OUT output will immediately turn OFF.
5.31.6 Product Probe Support
The XM Circuit application supports a product probe
temperature input for each case controller associated. To
enable support for product temperature inputs, set the “En
Product Prob” parameter to Yes.
If one or more product probe inputs are used, high and
low temperature alarming may be enabled.
5.32 XR75CX Case Display
The XR75CX-Case Display is a microprocessor based
controller, suitable for applications on medium or low
temperature ventilated refrigeration units. It has up to four
(4) analog inputs: discharge air temperature, product
temperature, defrost temperature and coil out temperature,
four (4) relay outputs, and up to two (2) digital inputs.
5.33 Condenser
An air-cooled condenser consists of one or more fans
that blow air across a manifold of tubing to cool heated
refrigerant and condense it into a liquid. In an evaporative
condenser, water is sprayed across a condenser coil, which
cools the refrigerant as water is evaporated. Control of the
evaporative condenser is similar in ways to the air cooled
strategy in that the Condenser Control application uses
PID control to activate or deactivate fans (thus increasing
or decreasing the amount of evaporative cooling).
5.34 XJ Condensing Unit
The XJ Condensing Unit is a device for controlling the
XJ Condensing Unit, also known as the XJ Scroll Unit.
Site Supervisor will perform tasks for coordination, log-
ging, alarming, and access for configuration and status.
The XJ Scroll Unit follows the typical MODBUS commis-
sioning method. In the XJ Scroll Unit, the device address
is determined using dip switches on the device itself. The
range of allowable addresses is 1 through 255.
Copeland Scroll™ outdoor condensing units provide
scroll compressor technology with advanced diagnostic
controls to ensure reliable performance and operation in
food service applications. Protection and diagnostic fea-
tures are controlled by an electronic integrated control
board. This control board provides base control functions
related to temperature controller, defrost, evaporator fan
control, compressor protection (for example, current over-
load, phase reversal, liquid/vapor injection control, self
diagnostics and warnings). These error codes can be seen
by an LED display for troubleshooting and maintenance.
Medium and low temperature units are available in single
and three phase 208/230 volts. The -002 and -012 BOM
product is approved for operation in ambients from120°F
to -10°F. For more information, refer to the Copeland
Scroll™ Outdoor Condensing Unit literature P/N AE5-
1377 R3.
