System Description



The ABUS LIS-SV load indicator system is a compact universal load recording and evaluation system for hoists and cranes. The LIS-SV operates on the principle of microprocessor-controlled evaluation of signals from strain gauges installed on each hoist to be monitored in the form of measurement axles, measurement bolts or similar devices" The load calculated can be indicated using an ABUS type LAZor GLZ load indicator. The basic LIS-SV module with integrated load population recorder also offers the optional feature of recording and evaluating the actualoperating conditions of a crane system in accordance with FEM 9.755. As a standard feature, the maximum load of up to three



hoists may be monitored. See a/so information on parameter 5.10 in Section 10. ln addition, the system monitors the total carrying capacity of a crane system. The functions available include "part load switch", "totalization and indication" and "load population recorder" (optional). The unit can easily be adapted to a variety of load signal sources and is therefore a highly functional, universal unit. Special features: o overload shut-down function o load evaluation possible for three hoists . total load measurement and monitoring for three hoists o LAZ andlor GLZ load display (OPTIONAL) o load population recorder in accordance with FEM 9.755 (optional) o second shut-down point (adjustable in 2 % steps)

Use for the lntended Purpose



The ABUS LIS-SV is designed for use in the control systems of hoists of all types not subject to the risk of



tipping-over. It is intended for installation in a closed housing and for use under the conditions listed in Section 4 below. Special investigations must be made concerning the



suitability of the unit for use in other conditions and modes of operation. lt may be necessary to obtain the manufacturer's approval for any deviations.

Notes on warranty



ABUS assumes no liability for any loss or damage caused by use other than for the intended purpose or any work performed improperly or by unauthorized persons. ABUS assumes no liability as towards third parties.



Attention! lf you modify any components under your own responsibility, assemble components other than in accordance with the installation



instructions and/or plans or use any compo-



nents other than genuine ABUS components, ABUS will be released from any warranty obligations for the entire equipment.



ABUS assumes no liability whatsoever for any damage to cranes or hoists which may be caused by the incorrect setting of the unit.



It is recommended that repair and maintenance work should be carried out by the ABUS service department.

Functions General: For load recording and evaluation, the LIS-SV load



a load signal transmitter (measurement axle, measurement bolt, etc") installed on the hoist. For load evaluation on two or three hoists, the signals from the measurement axles of LIS-FC or SV units are converted into a frequency signal proportional to the load measured. This ensures interference-free transmission to the master LIS-SV. The load sensor receives a highly constant 10 V DC power supplyfrom the LIS-SV or LIS-FC and returns



ture shut-down eaused by dynamic load peaks. lf the static load measured exceeds 110 "/o of the rated value, the two output relays are shut down.



indicator system needs



a load-proportional voltage signal to the LIS-SV I Lts-Fc. ln the LIS-SV unit, the signal is amplified and evaluated



by a microcontroller system. lf the preset load limits are exceeded, hoist movement is stopped or other appropriate action is initiated using lay contacts. ln addition, the load signal is processed



display on a load indicator and fed to the LAZ load indicator in the pendant control (and/or a large load display). The LIS-SV unit monitors both the individualload signals and the total load measured. Either the load measured by one of the three load measurement devices or the total load may be displayed. .-.rr



2.1



b)



Dynamic overload shut-down. lf any dynamic peak exceeds 125 % of lhe rated value, the output relays for the two hoist speeds are immediately shut down. The control algorithm is specially programmed for hoists and ensures that the hoist is not shut down by dynamic load peaks below the limit.



c)



Shut-down on sudden load increase. lf the load increases too rapidly, the relay for the main lifting speed is shut-down. The relay is only re-activated when the load has ceased to increase, provided that the maximum load has not been exceeded. This function prevents rope breakage as a result of lifting an excessive load with a loose rope at main



lifting speed. Also, excessive force on the rope is prevented if the crane hook is suddenly blocked. Note: Even in the event of an overload shut-down,



the load may be lowered at any time. When the load has been lowered (load below 90 % of static load threshold), the overload shutdown is reset"



Overload Shut-Down



Depending on the system configuration, lowering is only possible with individual or joint operation of the hoists.



The LIS-SV unit monitors up to three hoists for eom* pliance with their maximum load capacity rating and the maximum load capacity of the entire system" Overload shutdown thresholds can be set between 0 and 110 % of rated load using the DBE operator terminal (see list of parameters in Section 9). The values given in this section are based on the standard setting of 11Oo/"" The LIS-SV is equipped with two relays for enabling the



main and precision lifting speed. lf the overload thresh-



old is exceeded, these relays shut the hoist down. At re same time, the load indicator display flashes at inrervals of one second. lf the unit is used for monitoring



more than one hoist, the other hoists are also shut down if the overload threshold of one hoist



is



exceeded"



The unit implements three types of overload shutdown function:



a)



Static overload shut-down. Static loads must not exceed 110 "/" of the rated value. The actual load value is averaged over the measurement time and compared with the threshold. This prevents prema-

Part-Load Switch



ln some applications, another shut-down point below the rated load is required in addition to the overload shut-down. This may be the case if part of the hall structure is not designed for the entire load capacity of a crane system. The LIS-SE allows the user to set an additional shutdown point (which can be adjusted via parameter 4.40 - 4.43)" As soon as a signal is available at input EA of the unit, the relays for lifting movement are tripped when the set value is exceeded. The unit is then switched to the overload mode. A current transformer module with an additional switching relay may be used for more complex applications. The switching point for this relay may be set to any value between 0and 11Oo/oof raled load capacityusing parameter P 4.5.

FEM Groups



The EU machinery directive ealls for precautions to be taken to prevent risks caused by fatigue and ageing on therefore been taken in order to achieve safe working periods (S.W.P). Cranes and hoists are subdivided into various groups in accordance with FEM 9.511. The operator of a standard hoist is responsible for ensuring that the actual operating conditions of the hoist are recorded and documented in the test book at least once per year. ln the course of regular inspection, the inspector must verify and determine whether the hoist is still being operated within its safe working period.



Load Population Recorder (optional)

the actual operating conditions of a hoist can be recorded. ln addition to the total running time
