GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
6
WRL Radius Enabled
Indicator (Green)
Indicates that the minimum boom angle limit, the maximum boom
angle limit, or both the minimum and maximum boom angle limits
are defined.
WRL Radius Warning
Indicator (Amber)
Indicates the boom radius is within 3 m (10 ft) of a radius limit
setpoint.
The warning buzzer slowly beeps when the boom radius is within
3 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.
WRL Radius Stop
Indicator (Red)
Indicates the boom 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.
6
WRL Swing Enabled
Indicator (Green)
Indicates the left and right swing angle limits are defined.
WRL Swing Warning
Indicator (Amber)
Indicates the swing angle is within 10° of a swing angle limit setpoint.
The warning buzzer slowly beeps when the swing angle is within 10°
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 10° 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 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.
WRL Swing Stop
Indicator (Red)
Indicates the swing angle is at a swing angle limit setpoint. The
warning buzzer is on (constant).
For cranes that are equipped with the WRL Lock Out Function, the
swing left or swing right crane function is locked out, depending
upon which limit is reached.
