7.7 STEERING DEVICE AND PROGRAM CHANGES
Different steering devices with different programs can be used together with the PVED-CLS. The PVED-CLS will lock
a steering device, when a vehicle speed threshold of P3250 is exceeded (i.e. the PVED-CLS will ignore any steering
device change messages of lower priority, if the vehicle is traveling faster than the value in P3250). If any steering
device change messages of a higher priority than current steering device are sent, the PVED-CLS will change to that
steering device.
The priority order, for steering devices is as follows:
1. Steering wheel (STW)
2. Auxiliary steering device (AUX)
3. Auto-guidance
Below the threshold, specified by P3250, it is allowed to switch between any steering device programs, no matter the
priority. Above this threshold, steering device program cannot be switched to the one with lower priority, only a steering
device with a higher priority is allowed.
The complete PVED-CLS Steering mode selection state machine is shown in chapter 3.2. Similar to the steering device
lock, the PVED-CLS will lock a steering program (AUX or STW), when a vehicle speed threshold of P3251 is exceeded
(i.e. the PVED-CLS will ignore any steering program change messages, if the vehicle is traveling faster than the value in
P3251).
The state machines for Steering wheel, AUX and Auto-guidance steering device are shown in chapter 3.3, 3.4 and 3.5.

7.8 VEHICLE SPEED SETUP
When driving in auto-guidance mode at a low speed, the spool movement will be disabled, for safety reasons, when the
vehicle speed goes below the threshold specified P3252. The resolution is 1
x
10m/h = 10 meter pr. hour.
Important
This parameter is valid for all programs (i.e. AUX, Auto-guidance and Fast-steering).
