Sensor supply test

With P3248, operator can disable/enable the internal 5V supply on the PVED-
intended for testing purpose, and should be kept at Enable (P3248 set to 0) all time.
Important
P3248 set to 1 will shut down the sensor supply but not the monitoring of it. So if an operator chooses to disable this (e.i.
P3248 set to 1), the operator has to set an external 5V supply to PVED-CLS sensor supply pin (pin 11) else PVED-CLS will go to
safe state.
Important
If the operator chose to use the internal 5V in the PVED-CLS and a WAS of the potentiometer-type, remember to setup the
analogue channel compensation parameters too (P3246 and P3247).

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:
