2 Installation

2.1 Precautions

Before you install your VIVA scale, identify the best location for the equipment. The proper
environment enhances the operation and longevity of the scale. Keep in mind the following factors,
which might have a negative influence on the scale's operation:

 Vibration diminishes the scale’s ability to measure accurately. Excessive vibration from

equipment such as conveyors can cause inaccurate and non-repeatable readings.

 Be sure the scale is leveled properly.
 Air currents can also diminish a scales performance. Avoid placing the scale in front of or

directly under air vents.

 Other than items being weighed, keep the scale free from objects rubbing or pressing against

the platter.

2.2 Contents of Packaging

Package contents for all VIVA units include:

 VIVA scale base
 Stainless Steel Platter
 AC-DC power adapter
 Operation manual
 Display Cable
 Tower included and attachment hardware (The optional display may be packed separately)
 Base Bracket (weigh only version with round corner platter)

2.3 Setup

1. Open the box, carefully remove the packing material, take all items out of the carton.

2. Attach the display as described below, depending on which version of scale you ordered:

3. Put the platter on top of the VIVA scale base.

4. Connect the tower display cable to the scale.

5. Connect the power cord from the wall transformer to the scale base.

2.4 Power up sequence

Plug the adapter into a properly grounded AC power outlet. The scale will go through a series of
self-tests and then will proceed to normal operating mode. The power-up sequence is as follows:

1. All segments of the display characters are lit. This verifies operation of all segments;

2. The scale displays the country code and GEO code, software part number and revision.

3. The scale then captures zero and is ready for normal operation.

Note: Before switching on the VIVA scale, always make sure there is nothing on the platter.

2.5 Sealing

After installation is complete, legal-for-trade applications require sealing the
enclosure so the settings cannot be changed.

There are two kinds of sealing: lead wire and label.

The lead wire sealing sequence is as follows:

 Install special through-hole sealing screw.
 Tighten these two screws and run a wire seal through the holes in the heads

of the screws.

 Apply the seal.

The label sealing sequence

Security Sticker Ø 15mm, material Vinyl white 3690 E UL, color red, text color black.

There are two labels that used for sealing. The position for the sealing labels is shown below.

Available Capacity

9. Use the Tare key to select the weight capacity.

Note: 30kg and 60lb are above the load cell’s capacity and will not work.

10. Press the Zero key to accept.

11. The display will now show “- - - - - -“. This indicates the scale is ready to take a zero reading.
Be sure the platter is on the scale and the platter has nothing on it or anything touching it.

12. Press the Zero key to accept.

13. The display will count down from 5 to 0.

Note: If the scale is unable to capture a stable reading it will start the count over at 5.
The count down will not restart until there is a stable reading. Verify nothing is
touching or interfering with the scale.

14. The next step is to place weight on the scale. The
display will show a number that is illustrated in the chart
to the right and corresponds to the capacity that was
selected in Step 9. The display will start off showing
the 2/3 Load value. You can use the Tare key to
select the Full Load value. For instance, if you are
calibrating the scale for 15kg capacity, the scale would
display the 2/3 Load value of “10000”. This would

Capacity 2/3 Load Full Load

3kg 2000 3000
6kg 4000 6000

15kg 10000 15000

6lb 4000 6000
15lb 10000 15000
30lb 20000 30000

indicate to the scale you are going to use 2/3 of the capacity for the calibration. Place 10kg
on the scale and then press the Zero Key. If you selected “15000” to indicate full load, you
would place 15kg on the scale and then press the Zero Key.

15. The display will count down from 5 to 0.

Note: If the scale is unable to capture a stable reading it will start the count over at 5.
The count down will not restart until there is a stable reading. Verify nothing is
touching or interfering with the scale.

16. If the calibration is accepted, the display will show “GrP 3”. Press the Tare Key.

17. The display will show “Save”, press the Tare Key to select between “Save” and “Abort”.

18. Press the Zero Key to accept.

19. The scale will now save (or abort if you selected that in Step 17.) the calibration and cycle out
of the Service mode and return to normal weighing mode.

20. Verify the calibration was successful with the calibrated weight. If for some reason the
calibration was not successful, restart at Step 1.

21. If applicable, you should remove power from the scale and apply the appropriate calibration
seal.

22. Place the scale into service!

>T<

Used to return the scale to gross zero.

4.3 Cursors

Cursor Description

ZERO When weight is gross zero.

NET When tare is entered.

4.4 Operations

4.4.1 Weighing and Communication

Place the item to be weighed on the platter, the weight will be displayed.
Remote ASCII commands can control the scale through the provided RS232 port. Commands

include zero, tare, and other data functions depending on the protocol. See Section 6 for
available protocols and their descriptions.

4.4.2 Backlight function

Tare key.

VIVA is equipped with a backlight for the display. If ambient lighting conditions are not sufficient,
the backlight can be switched on to easily read the display.

To activate, Press and hold the Zero Key until a long beep is heard and the backlight turns on.
Use the same procedure to switch the backlight off or just remove power to the scale.

VIVA Service Manual

18

When the scale is not used for 1 minute, the backlight will automatically switch off. When weight
is placed on the platter or a key is pressed, the backlight will switch on again.

4.4.3 Re-zero Functions

There are two ways to re-zero the scale:

Power-up Zero

The scale will automatically capture zero when it is turned on. The power-up zero capture range
is +/-10% of the scale capacity. When the scale is turned on with a weight on the platter of more
than +/-10% of the capacity, the scale will not capture zero and the weight display will show
"-----". After removing the weight, the scale will capture "zero".

Pushbutton Zero

The Zero Key re-zeros the scale within the range of +/-2% of the scale capacity. To use this
function, the scale must be in the gross weighing mode (NET cursor must be off) and in a no
motion condition. When the weight on the platter is more then +/-2% of the scale capacity,
pressing neither the Zero Key nor a remote ASCII Zero command will be accepted.

4.4.4 Tare Function

METTLER TOLEDO

The Tare Key allows you to subtract weight from the platter for items like containers that will be
used to hold the item being weighed.

Place the empty container or wrapping material on the platter.
Press the Tare Key.
Place the item to be weighed in the container or on the wrapping material and onto the platter.
