3 Fundamental information (general)

It is essential to read through and observe the complete operating instructions before installing and commissioning.

3.1 Intended use

The balance you have acquired serves to determine the weighing value of the material to be weighed. It is intended to be used as a “non-automatic“ balance, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing plate. The weighing value can be read off after a stable weighing value has been obtained.

3.2 Inappropriate use

Do not use the balance for dynamic weighing. In the event that small quantities are removed or added to the material to be weighed, incorrect weighing results can be displayed due to the “stability compensation“ in the balance. (Example: Slowly draining fluids from a container on the balance.) Do not leave a permanent load on the weighing plate. This can damage the measuring equipment. Be sure to avoid impact shock and overloading the balance in excess of the prescribed maximum load rating (max.), minus any possible tare weight that is already present. This could cause damage to the balance. Never operate the balance in hazardous locations. The series design is not explosion-proof. Structural alterations may not be made to the balance. This can lead to incorrect weighing results, faults concerning safety regulations as well as to destruction of the balance.

572/573/KB/DS/FKB/FCB/PCB-BA-e-0853

The balance may only be used in compliance with the described guidelines. Varying areas of application/planned use must be approved by KERN in writing.

3.3 Guarantee

The guarantee is not valid following

- non-observation of our guidelines in the operating instructions

- use outside the described applications

- alteration to or opening of the device

- mechanical damage and damage caused by media, liquids

- natural wear and tear

- inappropriate erection or electric installation

- overloading of the measuring equipment

3.4 Monitoring the test substances

The metrology features of the balance and any possible available adjusting weight must be checked at regular intervals within the scope of quality assurance. For this purpose, the answerable user must define a suitable interval as well as the nature and scope of this check. Information is available on KERN’s home page (www.kern-sohn.com

) with regard to the monitoring of balance test substances and the test weights required for this. Test weights and balances can be adjusted quickly and at a reasonable price in KERN’s accredited DKD calibration laboratory (return to national normal).

572/573/KB/DS/FKB/FCB/PCB-BA-e-0853

4 Fundamental safety information

4.1 Observe the information in the operating instructions

Please read the operating instructions carefully before erecting and commissioning, even if you already have experience with KERN balances.

4.2 Staff training

The device may only be operated and looked after by trained members of staff.

5 Transport and storage

5.1 Acceptance check

Please check the packaging immediately upon delivery and the device during unpacking for any visible signs of external damage. In the case of visible damages please obtain a signature from the bearer to serve as confirmation of damage. Do not make alterations to the goods and packaging, do not remove any consignment parts. Report the damage to the parcel service immediately in writing ( within 24 hours).

5.2 Packaging

Please retain all parts of the original packaging in case it should be necessary to return items at any time. Only the original packaging should be used for return consignments. Before despatch, disconnect all attached cables and loose/movable parts, remove weighing plate. Apply any intended transport security devices. Secure all parts, e.g. glass windshield, weighing plate, power unit etc., to prevent slipping and damage.

6 Unpacking, installation and commissioning

6.1 Place of installation, place of use

The balance is constructed in such a way that reliable weighing results can be achieved under normal application conditions. By selecting the correct location for your balance, you will be able to work quickly and precisely.

Therefore please observe the following at the place of installation:

- Place the balance on a firm, level surface;

- Avoid extreme heat as well as temperature fluctuation caused by installing next to a radiator or in the

direct sunlight;

- Protect the balance against direct draughts due to open windows and doors;

- Avoid jarring during weighing;

- Protect the balance against high humidity, vapours and dust;

- Do not expose the device to extreme dampness for longer periods of time. Inadmissible bedewing

(condensation of air moisture on the device) can occur if a cold device is taken into a significantly warmer environment. In this case, please acclimatise the device for approx. 2 hours at room temperature after it has been disconnected from the mains.

- Avoid static charging of the material to be weighed, weighing container and windshield.

Major display deviations (incorrect weighing results) are possible if electromagnetic fields occur as well as due to static charging and instable power supply. It is then necessary to change the location.

