2-5 MAIN FEATURES OF CONTROLLER 1. Regenerative system (accelerator off) When the vehicle travels with the accelerator off, a braking force produced by the motor generates electricity, which is retrieved by the battery. The working of the regenerative system extends the available operation hours and the service life of brake linings. At the same time, the regenerative system improves the travel speed controllability and stability because it allows the operator to use the soft braking force exerted by the motor. Even if the direction lever is at the neutral position, the regenerative system will function when the accelerator is off. 2.
Regenerative system (brake pedal depressed) Regenerative system is operated when the brake pedal is depressed as well, which allows to extend the available operation hours and the service life of brake lining. Even if the direction is at the neutral position, the regenerative system will function when the brake pedal is depressed. 0 1 2 3. Regenerative system (switch back) The switch back operation (It means the directional change during traveling) also regenerate electricity like the previous model. Furthermore the AC controller in the new model has no contactor for traveling so that the switch back operates smoother than before. 3 4.
Power select function Three traveling and material handling modes are available from a selection switch on the multiple display: H (high power) mode, P (power) mode, and S (standard) mode. 4 5. Advanced power select function (option) The advanced power select function allows the operator to select a traveling power mode and a material han- dling power mode independently from each other. It also allows the operator to define a mode other than H, P, and S. 5 6 6. Power keep function The power keep function maintains the vehicle performance at a high level even when the battery level is low. With the new models, stress-free operation hours for a battery charged have increased.
(The power keep function is available only when the operator selects P or S mode.) 7 7. Auto-off system If the operator leaves the vehicle with the key switch ON, the auto-off system forcibly shuts down the con- troller (equivalent to key switch OFF) after a preset period to prevent wasteful expenditure of energy. To re- start the vehicle, turn the key switch OFF and then ON. 8 9 8. Seat switch The seat switch does not allow the vehicle to travel as well as any material handling to operate by the mini- levers unless someone is on the operator's seat. 10 9. Anti-rollback function The anti-rollback function makes it easy to start the vehicle on an inclined surface.
This function is achieved by controlling both the drive motor and the brake system. 11 12 10. 2-speed travel speed control The 2-speed travel speed control switch sets a speed limit. The set value is adjustable by a switch on the multiple display. 13 11. Thermal Protector Overheat warning: Temperature in the controllers and motors are monitored by temperature sensors. If an abnormally high tem- perature is detected, the controller output is reduced to prevent overheating. The display will warn the oper- ator.
