"Type" – displays the code of the voltage regulator type operating under the "LIN" protocol: A1,
A2, A3, A4, B1, B2, B3, B4, C3, D1, D2, E1.
"Excitation" – the value of the excitation winding current of the alternator. Measured in
percentage. Read from the voltage regulator via the LIN protocol.
"Errors" – indicator of errors transmitted by the regulator to the engine control unit. The following
errors are possible:
• E – electrical malfunction;
• M – mechanical malfunction;
• T (thermal) – overheating.
"Temp. °С" – the voltage regulator's own temperature measured by it.
On the diagnostics screen of IStars 12V type alternators (see Figure 25), information similar to
COM type alternators is displayed, as well as the following parameters inherent to this type of
alternators:
"Speed RPM" - alternator revolutions measured by the voltage regulator.
"Voltage" – stabilization voltage measured by the voltage regulator.
The "Starter" button performs alternator testing in starter mode.
