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.
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. 2.4 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.
2.7 Safe working Do not stand underneath suspended loads! Position the crane in a way that the load is lifted vertically. When working with the crane and crane scales wear personal safety equipment (helmet, safety shoes etc.). 2.8 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.
3. The crane scales at a glance The crane scales are a multi-purpose and cost-saving solution for overhead weighing applications such as e.g. recycling, metal processing, machine engineering, transport and logistics. With the infrared remote control, operation will be more comfortable yet. 3.1 Overview Balance 1 2 3 4 5 Shackle Display Keyboard Safety bracket Hook, not revolvable Infrared remote control unit Keyboard, see chapter 3.
3.2 3.
3.5 Infrared remote control unit The balance can be operated by the radio remote control like by a keyboard. All functions (excepted ON/OFF) can be selected. The red LED must light up when any button is pressed. If it does not light up, the batteries in the remote control must be exchanged. Range on free surface (free of buildings) approx. 10 m. Point the remote control at the balance. „ON“ Switching on only possible during standby mode of the balance.
3.6 Label Do not stand or go under suspended loads. Do not use on building site. Keep an eye on suspended loads. Do not exceed nominal load of crane scales. (example) The product conforms to the requirements of the German Equipment and Product Safety Act.
4. Commissioning Attention: Always observe chapter 2 „General Safety Instructions“! 4.1 Unpacking Once delivered and unpacked, crane scales will not be taken back. SAFETY The crane scales have been sealed by Messrs. KERN. Shackles and hooks are sealed by Sella tape. INSTRUCTIONS The packaging is also sealed by adhesive tape. for protection against break + Broken seal obliges to purchase. Thanks for your comprehension.
4.3 Checking the original dimensions Enter the original dimensions shown on the production data sheet in the grey boxes of checklist chap. 10.3. Check original dimension of crane scales; for implementation see chap. 10.2 „Regular Maintenance“ Enter all data (date, tester, results) in the first line under „Inspection before first use“ in the checklist (see chapter 10.3) CAUTION 4.
4.5 Suspending the balance Condition The crane needs a safety bracket (1) that the unloaded crane scales 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. Suspend the crane scales on the lower hook of a crane and close the safety bracket. The crane scale’s upper eyelet should rest in the saddle (2).
5. Operation 5.1 Safety instructions Risk of injury due to falling loads! Danger Take great care when operating the crane and follow the general rules for crane operation. Check all parts (hook, eyelet, rings, rope slings, cables, chains etc.) for excessive wear or damage If faults can be seen on the safety bracket of the hook or if it is missing completely, the scales must not be used Work only with appropriate speed Always avoid vibrations and horizontal forces.
Keep an eye on suspended loads. Do not exceed the nominal load of crane, crane scales or any kind of load attachment devices at the crane scales. (example) 5.2 Loading the crane scales 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 onespot suspension.
Only use load attachment devices which guarantee a one-point suspension and where the scales can be suspended freely. Do not use too large load attachment devices which cannot guarantee a one-point suspension.
Do not push or pull Do not pull the hook horizontally Do not use multiple suspensions 19 HTS_A-BA-e-1430
5.3 Turn on/off Start-up Press on the keyboard of the balance. The display lights up and the balance carries out a selftest. The display runs through “PoUP2„ESC2“„8.8.8.88“, followed by the battery loading status (e.g. “CH5“ corresponds to a battery loading status of 50%) and the check number of adjustments. The selftest is completed when the weight value 0 appears on the display. Battery loading status: The battery loading status is represented in the form of “CH .
Switching Off Press on the keyboard of the balance. or Press on the keyboard of the remote control unit, the balance is in standby mode. 5.4 Set balance to zero In order to obtain optimal weighing results, reset to zero the balance before weighing. Unload the balance Press . In the display appears 0 (kg) and the indicator next to a lights up.
5.5 Taring Suspend preload. Wait for stability display, then press . In the display appears 0 (kg) and the indicator next to „NET“ appears. 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 crane balance and press 5.6 . Weighing Loading the crane scales. The weight value will be displayed at once.
7. Adjustment and verification 7.1 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).
7.2 Verification General introduction: According to EU directive 2009/23/EC balances must be officially verified if they are used as follows (legally controlled area): a) For commercial transactions if the price of goods is determined by weighing. b) For the production of medicines in pharmacies as well as for analyses in the medical and pharmaceutical laboratory. c) For official purposes d) For manufacturing final packages In cases of doubt, please contact your local trade in standard.
8. Error messages Error message Description Possible causes --ol- Maximum load exceeded Reduce load Check whether the balance has Capacity of rechargeable battery exhausted. been damaged Recharge battery In the „LOB“ display, the balance switches off automatically to save the rechargeable battery after 1 minute. LOb Should other error messages occur, switch balance off and then on again. If the error message remains inform manufacturer. 9. Cleaning and Disposal 9.
10. Maintenance and repair Risk of injury and risk of material damage! The crane scales are part of a hoisting device! For a safe operation please observe the following: Danger Have carried out a regular maintenance by trained specialized staff Carry out regular maintenance and care, see chapter 10.2 and 10.3 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.
10.2 Regular maintenance Initial start-up, every 3 months or definitely after 12 500 weighing processes Check all dimensions, see checklist chap. 9.2 Check the shackle for wear and tear, such as e.g. plastic deformation, mechanical damage (unevenness), notches, striation, cracks, corrosion, thread damage and torsions.
