Operating instructions These operating instructions are intended to put you in a position to operate the crane safely and utilize the reliable usage options that it provides. The instructions also provide information about the function of important components and systems. Certain expressions are used in these operating instructions. In order to avoid misunderstandings, the same expressions should always be used. These operating instructions have been translated to be best of one’s knowledge. Liebherr-Werk Ehingen GmbH assumes no liability for translation errors. The German version of the operating instructions is solely applicable for factual accuracy. If you find any errors or if any misunderstandings arise when reading these operating instructions, please contact Liebherr-Werk Ehingen GmbH immediately. DANGER Risk of fatal accidents if crane is not operated correctly! Incorrect operation of the crane can result in death or serious injury! Only authorized and trained expert personnel are permitted to work on the crane! The operating instructions and on-site regulations and specifications (such as accident prevention regulations) must be followed. Using these operating instructions: – makes it easier to become familiar with the crane – avoids problems due to improper operation Observing these operating instructions: – increases reliability in use – extends the service life of your crane – reduces repair costs and downtime Always keep these operating instructions handy in the driver's or crane cab. The operating instructions belong with the crane! Only operate the crane if you are well familiarized with the equipment, and always follow these operating instructions. Note If you have received additional information from us relating to the crane, such as technical information bulletins, instructions and / or supplements to the operating instructions, then this information must also be observed and kept with the operating instructions. If there is anything in the operating instructions or the individual chapters that you do not understand, please contact us before starting the relevant work. The information and illustrations contained in these operating instructions may not be copied or distributed, nor used for competitive purposes. All rights are expressly reserved in accordance with copyright laws. All accident prevention guidelines, operating instructions, etc. are based on destined use of the crane. Destined use The destined use of the crane consists solely in vertical lifting and lowering of free and non-adhered loads, whose weight and center of gravity are known. To do so, a hook or hook block approved by Liebherr must be reeved on the hoist rope and it may only be operated within the permissible crane configurations. Driving with the crane, with or without an attached load is only permissible if a corresponding driving or load chart is available. The crane configurations intended for it and the safety conditions must be observed according to the corresponding operating instructions. Any other use or any other exceeding utilization is not destined use. Part of destined use is also adherence of required safety regulations, conditions, preconditions, crane configurations and working steps as noted in the crane documentation (operating instructions, load chart, job planer). The manufacturer is not liable for damages, which are caused by non-destined use or improper use of the crane. Any associated risk it is carried solely by the owner, the operator and the user of the crane.

1 Error recognition - LICCON computer system 1.1

General Note The monitor illustrations in this chapter are only examples. Please note that all illustrations in this chapter are only examples and might not exactly match your crane. Faults or errors occurring in one or more modules will be displayed at the system level of the BSE test system (chapter 20.10). The error stack of the BSE test system may be used to display the error description of error(s) which have occurred. See chapter 20.10.

1.2

Locating and rectifying errors The crane operator can use the error diagnostics to immediately identify any errors that may have occurred. The error can in many cases be quickly located and rectified using the error description from the “BSE test system”. If the LICCON-Error-Code displays an error: Consult the section “Error determination” (chapter 20.10) of the BSE test system. If the monitor display is defective: Consult the section “Monitor errors”. Note Consult LIEBHERR Service. If the assistance of LIEBHERR Service is required, please always provide the following information: – Crane type – Crane number – Complete error number and any error message displayed on the monitor – Application conditions of crane – Action during which the error occurs – Frequency of error If the crane operator cannot rectify the error himself: Consult LIEBHERR Service.

1.3

LICCON-Error-Code (LEC) The LICCON-Error-Code describes two possible error classes: – System errors – Operating errors The error code is displayed in the superstructure (error determination display of “BSE test system”). In addition, all errors are listed in a separate error list (error text, cause, remedy). The structure of the error code is based primarily on a 6 digit error number as well as the given error class description.

