Trane RT-SVX10C-EN 사용자 설명서

Units shipped with an optional variable frequency drive
(VFD) are preset and run tested at the factory.  If a problem
with a VFD occurs, ensure that the programmed param-
eters listed in Table 5-8 have been set before replacing the
drive.

Should replacing the a VFD become necessary, the re-
placement is not configured with all of Trane's operating
parameters.  The VFD must be programmed before at-
tempting to operate the unit.

To verify and/or program a VFD, use the following steps:

1. At the unit, turn the 115 volt control circuit switch 1S70 to
the "Off" position.

2. Turn the 24 volt control circuit switch to the "Off' position.

* These parameters are motor specific and the actual motor nameplate rating must be used. Do not use the unit name

plate values.
