3) Operation
When the starter motor switch is positioned in the "ON" position, 1st speed is selected by default.
Each time the speed switch is pressed (2), the electronic control box (3) registers a signal (IN1: 0 volt).
The electronic control box changes travel speed in the following way I ® II, II ® I and transmits the modifications
to the control screen (LCD).
Travel speed I selected
The output from the travel speed change solenoid valve (8) electronic control box (OUT) is deactivated (1st
speed).
Travel speed II selected
1. When pressure P1 or P2 is lower than 40 bar (4 MPa) at the electronic control box output (OUT), the travel
change speed solenoid valve is deactivated (1st speed).
2. When pressure P1 or P2 is higher than 40 bar (4 MPa) at the electronic control box output (OUT), the travel change
speed solenoid valve is activated (2nd speed).
When the attachment controls are operated, the electronic control box output (OUT) from the travel speed change
solenoid valve cannot be activated or deactivated.
3. When the travel pressure is higher than 260 bar (26 MPa), travel motor displacement change spool is pushed back
and the swash plate angle is in high displacement (1st speed).
4. Travel speed II can be forced (for cleaning tracks) by holding the speed control switch pressed for over 2 seconds
(IN1 = 0 volt).
