ECS Gen. 2
Solenoid valve
block - drive
axle - 4x2 -
suspension raise
If the driver switches the bogie switch to ʻraiseʼ position,
and/or the ECU receives a ʻraiseʼ signal from a height
sensor, the ECU sends +24 V to energise the control
solenoid and drive axle solenoid.
Air can now pass from valve block inlet (1) - supply from
wet tank - to outlets (21) and (22) to the LH and RH air
bellows.
The chassis is raised to the required height.
