Appendix A Acronyms/Terms
Table A-1 Acronyms/Terms
Acronym/Term
Definition
AC
Alternating Current
AFT
Ascending fault triggering
Alarms
Alarms indicate a condition at the limit of the normal operating envelope. Compressor alarms will still allow the Compressor to run,
but speed is reduced to bring the alarm condition under the alarm limit.
ASHRAE
American Society of Heating Refrigeration and Air-Conditioning Engineers (www.ashrae.org).
Backplane
A PCB for the purpose of power and control signal transmission. Many other components connect to this board.
BMCC
Bearing Motor Compressor Controller. The BMCC is the central processor board of the Compressor. Based on its sensor inputs, it
controls the bearing and motor system and maintains Compressor control within the operating limits.
Cavity Sensor
NTC temperature sensor located behind the Backplane for the purpose of sensing motor-cooling vapor temperature. Provides
overheat protection to motor windings.
CE
CE marking ensures the free movement within the European market of products that conform to the requirements of EU legislation
(e.g., safety, health and environmental protection and is a key indicator of a product’s compliance with legislation.
The CE marking is affixed by manufacturers to their products. By placing CE marking on a product, manufacturers
declare on their sole responsibility that the products comply with all the legal requirements in force in Europe.

CIM / I/O-
board
Compressor Interface Module; the part of the compressor electronics where the user connects all field connection wiring such as RS-
485, EXV, and analog / digital wiring. Also known as the I/O board.
