Example steer axle lock (AUX 0-3)
The following screen will appear, modify the values as
required.
Lock above:
Speed at which the steer axle locks
(default 25 Kph)
Unlock:
Speed at which the steer axle unlocks
(default 20 Kph)
Lift axle dependence:
The steer axle is set to lock and
unlocks when the front axle is lifted in
order to maintain turning circle.
Invert steer axle lock
This function will reverse the values as stated above in
the steer axle lock.
By default this function provides 24 V to lock a steer
axle, 0 V otherwise.
You can invert the output to get 0 V to lock, 24 V
otherwise.
Which output type you need depends on the locking
device / pneumatic installation.
This 'Inverting' of the output can be selected in two
places:
1. Here in this screen -> is usable with all ECU software
versions, but inverts only the output of this function. If
you don't want to use further control inputs (or cannot
because not available) you should use this option.
2. In the main AUX screen -> only usable with ECU
software version B407 upwards. This option offers the
advantage that related control inputs also create an in-
verted AUX output. Example: automatic steer axle lock
function 'high' or reversing 'high' (e.g. Super AUX B).
Result: In both cases you get 0 V output to lock.
Important: Only use one of the 'inversion' options!
Otherwise you may get unexpected results!
Special case for speed setting:
If you set both speeds to '0' the function only locks
depending on the lift axle position or related control
inputs. Speed no longer has an influence!
Steer axle lock settings information
Steer axle lock function can be controlled / extended by
several inputs.
It is possible to lock the steer axle for example on the
following events:
- Reversing
- Demand signal(s) from a switch mounted in the cab
or on the trailer panel
- Depending on the front lift axle position
- Depending on the speed thresholds
Note: AUX is always active during ABS events
OR
AUX output will change status if steer lock function OR
any of the related inputs are active.
AND
AUX output will change status, if all related inputs are
active.
24 V
Standard output: Function AND / OR logic HIGH ->
24 V to solenoid, otherwise 0 V.
0 V <<Don't use this option if you intend to use the
invert option in the steer lock function>>
Inverted output: Function AND/OR logic HIGH-> 0 V to
solenoid, otherwise 24 V.
*The output level can be adjusted independently of
input use!
*Possible inputs: Super AUX A / B / C custom, general
purpose input (GPI) AUX 4 / 5
