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).
Fans
The temperature is sensed at several locations within the NCU.
If natural convection is not sufficient to ensure cooling of the NCU, the two fans in the dual fan
module are switched on automatically. The speed is controlled so that permissible temperature
limit values are maintained at the measuring points.
After switching the NCU on, the fan is activated for a brief period of time (function test) before
turning itself off again.
Note
The NCU can be operated only with an operational dual fan module.
