2. General Safety Instructions

2.1 Duties of the owner-operator

Follow national accident prevention regulations and all operator health and safety at work and operating regulations.

• Observe all safety regulations of the crane manufacturer.

• The balance may only be used for the proposed purpose. Any type of use which is not specified in these operating instructions, will be considered as improper use. The customer is solely responsible for material damage and injury of persons resulting from an improper use, Messrs. KERN & Sohn will not be liable under any circumstance. Messrs. KERN & Sohn cannot be held liable, if the suspended balance is modified or used improperly and if damage is resulting from such use.

• Inspect and service suspended balance, crane and load suspension devices regularly (see chap. 8.3).

• Log the test result and keep it in the logbook.

2.2 Organizational measures

• Only trained and instructed staff may operate the balance.

• Make sure that the operating instructions are kept nearby the operation site of the suspended balance.

• Assembly, commissioning and maintenance should only be carried out by trained specialists.

• Weight-bearing components must not be replaced

2.3 Environmental conditions

• Never operate suspended balance in spaces exposed to explosion hazards. The serial version is not explosion protected.

• Operate the suspended balance only under environmental conditions as specified in these operating instructions (especially in chapter 1 „Technical data“).

• Do not expose the suspended balance to strong humidity. 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.

• Do not use suspended balance in environments exposed to corrosion hazards.

• Protect the suspended balance against high humidity, vapours and dust.

• Major display deviations (incorrect weighing results) may be experienced should electromagnetic fields (e.g. due to mobile phones or radio equipment), static electricity accumulations or instable power supply occur. Change location or remove source of interference.HCB_HCN-BA-e-1644 16

2.4 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.

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 suspended on the load receptor only vertically, manually, carefully and without jerks. As soon as a stable weighing value is reached the weighing value can be read.

• Use the suspended balance only for lifting and weighing of freely movable loads.

• Danger of injury due to improper use. Not allowed are e.g.: - Exceeding the allowed nominal load of crane, suspended balance or any type of load attachment devices - Conveying persons, - Pulling loads over an inclined surface, - Tearing-off, pulling or towing loads.

• Modifications or reconstructions of the suspended balance or of the crane are not allowed.

Do not use 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“. (Example: Slowly draining fluids from a container suspended on the balance.) Do not leave permanent load suspended on the balance. This may damage the measuring system as well as safety-relevant parts. Make sure that never persons or objects are under the load which could be injuried or damaged! The balance is not suitable for weighing persons! The balance does not correspond to the law of medical products (MPG).

The balance may only be used according to the described conditions. Other areas of use must be released by KERN in writing.17 HCB_HCN-BA-e-1644

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 and damage caused by media, liquids,

• Natural wear and tear

• The appliance is improperly set up or incorrectly electrically connected

• The measuring system is overloaded

2.8 Safety-conscious working

• Do not stand under swinging loads, see chap. 5.1.

• Position the crane in a way that the load is lifted vertically.

• When working with the crane and suspended balance wear personal safety equipment (helmet, safety shoes etc.).

2.9 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 DKD calibration laboratory test weights and balances may be calibrated (return to the national standard) fast and at moderate cost.

2.10 Testing upon acceptance

Inspect packaging immediately upon receipt and inspect device when unpacking, see chap. 4.1. in the event of any evident damage.

2.11 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, accumulator or battery). The accuracy of the balance depends on the local acceleration of gravity. Strictly observe hints in chapter Adjustment. For checking original dimensions, s. chap. 4.3

2.12 Shutdown and storage

• Remove suspended balance from crane and remove all attachment devices from the suspended balance.

• Do not store suspended balance outdoors.HCB_HCN-BA-e-1644 18

4.4 Battery operation

3 x 1.5V AA batteries 2 x 1.5V AA batteries If the batteries are empty, in the balance display appears “LO”. Press ON/OFF-key and replace the batteries. Open battery compartment, replace batteries and close battery compartment again. In order to save the battery, the balance switches automatically off after 4 minutes without weighing This auto-off function can be deactivated in the menu, see chap. 6. When the suspended balance is out of operation for a longer period, remove the batteries.25 HCB_HCN-BA-e-1644

4.5 Suspending the balance

Condition The crane needs a safety bracket (1) that the unloaded suspended balance cannot fall down. If the safety bracket is missing or damaged, please contact the crane manufacturer in order to receive a hook with this safety equipment. Attach the suspended balance on the lower hook of a crane and close the safety bracket. The crane scale’s upper eyelet should rest in the saddle (2).HCB_HCN-BA-e-1644 26

Risk of injury due to falling loads!

