6.1.6 Traction start-up conditions (Validation)
The LAC needs some information to start the traction. This information is associated with the operating
status of the electric steering and the drivers position in the truck.
- The first LAC validation condition is an LES electric steering in good condition, controlled by the traction
in terminal 1X1:35. The signal sent by the steering is a negative coming from the terminal 3X1:8.
- The second condition, to obtain the traction, is linked to the Platform/ guard rail/operator presence / tiller
base (inputs of terminals 1X1: 31 / 53 / 8 / 7 of the LAC).
In the table:
- Value 1 means that the input is linked to the battery negative
- Value 0 means that the input is disconnected
- A "-" means that the value can be 1 or 0
Reaction of the truck when you go from one status (from 1 to 8 in the table) to another:
Truck status Action Reaction
- The truck moves to status 2, 7 or 8 release the tiller - apply the electrobrake.
(1X1:7=0)
- The truck moves to status 7 raise the guard rail - if the accelerator is released in neutral position then
(1X1:53=1) reactivated move to status 8.
- The truck moves to status 8 lower the guard rail - move to status 7.
(1X1:53=0)
- The truck moves to status 7 or 8 leave the presence - the motor brakes, then when the truck halts, the brake (1X1:8=0) is
applied, you go back to status 5.
- The truck moves to status 7 or 8 raise the platform - the motor brakes, then when the truck halts, the brake (1X1:31=0)
is applied, you go back to status 4.
