5.13 XR75CX Case Display
The XR75CX-Case Display is a microprocessor based
controller, suitable for applications on medium or low
temperature ventilated refrigeration units. The Site
Supervisor will communicate with the XR75CX Case
Display via MODBUS using the Open MODBUS
infrastructure.
How To Add an XR75CX CaseDsp Device on the
Site Supervisor:
1. From Home screen, navigate to Main Menu>
Summaries and Floor Plans> Site Summaries>
Refrigeration, click the screen drop-down arrow
on the upper right of the screen, click Add
Controls.
2. Select the Control or Application Type -
XR75CX CaseDsp, enter the Quantity, Control
Name and Serial Type. Note that Serial Type
information can be enter later. Click Save to add
the application.
3. A Confirmation box will appear saying that the
application is successfully added to the system,
click Close or Edit these controls.
4. The system will display the new application(s) on
the Site Summary screen.
5. Click the XR75CX CaseDsp application panel
box to view the application.
6. The system will display the XR75CX CaseDsp
application parameters.
7. The user can view and configure the properties of
the application by setting the Edit Mode to “ON”
on the screen drop-down arrow on the upper right

5.13.1 Overview
Site Supervisor will provide an interface to the
XR75CX CD and alarming. The XR75CX CD can be
networked with Site Supervisor to share sensor data with a
Standard Circuit application that controls the case
refrigeration, and it has four on-board relays that can be
used as satellite outputs by the other Site Supervisor
applications.

NOTE: When an XR75CX-CD is associated
with a Standard Circuit application in Site
Supervisor, a Case Temp Hi Limit Exceeded or
Case Temp Lo Limit Exceeded alarm that
occurs for the XR75CX-CD’s associated case will cause
the main module and remote display’s Alarm LED to
turn ON, indicating an active alarm. Unlike XR75CX-
CD’s temperature sensor alarms, a “No Alarm”
message is shown on the display if a case temperature
alarm occurs.
