6.1.5 Traction and hydraulic controller - LAC / 1A1
6.1.5.1 Description
The 1A1 controller, the LAC (Linde Asynchronous Control), comprises of a control card LTC (Linde Truck Control)
and a power stage for the traction and the hydraulics.
The transistors' control is performed by an electronic circuit called DRIVER , forming the interface between the power
and control parts.
The numeric control module LTC uses two microprocessors (Traction and Hydraulic) that are auto-controlled. If a fault
occurs, it is detected instantly and the control system puts the truck in safety, which can be a reduction in performance
or the halting of a controller, depending on the type of fault. The control module is equipped with a connector 1X1 of
70 pins.
