Introduction
M2200 in General
The M2200 consists of an M2200 indicator with an LCD display and, if
used as a scale, of a separate load cell weighing platform. Depending on
the platform type, the M2200 scale is available with a dual range
weighing capability.
The M2200 is available in three models:
M2200-P02-xxxx-V1 packing scale, land-based•
•
•
M2200-M02-xxxx-V1 packing scale, marine
M2200-T02-xxxx-V1 registration terminal
The M2200 indicator is designed to run different user applications and a
variety of applications is available for use in various setups. Use of these
applications is described in separate manuals.
Default Settings
On delivery the M2200 scale has the following default settings1:
• Range mode AUTOMATIC
• Automatic tare NO
• Backlight always on NO
Communication
The following communication options are available for the M2200 scale:
• CAN. The M2200 is specially designed to operate in a networked
environment (CANopen). When the scale is connected to this type of
network, the network can supply the power.
The scale is a CAN Master and it can control up to two I/O modules.
1These settings can be changed via System Setup ÆConfiguration ÆOptions.
User’s Guide Introduction •3

• RS-232. The M2200 can communicate with external equipment
using RS-232 (serial connections). Weighing results can be printed
on an external label printer or the data can be transmitted to a PC for
storing and further processing.
• Ethernet. Application programs in the scale can communicate with
a computer network via Ethernet network.
Initial Inspection
Prior to use, inspect the M2200 for damages incurred during shipment. If
the scale/terminal has been damaged, contact your local Marel service
center immediately.
About This Manual
This manual is a collection of information on the M2200. Some of this
information is aimed directly at the M2200 operator, while other sections
are intended for technicians and software programmers.
The manual is divided into six parts:
General Introduction – this section, for all users.•
•
•

Capacity and Resolution: The tables below shows typical values of Max
and e when configuring a M2200 indicator.
Other values can be used, but a 3000 division
weighing range is often the maximum allowed
with regard to load cell specifications.
The indicator can be configured to operate as a
single or dual range scale that changes from a
low to a high range with the load on the platform.
Example:
First weighing range: Max1 = 3 kg, e = 1 g
(low weighing range, high resolution)
Second weighing range: Max2 = 6 kg, e = 2 g
(high weighing range, low resolution)

Operation
Before You Start
Before you apply power to the M2200 scale, check the following:
• Make sure there are no foreign objects that can interfere with the
platform’s movements.
• The platform must be empty when you power-on the scale.
• The scale must be properly mounted on a stable, level and non-
vibrating foundation.
• Use the built-in spirit level to level the scale platform.

Zero
The (ZERO/TARE) key is used to take a new operational zero
point provided the operating zero stays within ±2% of max weight from
the initial zero point.2
The operating zero is the reference point for all weighings, and therefore
a correct operating zero is necessary to ensure accurate weighing results.
The indicator illuminates when the scale is at zero.
2If automatic zero tracking is selected (Top Level Menu Æ4- System Setup ÆSystem ÆConfiguration Æ
Weighing Configuration ÆOptions ÆZero Tracking), the scale will automatically track small variations in the
zero point. The maximum tracking rate is 0.5 divisions per second.

To take a new operational zero point
1 Remove any weight from the platform.
2 Press
The Zero indicator ( ) appears on the display.
Tip
If zero can no longer be set using the key, you can
use the option Initial Zero Operation on the Scale Ops page
to take a new initial zero. The range of the initial zero can be
±10% of max weight calculated from the calibration zero
point.
The System Page
The System page (Top Level Menu Æ4-System Setup ÆSystem)

Creating Products
You can create a number of products, also called programs, that contain
your own packing parameters.
The following example shows how to create a product and specify the
necessary parameters for a stand-alone packing scale.
Note: M2200 applications use the packing parameters in different ways
and some applications do not use them at all.
To create a product

ID, name, and number for your product.

your application, for example:
− Nominal mode: Overweight
− Overweight: 0.100 kg
− Nominal weight: 2 kg
− Upper lock limit: 0.200 kg
− Lower lock limit: 0.200 kg
There are five different nominal modes available: Overweight,
Overweight %, Range, Steps, Any weight.
Each mode is explained in more detail in “Selecting a Nominal
Mode” on page 13.

weighing results automatically. There are four options available:
− record when the weight on the platform is removed from the
platform. This option is most commonly used for automatic
recording.
− record when the weight on the platform is increased
− record when the weight on the platform is decreased
− record when the weight on the platform changes and has
become steady.

Use this mode to pack to a fixed weight. The nominal weight is fixed. The
target weight is calculated as:
TW = FW + GF
Here you must specify upper and lower lock limits. The pack weight will be

Working with Tare
The scale has three tare functions:
Normal tare•
•
•
Automatic tare
Preset tare
Normal and automatic tare The first two work in a similar way, except that Automatic Tare
automatically compensates for slightly different weight of trays or boxes
which are placed on the platform.
This means that you can place different trays on the scale’s platform
without having to press every time you change trays – the
Automatic Tare function will do that for you.
Preset tare Preset Tare, however, is different in that it is the user himself who enters a
tare value of his own choice, instead of a weight detected by the scale.
This method can be useful in certain situations, for example in packing
systems where the weight of the packing material is known.
Normal Tare
To enter tare
Figure 8 Scale page, tare in use.
1 Place a tray (the tare weight) on the platform, and press
.
2 The NET indicator appears on the Scale page to show that a tare
is in use.
3 Subsequently, the NET weight on the platform is shown on the
Scale page.
To remove tare
1 Empty the platform.
2 Press .
The NET indicator is turned off.
User’s Guide Operation •15

Direct sale to the public
Note: In some market areas the scale’s tare function may be protected with
a software switch.3This changes the way you work with tare:
• You must remove tare (see above) before you can set a new tare value
that is lower than the current tare value.
Automatic Tare
To use Automatic tare
1 Check whether the Automatic Tare option is currently selected
on your scale. By default, this option is not selected.
2 From the Top Level Menu select 4-System Setup ÆSystem Æ
Configuration ÆOptions.
3 On the Options menu select Automatic Tare and press .
4 Enter YES to work with Automatic Tare and press several
times, until you return to the Scale page.
5 Place a tray (the tare weight) on the platform, and press
(normal tare, see above).
6 Remove the tray, and place a new tray on the platform.
7 If the second tray is within ±30% of the first tray, the weight
of this tray will be automatically tared and the weight
indicator on the Scale page will show zero.
When using automatic tare, you should check the tare from time to time:
♦ Place a tray on the platform, and notice if the weight indicator on the
Scale page returns to zero. If not, tare the scale again by pressing
.
Automatic tare is not available if the scale is configured for “direct sale to
the public”.
Note: The Automatic Tare function can compensate for up to 30%
variation in the tare.
The second tray you put on an empty platform will be tared automatically
if it is within ±30% of the weight set by the manual tare operation.
For this function to work it is important that the scale is stable and with
an empty platform before you place the second tray on the scale.
