SPEED SENSOR STATIC STANDALONE TEST
In order to be able to sense the currents, a series resistor of e.g. 200 Ohm must be used. This resistor is integrated in the con-
troller.
When the sensor is tested separately, resistor must be integrated in sensor connector as per below schematic.
The idea is to connect the sensor to an external power source and measure the DC voltage across the series resistor.
The voltage reading should be either 1.2V (from the 7mA ± 1mA current level) or 2.6 –3.0V (for the 14mA ± 1mA current level).
By slowly moving gear teeth or a metal part in front of the sensor (1.8 mm max. distance), toggling between the two levels should
be noticed.
