Page 200 Parts and Service Manual - eTT8/eTT12/eTT16 - Troubleshooting OPT10 Diagnostic Usage The OPT10 digital display is capable of displaying many tractor inputs and outputs. These are extremely helpful when trying to diagnose an issue with the tractor. This section will explain how to use the OPT10 to examine this diagnostic data.
Page 201: Error Code Troubleshooting
Parts and Service Manual - eTT8/eTT12/eTT16 - Troubleshooting Error Code Troubleshooting Should the eTT tractor encounter a system error, the OPT10 display may display one or more error codes. These codes are intended to direct technicians to the most likely cause of the error. Making use of both the error codes as well as the diagnostic abilities of the OPT10 greatly facilitate troubleshooting.
Page 202 Parts and Service Manual - eTT8/eTT12/eTT16 - Troubleshooting Error Code Troubleshooting 15: WARN. TRACTION TEMPERATURE SENSOR The eTT traction motor features a built-in thermal sensor.  Verify resistance of the thermal sensor on the motor (2-pin connector mounted to the traction motor).
Page 203 Parts and Service Manual - eTT8/eTT12/eTT16 - Troubleshooting Error Code Troubleshooting 23: ERR. TRACTION HIGH VOLTAGE This error happens when the regenerative braking system is unable to put excess energy back into the battery.  If the battery is fully charged the braking energy has nowhere to go. Modify the driving and charging procedures to prevent extensive downhill usage with a completely full battery.
Page 204 Parts and Service Manual - eTT8/eTT12/eTT16 - Troubleshooting Error Code Troubleshooting 41: HIGH HYDRAULIC FLUID TEMPERATURE The normally open hydraulic temperature switch input has closed indicating the hydraulic fluid has exceeded 160°F/71°C. Test the temperature of the hydraulic fluid in the hydraulic tank. If the fluid in the hydraulic tank exceeds 140°F take the tractor out of service to prevent component damage and check the following.
Page 205 Parts and Service Manual - eTT8/eTT12/eTT16 - Troubleshooting Error Code Troubleshooting 44: SHIFTING FAULT The shifting has timed-out. This happens when the tractor attempts to shift gears and the gear detection switches don’t confirm that the shift has completed. Use the OPT10 to verify that the inputs LOW SHIFT SWITCH and HIGH SHIFT SWITCH match the physical positioning of the shift switch (when the switch is in tow, the LOW SHIFT SWITCH input should be 1).

Page 216: Hydraulic System Overview
Parts and Service Manual - eTT8/eTT12/eTT16 - Logic, Controls, and 4WS System Hydraulic System Overview The eTT tractor hydraulic system works as an on-demand system. The purpose is to limit the amount of time the hydraulic pump is in operation. This reduces battery load and extends time between charges. This is accomplished through a combination of hydraulic components that store and monitor hydraulic pressure.
Page 217 Parts and Service Manual - eTT8/eTT12/eTT16 - Logic, Controls, and 4WS System Hydraulic System Overview Hydraulic Pump The hydraulic pump pulls fluid from the reservoir and pressurizes it to charge the system accumulator. The pump is a hydraulic gear pump mounted to an AC induction motor. The speed of the motor is controlled by the VMC30 controller based on logic inputs to the system.

Page 222 Parts and Service Manual - eTT8/eTT12/eTT16 - Logic, Controls, and 4WS System Steering System Overview The eTT tractor features a computer controlled four wheel steering system. The system operates in a slave/master configuration treating the front axle as the master and the rear axle as the slave. The process proceeds as follows: ...
Page 223 Parts and Service Manual - eTT8/eTT12/eTT16 - Logic, Controls, and 4WS System Steering Calibration Procedure The eTT tractor steering has been calibrated at the factory to ensure that the front and rear steering coordinate properly. Should an axle be serviced or a steering sensor be serviced, it may be necessary to re-calibrate the four wheel steering system.
Page 224 Parts and Service Manual - eTT8/eTT12/eTT16 - Logic, Controls, and 4WS System Regenerative Braking Tuning Instructions The eTT tractor features regenerative braking. This feature converts tractor motion to electrical energy which is then used to put a small amount of charge back into the battery. The regenerative braking slows the tractor at a rate proportional to the amount of electrical energy removed.

Parts and Service Manual - eTT8/eTT12/eTT16 - Battery Care Battery Basics Eagle Tugs is not a battery nor charger manufacturer, but Eagle may recommend certain brands and models. The below information applies regardless of what brand and model traction battery or charger is on the truck. Battery Basics The eTT traction battery is a heavy duty industrial battery designed specifically for electrical vehicle usage.
Page 229: Charger Basics
Parts and Service Manual - eTT8/eTT12/eTT16 - Battery Care Charger Basics Charger Basics The purpose of the charger is to use electrical power to reverse the chemical reaction in the battery and return it to a charged state. During the charge process the lead plates in the battery reverse their chemical change and the electrolyte acid becomes more concentrated.
Page 230: Battery Care
Parts and Service Manual - eTT8/eTT12/eTT16 - Battery Care Battery Care The flooded lead acid batteries used in the eTT series tractors are not maintenance free. The battery must be regularly maintained to ensure safe operation and battery longevity. Battery Watering Flooded lead acid batteries lose water during charging and regular usage.
Page 231: Cold Weather Battery Usage
Parts and Service Manual - eTT8/eTT12/eTT16 - Battery Care Cold Weather Battery Usage There are two issues that batteries face in extremely cold weather; Reduced Capacity and Freezing Electrolyte. Reduced Capacity As the battery temperature drops, the internal resistance of the battery increases and the usable capacity is decreased.

Page 233 Parts and Service Manual - eTT8/eTT12/eTT16 - Battery Care Cold Weather Battery Usage (Continued) Electrolyte Freezing The electrolyte in the eTT traction battery is a weak sulfuric acid solution. As the battery is discharged, the acid is absorbed by the battery plates and the electrolyte becomes weaker turning into mostly water. A deeply discharged battery will readily freeze in cold weather.
