Introduction to the Handbook This handbook provides the information for the operation, adjustment and maintenance of your Standen T2 / T3 CAN-Bus electrical control system. To enable you to achieve the best results from the machine, the manufacturer recommends that you read the handbook thoroughly prior to using the machine for the first time.
INSTALLATION CAN-Bus Control System Installation The harvester CAN-Bus control system requires a 12 Volt negative earth power supply fed directly from the tractor battery using the 50Amp power lead supplied. Red cable to positive (+) and black cable to negative (-). Ensure the polarity of the battery connections are made correctly to prevent damage to the system components.
OPERATION Starting the Control System Set the rocker switch (item 1, fig 6) to the ON position. The START screen (see fig 7) will display after approximately 45 seconds. Press and hold the green start button (item 2, fig 6) for 3 seconds. The MAIN screen will display (see fig 8).
OPERATION Emergency Stop Buttons An emergency stop button is present on all screens and mechanical stop buttons (item 1, fig 9) are mounted at the rear of the harvester. When any of the buttons are activated, all harvester functions are stopped. Screen STOP buttons When a screen stop button is pressed, all harvester functions stop and the terminal reverts to the ‘START’...
Press the (ESC) button once (item 1, fig 10). The MACHINE CONFIGURATION screen will display (see fig 11). Press the button to select your machine type (T2 or T3). Select the 1 separator unit fitted to your machine. Omega scrolls...

OPERATION 1.20 Automatic roller table reverse pressure During harvesting it may be necessary to change the pressure at which the rollers reverse. The automatic reverse sequence is triggered by a pressure transducer that senses the operating pressure within the system. Increase or decrease the reverse pressure in small steps until the required operation is achieved.

1.25 OPERATION Headland START and STOP sequences A headland start sequence and stop sequence can be recorded into the system to automatically start/stop the elements and lift the digger out of work. To program the START sequence In the START options area: Press the start RECORD button In real time, select the elements in the order you want them to start.
1.26 ESC (x1) Machine Configuration Screen Pressing the ESC button once displays the machine configuration screen. This screen covers machine type (T2 or T3), 1 & 2 separator type and icon selection for optional equipment. These settings must be configured to your machine for the screens to display and function correctly.

1.27 OPERATION Main Page Master ON The elements in this area can be selected to start simultaneously. Pressing the ‘MAIN ELEMENTS ON’ button on the main screen (<< ) will start the selected elements. Discharge/Spreader Icon Configuration The elevator ON/OFF icon can be configured to one of these settings: Setting (1): Switches the elevator ON/OFF only.
1.29 OPERATION Slave Box Functions Along with the touch-screen terminal, all commonly used controls are repeated on the slave box. Slave box switch functions are: Item 1 - Touch-screen terminal ON/OFF. Item 2 - Start switch for machine control module. Item 3 - Headland program start/stop sequence.
OPERATION 1.30 LH joystick functions LH joystick default functions are drawbar steer and axle steer. LH joystick secondary functions are 1 separator clod roller height and 1 separator angle. To activate the secondary functions, press and hold the button (item 11, fig 37). Re-centre the joystick before releasing the button.

If a red LED is illuminated there is a system fault. Press the stop button on any screen and restart the system by pressing and holding the slave box start button for at least 3 seconds. If the problem persists contact your Standen dealer. Item 1 = Constant green LED.
MAINTENANCE 1.42 System Fuses The power lead attached to the tractor is permanently live. The feed to the slave box and service terminal is protected by the 2Amp fuse (item 1, fig 51) inside the slave box. The main distribution box (item 6, fig 48) contains the following fuses: 25Amp fuses to protect the module power feeds (item 1, fig 52).