Function key System “F1” Press function key F1 on the BSE test system start screen, illustration 3, to access the “system level”, illustration 4. The system level uses a hierarchical structure with the MPC at the top and the DSP´s arranged underneath in parallel. Each DSP is subordinate to four LSB buses. Note The system level provides the crane driver with a quick overview of any current system errors or faults. If a daily code is not entered (service level 0), it is only possible to use the cursor (function keys F1 – F4) to select modules or stations. A supplementary text 1 for the selected module or station is displayed above the function key line. All modules, LSB´s and stations at system level are color-coded. Each color has a certain significance. In addition to color-coding, each station may be displayed as a static or flashing icon. Note The state of a particular module, LSB or individual station may be determined by its color and whether the station is static or flashing.

Hardware error A short-circuit between LSB and ground, or between LSB and a 24 V bus circuit, represents a hardware error. Consequently all bus participants will become faulty. Note All participants on the faulty bus circuit are displayed “blinking red”. Error determination Proceed according to the following sequence to determine the hardware error: – Pull the faulty LSB bus plugs (for example: LSBE/LSB5) from the corresponding circuit board (-A411). Note: On the LICCON monitor all LSB participants connected to the faulty LSB bus will continue to blink red after the plug connectors are detached. – Check the power supply 24 V (green LED) 2. Note: The green LED 2 lights up when the power is connected. – Check data transfer (red LED) 3.

3 Error determination Malfunctions in the LICCON computer system generate error messages. A distinction is made here between operating errors and system errors. System errors can still be subdivided into: – Active system errors Errors which are present continuously (Example: cable break, sensor defective, etc.). Marked with a “+” – Inactive system errors Errors which only occur momentarily (Example: loose contact, temporary sensor failure, etc.) Marked with a “-” Note Should an error occur during crane operation, the error type (operating or system error) and error path are shown red in the “horn” icon on the function key line. If multiple errors occur, the error type and “faulty” module having the highest priority is displayed.

Error stack Each BSE test system module (for example: MPC, DSP0, ...) has a memory for up to 15 errors. All errors are displayed together with their error number and stored and documented in the relevant error stack. – If the error stack of one module is full (15 errors), inactive errors will be overwritten by new active errors. – If only active system errors are present in the error stack it is not possible to store any additional system errors in the error stack. – If the error stack is filled with active system errors, a system error will be overwritten if an operating error occurs. – If an error is still present or the cause of error has not been rectified, a new active error message will be generated and displayed if the error occurs again, i.e. with a new date and time. CAUTION Deleting errors in the error stack! When the ignition is turned off, all error messages (active and inactive) are deleted in the error stacks. Be careful when turning the ignition off.

3.1.1

Determining errors from the Operation, Telescoping, Configuration, Support programs Procedure If a system error or operating error occurs, an error message will appear in the “Horn” icon above function key F8, for example B:DSP0.

1 Remote diagnostics* LWE remote diagnostics allows LIEBHERR cranes to be serviced remotely in the event of an error. The remote diagnostics module (GSM module) must be connected to the LICCON computer system of the crane. Once the connection between the crane and service point has been established, the data is transferred from the “REMOTE DIAGNOSTICS SYSTEMS” to the computer located at either LIEBHERR customer service or at one of the LIEBHERR service points. Worldwide remote diagnostics coverage is possible if the LIEBHERR customer service or LIEBHERR service point is provided with full access to the crane's functions. In addition to the “GSM connection”, a telephone connection must also be established with the LIEBHERR customer service or LIEBHERR service point to facilitate communication with the crane driver and issue instructions as required. Always ensure that the instructions given by the LIEBHERR customer service or LIEBHERR service point are followed precisely.

Activating the remote diagnostics module or remote diagnostics device DANGER Risk of accident! Remote diagnostics should only be used by authorised persons. Several following conditions must be fulfilled to ensure trouble-free remote diagnostics and call setup to the GSM module. Note The WL634 cable was already fastened to the crane in the factory works and connected to the COM3 port at the rear of the monitor and the GSM module. The power supply of the GSM module must be plugged into the 24 V roof panel socket 72 when the “REMOTE DIAGNOSTICS SYSTEMS” is switched off.

