Safety Information:

§ Please read these operating instructions

carefully before using your indicator to prevent damage to the equipment.

! Do not use this equipment in

hazardous areas.

! Use only standard cables that have

protective grounding conductors. The protective conductor must not be disconnected for any reason.

! Disconnect the indicator from power

before connecting or disconnecting peripheral devices.

! The indicator may be opened only

by trained service technicians.

! If you operate the equipment under

ambient conditions subject to higher safety standards, you must comply with the applicable installation regulations.

! If there is visible damage to the

equipment or power cord, unplug the equipment and make sure it cannot be used for the time being.

Installation:

– Proceed with extreme caution when

using pre-wired RS-232 connecting cables from other manufacturers, as the pin assignments may not be compatible with Sartorius equipment. Check all pin assignments against the cabling diagrams and disconnect any lines that are not assigned.

– Connect only Sartorius accessories and

options, as these are optimally designed for use with your Combics indicator. The operator shall be solely responsible for installation and testing of any modifications to Sartorius equipment, including connection of cables or equipment not supplied by Sartorius. Contact Sartorius for detailed operating specifications in accordance with the Standards for immunity to interference.

$ If you have any problems with your

Combics indicator, contact your local Sartorius customer service center.

IP Rating:

– CISL models are rated to IP44

(with Option L1: IP65); CIS models are rated to IP67.

– The IP65/IP67 protection rating is

ensured only if the rubber gasket is installed and all connections are fastened securely (including the caps on unused sockets). Weighing instruments must be installed and tested by a certified technician.

– If you install an interface port after

setting up your indicator, keep the protective cap in a safe place for future use. The cap protects the interface connector from vapors, moisture and dust or dirt.

Using the Equipment in Legal Metrology in the EU*:

– When the indicator is connected to a

weighing instrument and the resulting weighing instrument is to be verified, make sure to observe the applicable regulations regarding verification. When connecting a Sartorius weighing instrument, please observe the “Guide to Verification" on the enclosed CD and the permitted weighing range as listed in the Declaration of Conformity.

– EU legislation requires that a control

seal be affixed to the verified device. The control seal consists of a sticker with the “Sartorius" logo. This seal will be irreparably damaged if you attempt to remove it. If any of the verification seals are damaged, make sure to observe the national regulations and standards applicable in your country in such cases. In some countries, the verification will become null and void and the equipment must be re-verified.

Automatic Taring (Menu Item 3.7)

When menu item 3.7.2 is active, the first load placed on the weighing instrument that exceeds the specified minimum load is stored, at stability, in the tare memory. The weighing instrument returns to the initial state when the load is less than 50% of the minimum load.

Minimum Load for Automatic Taring and Automatic Printing (Menu Item 3.5)

You can choose from the following settings for the minimum load:

1 digit (no minimum load) 2 digits 5 digits 10 digits 20 digits 50 digits 100 digits 200 digits 500 digits 1000 digits

The “digits" here refer to the intervals in the connected weighing instrument. If the interval of the connected instrument is 1 g, for example, and 1000 digits are required, the minimum load is 1000 g (=1000 digits). If the interval of the connected instrument is 5 g and the same number of intervals is required as in the example above, the minimum load is 5000 g.

Once the load on the weighing instrument exceeds the specified minimum, the instrument is tared and/or a printout is generated, if the operating menu is configured for automatic taring (menu item 3.7.2) and/or automatic printing (menu item 7.13.2).

Automatic Printing (Menu Item 7.13)

When menu item 7.13.2 is active, the first weight value that exceeds the specified minimum load is printed. If the menu code for automatic taring is also active, the weighing instrument is only tared when the minimum load is exceeded; the value is not printed.

First Weighing Instrument Displayed (Combics 2 only)

You can define which weighing instrument shows the first weight value when you switch on the Combics, under utilit (menu item 8.9).

Entering Tare Weight using a Bar Code Scanner (Combics 1 plus and Combics 2 only)

You can enter the tare value of a container using a bar code scanner. To do this, the “Store value as tare" (tare) menu item must be selected under “Setup > Bar code" in the operating menu. In this case, the value is stored as the tare automatically, without pressing the t key. The contents of the tare memory are display in Info mode (press and hold w).

Entering ID Codes using a Bar Code Scanner (Combics 1 plus only)

You can use a bar code scanner to enter ID codes. To do this, the “Store value as ID1" (id1) menu item must be selected under “Setup > Bar code" in the operating menu. In this case, the value is stored as ID1 automatically, without pressing the g key. To store the second ID code, the h key must be pressed. To view the stored ID codes:

– Press I and g – Press I and h

Calibration and Adjustment

Purpose

The accuracy of weighing results must be carefully controlled. This is achieved through calibration and adjustment.

