5. Hi-Low Speed Switch: Push the top of the switch (rabbit) for normal speed, push the bottom of the switch (turtle) for slow speed.
6. Smart View Display: The Smart View Display (SVD) functions as a Battery Status Indicator (BSI), hour meter (HM), speed controller status monitor and as an optional maintenance monitor feature. The operation of each of these functions is described below.
Battery Status Indicator: A bar graph representing the current state of charge is located across the top of the display.
When the batteries are fully charged, all segments of the bar graph will be on. As the batteries are used, segments will turn off from right to left.
When the batteries are discharged to 75 percent (25 percent battery remaining), the last three segments will flash indicating that you are approaching the end of the battery cycle. At this time, the vehicle’s batteries should be charged as soon as possible.
At 90 percent (10 percent battery remaining), all segments will flash and the vehicle's speed will be reduced. At this time, the vehicle should be removed from service for charging. Discharging beyond 90 percent will result in damage to the batteries that will shorten the battery life span.
Note: The battery status gauge as well as any faults indicating low battery voltage will not reset until the batteries have successfully completed a charging cycle.
Hour Meter: Depending on the revision level of the controller, there are one or two hour meter functions – Key Hours and Run Time Hours.
Run Time Hours is the accumulated length of time that the vehicle has been in operation. Time is accumulated when the FS-1 switch in the accelerator module is closed. The Run Time Hours will be displayed as indicated by the Run Time Hours Indicator located at the left of the display. The icon represents a motor symbol with a “T” in the center.
System Fault Monitor: The display will indicate a fault code whenever the control system detects a problem with the control system. A fault code is being displayed whenever the Fault Code Indicator (the letter "F") is visible at the left of the numeric display.
Maintenance Monitor: The Maintenance Monitor function is optional. The Maintenance Monitor function can be turned on or off by your dealer. Contact your Taylor-Dunn Dealer to enable or disable this feature.
Operation: The SVD notifies the operator 10 hours (standard) before scheduled maintenance is due. During this warning period, the meter will continue to alert the operator. This should allow sufficient time for the operator to schedule the maintenance that is due with minimal downtime. If the scheduled maintenance is not performed before the warning period elapses, then the vehicle's maximum speed will be significantly reduced.
Warning Period: The warning starts when the Maintenance Indicator is ON and the Wrench icon is flashing. The Wrench icon will continue to flash until the warning time has expired.
Maintenance Due: Once the warning has expired and the maintenance is due, the Wrench icon will stop flashing and remain ON. Additionally, the vehicle's maximum speed will be significantly reduced until the maintenance is performed and the display is reset. The display should only be reset by an authorized technician. Refer to the illustrated parts section of the Vehicle Operator and Service Manual for information regarding tools required to reset the Smart View Display.
Speed Controller Status: The display will indicate a fault code whenever the control system logic detects a problem with the control system. A fault code is being displayed whenever the Fault Code Indicator (the letter "F") is visible at the left of the numeric display. Refer to the fault code table in your Vehicle Operator and Service Manual for a full description of the fault codes.
7. Horn Switch: Depress the switch to sound the horn.
8. Start Switch: The switch turns on the vehicle electrical control system. Rotate the switch clockwise to turn the vehicle system ON and counterclockwise to turn the vehicle system OFF.
The switch should be in the OFF position whenever the operator leaves the driver’s seat. This switch is designed to secure and disable the vehicle. The key can only be removed when the switch is in the OFF position.
9. Emergency Stop Switch: The emergency stop switch will immediately and abruptly stop the vehicle.
Caution: Unless in an emergency, do not activate the emergency stop switch while the vehicle is in motion. This vehicle is equipped with an automatic electric parking brake. Activating the emergency stop switch will immediately apply the brake and abruptly stop the vehicle. This may result in injury to the occupants and/or upsetting the load being carried or towed.
1. Turn Signal Switch: The turn signal switch lever is located on the left side of the steering column. The switch is not self canceling. You must return the switch to the center OFF position after the turn is completed.
Push FORWARD to activate the right turn signal.
Pull BACK to activate the left turn signal.
2. Hazard Light Switch: The hazard light switch is located on the turn signal switch. The switch is a small tab or knob under the turn signal lever.
To activate the hazard lights, PULL the tab out. To turn the hazard lights off, PUSH the turn signal lever forward or back.
3. Steering: The steering wheel and steering system are like an automobile. To turn right, turn the steering wheel clockwise. To turn left, turn the steering wheel counterclockwise.
4. Foot Brake Pedal: The foot brake pedal is located to the left of the throttle pedal. This pedal is designed for operation with the driver’s right foot. It works like the brake in an automobile. Applying pressure to the brake pedal slows the vehicle according to the amount of pressure applied. Relieving pressure from the pedal releases the braking action.
5. Throttle Pedal: The throttle pedal is located to the right of the brake pedal. It controls the speed of the vehicle and operates like the throttle pedal in an automobile.
Depress the pedal to increase speed and release the pedal to decrease speed.
Parking Brake, Automatic
This vehicle may be equipped with an optional automatically actuated electromagnetic parking brake. During normal operation, the parking brake will be applied when the throttle pedal is released and the motor comes to a stop. The brake will release again when the throttle pedal is depressed. Unless in an emergency, do not turn the start switch OFF while the vehicle is in motion. Turning the start switch OFF will immediately apply the parking brake, stopping the vehicle and resulting in accelerated wear of the brake. Some motor control system faults will result in parking brake application or failure of the brake to release. Should this occur, there is a brake bypass switch that will release the brake and allow the vehicle to be moved. For more information, refer to Towing This Vehicle section in your Vehicle Operator and Service Manual. The brake bypass switch will not function if the batteries are disconnected or there is a failure in the vehicle power supply. Should this occur and the vehicle must be moved, the drive wheels must be placed on a towing dolly or the brake removed from the motor.
Seat Interlock Switch
A switch located under the driver’s seat disables the power to the vehicle when the driver leaves the seat.
The driver must be seated for the vehicle to operate. Whenever the driver leaves the vehicle, the driver should turn the key-switch off, place the forward-off-reverse switch in the center OFF position and set the park brake.
Warning: The seat interlock switch is only one part of the vehicle safety system. The interlock switch should not be relied upon as the only safety feature used to disable or disengage this vehicle. Doing so could result in unexpected movement of the vehicle, causing severe bodily injury and/or property damage.
The parking brake is actuated with a hand lever, which is located to the right of the driver. To set the parking brake, push down on the brake pedal and pull the lever up until it locks. To release the park brake, depress the foot brake pedal, pull up on the park brake handle, push the release button and lower the handle.
