The M1100 Scale
About the Scale
The M1100 is an easy to operate, general-purpose packing and grading
scale. The stainless steel enclosure is water-resistant (IP67) and easy to
clean. The scale is available in three basic versions:
• An M1100 indicator mounted on high pillars on a PLx platform
(xxxLx model). This version is also available with a battery option
(xxBLx model).
• An M1100 indicator mounted on short pillars on a PLx platform
(xxxSx model).
• An M1100 indicator with wall or table mountings (xxxNx model)
that can be connected to most weighing platforms with a strain gage
load cell.
Marine and land based
M1100 scales
All three models are available either as motion compensated marine scales
designed specially for use on board fishing vessels or as land based scales.
All models can be used with weighing platforms of various sizes. See
“Appendix D Technical Specifications” on page 43 for more details on
the different models.
Single or multiple range
weighing
The scale is available with a multiple range capability. The availability of
this option, however, depends on the platform type.
This user’s guide applies to the marine scale (M1100-U2) and the land
based scale (M1100-C2). Except for the marine calibration procedure
(see page 16), both types are operated in exactly the same way.
Packing Memories
Up to fifteen packing
memories and four units of
weight
The operator can program the scale with up to fifteen target weights in so-
called packing memories. Each target weight has its own definition of upper
and lower weight limits. Up to four different units of weight (kg, g, lb, or oz)
can be set for each target weight. The Config Display shows which of the
target weight memories, 1 to 15, is in use.
User’s Guide The M1100 Scale •5

Grading Memories
Five grading memories
with nine different grades
each
The scale also has five grading memories, each of which can be programmed
with 9 different grades. The grading memories can be used in three ways, for
normal, reverse, or positive grading (see “Grading Memory – Functions” on
page 23 for more details).
Multiple Range Weighing
Automatic change of
weighing ranges
The scale can be set up with a multiple range weighing option. With this
option the user can select to work with a fixed range or have the scale switch
automatically between the two ranges.
The automatic option is the scale’s default setting. The scale then switches
automatically from the lower range to the higher one when the weight on the
platform exceeds the maximum capacity of the lower range. See “Multiple
Range Operation” on page 21 for more details.
Initial Inspection
Prior to use, inspect the scale for damages incurred during shipment. If
the scale has been damaged, contact Marel hf. or your local Marel service
center immediately.
Installing the Scale
Before you apply power to the scale, check the following:
• Make sure that 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 (land based scales only).
• Use the built-in spirit level to level the scale platform (land based
scales only).
• On scales with separate indicator and platform, make sure the cables
between indicator and platform do not move during weighing. This
ensures optimum performance.
6 •The M1100 Scale M1100, U2 & C2-3.3

Default Settings
On delivery the M1100 scale has the following default settings:1
• Zero tracking ON
• Automatic tare OFF
• Automatic recording OFF
• All memories are set to zero except the following:
− Packing memory 1 is configured with upper and lower weight
limits
− Grading memory 1 is configured with lower grade limits for all
nine grades.2
Communication
The following communication options are available for the M1100 scale:
• CAN. The M1100 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.
• RS-232. The M1100 can communicate with external equipment
using RS-232. Weighing results can be printed on an external label
printer or the data can be transmitted to a PC for storing and further
processing.

User’s Guide The M1100 Scale •7

Cleaning
Note: A thorough daily rinse of the scale is very important to help
prevent corrosion and rust problems. Use clean cold water. Never rinse
with seawater.
• Clean the scale with detergents approved for use in the food industry.
Follow the manufacturer’s instructions for use.
• Do not use excessively strong solutions of detergent.
Base solutions corrode aluminum parts, for example load cells.
The use of chlorine can cause rust spots to appear on the stainless
steel.
• Do not use high-pressure jets on the M1100. Instead, use low water
pressure or pour water over by hand.
Detergents
The acidity of detergents used on Marel equipment should preferably be
pH 12-13.3
Strong base solutions are the main ingredients in most cleaning agents,
for example potassium hydroxide (KOH) or caustic soda (NaOH).
Because of its corrosive effects, caustic soda is not a desirable detergent
for the M1100. If possible, use detergent solutions with KOH instead.
Always use detergents according to the detergent manufacturer’s
instructions.
Do not use a detergent containing sodium hypochlorite for daily
cleaning. Sodium hypochlorite is a common ingredient in detergents, but
as it contains chlorine it should be used with great care because of
chlorine’s corrosive effect on stainless steel.
Daily cleaning
• Use high alkaline foaming detergent,ph 1% 12-13, for regular
daily cleaning. Do not use a detergent containing sodium
hypochlorite for daily cleaning. The foaming detergent must be
selected carefully and should contain some corrosion inhibitors
and preferably potassium hydroxide (KOH) instead of sodium
hydroxide (NaOH).
• Spray the detergent on all surface areas and leave to work for
approximately 20 minutes. Rinse the detergent off.
3Marel has developed the detergent Frima fip 6 in cooperation with Icelandic cleaning agents manufacturer Frigg hf.
Frima fip 6 is an alkaline foaming detergent suitable for use in all branches of the food industry and specially
designed to minimize the damaging effect of a harsh wash-down environment on Marel’s equipment.
8 •The M1100 Scale M1100, U2 & C2-3.3

