4 Basic Information (General)
4.1 Proper use
The balance you purchased is intended to determine the weighing value of 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 pan. As soon as a stable weighing value is reached, the weighing value can be read.
4.2 Improper Use · 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.
4.3 Warranty
Warranty claims shall be voided in case:
· Our conditions in the operation manual are ignored · The appliance is used beyond 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
11
TCKE-A/-B-BA-e-2434
4.4 Monitoring of Test Resources In the framework of quality assurance the measuring-related properties of the balance and, if applicable, the testing weight, must be checked regularly. The responsible user must define a suitable interval as well as type and scope of this test. 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. In KERN’s accredited calibration laboratory test weights and balances may be calibrated (return to the national standard) fast and at moderate cost.
5 Basic Safety Precautions
5.1 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.
5.2 Personnel training The appliance may only be operated and maintained by trained staff.
6 Transport and storage
6.1 Testing upon acceptance When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.
6.2 Packaging / return transport 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.

7 Unpacking, Installation and Commissioning
7.1 Installation Site, Location of Use The balances are designed in a way that reliable weighing results are achieved in common conditions of use. You will work accurately and fast, if you select the right location for your balance.
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.
13
TCKE-A/-B-BA-e-2434
7.2 Unpacking and checking Remove device and accessories from packaging, remove packaging material and install the device at the planned workplace. Check if that there has been no damage and that all items of delivery scope are present.
Scope of delivery / serial accessories: · Balance, see chap. 3.1 · Mains adapter · Operating instructions · Protective hood · Flush-mounted hook · Allen key (models with small housing only)
7.3 Assembling, Installation and Levelling Remove transportation lock on the lower side of the balance (models with small housing only)
Install weighing plate and wind shield if necessary. Ensure that the balance is installed in a level position. Level balance with foot screws until the air bubble of the water balance is in the
prescribed circle.
Check levelling regularly
TCKE-A/-B-BA-e-2434
14
7.4 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.
7.5 Rechargeable battery operation (optional)
ATTENTION
The rechargeable battery and the battery match with each other. Only use the delivered mains adapter.
Do not use the balance during the loading process. The rechargeable battery can only be replaced by the same or
by a type recommended by the manufacturer. The rechargeable battery is not protected against all environmental
influences. If the rechargeable battery is exposed to certain environmental influences, it may set on fire or explode. Persons may be injured or material damage may occur. Protect the rechargeable battery against fire and heat. Do not bring the rechargeable battery in contact with fluids, chemical substances or salt. Do not expose the rechargeable battery to high pressure or microwaves. Under no circumstances the rechargeable batteries and the charging unit may be modified or manipulated. Do not use a defective, damaged or deformed rechargeable battery. Do not connect or short-circuit the electrical contacts of the rechargeable battery with metallic objects. Liquid may squirt out from a damaged rechargeable battery. If the liquid gets into contact with the skin or the eyes, the skin and the eyes may be irritated. Ensure the correct polarity when inserting or changing the rechargeable battery (see instructions in the rechargeable battery compartment) The rechargeable battery operation is overridden when the mains adapter is connected. For weighing in mains operation > 48 hrs. the rechargeable batteries must be removed! (Danger of overheating). If the rechargeable battery starts to smell, being hot, changing
15
TCKE-A/-B-BA-e-2434
the colour or being deformed, it must be immediately unplugged from mains supply and from the balance if possible.
7.5.1 Load recharge battery The rechargeable battery pack (Option) is charged using the mains cable supplied.
Before the first use, the rechargeable battery package should be charged by connecting it to the mains power cable for at least 15 hours.
To save the rechargeable battery, in menu (see chap. 10.3.1.) the automatic switchoff function <Autoff> can be activated.
If the capacity of the rechargeable batteries is exhausted, <Lo Bat> appears in the display. Connect the power cable as soon as possible to load the rechargeable battery. Charging time until complete recharging is approx. 8 h.
TCKE-A/-B-BA-e-2434
16
7.6 Connection of peripheral devices
Before connecting or disconnecting of additional devices (printer, PC) to the data interface, always disconnect the balance from the power supply.
With your balance, only use accessories and peripheral devices by KERN, as they are ideally tuned to your balance.
7.7 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have reached the operating temperature (see warming up time chap. 1). During this warming up time the balance must be connected to the power supply (mains, rechargeable accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
7.8 Adjustment
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.
Procedure:
· Carry out adjustment as near as possible to the balance’s maximum weight (recommended adjustment weight see chap. 1). Weights of different nominal values or tolerance classes may be used for adjustment but are not optimal for technical measuring. The accuracy of the adjustment weight must correspond approximately to or, if possible, be better than, the readability [d] of the balance. Info about test weights can be found on the Internet at: http://www.kernsohn.com
· Observe stable environmental conditions. A warm up time (see chapter 1) is required for stabilization.
· Ensure that there are no objects on the weighing plate.
· Avoid vibration and air flow.
· Always carry out adjustment with the standard weighing plate in place.

9.2 Piece counting Before the balance can count parts, it must know the average piece weight (i.e. reference). Proceed by putting on a certain number of the parts to be counted. The balance determines the total weight and divides it by the number of parts, the socalled reference quantity. Counting is then carried out on the basis of the calculated average piece weight.
· The higher the reference quantity the higher the counting exactness. · Especially high reference must be selected for small parts or parts with
considerably different sizes.
· Smallest counting weight see table ,,Technical data”.
9.2.1 Counting with reference quantity 5, 10 or 20 The self-explanatory control panel visualises the sequence of the required steps:
Put the empty container on the weighing plate and press the TARE button. The container is tared, the zero display will appear.
Fill with the container reference parts (e.g. 5, 10 or 20 pieces).
Confirm the reference quantity selected by pressing the key (5x, 10x, 20x). The balance will calculate the average item weight and then displays the quantity of parts. Remove reference weight. The balance is now in piece counting mode counting all units on the weighing plate.
Fill the counting quantity. The piece quantity is shown directly in the display.

11 Communication with peripheral devices via KUP connection Via the interfaces weighing data may be exchanged with connected peripheral devices. Issue may be made to a printer, PC or check displays. In reverse order, control orders and data inputs may be made via the connected devices. The balances are equipped with a KUP connection (KERN Universal Port) as per standard.
KUP connection For all available KUP interface adapters, please visit our webshop at:
http://www.kern-sohn.com

11.1 KERN Communications Protocol (KERN Interface Protocol)
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:
