c. For Compressor Rated Load Amps, enter the
value noted as the Trane Motor Controller
nameplate's Output Current; refer to
and
Figure
90.
Notes:
•
The Compressor Rated Load Amps need to be
increased over the previously set RLA current as this
value now refers to the currents occurring between the
drive and the motor, which are slightly higher (at full
load rating point) than for a Wye Delta Starter Type.
•
The new Compressor Rated Load Amps are used to
"calibrate" the UC800 controller so it can provide a
current limit function at the correct current level. Motor
protection becomes a function of the AFD and its
settings.
•
Current flowing into the unit (into the drive) remains at
or below the previous RLA stamped on the original
shipped RTHD nameplate; thus, there is no need to
increase the upstream branch wiring or circuit
protection.
