9) DESCRIPTION, TESTING AND REPLACEMENT OF THE ELECTRONIC BOARDS, CURRENT CALIBRATION
The normal working conditions of the boards making up the generator are illustrated in the following sections and the standard values are
given for the electrical parameters found at the main points of the boards themselves.
All the measurements indicated can be made with a digital multimeter.
It should be remembered that the first test to be performed is a VISUAL CHECK !
The visual check reduces the fault-finding times and guides any subsequent action towards the damaged part !
In general, the points to be visually checked are:
- Input filter area.
- Electrolytic smoothing capacitors.
- Any traces of smoke found inside the casing.
- Power and signal connections.
- Overall state of the boards.
WARNING
When the machine is connected to the mains, the main circuit-breaker is live, independently of its position (open or closed) !
Therefore, it is advisable to pull out the power plug before touching anything inside the generator !
It is also necessary, because of the possible presence of capacitors charged to a high voltage, to wait for about one minute before
being able to work on the internal parts !
