If you are wearing hearing protectors or
headphones during lifting operations, make sure
they do not impair your ability to hear the sound
alarms of the i4000 system.
1.4.2 Visual alarm
The i4000 system display has been equipped with a 3-colour warning light to alert the operator
and to indicate a specific action.
The flashing yellow light turns on together with the sound alarm when the load reaches the
approach alarm’s threshold, that is, 90% of the nominal capacity.
The light turns red when 100% of the nominal capacity is reached or exceeded.
This light is green under normal operating conditions.
1.4.1 Audible alarm
An intermittent audible alarm within the display unit warns the crane operator that
an intervention is necessary before the load reaches its nominal value. The default
threshold for the approaching alarm is 90% of the nominal capacity. The overload
alarm is activated continuously when 100% of the nominal capacity is reached or exceeded. The
crane operator will also be warned by the internal audible alarm when approaching or reaching
a limit that he had already defined.

YELLOW RED GREEN
The approach and overload alarm settings can be modified according to the user’s
preferences.
