CAUTION: IT IS STRONGLY RECOMMENDED TO CHECK ALL CONNECTIONS TO THE
CORELINK CONTROLLER PRIOR TO APPLYING POWER, ESPECIALLY POWER SUPPLY
VOLTAGE AND VOLTAGE ANALOG INPUTS LIKE THE EVAPORATOR PRESSURE TRANSDUCER
AND ELECTRONIC EXPANSION VALVE (OPTION). FAILURE TO DO SO CAN RESULT IN
ELECTRICAL DAMAGE TO THE CONTROLLER.
1. OVERVIEW & PREREQUISITES
The CoreLink Case Control System consists of Application Programming Modules (example: App Version
3.0.0 and 2.6.0) and physical Input/Output (“I/O”) that work together to control the various functions in
each case or walk in cooler/freezer. These programming modules control refrigeration, defrost,
evaporator fan, case lighting, and electronic expansion valves. The refrigeration system control network
includes the Emerson E2 RX controller and CoreLink controllers at each case and/or walk in
cooler/freezer. In the E2 programming, each CoreLink controller can be added via UltraSite or via the
front E2 panel. The E2 can then be used to monitor the status of each case alarm, scheduling, and any
other circuit level control value.
Compatibility between the E2 and the CoreLink controller can be verified based on the following:
CoreLink Application E2 Description Revision
Versions below 2.6.0 5270551 Revision 4
2.6.0 or above 5270551 Revision 5
The CoreLink application version is visible in the System Tab of the WebUI to confirm version
Note – All the screen shots in the document are captured using latest Revision of the description
file.
Hussmann reserves the right to change or revise specifications and Product design in connection
with any feature of our products. Such changes do not entitle the buyer to corresponding
changes, improvements, additions or replacement for equipment previously sold or shipped
The CoreLink case controllers are already preloaded with configurations and setting as per case
or walk-in product specifications. However installation guidelines of CoreLink can be downloaded
from https://www.hussmann.com/ns/Technical-Documents/0557046_A_Corelink_IO_EN.pdf

2. CoreLink – E2 Integration
This section details the integration between the Hussmann CoreLink case controller and the Emerson E2
controller. This includes power wiring, network wiring, software connections, E2 description files, and
E2 license keys.
2.1 Power Wiring
In most cases it is the responsibility of the Electrical Contractor (EC) to install the power wiring for the
cases and walk- ins as well as the Modbus and LAN communications cables. The Refrigeration
Contractor terminates the communication cabling. Figures (1.1) & (1.2) shows a reference wiring
diagram for Hussmann Insight cases. These diagrams are subject to change at any time without notice
due to continuous development. For changes and for other cases, please contact Hussmann
engineering.

2.2 Network Wiring
This section details the recommended communication wiring and termination for the CoreLink
controller and the E2.
NOTE: Figures (2.1) and (2.2) represent the connection of the Modbus communication
loop from CoreLink to the E2 communication port. It is recommended that this be left
disconnected until programming and controller addressing has been configured and
validated.
As per the site requirements, connect the max allowed CoreLink controller (Refer E2 manual for max
number of CoreLinks ) to E2 through Daisy chain connection as shown below

CAUTION: TO AVOID INCORRECT OR INVALID PARAMETERS BEING PASSED BETWEEN THE
E2 & THE CORELINK CASE CONTROLLERS, LEAVE THE MODBUS TERMINAL AT THE IN E2
RS485 COM2A (REF FIG(II)) UNPLUGGED UNTIL ALL THE PROGRAMMING IN THE E2 HAS
BEEN VERIFIED. FAILURE TO DO SO CAN RESULT IN ELECTRICAL DAMAGE TO THE
CONTROLLER.

The daisy chain connection of RS485 network needs to be terminated properly for
uninterrupted RS485 communication. Third-party devices which is integrated may or may
not have onboard termination jumpers — consult the manufacturer’s instructions for
termination information.
If an end device does not have termination jumpers, Emerson / CPC offers a termination
block that can be used to terminate MODBUS network endpoints (CPC P/N 535-2711).
Connect this block just before the end device Fig(iii)and connect the shield to earth
ground, keeping the exposed shield wire length as short as possible (3 inches ideal
maximum length). Alternatively, the last CoreLink in Network can be terminated by
connecting a RS485 termination resistor of Value 150Ω across CoreLink Pin 63, 64 .
2.3 CoreLink to E2 Via UltraSite
Install Ultrasite 5.07F02 or above. Login using the Emerson provided username and password
After connecting to the E2 via UltraSite, it may be necessary to create a Directory and add a Site
in UltraSite. Configure the Site as necessary. Now the E2 is connected to UltraSite
