER REQUIREMENTS

M2000 Indicators are precise electronic instruments that require clean, quality
power. Most M2000 models plug into 120 VAC external power. Inside the
enclosure, a 12 VDC power supply adaptor is utilized to run the indicator.

Slimline models connect to this power supply (included) externally.

It is important to note that in very noisy industrial environments,

power-conditioning filters would be a requirement to ensure 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.

POWER AIDS

The following items may prove useful for some installations:

• Line Filters and Surge Protectors: For installations in minor static

environments.

• Constant Voltage Transformers: For installations where the power circuit

is shared.

• True Uninterrupted Power Supply (UPS): For installations with highly

unstable power sources.

BATTERY POWER

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”
indication.

USE OF A BATTERY TO POWER THE M2000 IS NOT

RECOMMENDED. IF POSSIBLE, THE 12 VDC POWER SUPPLY
INCLUDED WITH THE INDICATOR SHOULD BE USED AT ALL
TIMES.

IN CASES WHERE THE M2000 IS INSTALLED IN A VEHICLE,

POWER CONDITIONING MUST BE PROVIDED. CONTACT THE
WESTERN SCALE CO. LTD. FACTORY FOR DETAILS.

18
 TECHNICAL MANUAL

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.

This includes:

• Systems incorporating conveyors

• Systems incorporating Shrink-wrappers

• Other devices that produce a lot of static

• Devices used to weigh static-charged materials (such as plastics)

should also be grounded in this fashion.

LINE NOISE

To reduce line noise, connect the Loadcell shield wire to the Ground
terminal, labeled “GND”, on the back of the M2000.
(See M2000A Wiring Terminals – Page 21)

PLEASE NOTE THAT THE GROUNDING REQUIREMENTS FOR

THE M2000D DIGITAL SYSTEM ARE MUCH MORE STRINGENT!
FOR MORE INFORMATION ABOUT THE M2000D AND
LIGHTNING PROTECTION, SEE THE M2000D TECHNICAL
MANUAL OR CONTACT THE WESTERN SCALE FACTORY.

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.

Main Filter: Used to stabilize the scale once a sustained weight is supplied
or the scale is at zero. The M2000 detects that a weight change
is “flattening out” and uses the Main Filter.

Faststep Filter: Used to dramatically improve the display response time for a
significant change in weight. When weight is being applied to
(or removed from) the scale, the M2000 detects that the weight
is changing rapidly and switches to the Fastep Filter, quickly
bringing the M2000 display to the target weight.

Without the Faststep Filter, the scale would be much slower in reaching the final
weight reading and returning to zero.

The default Filtering Settings should be appropriate for most

applications.

 TECHNICAL MANUAL

MAIN FILTER (DIGITAL AVERAGING) SETTING - PARAMETER 41

Description: Adjusts the level of filtering (averaging) performed to get the

final weight.

Increasing the filter value increases the number of weight samples

used for the average. At a time of sustained weight, the display
value will change very little.

Changing the filter value alters the settling time for the final weight.

Accepted Values: 1 to 255

PARAMETER VALUE RESULT OF FILTERING

1 Very little Main Filter. M2000 will be extremely fast,
but will likely not settle.
64 (default) Mid-range. Suitable for most applications.
255 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.

Default Value: 8 graduations.

IF THE FASTSTEP FILTER THRESHOLD VALUE IS TOO LOW,

WEIGHT READINGS WILL BE UNSTABLE REGARDLESS OF
THE MAIN FILTER SETTING!

51
 HIGH SPEED DIGITAL WEIGHT INDICATORS

EXAMPLE: SCALE CAPACITY OF 5000 lbs, 0.5 lb GRADUATIONS.

THE FASTEP FILTER THRESHOLD VALUE IS 8

GRADUATIONS (= 4 lb).

1. At zero, the scale is stable in Main Filter mode. A 200 lb man jumps on
the scale.

2. The rapid increase in weight causes the M2000 to go into Faststep mode,
bypassing the Main Filter and displaying a quick jump to 200lbs.

3. When the final weight is settling, the M2000 returns to Main Filter mode.
Slight movements (resulting in small weight changes) will be masked by
the Main Filter.

4. If a 2 lb weight (less than Threshold Value) is placed on the scale,

Faststep will not kick in and the weight change will be a little slower. The
time needed for this change is a function of Parameter 41.

5. If a 5 lb weight (greater than Threshold Value) is placed on the scale, the

M2000 will briefly enter Faststep Mode and the weight will change
quickly.

6. The man starts moving around. Every step exerts 10 lbs of force on the
scale. At the default values above, reading a weight would be virtually
impossible.

7. Changing the Main Filter Setting to average out these changes in weight
will be ineffective, since the 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.

9. Set the Faststep Filter Threshold value (Parameter 42) to 24, resulting in
a threshold of 12 lbs (24 x 0.5 lbs). Note this is greater than the weight of
the man’s steps.

10. At these values, the man’s steps will not trigger the M2000 to switch to
Faststep Filter Mode. The 10 lb steps will be filtered out by the Main Filter
and the weight display will be stabilized.

