WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by
Trane or others, refer to the appropriate
manufacturer’s literature for allowable waiting periods
for discharge of capacitors. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged.
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.
Note: 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 Quick Menu.
2. Press My Personal Menu.
3. Navigate through the options using the Up and Down
arrows to parameter.
4. Adjust the value as shown in Table 80, p. 184 and
Table 81, p. 184.
5. Press [OK].
