Input/Output Board facilitating a connection between the compressor controller and/ or
PC and the compressor. It allows the user to control the compressor and allows the
compressor to return status and sensor information to the user. Also known as the CIM.
The Inverter converts the DC bus voltage into an adjustable frequency and adjustable
amplitude, three-phase simulated AC voltage.
Kilopascal.
Kilopascal Gauge.
Kilowatt.
Kilovolt.
Load Balance Valve. A modulating valve that can be installed to bypass discharge gas to
the inlet of the evaporator to provide gas flow at certain conditions such as startup,
surge, and further unloading of the compressor.
Light-Emitting Diode.
The elevation or suspension of the compressor shaft by the magnetic field created by the
magnetic bearings.
A transformer-like device designed to introduce a specific amount of inductive reactance
into a circuit. When this occurs, it limits the change in current in the line, which in turn
filters the waveform and attenuates electrical noise and harmonics associated with an
inverter/drive output.
Limited Liability Company.
Locked Rotor Ampere.
Low voltage directive.
A serial communications protocol published by Modicon in 1979 for use with its
programmable logic controllers (PLCs). It has become a de facto standard
communications protocol in industry, and is now the most commonly available means of
connecting industrial electronic devices. Modbus allows for communication between
many devices connected to the same network, for example a system that measures
temperature and humidity and communicates the results to a computer.
A software program provided by Danfoss LLC that can be downloaded to a PC or laptop
computer to monitor, regulate, control or verify the operation of a compressor.
