DIAG++ Operator's Guide
The following tick-boxes are provided for further Lift Axle / Traction Help control:
Traction Assist Continuously:
If ticked then system assumes any switch used for lift axle control is of "permanent" type.
With a "permanent" switch type, if the axle has subsequently dropped again because an overload or speed limit
has been exceeded then the axle will re-raise automatically should that limit then be subceeded.
Traction Assist Once:
If ticked then system assumes any switch used for lift axle control is of "momentary" type.
With a "momentary" switch , if the axle has subsequently dropped again because an overload or speed limit has
been exceeded then the axle will not re-raise unless the switch is activated again.
Once a momentary switch activation has been accepted there is a 30 second "damping" delay on accepting any
subsequent activation to avoid the lift axle dropping before it is fully raised.
Allow Disable Lift Axle:
If ticked then system always assumes switch is "momentary" and will disable (drop) all lift axles until the system is
next re-powered (ignition 'off').
Disable Lift Axles Shutdown by Brake Pedal:
If ticked this disables the dropping of any raised lift axle(s) via a brake pedal signal (i.e. 3 presses (of between 3.0
to 6.5 bar pressure) in 8 seconds).
Disable Traction by Brake Pedal:
If ticked this disables Traction Help activation via a brake pedal signal (i.e. 3 presses (of between 3.0 to 6.5 bar
pressure) in 8 seconds and vehicle is loaded).
Note:
1. Once a Traction Help Brake Pedal activation has been accepted there is a 30 second "damping" delay on
recognising a subsequent activation to avoid the lift axle dropping before it is fully raised.
2. Brake Pedal activation can only enable Traction Help (so no disable of Traction Help via brake pedal).
