Getting Started

Connecting the Weighing Platform

Connection of an analog Minebea Intec MAPP or MAPS platform or of a commercially

available strain-gauge load cell is described in the following.

! The load cell should be connected only by a trained and authorized Minebea Intec tech-

nician. Any installation work that does not conform to the instructions in this manual

will result in forfeiture of all claims under the manufacturer’s warranty.

! Disconnect the equipment from power (unplug from the wall socket) before beginning

any installation work.

§ Set up the weighing platform (see the operating instructions for the weighing platform)

§ Lay the cable for connecting the weighing platform to the display and control unit

§ Open the Signum display and control unit:

remove the four cap nuts from the front panel and remove the panel.

§ Connect cable from the weighing platform to the display and control unit

Note:

The cable gland is installed at the factory. Please use extreme caution when performing

any work on the equipment that affects this cable gland.

Use a torque wrench and tighten the cable gland to 5 Nm.

§ Prepare and install the cable as follows.

– Guide the cable through the cable gland.

– Close and tighten the cable gland in accordance with the applicable regulations.

– Remove the casing from a section of the cable end (see illustration). The shield (1) must

have contact with the clamps (2).

– Expose approximately 15 cm (4 inches) of the wires (3) for connection to the terminals.

– Guide the cable through the cable gland.

– It is important to make sure that the shield is in contact with the clamps, because the

cable is grounded by the shield.

§ Install the weighing platform cable as follows:

– Remove the casing from a section of the cable end. Expose approximately 5 cm (2 inches)

of the isolated wires for installation.

– Remove the casing from approximately 1 cm (1/2 inch) of the wires and attach ferrules to

the wire ends.

– Fit the ferrite ring over all wires.

§ Check the voltage rating and the plug design.

$ The display and control unit is powered through the pre-installed power cord.

The power supply is built into display and control unit, which can be operated with

a supply voltage of 100 V to 240 V.

Make sure that the voltage rating printed on the manufacturer’s ID label is identical

to that of your local line voltage. If the voltage specified on the label or the plug design

of the power cord do not match the rating or standard you use, please contact your

Minebea Intec office or dealer.

The power connection must be made in accordance with the regulations applicable in

your country.

The device (protection class 1) must be plugged into a properly installed wall outlet

which has a protective grounding conductor (PE) and a fuse with maximum 16A.

The power plug or other suitable device for disconnecting the power must be easily

accessible.

Configuring the

Analog/Digital Converter

Purpose

To adapt the parameters of the analog/

digital converter to the connected load

cell or weighing platform. Once these

parameters have been configured, the

A/D converter in conjunction with

the load cell is defined as a weighing

instrument.

Notes on Settings

– The A/D converter can be configured

only with the menu access switch

open (see “Selecting the Configuration

Mode”). Make sure you close the menu

access switch following A/D converter

(ADC) configuration; otherwise, the

“overload” (H) and “underload” (L) error

codes are not shown.

– To enable ADC configuration, activate

the service mode (see “Service Mode”),

open the Setup menu, open the COM-

SPEC submenu, and select ADC-CON.

– Enter the maximum capacity (max. cap.)

in a suitable weight unit, without deci-

mal places (the rounding function will

truncate any decimal places).

! If you return to the highest menu level

without selecting the SAVE menu item

to save changes, all changes made up

to that point are discarded.

– The menu-reset function (“Restore

Factory Settings”) does not affect

settings for ADC configuration.

! Note:

Once the ADC configuration has been

locked (menu access switch closed), the

display and control unit can no longer

be used to influence weighing results.

The scope of functions available in the

weighing instrument is defined by the

A/D converter. Weighing functions that

can be activated include: read weight

value, tare, calibrate/adjust, read tare

value, save/delete tare input

Descriptions of Menu Items

for A/D Converter Configuration

Standard or Verified Configuration

(Menu Items: STAND. / VERIF.)

Before configuring the A/D converter,

you must define whether the weighing

platform is to be used in “standard”

mode or “verified” mode (verified for

use in legal metrology).

– Standard mode: STAND.

– Verified mode: VERIF.

Accuracy Class (Menu Item: CLASS)

Shown only for configuration in

“verified” mode.

Only menu items 3 and 4 (accuracy

class l/m) are accessible. If the

desired menu item is not marked with

a circle (o) indicating it is already active,

press ) repeatedly until this menu

item is activated.

Selecting the Weighing Range (Menu

Item: RANGES)

This setting defines whether the RANGE

1, RANGE 2 and RANGE 3 menu items

for further configuration steps are

shown or hidden.

