SENSOR FAULTY –
SENSING INVALID
2560 1 Consider any information on input
J3-8 Boom Retracted invalid.
Set the system as if the boom is
always extended.
The UGM has detected one of the
following failures of the boom
retracted sensor when configured
for LSI-CAN or LSI-CAN + LMI:
With no telescope functions active,
a boom retract ed sensor state
changes occur.
With Telescope In active, a boom
retracted sensor transition of HIGH
to LOW occurs.
With Telescope Out active, a boom
retracted sensor transition of LOW
to HIGH occurs.
With Telescope Out active, the
boom retracted sensor has not
HIGH for a period of 5 seconds with
at least 950mA commanded on the
function AND the Load Moment
Warning Point has been met or
exceeded.