• To kill any remaining bacteria, it is necessary to finish the daily
cleaning procedure by spraying a quarternary ammonium
solution over the area and onto surfaces (after drying), using a
300 ppm active ingredient.
• Before you resume processing the next morning or after breaks,
rinse the quarternary ammonium solution off surfaces in contact
with the raw material using clean water.
Disinfectants
When choosing a disinfecting agent, please note that chlorine corrodes
stainless steel. Chlorine is, however, an effective disinfectant, so
occasional use of chlorine may be necessary to control the growth of
microorganisms.
Marel recommends the following procedure:
• Use chlorine to disinfect once a week after performing the
regular cleaning with a high alkaline foaming detergent.
• Make sure the strength of chlorine does not exceed 200 ppm.
• Spray the disinfectant on surfaces and leave to work for
approximately 30 minutes.
• After disinfecting, carefully rinse the equipment.
• On days when chlorine is not used, use a disinfectant containing
quarter ammonium compounds instead.
• Make sure the strength of quarter ammonium compounds does
not exceed 750 ppm.
Note: Rotating different disinfectants (e. g. chlorine, peracid or acid-
anionic) in your hygiene program may ensure more effective sanitation.
As chlorine evaporates very quickly, its disinfecting effects will fade
soon after it is sprayed on the equipment. Letting chlorine stay on the
equipment will not improve the disinfecting effect, but only damage the
equipment. Quarter ammonium compounds are considerably more stable
and are active for a much longer time. Therefore, the benefit of leaving
them on the equipment for an extended period of time is much greater.
Training staff
It is important that new cleaning personnel receive proper training and
are made aware of areas on the machinery which are difficult to clean.

indicator consists of three parts, the Under, Accept, and Over indicators.
Figure 5 Weight Target indicator.
• The Accept indicator in the center lights up (green), if the weight on
the platform is within the set weight limits.
• The Under and Over indicators (red) on either side of the Accept
indicator light up if the weight is outside the weight limits.
The deviation is shown in steps, the step between two lights being
two scale divisions. A deviation of one division is indicated by two
simultaneous lights.
4Note! Due to local restrictions in some market areas and limitations caused by scale capacity, all units may not be
available.

Tare Key
Figure 13 TARE key.
The TARE key is used to set the tare. When you press this key with a weight
on the platform, that weight is used as a tare, and the Weight Display will
show a zero. The NET indicator lights up. The TARE key is also used to
remove tare.
Note: The TARE key cannot be used when Preset Tare is in operation.
Zero Key
Figure 14 ZERO key
The ZERO 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.5
The operating zero is the reference point for all weighings, and therefore a
correct operating zero is necessary to ensure accurate weighing results.
5If automatic zero tracking is set (by activating a software switch, see p. 34), the scale will automatically track small
variations in the zero point. The maximum tracking rate is 0.5 divisions per second.

Basic Operation
Applying Power to the Scale
The scale does not have an On/Off switch because it is preferable to keep
power on the scale at all times. Constant power generates heat that will
prevent moisture from condensing in the scale.
♦ Therefore, for initial start of the scale, simply plug the electrical cord
into the nearest suitable power outlet. For a battery operated scale,
attach the battery holder to the M1100 Indicator.
After power has been applied, the software version and the status of the
Cal/Con event counters appear briefly on the Weight Display and a light
test of the display is run. If the adjustment seal that prohibits modification
of calibration and configuration parameters has been applied, the
message appears briefly on the Config Display.
The scale then sets the initial zero (the message appears on the
Config Display), returns to Operating Mode, and is ready for use.
Note: The event counters change whenever the configuration is
modified and when the scale is calibrated. The counters can therefore be
used to check if an unauthorized calibration has taken place.
Operation
The M1100 scale is very easy to use. The scale has up to fifteen packing
memories, each of which can be programmed with the following
information:
• Unit of weight (kg, g, lb, oz. lb and oz can be disabled)
• Lower weight limits
• Upper weight limits
User’s Guide Basic Operation •15

The scale also has five grading memories, each with nine grades. The
memories can be programmed with:
• Unit of weight (kg, g, lb, oz)6
• Lower grade limit
• Grading method (normal, reverse, positive).
To change from packing to grading (and vice versa)
♦ Use the arrow keys to scroll through the memories to change from
packing to grading and vice versa.
The Packing and Grading indicators will light up to show which mode,
packing or grading, is currently active.
Initial start of the scale
1 Plug in the scale.
2 The scale is now ready for simple weighing.
3 If, however, you wish to use the packing or grading
memories, you must first
• enter the settings for the packing or grading memories
you intend to use, and then
• select the appropriate memory with the arrow keys.
See “Editing a Memory” on page 27 for more details.
Marine Calibration
The motion compensation of the M1100 marine scale must be calibrated
every once in a while to ensure the weighing results are accurate and
stable.
IMPORTANT! For optimum marine calibration results, always
calibrate the scale in the physical environment where it will be used for
weighing, i.e. at sea and not on land or in the shelter of harbour.
Figure 15 Calibration message
The scale must be calibrated at initial start-up. After that the scale submits a
warning, the message flashes in the Config Display, whenever a
calibration should be performed.
The scale must also be calibrated
• when the scale is unstable without the weighing platform being
touched.
