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 CX20x3 if:
- the fan cartridge has been in use for 5 years
- or the fan speed is less than 1000 rpm.
In a CX20x3 Embedded PC, the fan speed is controlled depending on the temperature.
Temperature | Fan control | Fan speed |
|---|---|---|
up to 40°C | 0% | 2400 rpm |
40°C … 85°C | 0% … 100%, controlled linearly | 2400 rpm…5900 rpm, controlled linearly |
above 85°C | 100% | 5900 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 Beckhoff Device Manager:https://infosys.beckhoff.com/content/1031/devicemanager/index.html?id=8733183011738041650
To replace the fan cartridge, follow these instructions:
- 1. Open the front flap using a screwdriver.
- 2. Pull the old fan cartridge out of the housing.
- 3. Push the new fan cartridge into the housing, leading with the contacts first. The guide rails on the fan match the guide rails in the housing.
- Close the front flap. When the fan starts again, this means you have successfully changed the fan cartridge.
