A factory-shipped TRV200 should not be modified in
the field. It is specifically matched to the compressor.
Should replacing a VFD become necessary, refer to . All
other parameters will be appropriately set in field
replacement VFDs. Do not use any other type or brand
of VFD when replacing the VFD.
NNoottee:: Failure to set parameter 4-18 Current Limit on a
field replacement VFD will not allow the
compressor to start and result in A18 Start Failed
or A49 Speed Limit on the VFD.
To verify and/or set parameters in the Compressor
VFD:
1. Press QQuuiicckk MMeennuu.
2. Press MMyy PPeerrssoonnaall MMeennuu.
3. Navigate through the options using the UUpp and
DDoowwnn arrows to parameter.
4. Adjust the value as shown in .
5. Press [OK].
