3.1 Utilisation in accordance with specification.

The display unit acquired by you is used in combination with a weighing plate and serves to determine the weighing value of material to be weighed. It is intended to be used as a “non-automatic weighing system”, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing plate. As soon as a stable weighing value is reached the weighing value can be read.

• Our balances are non-automatic balances and not provided for use in dynamic weighing processes. However, the balances can also be used for dynamic weighing processes after verifying their individual operative range, and here especially the accuracy requirements of the application.

• Do not leave permanent load on the weighing plate. This may damage the measuring system.

• Impacts and overloading exceeding the stated maximum load (max) of the balance, minus a possibly existing tare load, must be strictly avoided. Balance may be damage by this.

• Never operate the balance in explosive environment. The serial version is not explosion protected.

• The structure of the balance may not be modified. This may lead to incorrect weighing results, safety-related faults and destruction of the balance.

• The balance may only be used according to the described conditions. Other areas of use must be released by KERN in writing.10 KFS-TM-BA_IA-def-2321 English

Warranty claims shall be voided in case

• Our conditions in the operation manual are ignored

• The appliance is used outside the described uses

• The appliance is modified or opened

• Mechanical damage or damage by media, liquids, natural wear and tear

• The appliance is improperly set up or incorrectly electrically connected

• The measuring system is overloaded

3.4 Monitoring of Test Resources

In the framework of quality assurance the measuring-related properties of the bal-ance and, if applicable, the testing weight, must be checked regularly. The respon-sible user must define a suitable interval as well as type and scope of this test. In-formation 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. In KERN's accredited calibration laboratory test weights and balances may be calibrat-ed (return to the national standard) fast and at moderate cost. 4 Basic Safety Precautions

4.1 Pay attention to the instructions in the Operation Manual

Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances.

4.2 Personnel training

The appliance may only be operated and maintained by trained personnel.KFS-TM-BA_IA-def-2321 11 English 5 Transport and storage

5.1 Testing upon acceptance

When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.

Keep all parts of the original packaging for a possibly required return. Only use original packaging for returning. Prior to dispatch disconnect all cables and remove loose/mobile parts. Reattach possibly supplied transport securing devices. Secure all parts such as the wind screen, the weighing plate, power supply unit etc. against shifting and damage. 6 Unpacking and placing

6.1 Installation Site, Location of Use

The display units are designed in a way that reliable weighing results are achieved in common conditions of use. Precise and fast work is achieved by selecting the right place for your display unit and your weighing plate. On the installation site observe the following:

• 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. Non-permitted condensation (condensation of air humidity on the appliance) may occur if a cold appliance is taken to a considerably warmer environment. In this case, acclimatize the disconnected appliance for ca. 2 hours at room temperature.

• Avoid static charge of goods to be weighed or weighing container.

• Do not operate in areas with hazard of explosive material or in potentially explosive atmospheres due to materials such as gasses, steams, mists or dusts.

• Keep away chemicals (such as liquids or gasses), which could attack and damage the balance inside or from outside.

• In the event of the occurrence of electromagnetic fields, static charges (e.g., when weighing / counting plastic parts) and unstable power supply, large display deviations (incorrect weighing results, as well as damage to the scale) are possible. Change location or remove source of interference.12 KFS-TM-BA_IA-def-2321 English

6.2 Scope of delivery / standard accessories:

Carefully remove the display unit from packaging, remove plastic cover and place it in the designated work area. Mount the display unit in a way that facilitates operation and where it is easy to see. To be used with table leg and wall fixture Wall fixture

Push table leg in guide rail [11] up to end stop [12], see chap. 2.KFS-TM-BA_IA-def-2321 13 English Using with tripod (optional)

(Example of illustration)

6.4 Mains connection

Select a country-specific power plug and insert it in the mains adapter.

Check, whether the voltage acceptance on the scales is set correctly. Do not connect the scales to the power mains unless the information on the scales (sticker) matches the local mains voltage. Only use KERN original mains adapter. Using other makes requires consent by KERN.

Important: ➢ Before starting your weighing balance, check the mains cable for damage. ➢ Ensure that the power unit does not come into contact with liquids. ➢ Ensure access to mains plug at all times.

As the acceleration value due to gravity is not the same at every location on earth, each display unit with connected weighing plate 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 weighing system has not already been adjusted to the location in the factory). This adjustment process must be carried out for the first commissioning, after each change of location as well as in case of fluctuating environment temperature. To receive accurate measuring values it is also recommended to adjust the display unit periodically in weighing operation.

• Provide adjustment weight.

