3.2 Fan Control Modul (FCM)

The Fan Control Module, based on a microcontroller, monitors up

to 4 DC fans rotation speed depending on the temperature.

Up to 4 temperature sensors (NTC) can be connected.

It controls the theoretical speed value of each fan.

If the fan speed falls below the theoretical value or by cable

damage or by temperature sensor cable short-circuit, an alarm is

generated and the fans rotate at their maximum speed.

The FCM has a CMM connection (I2C-bus) for remote alarm

signal and for individual configuration of the FCMs.
