In the case of reselling or hiring out, always provide the product manual together with the crane.

Proper use

The ABUS load indicator system LIS-SE is a load measurement and evaluation system designed for hoists and crane installations. The LIS-SE is intended especially for use in hoist control systems. Its main function is overload protection through evaluation of the current and voltage of the hoist motor. An optional load population recorder can be used to log the actual operating mode of the hoist. The LIS-SE is intended especially for use in pole-switchable three-phase motors.

Regulations

The installation has been built and tested according to European standards, rules and regulations applicable at the time of its manufacture. The conventions applied during design and construction are specified in the Declaration of Conformity or the Declaration of Incorporation. The conventions must also be observed for installation, operation, inspection and maintenance, as must the applicable occupational health and safety regulations.

Which provision applies in individual cases will greatly depend on the crane’s use and the national regulations. Review and observe all applicable and current regulations, including the occupational health and safety regulations. Refer also to the Declaration of Conformity or Declaration of Incorporation.

Warranty

• ABUS assumes no liability for damages that were caused by improper use, inadequately trained personnel, incorrect performance of work, nor for any changes, reconstruction or other modification of the crane or crane components which were not approved by ABUS.
• Safe operation of the crane or crane components is only guaranteed if original ABUS replacement parts are used.

Instructions regarding safety

Observe these instructions for safe handling of the crane. Special hazard notices are located in the corresponding sections in which the danger arises.

• Before commissioning, it must be checked that the wiring of the installation conforms to the wiring diagram.
• Before working on the crane, disconnect the power line and wait at least four minutes until the voltage has dissipated.
• Only have trained electricians perform the work on the crane electrical system!
• Changes that impair safety, as well as extensions and modifications, are prohibited and may only be carried out by ABUS. Opening the LIS-SE is prohibited!
• Wrong parameterisation and settings could lead to a possible overload of the crane, causing a load drop.
• If the LIS-SE is incorrectly connected, the LIS‑SE itself or other components could be damaged.

Performance features

Load indicator system LIS-SE:

• The LIS-SE is a microcontroller-controlled system for load measurement and evaluation on hoists.
• The main function of the LIS-SE is overload protection of the hoist through evaluation of the current and voltage of the hoist motor. The message of an overload can be sent visually as well as acoustically. The switching points of the overload protection can be set to maximally 110 % of the maximum load capacity. The switching points can be set variably in 2 % steps.
• Lifting the load with a sudden jolt is prevented by the switch-off of the fast lifting speed in the event of a rapid load increase.
• The LIS-SE can additionally output status or error messages.
• The load population recorder (option) shows the theoretical service life of the crane, its actual hours of use, the number of operating hours and the crane's remaining service life.
• The LIS-SE galvanically isolates the signals at the inputs from those at the outputs.
• The automatically controlled regenerative braking during lowering increases the service life of the brakes.
• The permanent monitoring of the motor current with commensurate switching of the contactors extends the service life of the contactors.
• The hoist motor always starts at slow lifting speed and switches to fast lifting speed only after a set time has elapsed, thus preventing a rapid load increase and reducing the start-up current.
• Two or more hoists can be monitored in joint operation. This does NOT correspond to the synchronization control system! The synchronization control system is a separate ABUS product.
• An inching counter prevents the lifting of the load in inching operation. When the set number is exceeded, lifting is no longer possible. Operation can be resumed by pressing the “Lower” button for at least 3 s.

Current transformer module:

• The load evaluation is carried out through the measurement of the voltage and current in the connection cables of the hoist to be monitored.
• An external current transformer module performs the measurement.
• The size of the current transformer modules depends on the rated current of the hoist motor at fast lifting speed.

Technical data

LIS-SE

Disposing of the LIS-SE

If the LIS must be disposed of:

1. Dismantle the LIS components as far as possible.
2. Observe local regulations concerning disposal and recycling.
3. Dispose of the individual parts sorted by material in an environmentally sound manner.

• Remove electronic assemblies and dispose of in accordance with local regulations for scrap electronic parts.
• The plastic housing should be recycled with plastic waste.

Operating the LIS-SE

All settings and displays in the main menu (parameter level) of the LIS are shown through parameters. Each parameter is shown on the display as a two-digit or three-digit number. Most parameters have a value that can be displayed or adjusted.

Functions of the buttons

DownUp

• Enter:

Brief pressing during input of a value or a number: jumps to the next digit.

Brief pressing within a parameter: saves the changed value.

Brief pressing during input of the code: confirms the code.

Holding pressed within a parameter: opens the display for entering the code to change the value.

Holding pressed after entering the PIN: opens the parameter level.

• Up and down arrow buttons:

In the parameter level: selects a parameter.

When entering a value: input of numbers.

Entering numbers

Note

The input of numbers always follows the same principle, regardless of whether the input concerns parameter values, the code or the PIN number. There are always only 4 digits displayed, since the display can only show 4 digits. However, larger numbers can also be entered. In this case, the digits after the decimal are pushed out of the display and are thus no longer visible.

1. Input the first digit with the arrow buttons.
2. Briefly press Enter to jump to the next digit.
3. Repeat the procedure for the input of the next digits.

Setting option:

The table shows an example of the setting options for the parameter P 6.1. For some parameters however, the setting options are also prescribed. With regard to the load capacity, 100 t can also be entered, for example.

Example P 6.1:

Setting a two- or three-digit number at the first position:

If the number changes from single-digit to two-digit or three-digit, the decimal in the display is moved by one or two places. The decimal places are then pushed out of the display, since only 4 digits can be displayed.

