U of O Campus Zero Waste Program
Tiger Electric Truck

OPERATION MANUAL
(Items listed here are in addition to operation of regular gas vehicles)

The information contained herein is a condensation of more complete information contained in the Tiger Electric Truck Owner’s/Operator’s Manual, copies of which are kept at the Recycling Quonset, the Recycling Trailer, and the F.S. Mobile Equipment Shop. See the manual for further info as needed.

The Tiger Electric Truck

The Tiger Electric Truck is a certified low-speed vehicle. It meets federal and state requirements for operation on public thoroughfares with posted speeds not in excess of 35 miles per hour (the posted speed must be 35 mph or less). So in addition to use on the U of O campus, the Tiger can legally be operated on public streets (but subject to the Franklin Blvd. restriction noted below).

Driving the Tiger is largely the same as driving a modern gas-powered vehicle. All operating controls, lights, signals, accessories, and other devices are similar (see below about the heater operation). Familiarize yourself with the location and operation of these controls and accessories before driving. The Tiger also has an automatic transmission and excellent acceleration.

NOTE: The Tiger is never to be driven down Franklin Blvd. (although crossing Franklin is allowed and necessary). Operator training will include a discussion of alternate Campus routes.

Operating the Tiger

Prior to using the Tiger, perform a pre-operational inspection according to the pre-op checklist located in the vehicle. Of particular importance is checking the battery pack charge level (see below for more information). Alert a supervisor to any problems, concerns, or fault codes noted during the inspection before operating the vehicle.

Operating the Tiger is simple:

Some additional basics about operating the Tiger:

Battery Pack Charge Level, Read-outs, & Fault Codes

(see graphic below for LED display examples)

The battery pack charge level is indicated by 10 vertical “bars” displayed on the LED screen below a charge level “bracket” graphic on the display body. Each bar represents an increment of charge, and together they indicate the level of charge from fully charged to fully discharged. A solid bar indicates an increment of “charge” – a hollow bar indicates an increment of “discharge.”

Next to the battery charge indicator is another “bracket” graphic with an exclamation point “!.” This is where fault codes display should operational problems warrant them.

Beneath the battery charge indicator are the operating hour codes. When the vehicle starts, the display will cycle through each of three codes, showing the hours for each code and a small “egg timer” symbol. The first two of these will display momentarily only (and can be ignored), while the third will remain displayed during operation:

The three graphics below show the LED display with the unit in three states of charge/discharge. All examples show the unit with 27.5 key-switch hours of usage and no fault codes:

Fully Charged
Half Charged
Nearly Discharged

Fault Codes

The Tiger Electric Truck Servon electronic controller is capable of alerting the operator to various operational problems through the display of numerous "Fault Codes.” Most of these codes will require reference to the full Owner’s/Operator’s Manual or a diagnosis by the Mobile Equipment Shop. Should one of these fault codes appear, the operator must check with a supervisor before operating the vehicle. All fault codes appear under the “exclamation point” shown above.

The Sequence Fault Code

The only “routine” fault code is the Sequence Fault, which appears as “Seq. Fault.” The controller prevents the Tiger from being started unless the transmission shifter is in the “Neutral” position. The “Seq.” Fault” code indicates that the vehicle was in gear when started. The vehicle must be turned off, shifted into neutral, and re-started.

Once any fault code has been diagnosed and the problem fixed, the fault code will be cleared by re-initiating the starting sequence (such as with the “Seq. Fault” code).

Charging

The Tiger has an onboard 120-volt charger that charges from any standard (household current) electrical outlet. Allowing for various factors like speed, load weight, frequency of stopping, etc., the Tiger can travel between 25 and 65 miles on a single charge (we should expect something in the neighborhood of 35 to 50 miles for our usage). However, the controller LED display will always be the most accurate indication of the battery pack charge level.

Rather than charge the battery pack based upon the charge level shown on the LED display, we will charge the vehicle after each use or day of use (which ever is greater).

To charge the battery pack, find the black, male plug for the onboard charger. It’s located outside the vehicle beneath where the bed and cab meet just behind the passenger seat. Plug this into the female end of a standard, grounded extension cord, and then plug the extension cord into the ground-fault circuit interrupter (GFCI). Plug the GFCI into any standard electrical outlet. Finally, press the "Reset" button on the GFCI to activate it.

Even from a completely discharged state, the Tiger’s battery pack will fully charge in 6 to 8 hours. With daily charging, our Tiger should only require a couple of hours to charge.

The vehicle can be charged while inside or outside. The use of the GFCI ensures safe charging even if the Tiger is outside, in the rain, etc..

***CAUTION*** – Charging must never take place while the Tiger is “On” – even momentarily. Always turn the vehicle completely off before connecting the charger; and always disconnect the charger before turning the vehicle on (unplugging the GFCI or extension cord disconnects the charger). Even turning the vehicle on briefly to check the charge level can damage the Sevcon controller. To check the charge level, disconnect the charger, and then turn the vehicle on to check the level of charge.

Current Routes for Tiger Truck

After checking out the vehicle with the checklist, please service & tally GMP at
25 Campus PDO’s (Public Drop-Off)  <service paper too, as needed>
Campus & Grounds
L.E.R.C. / R.O.T.C
Agate Hall & House
OP Barn  <service paper, too!>
YWCA
1761 & 1791 Alder
Trailers A, C & D
Clinical Services
Music
The Daily Grind
Lillis Cafe
Fortis Construction Trailer  <service paper, too!>


Service paper, too, as noted.  Make sure to lock up if you leave the vehicle unattended.  At end of route, plug the Tiger in to re-charge (then hit reset on GFCI).  Wash out rubbermaid bins as needed.

 

The Tiger Truck route is currently evolving and adding more sites.
It has been especially handy and efficient for:
set-up, servicing, and break down at events
servicing campus wide PDO’s (each year has seen a few more PDO’s added at various locations, with more to come...)
assisting with overflowing dorm operations during move-outs
construction sensitive locations
