This fault code is a CALM Length Fault.
The N11 can appear when there is a variance in the boom
length reading between the two
length sensors or one of the length
sensors is damaged inside the cable
reeler.
To diagnose: inspect the cable reeler to ensure
the cable wire is
extending/retracting and the stow
switch is triggered when fully
retracted. Fully retract the boom,
then fully extend the boom and
check if the error continues to
occur. If the error continues to occur
contact your local EQSS
representative to repair or replace
the cable reeler.
