Optional Overload Sensing System
The hoist can be equipped with an overload sensing
system, OSD 5. The system indicates when the car is fully
loaded and prevent operation in an overload condition.
Load cells are built into the pull rods connecting the
machinery to the car structure.
When the rated load is exceeded the control circuit will be
switched off to prevent the use of the hoist. At the same
time a red LED light is activated.
When an ALC is installed, fault code F4 will be displayed
in case of overload.
Note that software of at least version 3.50 must be used
for ALCII functionality.
If software is older than version 3.50 on ALCII, it must be
connected as relay control, and not as CAN.
