interesting reading Kirley - thanks for posting. im a little confused about the operation of the dead man breaking system....
'The Class 80 unit is fitted with a standard three-position time-based ‘Deadman’ vigilance system. The pedal is normally held in the mid position and depressed every minute (timing can be varied) to prevent the equipment entering an emergency phase and applying the brakes. If the pedal is released a normal ‘Deadman’ Emergency brake application is made after a few seconds. This switch takes the form of a foot pedal placed in the footwell at the driver’s feet.'
does this mean the driver has to tip the pedal every minute to avoid the breaks being applied?