Take great care when operating the crane and follow the general rules for crane operation.

Check all parts (hook, carbines, rings, rope slings, cables, chains etc.) for excessive wear or damage

If faults can be seen on the safety bracket of the crane hook or if it is missing completely, the scales must not be used. Work only with appropriate speed Always avoid vibrations and horizontal forces. Avoid any kind of shock, torsion and oscillating (e.g. caused by inclined suspending) Do not use the suspended balance for conveying loads. Do not stand or go under suspended loads.

Do not use on building site. Keep an eye on suspended loads. (example) Do not exceed nominal rated load of crane, suspended balance or any kind of attachment device on the suspended balance.27 HCB_HCN-BA-e-1644

5.2 Loading the suspended balance

For good weighing results observe the following, illustrations see next page: Only use load attachment devices which guarantee a one-spot suspension and where the scales can be suspended freely. Do not use too large load attachment devices which do not guarantee any one- spot suspension. Do not use multiple suspensions. Do not pull or push the load or the loaded balance. Do not pull the hook horizontally. Loading the balance

1. Position the hook of the suspended balance over the load.

2. Move downwards the suspended balance until the load can be suspended on the

hook of the balance. Reduce the speed when the respective height is going to be reached.

3. Suspend load on the attachment device. Ensure that all safety-relevant devices

are functional (e.g. the safety latch is closed). If the load is fixed by slings, ensure that the slings rest completely on the saddle of the balance hook.

4. Lift-off the load slowly.

When the load is fixed by slings, ensure that the load is well balanced on both sides and that the slings are correctly positionedHCB_HCN-BA-e-1644 28 + Always used the correct load attachment device, e.g. HCB 100K200 Only use attachment devices which guarantee a one-point suspension and where the scales can be suspended freely.

Do not use too large attachment devices which cannot guarantee a one-point suspension.29 HCB_HCN-BA-e-1644

Start-up Press the ON/OFF key. The display lights up and the balance carries out a selftest. The selftest is completed when the weight value 0 appears on the display. Switching Off Press the ON/OFF key for a long time.

Suspend preload. Press the TARE button, the zero display disappears. The weight of the container is now internally saved.

Weigh the material, the net weight will be indicated. After removing the preload weight appears as negative display. To delete the tare value, remove load from the suspended balance and press the TARE button.

Load the suspended balance. The weight value will be displayed at once.

Overload warning Overloading exceeding the stated maximum load (max) of the balance, minus a possibly existing tare load, must be strictly avoided. This could cause damage to the balance. Exceeding the maximum load is indicated by the display „E“. Unload balance or reduce preload.31 HCB_HCN-BA-e-1644

Confirm setting with the HOLD button. Suspend the material to be weighed The weight value is fixed and displayed depending on the setting (H1 – H4) (see chap. 5.7), represented by the [] in the upper left.

5.7.2 Animal weighing function

This function is suitable for busy weighing procedures. The result is a mean value formed by 16 weighing values which is found out within 3 seconds. Switch on the balance, keep the HOLD-key pressed until the current setting „Hx“ (H1 – H6) appears. Press ON/OFF button repeatedly until the setting „H5“ is displayed. Confirm setting with the HOLD button. Suspend the material to be weighed Press the HOLD-key, the display counts reverse from 3 -1. The calculated mean value is indicated, symbolised by the [] top left. Before further measurements press first the ON/OFF/TARE-key.33 HCB_HCN-BA-e-1644

5.7.3 Peak value function

This function displays the highest load value (peak value) of a weighing. Measuring frequency: 200ms Attention: Never exceed the maximum permitted load of the peak value on the balance (!!Danger of breaking!!). Switch on the balance, keep the HOLD-key pressed until the current setting „Hx“ (H1 – H6) appears. Press ON/OFF button repeatedly until the setting „H6“ is displayed. Use the HOLD-key to confirm your selection Suspend the material to be weighed The peak value appears for a short time, symbolised by the [] top left. The balance returns automatically to zero and is ready for further measurement.