52
 TECHNICAL MANUAL

FASTSTEP FILTER SENSITIVITY - PARMETER 43

Description: The number of A/D weight samples in a row where the weight has
to change before the Faststep Filter kicks in.

This controls the M2000’s sensitivity to a weight change greater

than or equal to the Threshold Value (Parameter 42).

Increasing this parameter makes the Faststep Filter Threshold less

sensitive.

Default Value: 8 samples

Faststep Filter Sensitivity is used to filter out false triggers

induced by vibrations. This parameter is typically only used in
extremely demanding weighing applications.

EXAMPLE 2: THE MAN ON THE SCALE.

1. Using the previous example, it takes a sudden weight change of over

12 lbs for the M2000 to switch to Faststep Filter mode.

2. This weight change must be recorded for at least 8 consecutive

samples (default value) for Faststep to kick in.

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.

DISABLE FASTSTEP - PARAMETER 44

Description: This parameter disables the Faststep Filtering system altogether.

The M2000 will run with the Main Filter only. The response time for
the indicator becomes a function of Parameter 41.

PARAMETER VALUE FASTSTEP FILTERING

0 (default) Enabled.
1 Disabled. (Main Filter Only)

SOME CONTROL/BATCHING APPLICATIONS MAY REQUIRE

THAT FASTSTEP BE TURNED OFF.

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.

IF YOU HAVE A NON-LINEARITY ERROR OF MORE THAN 3

GRADUATIONS, A CLOSER MECHANICAL INSPECTION OF THE
SCALE AND ITS INSTALLATION IS REQUIRED.

CONNECTING A BARCODE SCANNER TO THE M2000

The M2000 allows for easy connection to a barcode

scanner. Combine your scanner and your scale to print
out accurate product/weight tickets.

Barcode scanners are intelligent devices that decipher

bar codes into normal ASCII strings. Most brands of
barcode scanner transmit an identical string that is
easily transmitted to the M2000.

WIRING THE BARCODE SCANNER TO THE M2000

• Scanners can only be connected to COM1.

• Establish the Barcode Scanner’s Pin-out. Use the M2000 Serial Wiring
Connections Table (Page 60) to determine the proper connections.

ENABLING THE BAR CODE SCANNER

• To enable Scanner Input on the M2000, Parameter 34 must be set to 100

(See Output String Format – Page 62).

M2000 - BARCODE SCANNER OVERVIEW

• The M2000 identifies that it has received a barcode string when it receives
a burst of characters from the scanner.

• Before transferring the received string to the string register, the M2000
waits a short time after it receives the last character. This allows the
M2000 to accept any string type not relying on a Carriage Return or Line
Feed to mark the end of the barcode transmission.

74
 TECHNICAL MANUAL

ASSIGNING A TICKET EVENT TO THE SCANNER - PARAMETER 95

Description: Print a specific ticket as soon as a barcode is scanned. The

ticket is executed as soon as the M2000 receives a scanner
string. Use Parameter 95 to assign the ticket number to the
scanner.

Default Value: 0 (Disabled).

The M2000 will not execute the ticket if there is motion on the
scale. The indicator will display ERR 36.

SCANNER HANDSHAKING MODE - PARAMETER 90

Description: The M2000 has 4 handshaking options.

PARAMETER VALUE FUNCTION

0 (default) No handshaking, No beep.
1 No handshaking with a beep.
2 Hardware handshaking with no beep.
3 Hardware handshaking with a beep.

The beep option will cause the M2000 to beep every time it
receives a bar code scan. Hardware handshaking disables the
scanner if there is motion on the scale. Hardware handshaking
must be enabled on the scanner, and is scanner specific. Most
applications will require a Parameter Value of 0 or 1.

PARAMETER 63 - CURRENT LOOP (GROSS OR NET MODE)

Description: Sets the current loop to operate in GROSS mode or NET mode.

GROSS: For most applications. 4 mA is output when the scale is at zero

(Centre of Zero LED illuminated).

NET: For applications with varying tare weights. The 4-20 mA board
will output only after a tare has been entered. 4 mA is out put
when the weight display shows zero, even though the true weight
on the scale is greater (NET LED illuminated).

PARAMETER VALUE CURRENT LOOP MODE

0 (default) GROSS mode
1 NET mode

PARAMETER 64 - CURRENT LOOP (SPAN)

Description: Spans the Current Loop Output to a custom weight entry. This is
the weight at which the Current Loop will output its highest level (20
mA).

The True Scale Capacity weight is typically selected. In some

applications (such as those utilizing NET mode), a weight less than
Scale Capacity is desired.

Enter the weight on the keypad, followed by the [PRINT/SELECT]

key.

If, for example, the scale capacity is 1000 kg, but Parameter 64 is
set to 500 kg, the Current Loop will reach 20mA at 500 kg.

IF, FOR ANY REASON, THE M2000 STOPS TRANSMITTING

COMMANDS TO THE 4-20 MA BOARD, THE CURRENT LOOP
OUTPUT WILL BE SET TO ZERO.

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. The Setpoint
Board connects to the SMARTWIRE BRIDGE INTERFACE and uses solid-state
relay modules to switch AC and DC loads.

