Overview
Multi-Zone Fan Status Monitor board enables independent, remote monitoring of up to five EC fans, connected either in
Standard (common speed control signal for each fan) or
Multi-Zone (independent speed control signal for each fan) configuration and 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.