Ensure that: – the power supply of the GSM module 7 is plugged into the 24 V roof panel socket 72. – the telephone number of the data service is known – the PIN code request of the SIM-card is deactivated The SIM-card offers three different telephone services, each of which has its own telephone number: – Voice – Fax – Data Note Deactivate PIN-Code request! A standard mobile telephone is required to deactivate the PIN-code request. Insert the SIM-card into this mobile telephone and switch off or deactivate the PIN code request. The factory-fitted SIM-card in the GSM module will expire after a period of two years. The inserted SIM-card could suddenly also stop functioning. Note In this case order a new SIM-card. When ordering a new SIM-card, send the following information to the provider to ensure you receive a system-compatible SIM-card. This is the only way of ensuring that the remote diagnostics will continue to function correctly. The “new” SIM-card must have the following characteristics. Required SIM-card characteristics: – Voice-data card – CSD and voice transmission – the Siemens MC45 GSM module (modem) will be used

Telephone number of the data service (crane

___________________________

operator): (please enter telephone number here) Call the appropriate LIEBHERR customer service point (CS-point) by mobile telephone. Inform the customer service employee of the new telephone number for the data service. The CS point calls the “crane” using the telephone number of the data service. The Status LED 1.1 on the GSM module 1 will flicker to indicate the call setup to the crane driver, illustration 1.

Carrying out a remote diagnostics Once the connection is successfully established, the LIEBHERR customer service employee can access the crane's “REMOTE DIAGNOSTICS SYSTEM” using the GSM connection between his PC and the GSM module. Note Access to the “REMOTE DIAGNOSTICS SYSTEM” by LIEBHERR-customer service occurs in the “background”. This is not noticed by the crane driver. DANGER Increased danger of accidents! The crane driver continues to have unrestricted use of all crane functions and operating screens during the complete remote diagnostics procedure. Permanent telephone contact must be maintained with the LIEBHERR customer service employee during the whole of the remote diagnostics. Execute all crane movements with the utmost care, lowest possible acceleration and minimum speed. If necessary consult the LIEBHERR customer service employee. Follow all instructions given by the customer service employee.

1.4

Identifying errors The remote diagnostics system can only identify static, electrical errors which are sampled using a timebase greater than 2 seconds. If an error only appears sporadically when working with the crane: Leave the crane switched on. Result: – LIEBHERR customer service can call the crane using the remote diagnostics system in order to locate the error. Troubleshooting Data connection with the crane cannot be established? The data connection has failed. Check the interface settings using the BSE configuration tool, see next section.

Switching the interface using the BSE configuration tool The COM3 interface must be configured in the BSE configuration tool in order to permit remote diagnostics. The COM3 interface is usually preconfigured when the crane is shipped from the factory. Note If a remote diagnostics connection cannot be established, check the interface settings in the BSE configuration tool and if necessary change it to COM3. Procedure Switch on the ignition to access the BSE configuration tool. Turn the ignition switch to position 0. Result: – the crane engine is switched off – the LICCON computer system is shut down Press and hold down function keys “F2” and “F3” , then turn ignition switch to “position 1”. Result: – the BSE configuration tool starts up If the Ethernet interface has been configured, illustration 2: Press function key “F1” . Result: – the interface is switched to COM3 If the COM3 interface has been configured, illustration 3: Press function key “F8” .

1.1

Finding the worn disk brake pad You can find the worn brake pad via the diagnostics plug -X98 70 – which is in the center console. Make sure that the cover of the center console is open: – Make sure that the diagnostics plug -X98 70 is easily accessible – Prepare the multimeter for diagnostics Note Carry out the diagnostics for each brake pad individually. Connect the multimeter for the diagnostics according to the wiring diagram. The current determined with the multimeter provides information if the inspected brake pad is OK or if the brake pad is worn, or an electrical problem is present in the diagnostics circuit. During the diagnostics of the disk brake pads, always check all brake pads.
