Replace the fan cartridge
 | Service life The fan cartridge must be replaced every 5 years. Spare fan cartridges can be ordered from Beckhoff Service. |
Replace the fan cartridge of the CX20x2 if:
- the fan cartridge has been used for 5 years
- or the fan speed is less than 1000 rpm.
In a CX20x2 Embedded PC the fan speed is controlled depending on the temperature.
Temperature | Fan control | Fan speed |
|---|---|---|
up to 30 °C | 30 % | 3400 rpm |
30 °C … 75 °C | 30 % … 100 %, linear control | 3400 rpm ... 6000 rpm, linear regulated |
above 75 °C | 100 % | 6000 rpm |
Use the IPC diagnostics and monitor the fan speed to determine a fan fault.
Access to the fan status is described in the documentation for the IPC diagnostics:

- 2. Pull the old fan cartridge from the housing.

The guide rails at the fan match the guide rails in the housing.
