ECONOMY MODE
In Economy (ECO) Mode the crane software will control the
throttle command to the engine over J1939. Based on the
state of the crane and inputs from the throttle pedal and the
Increment/Decrement Throttle Switch, ECO mode will
reduce the throttle command when crane functions are not
being used. This is intended to encourage the operator to run
crane functions with enough power provided by the engine
and reduce the fuel consumption when the crane is not doing
any work.
When ECO mode is allowed to change the throttle command
the crane operator will observe the following:
• When any crane function is being commanded from
approximately 0 to 15% of joystick input the software will
i n c r e a s e t h e t h r o t t l e c o m m a n d f r o m i d l e t o a
predetermined throttle command defined by the
operator.
• When no crane functions are being commanded for
approximately 3 seconds, the ECO mode software will
reduce the throttle to idle.
Terminology
Requirements
ECO mode can be enabled by the crane operator on the
Operating Display (ODM). The default is for ECO mode to be
disabled when shipped from the factory. Once enabled, the
system stays enabled until disabled through the ODM.
NOTE: ECO mode stays disabled (or enabled)
independent of ignition key cycles and disconnect
switch cycles.
The ODM screen that is used to enable ECO mode must
contain the following information:
• Actual throttle command to the engine
• ECO mode Throttle percent setpoint
• ECO mode status (enabled, disabled, active, and
inactive)
When enabled the throttle setpoint will be set to the ECO
mode Throttle percent setpoint unless the operator had
previously set it to a higher value using the Increment /
Decrement switch.
The operator can increase the throttle command using the
throttle pedal independent if ECO mode is active or inactive.