CONNECTING THE SETPOINT BOARD

• Using the ribbon cable provided, connect J1 on the Setpoint board to J1

on the SMARTWIRE Bridge Interface board.

• Make sure the boards have adequate clearance between them.

• Make sure the SMARTWIRE Bridge Interface board has been wired
properly to the SMARTWIRE terminal.

FOR THE SETPOINT BOARD TO WORK, PARAMETER 59

MUST BE ENABLED!

IF, FOR ANY REASON, THE M2000 STOPS TRANSMITTING

COMMANDS TO THE SETPOINT BOARD, ALL OUTPUTS WILL
BE RESET TO “OFF”.

 TECHNICAL MANUAL

ENTERING SETPOINT VALUES

Parameters 51-56 are used to enter Setpoint values. Each of the 6 Setpoints
has its own weight compare registers. The values entered into these registers
will control the Setpoint relays. Setpoint values may be changed in Normal
Weighing Mode.

NOTE THE UNITS OF MEASUREMENT! TO ENTER A SETPOINT

VALUE IN KILOGRAMS, MAKE SURE THE M2000 IS
CURRENTLY WEIGHING IN KILOGRAMS.

PARAMETER 51: Enter weight for Setpoint 1, followed by [PRINT/SELECT].

PARAMETER 52: Enter weight for Setpoint 2, followed by [PRINT/SELECT].

PARAMETER 53: Enter weight for Setpoint 3, followed by [PRINT/SELECT].

PARAMETER 54: Enter weight for Setpoint 4, followed by [PRINT/SELECT].

PARAMETER 55: Enter weight for Setpoint 5, followed by [PRINT/SELECT].

PARAMETER 56: Enter weight for Setpoint 6, followed by [PRINT/SELECT].

SETPOINT HYSTERESIS ADJUSTMENTS - PARAMETER 58

Description: Hysteresis adjustments are used when vibrations in the scale

cause the Setpoints to falsely trigger. Increasing the Hysteresis
value increases the weight settling period for accepting a Setpoint
value.

Accepted Values: 6 digits are required (each digit represents each Setpoint as
in Parameter 57). Each digit can have a value of 0 to 9.

PARAMETER VALUE SETPOINT FUNCTION

Output action on the first occurrence of a weight
0 (default)
evaluation of the Setpoint.
1 Energize output when weight < Setpoint value.
2 Energize output when weight >= Setpoint value.
The Setpoint will only change after an evaluation has
9
occurred for 9 consecutive weight samples in a row.

The Parameter Value is internally multiplied by 10. A Hysteresis

factor of 3 will translate to 30 valid weight comparisons to the
Setpoint before an output action will take place.

CHARACTER ACTION
? Send Current Displayed Weight
1 Set to Channel 1 and send displayed weight
2 Set to Channel 2 and send displayed weight
3 Set to Channel 3 and send displayed weight
4 Set to Total Mode and send displayed weight
T Set Tare on current channel
C Clears stored Tare weight
G Switches to Gross mode
N Switch to Net mode if a Tare weight is stored
Z Zeroes indicator if within ZERO window

DF2500 COMMAND MODE 6

A fully interactive Command Set can be sent from a remote computer to operate
the indicator. This Command Mode has no checksum.

The maximum number of characters sent before the CR must not exceed 20.
The M2000 may fail to respond to the command if this number is exceeded.

Preceding the message with the STX insures the input buffer is cleared before
the next message. The indicator ignores LF and other control characters.

The following is a list of commands that can be executed:

COMMAND DATA REQ’D. FUNCTION

G None Set to GROSS mode and send string
N None Set to NET mode and send string
P None Tare scale & send NET string (0)
Tare Weight
T Set tare weight and send NET string
(left pad with spaces)
R None Recall tare weight
C None Clear tare weight & send GROSS string
? None Poll for weight (any mode)

 APPENDICES

The format of the command string sent to the indicator must be as follows:

POSITION CHARACTER CHARACTER VALUES

1 STX Start of text (02H)
2 D0 Data. These characters are filled by the
3 D1 numeric weight values used for the TARE and
4 D2 SETPOINT functions.
5 D3
6 D4
7 D5
8 D6
9 *Cmd The command character (see table below)
10 CR Carriage Return

The M2000 will reply with the DF2500 output string when it receives a valid
command. The returned data will reflect the command executed. Failure of the
indicator to respond with the correct mode or weight indicates that execution of
the command was not permitted.

Some commands may be inhibited (i.e. push to zero) and the return data will
reflect the indicator’s inability to complete these commands.

DF2500 COMMAND MODE 7

This mode is identical to DF2500 Command Mode 6 with the inclusion of an

‘Exclusive OR’ checksum. The checksum is included in both the SEND and
RECEIVE data strings as a two-character string immediately preceding the CR.

The checksum is calculated using an ‘Exclusive OR’ of all characters between

the STX and the first character of the checksum. The STX, checksum and CR
are not included in the checksum . The single byte calculated is converted into
two hexadecimal characters, each representing half of the byte. The most
significant 4 bits are sent first. The values are sent in hexadecimal format (0-F).
