Description: Displays the power unit fan operating hours.
The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has been replaced).
Dependency: Refer to: p0252
Description: Sets the maximum operating time of the power unit fan.
The pre-alarm (warning) is output 500 hours before this set value.
The monitoring is de-activated with p0252 = 0.
Dependency: Refer to: p0251
Note: For chassis units, the maximum operating duration in the power unit parameter is set to 50000 via the factory set-
ting.
Description: Sets starting time 1 to monitor the cooling system after power on command.
After powering-up, the following signals must be present within starting time 1:
- "RKA powered-up"
- "RKA liquid flow OK"
When a fault occurs, an appropriate message is output.
Dependency: Refer to: F49152, F49153
