Using the Monitors - Speeds window

The Speeds tab displays the current speeds at the transmission input, transmission output, the turbine and the vehicle in real time.

Select Service > Monitor 1 > Speeds in the main window. If there is communication with a connected transmission control unit, the current speeds are displayed automatically in real time.

If communication with a transmission control unit is not possible, this will be indicated by a at the bottom right of the window:

This message is also displayed when communication with a connected transmission control unit has been interrupted.

For help in the event of communication problems, please refer to: Communication problems.

Once you have eliminated the communication problems, click "Yes" if ALADIN is to re-establish communication with a transmission control unit. An existing communication is shown by the progress bar.

The speeds are displayed with four dial instruments.

Signal Description

n1 Speeds at the transmission input in rotations per minute. The speed is also displayed as a digital value. If a fault is detected at this speed sensor, "Error" will be displayed as a digital value. Perform an upload for selective troubleshooting. For further information, please see: Upload.

n2 Speed at the transmission output in rotations per minute. The speed is also displayed as a digital value. If a fault is detected at this speed sensor, "Error" will be displayed as a digital value. Perform an upload for selective troubleshooting. For further information, please see: Upload.

n3 Speed at the turbine in rotations per minute. The speed is also displayed as a digital value. If a fault is detected at this speed sensor, "Error" will be displayed as a digital value. Perform an upload for selective troubleshooting. For further information, please see: Upload.

Vehicle Speed Vehicle speed in km/h. The speed is also displayed as a digital value in km/h. If a fault is detected at this speed sensor, "Error" will be displayed as a digital value. Perform an upload for selective troubleshooting. For further information, please see: Upload.

The general display is shown in every tab.

On top, there are four symbols for:

Symbol Description

General transmission fault.

General retarder fault.

Transmission temperature too high.

Retarder temperature too high.

Below, there is the real-time display of the following signals:

Signal Description

n1 Engine speed / transmission input speed

n2 Transmission output speed

n3 Turbine speed

FP Accelerator pedal position

BP Brake pedal position

Time Display of the sample time (for debugging tasks only)
