This version of the fan system controller has been designed to interface with an electric motor cooling system controller and outputs a protected low current DC proportional voltage that is scaled to represent the 0 to 100% fan speed demand.
The Controller uses the vehicle SAE J1939 temperature information to determine fan speed requirements while the standard and familiar HFS-J PC set-up graphical user interface allows the customer to set separate fan start, fan full on and alarm setpoints for each temperature zone being monitored. All other system features of the controller are available including a reverse output which can be interfaced via a relay to the E-motor controller or as required to change the direction of the motor drive signal.
The alarm output can be used to send the fan to full speed or connected to an annunciator to alert the vehicle operator to a cooling issue that needs attention.
