3. MAXIMUM POWER OF "H" MODE
When H mode is selected in the cluster,
CPU controller moves the engine accel
actuator to set the throttle lever to the full
position and sends initial current signal to
the EPPR valve to set the pump absorption
torque high. So, it is possible to maximize
the work performance by using 100
$
of the
engine power at this mode.
If the pump load becomes too high and the
engine speed drops, the CPU controller
reduces the pump discharge amount and
momentarily resets the engine speed to the
rated point through engine speed sensing.
