The scale can be used anywhere in Germany if the geographical data is as follows:

– Latitude: 51.00 degrees

Elevation: 513 meters This data corresponds to the following value: Acceleration of gravity: 9.810 m/s

–2

These values are calculated for Germany based on a mean value for the Earth’s acceleration. The greater the precision of the geographical data entered, the greater the precision achieved with the weighing instrument; the tolerance range, however, is also restricted accordingly.

The tolerance ranges, for example for a scale with 3000 e, are as follows:

– ±100 km for the latitude and – ±200 m for the elevation above sea level.

!If used outside the specified zone, the

scale must be re-verified for use in legal metrology. Please contact an authorized service technician.

Seal on Indicators Verified for Use in Legal Metrology in the EU*:

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 the seal is broken, the validity of the version becomes null and void, and you must have your scale re-verified.

Unpacking the Platform

Important note: These instructions apply to platforms that are 60 x 80 cm and larger.

§ Remove the weighing platform and weighing pan from the packaging.

§ When transporting or lifting the device, hold the unit on the longer sides and observe the

safety precautions (wear safety shoes and gloves if necessary).

§ Remove any plastic wrapping, packaging strips and styrofoam.

Removing the Transport Locking Device

§ Bring the scale to the location where it will be used and remove the weighing pan.

§ Loosen the transport locking device by removing screw 1.

§ Loosen screw 2, turn the fastening bracket by 180? and then tighten screw 2.

§ Tighten screw 1 again at the lever.

Important Note Regarding Transport of the Weighing Platform

!Be sure to refasten the transport locking device before transporting the weighing

platform.

Level the weighing platform at the weighing location using the adjustable feet so that the air bubble is centered in the level indicator circle. Check that all four adjustable feet are in contact with the surface. The load must be equally distributed over all four leveling feet.

Connecting the Equipment to AC Power

§ Check the voltage rating and the plug design.

$ The scale is powered through the pre-installed power cord. The power supply is built

into the scale, which can be operated with a supply voltage of 100V to 240V. 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 AC adapter does not match the rating or standard you use, please contact your Sartorius office or dealer. The power connection must be made in accordance with the regulations applicable in your country.

§ To power a protective class 1 device, plug the power cord into an electrical outlet

(mains supply) that is properly installed with a protective grounding conductor (protective earth = PE).

Safety Precautions

If your local AC output does not have a protective grounding conductor (protective earth), have a certified electrician install equivalent protection according to your country’s valid installation requirements. Make sure the protective grounding effect is not neutralized by use of an extension cord that lacks a protective grounding conductor.

Connecting Electronic Peripheral Devices

§ Make absolutely sure to unplug the device from AC power before you connect or disconnect

a peripheral device (printer or PC) to or from the interface port.

Warmup Time

To deliver exact results, the device must warm up for at least 30 minutes after initial connection to AC power or after a relatively long power outage. Only after this time will the device have reached the required operating temperature.

Using Equipment Verified as Legal Measuring Instruments in the EU*:

$ Make sure to allow the equipment to warm up for at least 24 hours after initial connection

to AC power or after a relatively long power outage.

Installing the Verification Adapter for Use in Legal Metrology

(on verifiable models only)

§ Remove the nut located on the back of the indicator

§ Use the slotted screw to install the adapter plate

§ Affix the verification seal over the adapter

Leveling the Weighing Platform

Purpose: – To compensate for uneven areas at the place of installation – Make sure that the equipment is placed in a perfectly horizontal position for

consistently reproducible weighing results

Always re-level the weighing platform after changing the place of installation.

§ Remove the weighing pan.

§ Level the weighing platform using the four adjustable feet. Keep turning the feet

until the air bubble is centered in the level indicator circle.

§ Loosen the lock nuts on the leveling feet using an SW17 wrench.

§ Use an SW5 Allen wrench to extend or retract the leveling feet.

> Setting the adjustable feet:

Raise the weighing platform by extending the leveling feet (turning clockwise). Lower the weighing platform by retracting the leveling feet (turning counterclockwise).

§ After aligning the weighing platform, tighten the lock nuts against the platform frame. > Small platforms (1 weighing cell): against the platform frame,

large platforms (4 weighing cells): against the platform foot.

§ Make sure that all the leveling feet are touching the surface.