Perform calibration to determine the difference between the value displayed and the actual weight on the weighing instrument. 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 instrument:

– External calibration/adjustment with

the default weight value or standard weight (1.9.1) (not available on verified instruments)

– External calibration/adjustment with

a user-defined weight (1.9.3) (not available on verified instruments)

– Internal calibration/adjustment for

IS platform (1.9.4), WP2 only

– Block the ) key to prevent use of the

two functions described above (1.9.10)

– Calibrate first; then adjust automatically

(1.10.1) (not available on verified instruments)

– Calibrate, then prompt for manual input

of adjustment command (1.10.2)

– Calibration prompt: flashing W symbol

(1.15.2). If more than one weighing instrument is connected, the instrument number is also displayed.

– 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 continuously 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 (refer to the chapter entitled “Service"). The equipment must be reverified after the seal has been broken.

Counting Z

With the Counting application, you can determine the number of parts that each have approximately equal weight.

Features:

– Store the weight on the weighing

instrument as reference weight

– Enter reference weight using

a bar code scanner

– Enter tare weight using a bar code

scanner

– Automatic reference sample updating

(user-definable)

– Counting with two weighing

instruments

– Toggle the display between piece count

and weight by pressing w

– Info mode for display of average piece

weight and reference sample quantity by pressing w (> 2 sec)

Before the quantity on the weighing instrument can be calculated, the average piece weight must be entered in the application. There are 2 ways to do this with the Combics:

– By placing the number of parts defined

as the reference sample quantity on the weighing instrument and pressing O to store the average piece weight.

The reference sample quantity is shown in the numeric display, and can be changed by pressing r.

How the reference weight is calculated depends on the menu setting for resolution (3.9). Either the value is rounded off in accordance with the display resolution, or the display resolution is increased 10-fold (+1 decimal place) or 100-fold (+ 2 decimal places), or maximum internal resolution is applied.

– By entering the reference piece

weight (i.e., the weight of one piece) using a bar code scanner (menu setting: “Setup> Bar code > Store value as reference (ref)"). In this case, the value is stored as a reference automatically, without pressing the O key.

This value remains active in the reference memory until you delete it by pressing c, overwrite it or until you select a different application. It also remains in memory when you switch to a different application program, or switch off the Combics.

Storage Parameter

The reference weight is saved when the weighing instrument has stabilized. “Stability" is defined as the point at which fluctuation of a measured value lies within a defined tolerance range. The narrower the tolerance range, the more stable the weighing instrument is at “stability." This setting is also applied when you zero the weighing instrument. Under menu item 3.11 you can determine whether the value is saved “At stability" (normal tolerance range) or “At increased stability" (narrower tolerance range). If you select “At increased stability," the average piece weight stored will be more accurate and the results more reproducible, but the response time of the weighing instrument might be longer.

Minimum Load for Initialization

The minimum load for initialization is configured under menu item 3.6. If the load exceeds this limit, the weighing instrument can be initialized. If the load is too light, the following

will occur when you try to save a value: – The error code inf 29 is displayed – A warning signal is emitted

(double-beep) – The weighing instrument is not

initialized – The preset reference sample quantity

is stored

Reference Sample Updating

In the Application settings under 3.12, you can define whether the reference sample is updated automatically. Reference sample updating is performed automatically only when the following 6 criteria are met:

1. Menu item 3.12.3 is active

2. The current piece exceeds the original piece count by at least two

3. The current piece count is less than twice the original piece count (does not apply for the first update if the piece count is entered using a bar code scanner).

4. The current piece count is less than 100.

5. The internally calculated piece count (such as 17.24 pcs) differs by less than ± 0.3 pcs from the whole number (17 pcs in this example).

6. The weighing instrument is stable in accordance with the defined stability parameter.

When automatic reference sample updating is active, the AUTO symbol is displayed in addition to the Counting symbol (Z). When the reference sample has been updated,

OPT

is dis-

played below

AUTO

. During an updating operation, 0pt and the updated piece count are displayed briefly in the main display.

At the conclusion of reference sample updating, a beep is sounded and the new reference weight and reference sample quantity are stored. Activate the “Info" mode to view the reference values (press and hold w > 2 sec).

Counting with Two Weighing Instruments

You can use two weighing instruments simultaneously with the Counting application. When using two instruments, you can choose from the following operating modes:

– Counting with two equivalent weighing

instruments

– Counting with one reference weighing

instrument and one counting platform

Counting with Two Equivalent Weighing Instruments Use this mode when samples of widely varying weight are counted at one workstation. Count the lighter-weight pieces on one weighing instrument and the heavier pieces on another. When you press n to toggle from one weighing instrument to the other, the application is re-initialized. You can define which of the two weighing instruments is active in the display when the Combics is switched on (menu item 8.11). This is the first weighing instrument active when you switch on the Combics, regardless of the setting for automatic initialization of the Counting application.