When the balance is switched off, press the HOLD-key and keep it pressed Do not release the HOLD-key. Press also the ON/OFF/TARE-key and keep it pressed Keep the ON/OFF/TARE-key pressed, however release the HOLD-key Press HOLD-key anew Keep both keys pressed until in the display “tr” appears Release both keys. The balance is situated in the menu. Using the ON/OFF/TARE button you can select between the following functions:

• tr (Zero tracking) : ON/OFF

• AF (Auto off): ON/OFF

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 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 balance periodically in weighing operation. Observe stable environmental conditions. A warming up time of approx. 1 minute is recommended for stabilization. Prepare adjustment weight, for details see chap. 1 „Technical data“. Switch-off balance and attach a carrying help if necessary. Switching on balance with attached support aid. Press Unit button and hold down (approx. 3 secs) until „CAL“ is displayed. Wait until the weight value of the required adjustment weight (e.g. 10 kg, see chap. 1) is displayed. Attach adjustment weight, a short time later „F“ will appear.

After adjustment the balance automatically returns to weighing mode. An adjusting error or incorrect adjusting weight will be indicated by the error message; repeat adjustment procedure35 HCB_HCN-BA-e-1644

8. Cleaning, Maintenance and Disposal

Danger Risk of injury and risk of material damage! The suspended balance is part of the lifting gear! For a safe operation please observe the following: Have carried out a regular maintenance by trained specialized staff Carry out regular maintenance and servicing, see chap. 8.3. Have the parts exchanged only by trained specialized staff. If there arose discrepancies with the safety checklist, the balance must not more be put into operation. Do not repair the suspended balance yourself. Repair may only be carried out by service partners authorized by Messrs. KERN.

8.1 Cleaning and Disposal

Damage to suspended balance! Do not use industrial solutions or chemicals (e.g. acid embrittlement). Clean the keyboard and the display with a soft cloth soaked in mild window cleaning agent. 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.HCB_HCN-BA-e-1644 36

8.2 Regular maintenance and care

The regular 3-month maintenance may only be carried out by an expert with competent knowledge of working with suspended balances. Thereby the national regulations for prevention of accidents as well as the working, operation and safety regulations of the owner-operator. To check the dimensions only use suitable test devices. The regular 12-month maintenance must only be carried out by trained specialized staff (KERN customer service). The results of the maintenance must be written down in the checklist (chap. 8.3). The additional results of the extended maintenance have to be entered in the checklist (chapter 9.1). The load suspension device is to be cleaned before inspection, see chap. 8.1. Replaced parts (attachment device) must also be recorded (chap. 9.2)37 HCB_HCN-BA-e-1644 Regular maintenance: Prior to each usage

• Check for fault-free operation of the attachment devices Initial start-up, every 3 months or definitely after 12 500 weighing processes

• Check all dimensions, see checklist chap. 8.3

• Check the attachment device for wear and tear, such as e.g. plastic deformation, mechanical damage (unevenness), notches, striation, cracks, corrosion, thread damage and torsions.

• Check safety fastening on the attachment device for faults and fault-free operation.

• Remove balance from use immediately if a reading exceeds the permitted deviation from the original reading (see checklist, chap. 8.3) or any other fault is identified.

• All repairs and replacement parts (e.g. hook) must be documented by the service partner (see list, chap. 9.2). Every 12 months or in any case after 50 000 weighings

• If the enhanced maintenance has to be carried out by trained staff (KERN customer service). At this general revision all load carrying parts must be checked for gaps with magnetic powder Every 10 years or anyway after 500,000 weighings

• Replace the crane scales entirely Note During the revision watch out for wear and tear according to the following drawings (chap. 8.3). Rejection criteria: Load suspension devices may no longer be used when e.g. + Deviations are identified during the inspections specified for servicing. + The type or load rating plate is missing. + Load suspension devices known to have been overloaded or subject to other harmful influences may no longer be used and/or may be re-used only after inspection.HCB_HCN -BA-e-1644 38
