In case the load limiting device comes into operation, follow the path:
u click on the icon “Current Crane”
u click on the icon Display/change DMU data sheet
- The software loads the data in DMU, you have to wait a few seconds for this operation.
u The twelfth parameter which can be displayed contains the words: “jib end-of-stroke nal value”
(see page 16).
- A numerical value appears: decrease this value (decrease each attempt by 5 points)
u send a data sheet to DMU,
u run a test, after a minute from the transfer of data.
The electronic stop position of the jib opening movement is advanced.
u Reduce the value further in case there is still the intervention of the load limiting device.
Note: this function is turned on after 1 minute from DMU startup.
Practical functionality check: When operating the crane second boom, the DMU must emit two beeps
when you exceed the angle of 30° above the horizontal line, both with a rise and descent manoeuvre.
By operating the jib, the DMU must emit a beep when passing close to alignement to the 2nd boom,
both with a rise and descent manoeuvre.
