Checking the Function of the Fans

You can check the function of the fans by setting a parameter.
The basic procedure for changing operating parameters is described in the manual of the inverter
or the communication product (see the operating manual of the inverter or communication product).
Procedure:
1. Select the parameter Fan test or FanTst and set to On.
2. Save settings.
3. Check whether air is being drawn in through the bottom and is coming out of the upper
ventilation grids and whether the fans are making any unusual noises.
If no air is being drawn in through the bottom, no air is coming out of the ventilation grids, or
the fans are making unusual noises, then the fans were presumably installed improperly.
Check whether the fans have been installed correctly.
If the fans were installed correctly, contact Service (see Section 15, page 46).
4. Select the parameter Fan test or FanTst and set to Off.
5. Save settings.
