The training stand has been designed for performing measurement exercises and troubleshooting, as well as for learning how an alternator and pre-engaged starter motor work. The parts installed are printed in a list on the front panel and also carry the respective electrical switching symbol and circuit diagram. There are measuring points with 4 mm safety measuring sockets within the circuit diagram. The front panel can be written on using water-soluble pens.
The 3-phase alternator has been specially prepared and various faults can be activated via an integrated fault circuit to practice diagnostic methods and fault interpretation. Voltages, currents, control responses and redundancies can be measured, recorded and evaluated using a multimeter or oscilloscope via the measuring sockets in the front panel.
The 3-phase alternator is driven via a 230 V AC motor with frequency converter. In conjunction with a freely variable speed control and various switched consumers, this makes it possible to simulate all functions of the alternator and the charge controller. Real-world operating situations are thereby created and the kinds of measurements typically taken in practice can be performed. A digital display is fitted for this.
In addition to this, the stand is equipped with a vehicle battery and a starter. The starter is functional. It is equipped with a mechanical brake to simulate load conditions. An ammeter with current probe can be used to demonstrate the change in power consumption under load, as well as the battery discharge that this causes.
There is a selector switch between the circuit diagram of the pre-engaged starter motor and the 3-phase alternator. Depending on the position, it is possible to work either with the starter or with the alternator.
While work is being performed on the 3-phase alternator, the battery is charged, as it would be in real-world conditions. However, this obviously requires ALL fault switches and consumers to be switched off.
A special measuring instrument (battery tester) is provided for diagnosing the charge status of the battery.
No multimeter or oscilloscope is included in the scope of supply.
