THE OUTPUT OF 3RD WIRE SIGNAL
A. FREQUENCY GENERATOR FUNCTION (FG TYPE FOR SPEED SENSOR SIGNAL)
B. ROTATION DETECTOR FUNCTION (RD TYPE FOR ROTOR LOCKED ALARM SIGNAL)
C. SPECIAL FUNCTION
TEMPERATURE CONTROL
WHEN THE APPLICATION ENVIRONMENT OF COOLING FAN IS RATHER SENSITIVE TO THE NOISE, IT NEEDS A FAN ENABLES AIRFLOW TO CHANGE WITH THE ACTUAL OPERATION TEMPERATURE OF THE SYSTEM, THAT UNDER THE PRE REQUISITON OF SYSTEM HEAT DISSIPATING TEMPERATURE (SO IS THE AIRFLOW) AND THE NOISE LEVEL WILL DROP COMPARATIVELY. WHEN THE ACTUAL OPERATING TEMERATURE IS RISEN, THE RPM OF COOLING FAN WILL INCREASE AND INCREASE THE AIRFLOW AND TO ACHIEVE TOTAL HEAT DISSIPATION.