– Single-range mode (SINGLE):

The entire weighing range is divided

into scale intervals on the basis of the

lowest interval d and the maximum

load. Readability is equal to scale inter-

val d (see below).

– Multi-interval mode (MULT.Int.):

The “Multi-interval” function divides

the weighing capacity into as many as

3 weighing ranges, each with a different

readability. The scale switches from

one range to the next automatically,

in accordance with the range limits

specified. Once the instrument has been

tared, the best possible resolution

(lowest display digit) is available even

when there is a load on the weighing

platform.

– Multiple-range mode (MULT.-R.):

A multiple-range scale has two or three

weighing ranges. When the maximum

capacity of a lower range is exceeded,

the scale switches to a higher range

(lower resolution). The scale can be

returned to the higher resolution only

after the scale has been unloaded.

Scale Interval d

The display digit, d, indicates the

resolution of the weighing instrument.

The display digit can be entered only in

increments of 1, 2, 5, 10, 20, 50, etc.

This menu item is not shown when

the “verified” configuration mode is

active. On verifiable or verified weighing

instruments (class l and m) scale

interval d is equal to verification scale

interval e.

Verification Scale Interval e

The verification scale interval e indi-

cates the resolution of the weighing

instrument in legal metrology. The scale

interval d can be entered only in incre-

ments of 1, 2, 5, 10, 20, 50, etc.

This menu item is not shown when

the “standard” configuration mode is

active.

Maximum Capacity (Max. Cap.)

The maximum capacity is the maxi-

mum load that may be placed on the

weighing instrument. If a heavier load

is placed on the platform, the display

shows “H.”

The scale intervals are calculated from

the maximum capacity and the scale

interval d. For example, a maximum

capacity of 15,000 kg with a smallest

scale interval d of 0.005 kg yields

3000 scale intervals.

Maximum readability:

15,000 display digits (not in legal

metrology).

In legal metrology, the number

of intervals must not exceed 3125 e;

for multi-interval scales, the limit is

3125 e per range.

8 Signum Option A15 Signum Option A15 9

Range 1, Range 2, Range 3

(RANGE 1, RANGE 2, RANGE 3):

Here you can enter the limits for each

of the weighing ranges. When a limit is

exceeded, the accuracy changes.

The following applies when entering

range limits:

Range 1 < range 2 < range 3 < max.

cap.

Thus the weighing capacity can be

divided into 4 ranges. The display reso-

lution changes in intervals of 1, 2, 5,

10, 20 etc. The lowest resolution is the

smallest scale interval d. Ranges you do

not require should be set to 0.

Available Weight Units (Menu Item:

UNITS)

The weight units available for use in

the normal weighing mode are selected

here. Available units are indicated by

a circle (o) on the display (more than

one can be selected).

When using the instrument in legal

metrology, make sure the selected unit

is permissible.

Saving Configuration Parameters

(Menu Item: SAVE)

Once you have selected all required

parameters, select the SAVE menu item

to store the settings.

Checking and Configuring the Equip-

ment for Use in Legal Metrology

A metrological ID tag is included with

the display and control unit.

Following ADC configuration, write

the metrological data on this tag for all

weighing ranges. Affix this tag below

the display and cover it with the water-

proof acetate overlay.

Entering Geographical

Data

Purpose

To perform an external adjustment of

the weighing instrument at a place of

adjustment that is not the same as the

place of installation (e.g., at the fac-

tory or on the dealer’s premises). If the

weighing instrument is adjusted at the

place of installation, it is not necessary

to enter the geographical data.

The sensitivity of a weighing instrument

can change depending on its place of

installation, because it is affected by

local gravity – or, more precisely, by

the acceleration of gravity. When the

geographical data is stored, the place of

installation can be changed following

external adjustment.

Calibration/adjustment of a weigh-

ing instrument is valid at the place of

installation and within a specific toler-

ance range around that location. With

3000 e, for example, the tolerance zone

is ±100 km of the geographical latitude,

and ±200 m of the elevation above sea

level.

The following exception applies in

Germany (“Zone D”):

If the latitude and altitude are set to

– 51.00° North and

– 513 meters above sea level,

the weighing instrument can be used

anywhere in Germany. The accelera-

tion of gravity applicable for Germany

(“Zone D”) is 9.810 m/s.

The geographical data stored in the

output device at the factory applies to

Germany (“Zone D”).

This setting is recommended for cali-

brating/adjusting weighing instruments

to be used within Germany. Entering

more precise geographical data will

increase the weighing instrument’s

precision, but will also restrict the toler-

ance zone.

