Calibration Initial Truesight Setup ® The first time that Truesight is powered up, it will ask a series of questions. Choose the appropriate choice or follow the instruction given. 1. The initial startup screen is: TRUESIGHT V1.00R • Press enter V1.00B 2.
Accessing Calibration From Menus Truesight will automatically access calibrations after completion of initial setup is complete. 1. Push escape from run screen Main>Calibrate 2. Turn scroll knob to Main>>Calibrate • Press enter 3. Turn scroll knob to Calibrate>>desired calibration Cal>Center Bump •...
Auto Deadzone Calibration The Auto Dead Zone calibration allows Truesight to automatically detect the minium voltage outputs that will cause the valve or motor to turn the wheels. 1. To calibrate go to >>Calibration>>Auto Detect DZ Cal>Auto Detect DZ • Park in a generally level area 2.
Auto Engage Sensor Calibration The Auto-Engage sensor calibration learns a feederhouse position at which to engage Truesight. When the header passes below the chosen height, Truesight will delay a short time and then begin steering. (see Auto-Engage Delay in the Settings section of this manual) 1.
Settings Properly setting the Truesight™ system is essential to having responsive row guidance control. You should become very familiar with the steps in this section. Access Settings 1. Push escape from run screen. Main>Setup 2. Turn scroll knob to Main>>Setup. •...
1. To change this setting go to >>Setup>>Range in menu. Setup>Range = 40 • Press enter 2. Turn scroll knob to “desired value”. • Press enter 3. Push escape till returned to run screen. Tilt range (Default = 20) The Tilt Range setting allows Truesight to automatically ‘bump’ the combine up a slope to compensate for the natural tendency of the combine to slide down.
Auxiliary Engage The Auxiliary Engage setting allows the auxiliary (foot) switch type to be chosen. If you choose to use the Headsight provided footswitch – choose “Default”. If you do not wish to use any auxiliary switch – choose “Off”.
Alert Timer The Alert Timer allows the operator to have an audible alert sound at a preset time after the engagement of Truesight. The setting ranges from off to 20 minutes in 30 second intervals. 1. To change this setting go to >>Setup>>Alert Timer in menu. Setup>Alert Timer •...
Deadband (Default = 8) The Deadband setting adjusts the maximum swing of the crop sensor before Truesight issues a steer command. Decrease the Deadband if: • The system wanders in the row without even trying to turn the wheels. Increase the Deadband if: •...
Auto-Engage Delay (Default = 2.5 sec) The Auto-Engage Delay adjusts the time delay between when the operator lowers the header and Truesight engages when using the Auto-Engage feature. The delay period starts when the feederhouse lowers below the setpoint chosen in the Auto-Engage calibration. The delay allows the operator a few seconds to manually guide the machine to the beginning of the row at the headland.
Speed Select (Default = GPS) Speed Select is a Safety Feature of Truesight, disable at your own risk! The Speed Select setting properly configures Truesight to read the speed sensor. If the Speed Select is set to “OFF”, the minimum and maximum speed limits to engage Truesight will be disabled. If you wish to allow the min and max speed limits, choose the option that best matches your combine.
Fine Control (Default = 0) The Fine Control setting is a control used on systems with fast hydraulics to help smooth out the transition when it tries to just start to turn the wheels. This setting is normally unnecessary for systems with steering motors and AccuGuide valves, but a value of 30-40 is recommend for aftermarket steering valve systems.
Operation Requirements for Operation Turn off TrueSight 2 Remote before entering roadway! Five requirements must be met before the Truesight 2 system will engage: 1. Seat switch safety must have contact • Operator must be sitting in seat to engage system 2.
Overview Truesight Navigation ® How to Navigate There are four controls on the Truesight remote: 1. Steering Wheel Button • Tapping this button engages/disengages Truesight • Holding this button for more than 3 seconds enables/disables the Auto-Engage feature 2. Red X (Escape Command) •...
