GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
4
A setting of 100% results in the crane function moving at full
rated speed relative to the position of the controller. A setting
of 75% results in the crane function moving at 75% of full
rated speeds throughout the range of the controller.
Adjust the speed of a controller function by doing the
following:
1. Using the Jog Dial or Arrow Buttons on the Navigation
Control Pad, select the controller function icon that is to
be adjusted (icon will turn orange).
2. Press the Jog Dial or OK Button to make the controller
function icon active (icon background will turn gray).
3. Using the Jog Dial or the Up/Down Arrow Buttons, adjust
the percentage to the desired setting.
Adjustments are made in 1% increments/decrements.
To quickly make large adjustments, hold down the Jog
Dial while rotating it.
4. Press the Jog Dial or OK Button to accept the new
setting.
Select the Reset All icon (5, Figure 4-162) on the Controller
Speed function screen and press the Jog Dial or the OK
Button to set all function speeds to the factory default setting
of 100%.
NOTE: A crane function speed can be set to 0 (zero) to
prevent movement of that function. Crane functions
set to a speed of 0 cannot be enabled by way of the
related Enable/Disable Switch.
This is useful in a situation where, for example, a
hoist is wound with rope and the rope is tied-off at
the hoist. The operator can prevent that hoist from
operating by setting its speed to 0.
ECO Mode
Select the ECO Mode icon (1, Figure 4-163) under the User
Settings Menu Group to show the ECO Mode function
screen.
The Economy (ECO) Mode function offers the operator a
convenient way to reduce noise and fuel consumption during
craning operation. ECO Mode does this by automatically
increasing the engine speed to an operator specified engine
working speed when craning functions are operated and
then decreasing the engine speed to idle speeds when no
craning functions are operated.
The ECO Mode function screen (Figure 4-164) allows the
operator to set the ECO Mode function to on or off. The
function screen also allows the operator to specify the
lengths of time of crane function inactivity before the crane’s
engine speed is reduced from the working engine speed to
the two idle speeds.
The ON/OFF icon (1, Figure 4-164) is used to set the ECO
Mode function to on or off.
The Idle Speed 1 Time Delay Setting (2) is used to specify
the period of time the craning functions must be inactive
(controllers in neutral position) before the engine speed is
reduced from the operator specified working engine speed to
the idle speed of 1200 rpm.
The Idle Speed 2 Time Delay Setting (3) is used to specify
the period of time the craning functions must be inactive
(controllers in neutral position) before the engine speed is
reduced from the operator specified working engine speed to
the idle speed of 750 rpm.
The Current Engine Speed icon (4) indicates the current
engine speed in revolutions per minute.
The Fuel Usage Rate graphic (5) indicates fuel usage rate in
the selected unit of measure.
