Launch of Copeland Discus with CoreSense™ Protection
Emerson Climate Technologies, Inc. is pleased to announce the release of CoreSense™
Protection for Copeland Discus compressors on 2D, 3D, 4D, and 6D platforms, starting February
2011. The CoreSense Protection module, shown in Figure 1, delivers a number of critical
compressor protection and diagnostics features for oil and motor protection. The module also
provides advanced capabilities such as modbus communication, diagnostics and verification for
enhanced compressor and system performance.
In addition, for customers who would like to have enhanced diagnostics, control, and protection
features with applied cost savings, Emerson offers Copeland Discus with CoreSense Diagnostics
(formerly known as Intelligent Store Discus). Refer to Marketing Bulletin MB2010CC-13 for further

Copeland Discus with
CoreSense Protection
Every Copeland Discus compressor will now feature CoreSense Protection as standard, installed
from the factory. A 3D Copeland Discus compressor with CoreSense Protection is shown in
Figure 2. The compressor asset information, such as the model number, serial number, and
compressor configuration, is loaded into the CoreSense Protection module for access through
open modbus communication protocol. The communication feature also provides compressor real
time run status and remote reset capability, which requires wiring one additional wire than the
conventional Sentronic oil protection module for continuous power supply to the module. Refer to
Application Engineering Bulletin AE-1367 for further product details on functionality and wiring
The CoreSense Protection module clearly indicates the status of the compressor in the form of
“Normal Operation”, “Warning”, “Trip” and “Lockout” conditions differentiated by color and flashing
LEDs. The color indicates the severity of the compressor status and the LED flash pattern
identifies the specific fault.
