15.11 Overload control components
ATTENTION! Overload control has been set to the correct values at the factory and it is
strictly forbidden to change its settings. FALLING HAZARD!
Overload control mechanism is located between the working platform and the platform
support (picture 21). Basket load is measured with a load sensor (1), which has 2-channel
measuring. Both channels are tared according to empty platforms weight. The sensor follows
EN 280
–standard and it can be used in applications mentioned in the standard.
Picture 21. 1: Load sensor MOBA MRW Limit, 2:
”zero load” orange indicator light
Maximum platform load has been adjusted to 230 kg. In an overload situation the use of
booms is prevented and you will hear a sound alarm and see a indicator light in the lower and
upper control panels. Use of the machine is possible again after removing the load from the
platform. The load sensor should be checked regularly for physical damage. Damage might
cause incorrect sensor values. If the sensor has to be replaced due to faults or damage, the
bolts should be tightened to 150 Nm.
There is a led indicator light in the sensor (picture 21, (2)), which allows the so called zero
load to be monitored. The light turns on when the basket load is 0 kg ±15 kg. The basket load
must be tared in every maintenance inspection by an authorized person. To tare the load
sensor you need a programming tool. The tool is available for authorized dealers and service
companies. Instructions are available from Leguan Lifts.
NEVER OVERLOAD THE MACHINE!