The load must be equally distributed over all the leveling feet.

§ Once you have leveled the weighing platform, tighten the lock nuts.

§ Place the weighing pan back onto the weighing platform.

Operating Tolerances

Never exceed the maximum capacity of the weighing platforms. The maximum loading capacities of the weighing platforms are listed in the table below and depend on the position of the weight loaded on the platform (center, sides, one-sided corner load):

Platform dimensions Center Side Corner 320 x 240 50 35 20 400 x 300 130 85 45 500 x 400 300 200 100 500 x 400 (P*) 600 400 200 650 x 500 (S**) 450 300 150 800 x 600 (P*) 1,200 800 400 800 x 600 (S**) 900 600 300 800 x 800 4,500 3,000 1,500 1000 x 800 4,500 3,000 1,500 1000 x 1000 4,500 3,000 1,500 1250 x 1000 4,500 3,000 1,500 1500 x 1250 4,500 3,000 1,500 1500 x 1500 4,500 3,000 1,500 2000 x 1500 4,500 3,000 1,500

Shock Resistance

The weighing platform features a rugged construction, but you should not allow objects

to fall onto the weighing pan. Also avoid bumps to the side of the unit and shocks.

The weighing platform withstands the loads specified in standard DIN 1EC68, Part 2-27.

Important Note About Planning Structures for Attachment to the Weighing Platform

The weighing platform is suitable for installation in systems. The scale drawings should

be used as the basis for selecting any necessary structures to be affixed to the platform.

Use the YAS041S fastening set to secure the weighing platform.

Moving or rotating parts on the weighing pan must be designed so that they do not

influence the weighing results. For example, rotating parts must be balanced. The

weighing pan must have clearance on all sides to prevent any falling objects or dirt from

creating a connection between the weighing platform and any permanent structures.

Cables and hoses between the weighing platform and other devices must not exert any

force on the weighing platform. These cables must not touch the weighing pan.

When setting up systems in hazardous areas (zone 2 or 22), be sure to observe and

comply with the relevant regulations (e.g., EN60079-14).

Pay special attention that electrostatic charges resulting from moving parts

(e.g., conveyors) are avoided or discharged.

Preload Range (Zero-Point Range)

The weight of any structures that are permanently mounted on the weighing platform

constitutes the “preload.” The preload is electronically compensated in the weighing

platform so that the entire weighing range is available and so that the scale can be

zeroed or calibrated (using external weights).

Larger preloads will lead to a reduction of the weighing range. The weight on the scale

may not fall below the following weighing range values:

– At least 30 kg of the weighing range must remain for models CH*G-150 1G-H – At least 60 kg of the weighing range must remain for models CH*G-300 1G-H

!You must always set the preload prior to verifying the scale for legal metrology.

All structures must be mounted on the weighing platform before it is connected to AC

power.

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.

Operation

Example

External calibration and manual adjustment with default weights

Setup menu settings:

1.9.1; 1.10.2

( Unload and zero the weighing instrument )> 2 sec Start calibration (e.g., when calibration prompt is flashing: W)

The following is displayed for 2 seconds

You are prompted to place the required weight on the weighing instrument (e.g., 10 kg)

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)

CW Scales

– 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 “Care and Maintenance"). The equipment must be re-verified after the seal has been broken.

CH Scales

– Using a verified scale as a legal measur-

ing instrument: Before using the scale as a legal measuring instrument, you must carry out an internal calibration operation by selecting the “Internal Calibration” function at the place of installation.

– To do so, press and hold the --- key.

During internal calibration, “CI” (for internal calibration) appears in the display. Once the calibration procedure is complete, a weight will be displayed automatically.

Position the calibration weight on the weighing instrument

The difference between the weight value and the true mass is displayed, with ± sign.

Operating: CW2P | CW2P | CW1NFS | CW2FS

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.

– Tare function:

1) If you store a tare (weight value) by

pressing the ) key, you can later enter a tare value manually. The tare value you enter is added to the stored tare value. Setting: menu code 3.25.1 (factory default)

2) A tare value entered manually overwrites a stored tare value (weight value). If you enter a tare value manually, a tare value (weight value) stored later overwrites the manually entered value. Setting: menu code 3.25.2 Operating menu setting: APPL : Z : 3.25.

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.