The input of the numbers always begins on the right with the third decimal place.

Example, single digit:

1. Enter value of 1250 kg with the arrow buttons and Enter.

Example, two digits:

1. Enter value of 10,250 kg with the arrow buttons and Enter.

P 2.3 Setting with test load (teach-in)

With this parameter the rotating field power is recorded according to a defined procedure for both the slow and fast lifting speeds. The procedure occurs in two steps. In the first step, the rotating field power is measured with empty load hook and in the second step with a test load. The LIS-SE uses these values to calculate a proportional function (load line), which in turn is used in later operation to calculate the respective current load from the rotating field power.

All subsequent steps must be completely carried out, since otherwise the setting is not completed and error messages can arise!

Note

To set the test load, a test load with known weight is required. The test load should be 80 % of the maximum load capacity.

The test load must be at least 40 % of the maximum load capacity. If a setting is made with a test load between 40 % and 80 % of the maximum load capacity, this must be noted in the test log book.

The closer the test load is to the maximum load capacity, the more accurate will be the displayed weight of the load.

Tip:

Several measurements are carried out in the following. After each measurement, the load hook can be lowered so that there is enough lifting height available for the next measurement.

Entering the value of the test load:

1. Select parameter P 2.3 with the arrow buttons.

1. Select parameter P 3.4 with the arrow buttons.
2. Press Enter briefly.

• The parameter is opened and the current value is displayed.

Next, the parameter level must be called up again in order to exit the parameter:

1. Hold Enter pressed until “Code” or “P-nr” appears in the display.

1. Open the parameter level.
2. Exit the parameter level via P 9.9.

P 3.41 Mains voltage analysis

This parameter is used for simple and fast diagnosis and measurement of the mains voltage curve at the start of fast lifting speed. The measurement is performed with the motor running, and the crane is therefore functional in this parameter and can lift/lower.

The crane should be positioned as far as possible from the feed unit of the conductor system so that the voltage drop on the conductor system is also measured.

A total of 10 values of the mains voltage are measured [in V]. At the start of the fast lifting speed, the mains voltage is measured every 50 ms.

1. Position the crane as far as possible from the feed unit of the conductor system.

P 5.0 Measuring time extension

This parameter enables you to extend the measuring time during start-up of the motor. This can be necessary, for example, due to a mains voltage that is too low, since the start-up current flows for longer than 300 ms. In this case, an overload would be interpreted after 300 ms due to the high start-up current, which is however not an overload but triggered by the lack of motor torque resulting from the insufficient mains voltage.

Note

Default setting: 300 ms

The measuring time can be extended to maximally 460 ms.

The parameter can only be accessed with a special code! Whenever adjustment of the measuring time extension is necessary, contact your ABUS Service representative. See “ABUS Service”.

Maintenance

This section applies to anyone who maintains, repairs or modifies the crane.

The end user of the crane is responsible for the selection and proper qualifications of the maintenance personnel.

Examples of qualified persons:

• Persons with comprehensive knowledge from specialist training in engineering and in the electrical systems of cranes.
• Persons with sufficient experience in the operation, installation and maintenance of cranes.

• Persons with comprehensive knowledge regarding the relevant technical rules, directives and safety regulations applicable in the respective country.
• Persons receiving regular training from ABUS.

ABUS assumes no liability for damage due to incorrectly performed maintenance work done by unqualified personnel.

ABUS recommends having the maintenance work performed by ABUS Service.

Instructions regarding safety when performing maintenance work

Observe the following safety instructions for any maintenance work on the crane with LIS:

• Switch off the mains switch. Secure the switch to ensure it cannot be turned back on accidentally.
• Unplug the mains disconnector plug from the socket on the crane panel. Secure the socket with a padlock to ensure it is not plugged back in accidentally.
• Use suitable lifting platforms and fall protection equipment.
• Adequately cordon off the operating range around the lifting platform.
• Switch off any other cranes using the same crane track or cranes working above or below the crane undergoing maintenance. Secure the switches to ensure they cannot be turned back on accidentally. Otherwise, other cranes could overturn the hoisting platform or crash into the crane undergoing maintenance.
• Notify personnel in the area that maintenance work will be performed.
• Only have trained electricians perform the work on the crane electrical system!
• Even after the emergency stop button has been pressed, life-threatening high voltages are still present in the panels.

Correcting errors on the LIS-SE

If the LIS-SE is not working or functions other than as expected, a malfunction on the LIS-SE may be the cause.

2. Press Enter briefly.
3. Set the value between 0 % and 110 % of the maximum load capacity.
4. Press Enter briefly.

• The value is saved.

Entering the setting with test load: Teach-in (P 2.3).

With this parameter the rotating field power is recorded according to a defined procedure for both the slow and fast lifting speeds. The procedure occurs in two steps. In the first step, the rotating field power is measured with empty load hook and in the second step with a test load. The LIS-SE uses these values to calculate a proportional function (load line), which in turn is used in later operation to calculate the respective current load from the rotating field power.

All subsequent steps must be completely carried out, since otherwise the setting is not completed and error messages can arise!

Note

To set the test load, a test load with known weight is required. The test load should be 80 % of the maximum load capacity.

The test load must be at least 40 % of the maximum load capacity. If a setting is made with a test load between 40 % and 80 % of the maximum load capacity, this must be noted in the test log book.

The closer the test load is to the maximum load capacity, the more accurate will be the displayed weight of the load.

Tip:

Several measurements are carried out in the following. After each measurement, the load hook can be lowered so that there is enough lifting height available for the next measurement.
