The information in this article applies to standard Bigfoot and Bigfoot XL vehicles – model numbers B5-440-36, B5-440-48, B5-540-48XL and BF-030-48. Note that vehicle customization may cause variation from the information in this article.
Shown below is a Bigfoot XL Taylor-Dunn utility vehicle.
1. Start Switch: The start switch turns on the vehicle electrical control system. This switch may or may not require a key to operate.
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.
Note: All electrical devices including lights, horn, etc. will not function unless the switch is ON.
2. Directional Control Switch: This switch determines the direction of travel. Your vehicle will have one of two types of switches, depending on when it was manufactured.
The rocker switch shown in the dash illustration above has three positions:
- FORWARD: Push the top of the switch all the way in to travel forward.
- REVERSE: Push the bottom of the switch all the way in to travel in reverse.
- OFF: The center position between forward and reverse is the “direction” OFF position.
The OFF position does NOT turn the vehicle control system OFF. Use the start switch to turn the vehicle control system OFF. Refer to start switch entry in this section for details regarding turning the vehicle control system off.
3. Hi-Low Speed Switch: Push the bottom of the High/Low switch (turtle) for slow vehicle speed. Push the top of the switch (rabbit) for normal speed.
4. USB Port: This port allows the vehicle operator to charge devices (for example, a smart phone or tablet). The dual-port design is capable of charging two devices at the same time. Note that the port is only active when the start switch is ON.
5. Dash Display: The Smart View Display (SVD) Indicator is shown below. Depending on your vehicle’s specifications, one of two available dash displays will be installed in this location.
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 BSI will only reset to full after a full charging cycle has completed. In addition, the BSI will not reset to full unless the battery is discharged below 75 percent before starting the charge cycle.
Hour Meter: The hour meter has three functions: Key Hours, Run Time Hours and Pump Hours. One of these three functions will be displayed whenever either of the Hours Indicators are visible at the right side of the display.
Key Hours: This icon represents the silhouette of a key and indicates the accumulated length of time in hours that the key switch is in the ON position. When the display is turned on, the Key Hours will be displayed for approximately 5 seconds as indicated by the Key Hours Indicator located at the lower left of the display.
Pump Hours: This icon represents a motor symbol with a “P” in the center and indicates the accumulated length of time the hydraulic pump has been in operation. This is an optional feature. After Key Hours, the Pump Hours will be displayed for approximately 5 seconds as indicated by the Pump Hours Indicator located at the lower left of the display.
Run Time Hours: This icon represents a motor symbol with a “T” in the center and indicates 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. After the Pump Hours, the Run Time Hours will be displayed as indicated by the Run Time Hours Indicator located at the left of the display.
System Fault Monitor: The display will indicate a fault code whenever the control system logic detects a problem with the control system. A fault code is 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 or read Taylor-Dunn Fault Codes for descriptions of the fault codes.
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 a 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, 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. Read Taylor-Dunn Fault Codes for more information.
Refer to your Vehicle Operator and Service Manual for more information.