572/573/KB/DS/FKB/FCB/PCB-BA-e-0853

6.2 Unpacking

Carefully remove the balance from its packaging, remove the plastic wrapping and position the balance in its intended working location.

6.2.1 Installation

Install the balance in such a fashion that the weighing plate is absolutely horizontally.

6.3 Mains supply

Electric power supply is by means of the external mains supply circuit. The printed voltage level must comply with the local voltage. Only use original KERN mains supply circuits. The use of other makes is subject to approval by Kern.

6.4 Connecting peripheral equipment

The balance must be disconnected from the mains before connecting or disconnecting additional equipment (printer, PC) to or from the data interface.

Only use KERN accessories and peripheral equipment with your balance. These have been ideally coordinated to your balance.

6.5 Initial start-up

A warm-up time of 2 hours stabilises the measured values after switching on.

The accuracy of the balance depends on the local acceleration of the fall. Please be sure to observe the information in the chapter on adjusting.

6.6 Adjustment

As the acceleration value due to gravity is not the same at every location on earth, each balance must be coordinated – in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location ( only if the balance has not already been adjusted to the location in the factory). This adjustment process must be carried out during the initial start-up, after change in location and variation of surrounding temperature. It is also recommendable to adjust the balance periodically during weighing operation in order to obtain exact measured values.

6.7 Adjusting (go to 7.2.6)

Using a precision weight, the accuracy of the balance can be checked at any time and adjusted.

Warning:

With verified balances, this precision adjustment is not possible

Adjustment procedure:

Check that the surrounding conditions are stable. A short warm-up time of about 15 minutes is recommended for stabilisation.

572/573/KB/DS/FKB/FCB/PCB-BA-e-0853

6.7.1 Adjusting for verification (KERN 573)

General Information:

Prior to the procedure of verification the balance has to be adjusted.

Remark: The adjusting is only possible when not being blocked by the adjusting switch.

The switch for this step is located at the bottom of the housing between the two turning feet.

Switch to the right

Adjusting function is released.

This setting has to be selected before starting the adjusting.

Executing the adjusting according to chapter 7.2 “Operation“.

After the adjusting has been completed successfully it is nec-

essary to turn the adjusting switch to the left for blocking.

Switch to the left

Adjusting function is blocked.

After the adjusting has been completed successfully the adjusting has to be blocked by switching to the left.

The balance is now prepared for the procedure of verification.

After the verification the adjusting switch has to be secured by a verification mark against access.

6.8 Verification

General: According to the EU guideline 90/384/EEC balances must be verified officially if they are to be used as follows (legally regulated area):

a) For commercial transactions if the price of goods is determined by weighing b) For the production of medines in pharmacies as well as for analyses in the medical and pharmaceu-

tical laboratory c) For official purposes d) For the production of finished packages

In case of doubt, please contact your local office of weights and measures.

Verification information

An EU qualification approval is available for those balances marked as appropriate for verification in the technical data. In the event that the balance is applied in an area subject to verification as described above, it must be officially verified and re-verified at regular intervals. Re-verification of a balance is carried out in compliance with the respective legal provisions of the states. The term of verification validity for balances in Germany, for example, is normally 2 years. The legal provisions of the country of use are to be observed.

7.4 RS 232 C Data output via interface RS 232 C

RS 232 C Data output via interface RS 232 C General information

As a condition for the data transfer between the balance and a peripheral device (for instance printer, PC ...) both devise have to be set on the same interface parameter (for instance baud rate, parity ...).

7.4.1 There are 4 methods for the data output via RS 232 C

Data output via PRINT-Key

The printing process can be released by the PRINT-key. In this case the settings AUTOPRINT and AUTPRINT PC should be deselected.

AUTOPRINT (Data output, after having loaded the balance)

The setting AUTOPRINT is in the PRINTER-routine, and there it can be selected or deselected. When AUTOPRINT is active the actual weighing value will be sent via the RS 232 interface when the balance has been unloaded and then loaded after having achieved the stability.

