List Manual (LH21), 05/2016
Description:
Sets the run-on time for the device fan.
After a pulse inhibit (operating state >= 0.9 is reached) the device fan(s) run until the following conditions are
satisfied:
- the power unit has cooled down.
- the run-on time has expired (p55450).
The power unit is considered to have cooled down if all of the power unit temperature sensors indicate values of less
than 35 °C.
Description:
Setting to test the device fan.
Value:
0:
Fan off
1:
Fan on
Note:
If p55455 = 0:
--> the internal control is active.
If p55455 = 1:
--> the device fan is switched on for testing.
--> the internal control is not active.
Description:
Sets the minimum speed for the device fan.
For instance, this parameter is used to test the maximum fan noise.
Dependency:
Refer to: p55457
Note:
For setting p55456 = 100 %, the automatic adaptation of the fan speed to the power unit temperature is deactivated.
This parameter is only active for device types with variable-speed fans.
30 kW device:
- the fans are not variable-speed fans.
- parameter p55456 is inactive.
120 kW device:
- the fans are variable-speed fans.
- parameter p55456 is active.
Description:
Sets the maximum speed for the device fan.
This parameter is used for the following applications:
- reducing fan noise in the final test area.
- consciously allowing the device temperature to rise faster to stress the device for testing purposes.
