Power Boost, CX130/CX160
1) Increases power when more force is required for digging operations.
2) By pushing a button, the main relief pressure is increased for 8 seconds, in H and S
mode.
3) Power Boost works at all times in L mode.
Note: The controller needs a RPM signal for Power Boost.
When the one-touch power boost switch is pressed ON (H and S mode), the signal enters in
the main controller. 24v is sent to a solenoid valve from the controller and the solenoid valve
switches. Pilot pressure enters the main relief valve and the pressure setting increases.
“POWER UP” is displayed on the monitor. The increase in pressure is activated for 8
seconds. The instrument panel will display “Power Up”. Even if the power boost switch is
pressed for a long time, the pressure setting increases only for 8 seconds. Power boost can
not be reactivated until the 8 second time frame has passed and the switch pressed again.
In L mode power boost is active full time.
When the travel or the hydraulic option pressure switch closes.(ON) the controller will turn off
the power boost solenoid.
The power boost solenoid is in the six solenoid valve located in the pump compartment.
