Start-up with medium voltage stator 65
Start-up of the air damper
If the converter is NOT equipped with an air damper, continue to the next section.
A motor-controlled air damper is optionally available for cold conditions where humidity, cold air and dust
could penetrate into the converter as backflow through the air outlet channel. The air damper is a plate
located at the air outlet channel where it can close the air outlet mechanically. The air damper function
closes the damper when the converter is not operating and its temperature goes below a predefined limit.
The function opens the damper again when the converter restarts and its temperature rises high enough.

Verify that FF005 is open.
Check wiring.
Close the damper (T100 power off) and connect the auxiliary
voltages.
• Check that A42: UAO2 = 0 V.
Set temporarily parameter 15.06 ANALOGUE OUTPUT 2 setting 112
to 1910.
15.06 ANALOGUE
OUTPUT 2
Short-circuit temporarily K3 34-31 to get 230 V to T100.
Check that operation of the damper follows the graph shown below by writing values to parameter
1910 (this parameter imitates PP TEMP values):
• 1910< 18 damper closed
• 1910 > 18 damper starts to open, see the graph
• 1910 = 50 damper fully open, plate in 90° position.
Remove temporary short-circuit in K3 34-31. The damper closes by
means of a spring in about 15 s.
