Danfoss Turbocor Twin-Turbine TTS Series User Manual

Chapter 6.0 Electrical Specifications
6.1 Supply Voltage and Frequency
Turbocor compressors are designed to operate with a power supply that is within an acceptable
tolerance for each nominally rated voltage and frequency. The tables below specify the acceptable
supply voltage and frequency ranges. Using a supply voltage/frequency at or beyond the range limit
will cause the compressor to shut down.
Table 6-1 Acceptable AC Voltage Range
• • • CAUTION • • •
Application of a compressor to any voltage which is outside of the nominal rated voltage defined on the compressor nameplate
will result in voiding of the compressor warranty from Danfoss LLC, unless otherwise stated by Danfoss LLC. This includes any
application of a 400V compressor in a 380V application without the use of a transformer to correct the voltage going into the
compressor.
NOTE
Refer to the TTS/TGS Compressor Nomenclature section of this manual for details on the compressor voltage availability.
Table 6-2 Acceptable Frequency Range
6.2 Compressor Current Limit and Operating Range Settings
The new compressor controller (version 3.0.0 and above; see Section "1.1 Scope" on page 11) is
designed to allow a user to configure the current setting based on the intended application. The
compressor defines the Full Load Amperage (FLA) and Locked Rotor Amperage (LRA) as a range on the
nameplate. The settings for the FLA and LRA are adjustable using the Service Monitoring Tool (SMT) or
directly from the customer controller application.
The 3-Phase Over Current Alarm (FLA) cannot be set higher than the 3-Phase Over-Current Fault limit
(LRA). The maximum fault limit and alarm limit settings are dependent upon the Voltage and Model.
The Model type defines the range for the FLA and LRA values.
Nominal Voltage Acceptable Voltage Range
380V 342 - 418 VAC
400V 360 - 440 VAC
