eFlex™ Compressor VFD Programming
Parameters
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 Table
74, p. 131 . 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 74, p. 131 .
5. Press [OK].
Note: Parameter '4-18 Current Limit' for field installed
TRV200 drives must be set according to table
below for proper operation and to meet overload
protection requirements. Replacement drive will
not run the compressor until set properly. Factory
installed drives are programmed properly for unit
operation. Parameter 4-18 is available via the
quick menu.

Fall Restraint
WARNING
Falling Off Equipment!
Failure to follow instructions below could result in
death or serious injury.
This unit is built with fall restraint slots located on
unit top that MUST be used during servicing. These
slots are to be used with fall restraint equipment that
will not allow an individual to reach the unit edge.
However such equipment will NOT prevent falling to
the ground, as they are NOT designed to withstand
the force of a falling individual.
The fall restraint is located approximately 3 feet from the
unit edge.
