AUTOMATIC TRAVEL SPEED CONTROL
If the automatic travel speed control switch is set to the "OFF" position, the travel motor will run in the I-
speed (low speed) range. If the selection switch is set to the "I" position, the travel motor will run in the II-
speed (high speed) range. If the selection switch is set to the "II" position, the e-EPOS controller will
monitor the main pump discharge pressure and automatically select the "ON" - "OFF" status of the II -
speed travel solenoid valve based on the travel load. The travel speed is changed between the I-speed and
the II-speed mode.
The travel load is monitored by the two pressure sensors in the discharge lines of the front (upper) and rear
(lower) pumps. When the travel load is high (pressure over 300 kg/cm
2
(4,300 psi) the solenoid valve is
turned "OFF" and I-speed (low) is selected. In the case when the travel load is low (pressure under 160 kg/
cm
2
(2,280 psi), the solenoid valve will be turned "ON" and the II-speed will be selected. But, if the engine
speed control switch dial is set below approximately 1400 rpm, the travel speed will be set to I-speed
mode.