• The required adjustment weight depends on the capacity of the weighing system. Carry out adjustment as near as possible to the scale’s maximum weight. Info about test weights can be found on the Internet at: http://www.kern-sohn.com

• Observe stable environmental conditions. Stabilisation requires a certain warm-up time.KFS-TM-BA_IA-def-2321 15 English Call up menu: Switch-on balance and during the selftest press . Ensure that there are no objects on the weighing pan. Reset to zero if necessary by pressing . Go to weighing mode and press and hold for approx. 5-6 seconds until FUNC followed by F0 iSn appears. Release button. Press repeatedly until F2 dm is displayed.

On verified weighing systems press the adjustment switch! Press and select the set weighing scales type by . = Single-range balance = Dual range balance = Multi-interval balance Acknowledge with .

Press repeatedly until „CAL“ will be displayed.16 KFS-TM-BA_IA-def-2321 English Acknowledge by and select desired setting with . = Linearization = Adjustment

How to carry out adjustment: Confirm menu setting nonLin with .

Ensure that there are no objects on the weighing pan. LoAd will be displayed after standstill control has been carried out. Put the required adjustment weight carefully in the centre of the weighing pan. After successful adjustment, the weighing scales will carry out a selftest. During this selftest remove the adjustment weight and the weighing scales will automatically return to weighing mode. An adjusting error or incorrect adjusting weight will be indicated by the error message; repeat adjustment procedure.KFS-TM-BA_IA-def-2321 17 English

Linearity shows the greatest deviation of a weight display on the scale to the value of the respective test weight according to plus and minus over the entire weighing range. If linearity deviation is discovered during a monitoring of test resources, you can improve this by means of linearization.

• Carrying out linearization is restricted to specialist staff possessing well acquainted with the workings of weighing scales.

• The test weights to be used must be adapted to the weighing scale’s specifications; see chapter “monitoring of test resources”.

• Observe stable environmental conditions. Stabilisation requires a certain warm-up time.

• Do not remove the adjustment weight during linearization in step LOAD 1 to LOAD 4, merely increase it instead. Conversely do not remove the adjustment weight during step LOAD 4 to LOAD 1, merely increase it instead.

• After successful linearisation you will have to carry out calibration; see chapter “testing instruments control”.

Ensure that there are no objects on the weighing plate.

“LoAd 1” will be displayed after standstill control has been carried out. Put the first adjustment weight approx. 1/4 Max (see table 1) carefully in the centre of the weighing pan. “LoAd 2” will be displayed after standstill control has been carried out. Put the second adjustment weight approx. 2/4 max (see table 1) carefully in the centre of the weighing pan. “LoAd 3” will be displayed after standstill control has been carried out. Put the third adjustment weight approx. 3/4 max (see table 1) carefully in the centre of the weighing pan. “LoAd 4” will be displayed after standstill control has been carried out. Put the forth adjustment weight approx. 4/4 max (see table 1) carefully in the centre of the weighing pan. After successful standstill control the balance carries out a selftest, then it automatically returns to weighing mode.

• An adjusting error or incorrect adjusting weight will be indicated by the error message; repeat adjustment procedure.KFS-TM-BA_IA-def-2321 19 English

General: According to EU directive 2014/31/EU balances must be officially verified if they are used as follows (legally controlled area):

• For commercial transactions if the price of goods is determined by weighing.

• For the production of medicines in pharmacies as well as for analyses in the medical and pharmaceutical laboratory.

• For official purposes

• For manufacturing final packages In cases of doubt, please contact your local trade in standard. Balances in the legally controlled area (-> verified balances) must keep the error limits in the verification validity period – normally they are the double of the verification error limits. When this verification validity period expires, a re-verification must be carried out. Should be necessary an adjustment of the balance to keep the verification error limits to satisfy the reverification requirements, this is not deemed a warranty case. Verification notes: An EU Qualification Approval is in existence for verified weighing systems. If a balance is used where obligation to verify exists as described above, it must be verified and re-verified at regular intervals. Reverification is carried out according to the relevant national statutory regulations. The validity for verification of balances in Germany is e.g. 2 years. The legal regulation of the country where the balance is used must be observed!

Verification of the weighing system is invalid without the "seals". The seal marks attached on balances with type approval point out that the balance may only be opened and serviced by trained and authorised special- ist staff. If the seal mark is destroyed, verification looses its validity. Please observe all national laws and legal regulations. In Germany a re-verification will be necessary.20 KFS-TM-BA_IA-def-2321 English Notes on verified weighing systems In verified weighing systems the access to menu items F1, F2, F3 of the configuration menu will be blocked. To cancel the access block, go to menu item F3 APP of the configuration menu (See chap. 12.4) and change the setting to „on”. Position of seals and adjusting switch:

The limit is reached when the total weighing range capacity is full. To delete the tare value, remove load from weighing plate and press .

There is also the possibility to enter a known tare value via the numeric keypad. Enter the tare value and acknowledge by .

