1.4.1 Audible Alarm
1.4.2 Visual Alarms
If you are wearing ear protection safety devices
or music earphones during crane operations, make
sure that they will not impair your ability to hear
the audible warning signals of the i4500 system.
The display of the i4500 system has been equipped with up to 3 warning lights to
warn the operator and signal for a specific course of action.
A yellow light will blink along with the audible alarm when the load reaches the
threshold point of the approach alarm (at 95% of the rated capacity).
A red light will illuminate when the rated capacity has been reached or exceeded.
WARNING
LIGHT
YELLOW REd GREEN
An intermittent buzzer located in the i4500 system display warns
the crane operator to take specific course of actions at the approach of
the rated capacity. The threshold of the approach alarm has been fixed
at 95% of the rated capacity. The buzzer will sound in a continuous way when
the rated capacity is reached or exceeded (≥ 100%). Personnel in the danger zone
are warned by an external buzzer so that they can get out danger when the rated
capacity limiter is activated or overridden.
The crane operator will also be warned by the audible alarm when an operational
limit is activated and reached.
