Overview
Fan Status Monitor board enables independent, remote monitoring of up to two EC fans equipped with an ‘open collector type’ tachometer.
The fan fault signal is generated when the speed of any active fan, in two consecutive measurements, falls below the minimum or exceeds the maximum speed value. These minimum and maximum values are pre-set programmatically and saved to the non-volatile memory.
The general fault condition is indicated by the volt-free relay contacts and the fan alarm LED. In addition, the fan failure is indicated by the corresponding fan status LED indicator.