AUTOPRINT PC (Continuous data output)

The setting AUTPRINT PC is in the PRINTER-routine, and there it can be selected or deselected. When AUTOPRINT PC is active the actual weighing values will be sent continuously via the RS 232 interface.

Data output by transfer of remote controls

The following functions can be released by the remote controls that will be transferred as ASCII signs to the balance.

t Tare. w a weighing value (or unstable) is sent via RS 232 interface. s a stable weighing value is sent via RS 232 interface. If the balance receives the command w or s, it acts without printing delay.

7.4.2 Description of the data transfer

Structure of each data transfer:

Without Numerator:

Bit-Nr. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 B B B B B B B B 0

0 B g B B CR LF

B*: = Blank or % in the range of zero point. B, 0,

, g: = Blank or weighing value with unit, depending on the load on the weighing plate. CR: = Carriage Return LF: = Line Feed

With Enumerator:

Bit.Nr. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

N N N B* B B B B B B B 0

0 B G B B CR LF

N: = Enumerator

7.4.3 Numerator

The Numerator is found under the menu point “Printer” and can be activated and deactivated. When editing data with the use of the print option, the range of the numerator will increase by one place.

572/573/KB/DS/FKB/FCB/PCB-BA-e-0853

7.5 Printer

With the serial data output RS 232 a printer can be connected. The printout shows the weight in grams. When the counting mode is selected the number of pieces or the weight is printed. When the percent mode is selected, the percentage or the weight will be printed. Press The PRINT-key to print weighing results. Select the enumerator to number the weighing continuously. Turn off the balance or use the CLEAR function to Reset the enumerator to (000).

7.6 Underfloor weighing

Objects which, because of their size or shape, cannot be put on the scale, can be weighed by means of underfloor weighing.

Proceed as follows:

• Switch off the balance.

• Turn the balance over,

without loading the balance plate.

• Open the cover plate on the base of the balance.

• Hang on the hook for underfloor weighing .

• Place the balance over an opening.

• Hang the item to be weighed on the hook and carry out weighing.

! CAUTION !

Take care that the hooks used for the underfloor weighing are stable enough to hold the goods which you wish to weigh (risk of breakage). Always make sure that there are no living beings or materials below the load that could be injured or damaged.

! NOTE !

After completing the underfloor weighing, the opening in the floor of the balance must be closed again (dust protection).

8 Maintenance, upkeep, disposal

8.1 Cleaning

Please disconnect the device from the operating voltage before cleaning.

Only use a cloth dampened with mild suds and not aggressive cleaning agents (solvents or similar). Please ensure that fluids are not able to get into the device and rub off using a clean, soft cloth. Loose sample residue/powder can be removed carefully using a brush or hand vacuum cleaner.

Remove any spilt material to be weighed immediately.

8.2 Maintenance, upkeep

The device may only be opened by trained service engineers authorised by KERN. Disconnect from the mains supply before opening.

8.3 Disposal

The operating company shall dispose of the packaging and the device in compliance with the valid national or regional law of the operating location.

9 Troubleshooting

The balance should be switched off for a short time following an interruption in the programme sequence and disconnected from the mains supply. It is then necessary to repeat the weighing process from the beginning.

Help:

Interruption Possible cause

Weight display is not illuminated.

• The balance is not switched on.

• The mains supply connection has been interrupted

(mains cable not plugged in/faulty).

• Power supply interrupted. .

The weight display changes continually

• Draught/air movement

• Table/floor vibrations

• The weighing plate is in contact with foreign matter.

• Electromagnetic fields / static charging (choose differ-

ent location/switch off interfering device if possible)

The weighing result is obviously incorrect

• The balance display is not set to zero

• Adjustment is no longer correct.

• Great fluctuations in temperature.

• Electromagnetic fields / static charging (choose differ-

ent location/switch off interfering device if possible)

Switch the balance off if other error messages should appear and then switch on again. Contact the manufacturer if the error message does not disappear.
