Emerson E2 operation manual Copeland Discus with CoreSense Protection, Supported System Types

The meter is housed in a plastic enclosure suitable for installation on T35 DIN rail according to EN50022. The Energy Meter can be mounted with any orientation over the entire ambient temperature range, either on a DIN rail or in a panel. The meter is not sensitive to CT orientation to reduce installation errors.

6.3.5.2Supported System Types

The Energy Meter Series has a number of different possible system wiring configurations. To configure the meter, set the System Type via the User Interface or Mod- bus register 130 (if so equipped). The System Type tells the meter which of its current and voltage inputs are valid, which are to be ignored, and if neutral is connected. Set- ting the correct System Type prevents unwanted energy accumulation on unused inputs, selects the formula to cal- culate the Theoretical Maximum System Power, and deter- mines which phase loss algorithm is to be used. The phase loss algorithm is configured as a percent of the Line-to- Line System Voltage (except when in System Type 10) and also calculates the expected Line to Neutral voltages for system types that have Neutral (12 & 40).

For more information about this application, see the Energy Meter manual (P/N 026-1726).

6.3.6Modular Refrigerant Leak Detection Sensor (MRLDS)

Figure 6-6 - MRLDS

The Modular Refrigerant Leak Detection Sensor (MRLDS) continuously monitors for low levels of refrig- erants most commonly used in commercial refrigeration systems.

The MRLDS communicates with the E2 controller via MODBUS. The E2 will provides an interface while the MRLDS will provide the leak monitoring functionality.

6.3.7Copeland Discus with

CoreSense Protection

Figure 6-7- Copeland Discus Compressor

The Discus application can monitor semi-hermetic

compressors using the MODBUS network on E2 versions

3.01and above. The E2 monitors and records semi-her- metic compressor information. The Discus application has extensive logging capabilities that record a compressor’s Run History, Fault History, and Alarm Status.

The Copeland Discus is supported on E2 RX-300, CX- 400 and above.

6.3.8Copeland CoreSense Communications

Figure 6-8- Copeland CoreSense Communications

CoreSense Communications is used on A/C scroll compressors in the E2. The CoreSense Communications application provides the user interface requirements for configuration setup, status display, and alarm handling. CoreSense monitors information on the compressor's operation and sends it to the controller, and can also moni- tor conditions inside the compressor to prevent compres-
