ELECTRICAL SYSTEM

The series 336 trucks are equipped with a compact LTM control for the travel drive and the working hydraulic
system. The steering system is controlled via the lift LTM control.
The compact LTM control has the following advantages over the previous LTM control:
- less space required
- easier installation
- available as replacement part
- integrated freewheel diode
- integrated brake diode
- integrated regenerative braking diode
- easier troubleshooting
- improved dissipation of heat
Features of the power unit:
- N-type channel enhancement type MOSFET
- Zener diode for active overvoltage protection
- gate-source Zener diode and resistor against static overvoltage at the gate
- integrated gate resistors against internal oscillations
- insulated aluminium base plate
- longer air gaps
Regenerative braking is standard equipment for this series, which returns part of the energy generated during
braking back to the battery. The control unit and the fan are supplied with 24 V direct current via a separate
voltage converter.
Trucks equipped with optional lighting require a separate voltage converter.
