3. INSTALLATION
AFWC-AFWD
a) Unpack the product.
b) Remove the transport locking screw above the platform.
c) Fix the column to the platform with the fitted screws
d) Fix the indicator to the column.
e) Level the platform by adjusting the adjustable feet until the bubble is in the centre of the level. The stability of the
platform is very important.
All the corners MUST REST IN A UNIFORM WAY. Carefully check that all feet fully rest on the ground and that the
platform, loaded on the corner, is not unstable (if a corner is not resting on the ground its relative foot is easier to turn).
Be sure the load cell is correctly connected to the indicator or an error will occur and the instrument setup will not
be accessible.
If a calibration has never been made, the indicator tries to do this automatically at the start-up (see also chap.
CONFIGURATION AND CALIBRATION in this manual).
3.1 CELL CONNECTION
Connect the female connector of the cable coming from the weighing module to the male connector placed on the rear of
the weight indicator, ad esso dedicato.

3.2 POWER SUPPLY AND START-UP
The indicator can be powered with a fitted 240 Vac external power adapter or just with the fitted battery.
NOTE: it is advisable to completely recharge the battery (12 hours) with the first installation of the instrument.
TO POWER the instrument through the 240 Vac mains put the AC/DC power plug in the appropriate socket on the back of
the scale and the power adapter in the 240 Vac mains socket.
TO TURN ON/TURN OFF the instrument press the ON/OFF key.

3.3 BATTERY POWERED
The weighing indicator can be operated from the battery if desired.
When the battery needs charging the symbol on the weight display will turn on. The battery should be charged
when the symbol is on. The scale will still operate for about 10 minutes after which it will automatically switch off to protect
the battery.
To charge the battery simply plug into the mains power. The scale does not need to be turned on.
The battery should be charged for 12 hours for full capacity.
You can find the “Charging”LED at the left of display to indicate the status of battery charging. When the scale is
plugged into the mains power the internal battery will be charged. If the LED is green the battery has a full charge. If it is
Red the battery is nearly discharged and yellow indicates the battery is being charged.
As the battery is used it may fail to hold a full charge. If the battery life becomes unacceptable then contact your distributor

4.1 FUNCTION OF THE KEYS
- Clears the displayed gross weight if it’s within the configured percentage (see section
7.8.1) of the total capacity.
- A secondary function of "Enter" key when setting parameters or other functions.
- If pressed for an instant it executes the semiautomatic tare;
- A secondary function of incrementing the active digit when setting a value for
parameters or other functions.
- If pressed for an instant it allows to execute the reference operation (see section 6.6)
and then execute the conversion from pieces to weight and vice versa.
- In the numeric or alphanumeric input, it selects the digit to be modified, from left to
right.
- It allows to convert in the configured secondary units of measure (see section 6.8).
- In the numeric or alphanumeric input, it selects the digit to be modified, from left to
right.
-It allows to enter the set-up environment (see section 7)
-In the numeric input phase, it quickly clears the present value.
- If pressed for an instant it adds the value to the accumulation memory if the
accumulation function is not automatic.

