2.6 Warning Lights and Indicators Detailed Description
Operate with caution !
The crane is working near its maximum
load capacity.
The approach warning light (yellow) turns on when the
hook load is between 90% and 99.9% of the rated capacity
(adjustable value). This comes with an audible warning
device that is fitted inside the display unit. This light will
also turn on if you are approaching within the calibrated
approaching distance (feet, meters or degrees) of a
predetermined limit set in the limits setting mode.
The crane maximum capacity has
been reached or exceeded.
The overload warning light (red) turns on at or above 100%
(adjustable value) of the rated capacity. This light will also
turn on if you are reaching a predetermined limit (set in
the limits setting menu).
The crane has exceeded safe operational
ratings and is now in an unsafe condition.
Hoisting up and booming down functions
will be stopped if a motion cut solenoid is
connected to the system.
The lockout warning light (red) turns on at or above 100.1%
(adjustable value) of the rated capacity. Booming down
and hoisting up functions are usually blocked. The exact
operation is specific to the crane model.