Notes on Settings

– Geographical data can be entered only

in the service mode and only with the

menu access switch open.

– To enter geographical data, activate the

service mode (see “Service Mode”), open

the Setup menu, and select the COM-

SPEC submenu. Settings are configured

in the corresponding numeric menu

under menu item 1.20.

– Enter either the geographical latitude

in degrees (menu item 1.20.1) together

with the altitude above sea level (menu

item 1.20.2), or enter the acceleration

of gravity (menu item 1.20.3).

If the acceleration of gravity has been

entered, then this value takes prec-

edence over the latitude and altitude;

in this case, “99999.99” and “9999999”

are displayed for latitude and altitude,

respectively. If only altitude and lati-

tude are entered, “0000000” is shown

for the acceleration of gravity.

! If you return to the highest level of the

numeric menu without saving changes

(menu item 1.20.4), all changes made

up to that point are discarded.

Procedure

External Linearization

Notes on Settings

! External linearization can be performed

on verified weighing instruments only

when the menu access switch is open.

– The “external linearization” function

must be assigned to the � key

(menu item 1.9.6 or 1.9.7.).

! Following external linearization,

close the menu access switch and reset

the ) key (> 2 sec) to its previous

function (e.g., external calibration/

adjustment with user-defined weights)

under menu item 1.9.

Procedure

( Zero the weighing platform

� Start linearization

After approx. 2 seconds, you are prompted to place the first linearization weight

on the scale.

Place the prompted weight on the scale. After a brief pause, the difference between the

measured value and the true mass is displayed.

) Store the linearization weight (press ( to cancel).

You are prompted to place the second linearization weight on the scale.

Repeat the steps described above for all linearization weights.

After you store the last linearization weight, you are prompted to unload the weighing

instrument.

Calibration and Adjustment

Purpose

To check the accuracy of the weighing

instrument and perform any adjustment

required.

Calibration determines the difference

between the value displayed and the

actual weight on the platform.

Calibration does not entail making

any changes within the weighing

instrument.

The adjustment procedure actually

eliminates the difference between the

readout and the actual weight,

or reduces it to a level within the

permissible tolerance limits.

Features

Which of the following features are

available depends on the weighing

platform:

– External calibration/adjustment with

the default weight value or standard

weight (1.9.1) (not available on verified

scales)

– External calibration/adjustment with

a user-defined weight (1.9.3) (not

available on verified scales)

– Block the � key to prevent use of the

two functions described above (1.9.10)

– Calibrate first; then adjust automati-

cally (1.10.1) (not available on verified

instruments)

– Calibrate, then prompt for manual input

of adjustment command (1.10.2)

– Display of calibration prompt: flashing

W symbol (1.15.2).

– Block external calibration/adjustment

(1.16.2)

– Display altitude and geographical

latitude or acceleration of gravity after

CAL is shown at the beginning of

the calibration procedure (menu item

8.12.2). These values are shown only

if they have been entered in the service

menu and activated.

For each of these parameters, the term

is displayed first (“Altitud,” “Latitud” or

“Gravity”) for 1 second, and then the

corresponding value is displayed con-

tinuously until you press ).

Note

On verified weighing instruments,

the external calibration/adjustment

function is available only when the

menu access switch is in the “open”

position, which entails breaking the

verification seal. The equipment must

be re-verified after the seal has been

broken.

Calibration/Adjustment

without Weights

You can perform calibration/adjustment

without weights in the service mode

by entering the load cell specifications

(e.g., hopper weighing with known load

call specifications).

Notes on Settings

! Calibration/adjustment without

weights is not permitted on weighing

instruments used in legal metrology.

– Calibration/adjustment without weights

can only be performed in service mode,

and only when the menu access switch

is open.

– To enter the parameters required for

calibration/adjustment without weights,

activate the service mode (see “Service

Mode”), open the Setup menu and

select the COMSPEC submenu. Settings

are configured in the corresponding

numeric menu under menu item 1.19.

– The nominal capacity must be entered

in the weight unit selected under 1.7.x.

– Enter the nominal capacity of the load

cell(s) under menu item 1.19.1. If the

weighing instrument has more than one

load cell, multiply the nominal capacity

accordingly (e.g., 4 load cells with 50 kg

nominal capacity each yields a nominal

capacity of 200 kg).

– Enter the sensitivity of the load cell in

mV/V under menu item 1.19.3.

– If the weighing instrument has multiple

load cells, enter the individual values

for the load cells under 1.19.3 through