Counting with One Reference Weighing Instrument and One Counting Platform In this mode, a high-resolution weighing instrument with a relatively low maximum capacity is used as a reference weighing instrument. The weighing platform is used for weighing heavier samples, and has a high capacity with a relatively low resolution. This way, you can both determine the reference sample quantity very precisely and count large amounts of parts, without requiring an expensive highresolution, high-capacity weighing platform. Specify which weighing instrument is the reference instrument under menu item 3.13. The system toggles automatically to the reference weighing instrument for initialization (Ref is displayed). Following initialization, the system toggles to the counting platform.

The system does not toggle automatically for automatic reference sample updating; the update is based on whichever instrument is active.

Neutral Measurement Z nm

When the Neutral Measurement application is selected, you can use your weighing instrument to measure the length, surface and volume of parts that have roughly the same specific weight. The

symbol is displayed as the weight

unit.

Features:

– Store the weight on the weighing

instrument as reference weight

– Enter reference weight using a bar code

scanner

– Enter tare weight using a bar code

scanner

– Toggle the display between weight

and calculated value by pressing w

– Info mode for display of reference

weight by pressing w (> 2 sec)

To calculate the result correctly, the average weight of a reference quantity must be known (in the example below, the reference is 1 meter of electrical cable). There are 2 ways to do this with the Combics:

– By placing the number of parts defined

for the reference value on the weighing instrument and pressing O to store the average piece weight.

The reference value is shown in the numeric display, and can be changed by pressing r.

– By entering the reference weight (i.e.,

the weight of one piece) using a bar code scanner (menu setting: “Setup> Bar code > Store value as reference (ref)"). In this case, the value is stored as a reference automatically, without pressing the O key.

This value remains active in the reference memory until you delete it by pressing c, overwrite it or until you select a different application. It also remains stored after you switch off the Combics.

Checkweighing O

When the Checkweighing application is selected, you can check whether sample weights correspond to a specified target weight; i.e., whether the weight on the weighing instrument is within a given tolerance range. The tolerance range is defined by upper and lower limits. The result is displayed in the main indicator, in the bar graph and by colorcoded LEDs.

Features:

– The target value can be taken over

as a weighed value from a weighing instrument, and the tolerance limits are defined as a perceptual deviation from the target value. The following percentages can be selected as the deviation: 0.1%, 0.2%, 0.5%, 1%, 1.5%, 2%, 3%, 5% or 10%.

– The target value, lower tolerance

limit (minimum) and upper tolerance limit (maximum) can be taken over as weighed values from the weighing instrument.

– Target and tolerance limits checked

during input; values must conform to: Upper limit > Target > Lower limit > 1 digit

– Checkweighing range: either 30%

to 170% of the target, or from 10% to infinity

– Application started automatically

with most recent application data

when Combics switched on – Automatic taring – Automatic printing – Toggle the display between weight

and tolerances limits by pressing w.

When tolerances are displayed, weights

exceeding the tolerance limits are

shown with “LL" (too low) or “HH"

(too high). – Digital input/output interface – Info mode for display of tolerance limits

by pressing w (> 2 sec)

Checkweighing entails comparing the current weight value to a defined target. The target value has a tolerance range which can be entered either as an absolute value or percentage (menu item 4.5).

– Entering the tolerance range as

an absolute value (weighed value) (menu item 4.5.1): Start initialization by pressing O; the middle segments of the bar graph flash to prompt the placement of the weight on the weighing instrument. Place the weight on the instrument and press O to store. The bar graph segment for the lower limit flashes to prompt the weight for lower limit. Place the weight on the weighing instrument and press O to store. The bar graph segment for the upper limit flashes to prompt the weight for upper limit. Place the weight on the weighing instrument and press O to store.

– Entering the tolerance range as

a percentage (menu item 4.5.2): A value for the percentage is shown in the numeric display (lower right-hand corner) together with the “%" sign. Press r to change the percentage value (0.1%, 0.2%, 0.5%, 1%, 1.5%, 2%, 3%, 5%, 10%). Start initialization by pressing O; the middle segments of the bar graph flash to prompt the placement of the weight on the weighing instrument. Place the weight on the instrument and press O to store. To can change the percentage value for the tolerance limits again before the target value is stored, press r.

Before the new initialization, the previous initialization values must be deleted by pressing c.
