Working Range Limiter
(WRL) Radius Warning
Indicator (Amber)
Indicates the boom radius is within 3.1 m (10 ft) of a radius limit
setpoint.
The warning buzzer slowly beeps when the boom radius is within
3.1 m (10 ft) of the radius limit setpoint and changes to a fast beep
when the radius is within 1.5 m (5 ft) of the radius limit setpoint.
Working Range Limiter
(WRL) Radius Stop
Indicator (Red)
Indicates the radius is at a radius limit setpoint. The warning buzzer
is on (constant).
For cranes that are equipped with the WRL Lock Out Function, the
boom up and telescope in, or boom down and telescope out, crane
functions are locked out, depending upon which limit is reached.

Working Range Limiter
(WRL) Swing Angle
Warning Indicator
(Amber)
Indicates the swing angle is within 20° of a swing angle limit setpoint.
The warning buzzer slowly beeps when the swing angle is within 20°
of the swing angle limit setpoint and changes to a fast beep when
the swing angle is within 5° of the swing angle limit setpoint.
For cranes that are equipped with the WRL Lock Out Function, when
the swing angle is within 20° of the swing angle lock out setpoint, the
swing function commanded by the controller may be reduced or
suspended depending upon the weight of the load and the swing
speed.
Warning
Due to the free-swing characteristic of the crane’s
superstructure, the boom and load can potentially swing past
the swing angle setpoint, even if the swing function commanded
by the controller is reduced or suspended (locked out) by the
WRL. This can happen for several reasons, including how level
the crane is and environmental conditions, such as wind speed.