6. OPERATION
6.1 AUTOMATIC ZERO UPON START-UP
The indicator has an “auto zero at start-up” function: in other words it means that if at start-up a weight within the
configured percentage (see section 7.8.1) of the capacity is detected, it will be zeroed; if the weight is not within this
tolerance, the display shows “Err 4” and with a non approved instrument the present weight after a few instants, while
with an approved instrument “Err 4” is shown continuously (one has to remove the weight in excess and turn on again
the scale).
6.2 SCALE ZERO
If there are no objects on the scale and the display shows a weight different than 0, press the ZERO key to clear (the
“ZERO” symbol turns on). If the weight is greater than the programmed percentage (see section 7.8.1) in respect to
the capacity, the zeroing will have no effect.
The zero function may be disabled in the set-up environment; see section 7.8.1.
The scale has an automatic rezeroing function to account for minor drifting or accumulation of material on the platform
(see section 7.8.1). However you may need to press the ZERO/ENTER key to rezero the scale if small amounts of
weight are shown when the platform is empty.
6.3 TARE FUNCTION
Zero the scale by pressing the ZERO key if necessary. The zero symbol will be on.
Place a container on the platform, a value for its weight will be displayed.
Press the TARE key to tare the scale when the “stable” is light. The weight that was displayed is stored as the tare
value and that value is subtracted from the display, leaving zero on the display. The "NET" indicator will be on. As
product is added only the weight of the product will be shown. The scale could be tared a second time if another type
of product was to be added to the first one. Again only the weight that is added after taring will be displayed.
When the container is removed a negative value will be shown.
To remove the tare, unload the scale and press again TARE.
6.4 OVERLOAD MESSAGE
Please do not add item that is over the maximum capacity. When reading “—OL—“ and hear beeping sound,
remove the item on the platter to avoid damage to the load cell.
6.5 TOTALISATION OF THE WEIGHT
The scale can be set to accumulate manually the weight on the scale by pressing the PRINT/M+ key (see charter 7.7).
The weight displayed will be stored in memory and printed when the PRINT/M+ key is pressed and the weight is
stable.
The display will show "ACC 01" and then the total in memory for 2 seconds before returning to normal.
Remove the weight, allowing the scale to return to zero and put a second weight on. Press the PRINT/M+ key, the
display will show " ACC 02" and then the new total.
Continue until all weights have been added.
To view and print the totals in memory press PRINT/M+ key when current scale in zero status (Zero indicator on)
To clear the accumulated total weight, press the Fkey when show total values.
It’s possible to cancel the accumulated total also in the set-up environment (see section 7.3)

10
NOTE:
- The totalisation functions with a minimum weight of 20d.
- The maximum number of totalisations is 999 while the maximum total value which may be accumulated is
999999.
Once reached these limits, one should clear the total; by pressing PRINT/M+ the message “AdErr” will appear on
the display.
- The total values will be cleared when it’s turned off.
6.5.1 MANUAL OR AUTOMATIC TOTALIZATION
The operation of accumulation, normally done manually with key PRINT/M+, can be done automatically when the
weight is stable. In regards to the choice of the totalisation execution mode see section 7.7.
6.5.2 TOTALISATION IN UNLOADING
The accumulation operation, normally executed with a positive net weight can be executed with a negative net weight.
To enable the totalisation in unloading function see section 7.8.4.
PROCEDURE
1) Put the articles to be unloaded on the scale and wait for the weight to become stable.
2) Tare the weight with the TARE key.
3) Remove the weight which you want to unload and wait for the weight to become stable (one will see a negative
weight).
4) Press the PRINT/M+ key (manual totalisation): the LED display will show for an instant “totAL” along with an
acoustic signal; if a print format has been linked, a printout will be made.
5) Repeat the operations from point 2.
6.6 COUNTING PIECES
Through the reference function it’s possible to use the scale as a piece counter.
COUNTING PROCEDURE
The operations to be carried out are the following:
1) Place the empty container on the scale and press TARE to tare it.
2) Check that the zero is on the display and put the quantity of pieces chosen for the SAMPLE on the scale and
press SMPL.
3) The display suggests a REFERENCE QUANTITY. The possible options are: 10, 20, 50, 100, and 200.
4) Press TARE the number of times needed to reach the desired sample size.
5) Press SMPL; the display will indicate SAMPL and the indicator will calculate the Average Piece Weight (APW).
After a few instants the display will indicate the quantity selected put on the platform.
6) Add the rest of the items to count in the container and whose value will appear on the display.
7) Unload the scale; the APW will remain stored in memory for the next counting of similar pieces, without having to
repeat the REFERENCE operation.
8) By pressing the SMPL key one switches from the display of the number of pieces to the display of the average
piece weight and of the net weight.
9) To cancel or to carry out a new reference operation, press the Fkey and repeat the operations as describe in
point 2).
NOTE: The weight must be greater than 20 divisions to execute the reference.
6.7 CHECKING QUANTITIES BY WEIGHT
The scale is fitted with the quantity check function with 2 weight thresholds. An acoustic alarm and three reference
symbols on the display are enabled on the basis of the set thresholds and the weighing result.
6.7.1 SETTING OF THE WEIGHT THRESHOLDS
See section 7.2.