During piece counting parts can either be counted into a container or out of a container. To count a greater number of parts the average weight per part has to be determined with a small quantity (reference quantity). The larger the reference quantity, the higher the counting exactness. High reference must be selected for small parts or parts with considerably different sizes.

• The average piece weight can only be determined by stable weighing values.

• If weighing values are under zero, the piece counter display shows a negative number of items.

• The message LIGHT appearing on the display indicates that load falls below minimum weight value.

• Delete incorrect entries by pressing .

• The accuracy of an average item weight can be improved at any time during additional counting processes. For this purpose add additional items and press . After the reference optimization sounds a signal tone. As the additional pieces increase the base for the calculation, the reference also becomes more exact.24 KFS-TM-BA_IA-def-2321 English

This data exchange is asynchronous using ASCII - Code. The following conditions must be met to provide successful communication between the weighing system and the printer.

• Use a suitable cable to connect the display unit to the interface of the printer. Faultless operation requires an adequate KERN interface cable.

• Communication parameters (baud rate, bits and parity) of display unit and printer must match.

KCP is a standardized set of interface orders for KERN balances, which allows many parameters and device functions to be called up and controlled. KERN devices that have KCP can use it to connect easily to computers, industrial control systems and other digital systems. A detailed description you will find in the „KERN Communications Protocol“ manual, available in the download area on our KERN homepage (www.kern-sohn.com). To activate KCP please observe the menu overview of your balance’s operating instructions. KCP is based on simple ASCII orders and replies. Every interaction consists of an order, possibly with arguments separated by spaces and finished by <CR>< LF>. The KCP orders supported by your balance may be queried emitting the order „I0“ followed by CR LF. Extract of the mostly used KCP orders: Command Function

Stable weighing value for the weight is sent via the RS232 interface

Weighing value for the weight (stable or unstable) is sent via the RS232 interface

No data are sent, the balance carries out the tare function.

No data are sent, the zero-display appears.

Before any maintenance, cleaning and repair work disconnect the appliance from the operating voltage.

Please do not use aggressive cleaning agents (solvents or similar agents), but a cloth dampened with mild soap suds. Take care that the device is not penetrated by fluids and polish it with a dry soft cloth. Loose residue sample/powder can be removed carefully with a brush or manual vacuum cleaner. Spilled weighing goods must be removed immediately.

10.2 Servicing, maintenance

The appliance may only be opened by trained service technicians who are authorized by KERN. Before opening, disconnect from power supply.

Disposal of packaging and appliance must be carried out by operator according to valid national or regional law of the location where the appliance is used.62 KFS-TM-BA_IA-def-2321 English 11 Error messages, troubleshooting guide In case of an error in the program process, briefly turn off the appliance and disconnect from power supply. The weighing process must then be restarted from the beginning. Fault Possible cause

The displayed weight does not glow.

• The display unit is not switched on.

• Mains power supply interrupted (mains cable defective).

• Power supply interrupted.

• (Rechargeable) batteries are inserted incorrectly or empty

• No (rechargeable) batteries inserted.

The displayed weight is permanently changing

• Draught/air movement

• Table/floor vibrations

• Weighing pan has contact with other objects.

• Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

The weighing result is obviously incorrect

• The display of the balance is not at zero

• Adjustment is no longer correct.

• The weighing pan is not level

• Great fluctuations in temperature.

• Warm-up time was ignored.

• Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

• Weighing range exceeded u-Err

• Transport safety device has not been removed

Should other error messages occur, switch device off and then on again. If the error message remains inform manufacturer.KFS-TM-BA_IA-def-2321 63 English 12 Installing display unit / weighing bridge

Installation / configuration of the weighing system must be carried out by a well acquainted specialist with the workings of weighing balances.

12.2 Weighing system design

The display unit is suitable for connection to any analogue platform in compliance with the required specifications. The following data must be established before selecting a weighing cell:

• Weighing balance capacity This usually corresponds to the heaviest load to be weighed.

• Preload This corresponds to the total weight of all parts that are to be placed on the weighing cell such as upper part of platform, weighing pan etc.

• Total zero setting range This is composed of the start-up zero setting range (± 2%) and the zero setting range available to the user via the ZERO-key (2%). The total zero setting range equals therefore 4 % of the scale’s capacity. The addition of weighing scales capacity, preload and the total zero setting range give the required capacity for the weighing cell. To avoid overloading of the weighing cell, include an additional safety margin.

• Smallest desired display division64 KFS-TM-BA_IA-def-2321 English

12.3 Connecting a platform

Disconnect the display unit from the power supply. Weld the individual wires of the load cell cable to the printed circuit board. Please see diagram below for plug allocation.KFS-TM-BA_IA-def-2321 65 English
