Installation and Startup

Most of the drive parameters are already set up when the drive
is shipped except for a short list of unit specific parameters
obtained from the unit and motor nameplates that need to be
field programmed.

Refer to Table 17 for a list of items that are programmed in the
drive at the factory for use with Trane chillers. In the event that
the drive needs to be reset, these parameters need to be
reprogrammed into the drive.
To reset the drive to the Danfoss defaults, perform the following
procedure.
1. Disconnect power to the drive, and wait for the display to
shut down.
2. While powering up the drive, press and hold the following
keys: Status, Main, and OK.
3. After 5 seconds, release the keys.

Important: These parameters are supposed to have been
set at the factory to the Trane-specific values
shown here in
actual drive start up that this is so and correct
any one of the parameter settings as
necessary.
