A factory-shipped TRV200 should not be modified in
the field. It is specifically matched to the compressor.
Should replacing a VFD become necessary, only
parameter 4-18 Current Limit requires setting on the
VFD, refer to
Table 73, p. 133 . All other parameters
beside 4-18 Current Limit will be appropriately set in
field replacement VFDs. Do not use any other type or
brand of VFD when replacing the VFD.
N No otte e:: 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 parameter 4-18 in the Compressor
VFD:
1. Press Q Qu uiicckk M Me en nu u.
2. Press M My y P Pe errsso on na all M Me en nu u.
3. Navigate through the options using the U Up p and
D Do ow wn n arrows to find [4-18 Current Limit].
4. Adjust the current limit percentage value per unit
tonnage and voltage as shown in Table 73, p. 133 .
5. Press [OK].
