The M1100e Scale
About the Scale
The M1100e is an easy to operate, general-purpose scale. The stainless
steel enclosure is water-resistant (IP67 / IP69K) and easy to clean. The
scale is available in two basic versions:
•An mains powered (110-230VAC) M1100e indicator with wall
mounting kit connected to either PL3000 or PL4200 platform (30kg
or 60kg).
•An battery powered (12-24VDC) M1100e indicator with wall
mounting kit connected to either PL3000 or PL4200 platform (30kg
or 60kg).
Marine and land based
M1100e scales Both models are available either as motion compensated marine scales
designed specially for use on board fishing vessels or as land based scales.
Both models can be used with weighing platforms of various sizes.
See “Appendix D ⎯Technical Specifications” on page 29 for more details
on the different models.
This user’s guide applies to the marine scale (M1100e-U3) and the land
based scale (M1100e-C3). Except for the marine calibration procedure
(see page 14), both types are operated in exactly the same way.
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.
User’s Guide The M1100e Scale •5

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.
Default Settings
On delivery the M1100e scale has the following default settings:1
•Zero tracking ON
•Automatic recording OFF
Communication
The following communication options are available for the M1100e
scale:
•RS-232. The M1100e 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.
1See “Setup Mode Commands” on page 20 for detailed information on how to change these settings.
6 •The M1100e Scale M1100e, U3 & C3-1.00

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 M1100e. 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.
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 M1100e. 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.
•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.
User’s Guide The M1100e Scale •7

•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 (for example 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.

used for entering commands and for confirming new settings.
Tare Key
Figure 9 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.
Zero Key
Figure 10 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.3
The operating zero is the reference point for all weighings, and therefore a
correct operating zero is necessary to ensure accurate weighing results.
3If automatic zero tracking is set (by activating a software switch, see p. 20), the scale will automatically track small
variations in the zero point. The maximum tracking rate is 0.5 divisions per second.

12 •The M1100e Scale M1100e, U3 & C3-1.00

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 to the M1100e 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 Display.
The scale then sets the initial zero (the message appears on the
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
Initial start of the scale
1 Plug in the scale.
2 The scale is now ready for simple weighing.
User’s Guide Basic Operation •13

Marine Calibration
The motion compensation of the M1100e 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 harbor.
Figure 11 Calibration message
The scale must be calibrated at initial start-up.
The scale must also be calibrated
•when the scale is unstable without the weighing platform being
touched.
•when the displayed weight is inaccurate, even when the scale has a
correct zero.
•when the scale is unable to assume the initial zero point, even with an
empty platform.
Tip
•It is a good maintenance rule to check the calibration
routinely by placing a weight on the weighing platform to
verify that the Weight Display shows a steady and accurate
weight.
To calibrate the scale
1 Make sure the platform is empty.
2 Press the MENU and ZERO keys simultaneously to put
the scale in Cal Mode.
The Weight Display shows: for a short time and then
the Weight Display shows:
3 Wait until the scale asks for a reference weight.
The Weight Display shows for example: 4
4 Place the reference weight on the platform.
5 Press the PRINT key to start the calibration.
The Weight Display shows while the scale performs
the calibration.
6 When the calibration is completed, the message
(where is a number between 0 and 99) appears on the
Weight Display.
Values above 25 indicate a poor calibration. In that case you
must repeat steps 1 to 4 above.
4The unit and weight displayed in this message varies with the size of the scale’s weighing platform.
14 •Basic Operation M1100e, U3 & C3-1.00

Note: The message appears when a marine scale
has been calibrated without the platform being in motion.
7 Remove the reference weight from the platform.
8 The Weight Display returns to zero and the scale is now
ready for use.
Functions
The following sections are an overview of the basic M1100e functions
the user should be familiar with:
•the Tare function
•the Zero function
•recording a weight, manually and automatically
Tare
To enter Tare
1 Place a tray (the tare weight) on the platform, and press the
TARE key .
2 The NET indicator lights up to show that a tare is in use, and
the Weight Display shows zero.
3 Subsequently, the NET weight on the platform is shown on
the Weight Display.
If tare is used, check the tare from time to time:
♦Place a tray on the platform, and notice if the Weight Display returns
to zero. If not, tare the scale again by pressing the TARE key .
To remove Tare
1 Empty the platform.
2 Press the TARE key .
The Net indicator is turned off.
Direct sale to the public Note: In some market areas the scale’s tare function may be protected with
a software switch.5This 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.
5According to standard regulations on conditions for direct sale to the public.
User’s Guide Basic Operation •15

Zero
To take a new operational zero point
1 Remove any weight from the platform.
2 Press the ZERO key .
The Zero indicator lights up.
Tip
•If the ZERO key does not function, you may have to take
a new initial zero by turning the power off and then on again,
or by pressing the arrow, the MENU and ZERO
keys simultaneously. (See “Zero Key” on page 11 for more
details on the Zero function.)
Recording Weights
You may want to record a weight that is positive and stable (Steady). The
recording is not stored in the scale itself, but is sent via the scale’s
communication port to a remote PC or a label printer.
There are two ways of recording the weight on the platform, manual or
automatic.
To record a weight manually
1 Watch the Steady indicator.
2 When the indicator light up, press the PRINT key to
record.
3 The message (Recording in progress) appears on the
Display as long as the recording is in progress.
4 If you try to record the same weight again (double
recording), a flashing appears on the display.
Press the MENU key to remove the message.
This message ( - Invalid recording attempt) also appears, if you try to
record an unstable or out-of-range weight.
To record a weight automatically
1 Enable this option by turning on the application switch
(see page 20).
2 The scale will automatically record the last stable weight on
the platform when you remove the weight from the platform.
