6. Additional Engine RPM Indicator (Tachometer) Connection: For this purpose, “W” signal of the cabin or chassis electrical connector can be used. The way of how to use the “W” signal is shown below. The maximum ampere in the W Terminal A = 0,5 A The average of the pulse onset voltage must be VMH =+30 V / VWL= -1 V The engine RPM value can be obtained by using the below formula, with the initial value of the alternator turning speed. The found value is modified according to the pulley diameter ratio of the alternator and the engine crankshaft. The below is the frequency of the fWW-Terminal in Hertz.

Below calculations to be used when an output is taken from the alternator D+ Terminal; Max sink current A = 0.3 A In 0.3 Ampere, maximum terminal current = 2.7 A Maksimum output voltage = 24 V 7. The usage of D+ signal: The usage of D+ Terminal is described below: The warning light and control unit is connected to the D+ terminal. If the regulator catches an error in the alternator (when the alternator is not working), the regulator decreases the potential of the D+ terminal to “LO Level” and then it results in turning the warning light on of the D+ terminal. While the alternator is working properly, the warning light keeps off. In this case, the regulator can feed an outsource power via this terminal.
