Fan Motor Pressure and Fan rpm
The motor intergrates a proportional pressure relief valve,
the fan speed (and thus the cooling performance) can be
infinitely controlled depending on two different simultaneous
input signals from temperature sensors.
The cooling fan controller processes the two input signals
and controls the valve coil current. The proportional relief
valve has a fail safe characteristic, this means, max. relief
valve setting is adjusted automatically if the voltage supply
is interrupted (e.g. broken wire). This results in a max. fan
speed and therefore in a max. cooling performance.
