Hydraulic Fan System Controller : HFS - 2
Software Setup Guide:
1
Click the ‘down arrow ‘ and select from the menu for
‘Proportional or ON/OFF’ type output current. In ON/OFF mode, no
Min, Max, Test or Rev Vlv current settings are available and the
output will be dependent on the supply voltage to the controller.
In ON/OFF mode the ramps are left active to aide the use of a ‘soft-
shift’ valve if used.

Use the up/down arrows on each box or directly enter a value (
in seconds ) in the range 0 – 60S for the ramp UP and DOWN.

Set the Maximum valve current here from 0 – 100%.
Maximum current ( 100% ) depends on coil Ohmic value
and supply voltage and will determine the fans maximum
speed.

controller to automatically try an error reset every 4 seconds to
see if the fault has cleared.
