Dual fan module
Functions of the dual fan module
The dual fan module cools the CPU with two redundant fans.
The temperature inside the NCU and the correct functioning of the fan are monitored. Fan
faults are displayed and can be read out by means of the diagnostic buffer.
• Fan alarm ⇒ alarm 2110 "NCK temperature alarm": If one of the two fans no longer rotates
or the speed is out of tolerance.
• Fan fault ⇒ alarm 2120 "NCK fan alarm type %1": When none of the fans turn.
If the software does not respond within approx. 1 minute, the components are shut down
automatically.
You can find more information on the alarms in the Diagnostics Manual.
Additional information on the diagnostics buffer can be found in the Basic Functions
Function Manual, see PLC signal LBP_NC.E_ATempAlarm (fan temperature alarm).
