BEFORE YOU BEGIN
Read these instructions completely and carefully.
AVISO
PERSONAL PROTECTION EQUIPMENT (PPE)
Personal Protection Equipment (PPE) is required whenever servicing refrigeration equipment.
Always wear safety glasses, gloves, protective boots or shoes, long pants, and a long-sleeve
shirt when working with this equipment.
AVISO
Electrostatic discharge (ESD) is the sudden
ow of electricity between two electrically
charged objects caused by contact, an
electrical short, or dielectric breakdown.
Hussmann recommends industry workers
use antistatic wrist straps, ESD wrist strap, or
ground bracelet when working on electronic
devices which can be damaged by ESD.
Please consult chosen strap literature for best
practices for usage.
This warning does not mean that Hussmann products
will cause cancer or reproductive harm, or is in
violation of any product-safety standards or
requirements. As clarified by the California State
government, Proposition 65 can be considered more of
a‘right to know’ law than a pure product safetylaw.
When used as designed, Hussmann believes that our
products are notharmful. We provide the Proposition
65 warning to stay in compliance with California State
law. It is your responsibility to provide accurate
Proposition 65 warning labels to your customers when
necessary. For more information on Proposition 65,
please visit the California State government website.

CONTROLLER OVERVIEW
CoreLink is a control system for complete management of HE H-Series condensing units with
options of controlling various compressor types and dierent types of condensers. One of the
main features of this solution is continuous modulation control of the main equipment such as
a compressor and condenser contributing to the energy eciency and reliability of the entire
system. When the controller is turned ON, it will perform a quick check-up on all inputs/outs
congurations to ensure all sensors are performing optimally.
Any alarm generated during the quick check-up will be displayed on the seven-segment
display as “err”. The control board is designed for DIN rail assembly. CoreLink can manage both
medium and low temperature applications. This system has a with Web UI built interface and
seven-segment display modules for the user interface.
➢ Main Features:
• Management of dierent type of compressors

Make sure the condensing unit is switched o
before working on electrical connections. All
operations must be carried out by qualied
personnel. To ensure proper connections,
comply with the following:
DO NOT work around live electrical equipment.
All operations and installations should be
carried out by qualied personnel only. For
safety purposes, always make sure the
device is switched OFF before touching
connections.
All system components should be obtained
from Hussmann to ensure system
compatibility and reliability.
Under no circumstances is the device to be
opened – Opening the case on the device will
void the warranty.
Prevent the device from being dropped,
knocked or shaken as this can cause
irreparable damage.
The device must always be inserted inside
an electrical panel that can be accessed by
authorized personnel only.
Comply with the temperature and humidity
limits specied in the manual. Prevent
frequent and sudden changes in temperature
and/or humidity.
Do not mount devices in extremely damp
and/or dirt-laden areas; Electronics should
never come in contact with water or any
other type of liquid.
Separate the cables of the analog inputs from
those of the digital inputs and the serial line
cables from the power cables (resistive as well
as inductive) in order to prevent malfunction
due to electromagnetic interference.
Make connections as short as possible, and do
not wind them around electrically connected
parts.
Do not install device in area of high mechanical
stress vibrations. Harsh vibrations can
cause component level failure or unintended
disconnection of controller cables.
Do not clean the device with corrosive
chemical products, solvents or aggressive
detergents. The device must not be used in
applications that dier from that specied in
the following material.
Do not install the device in the presence of
ammable or explosive gas. Device is not
ignition protected for application in ammable
environments.
Do not expose device to sulfur and ammonia
gas, smoke and salt spray that can cause
corrosion and/or oxidation.
Do not install device near items that generate
large amounts of magnetic interference, or
abnormal operation can result.
Always make sure the area near the cooling
slot is ventilated and that the controllers
always receive sucient passage for cooling
air.
Always comply with the laws and regulations
applicable in the country where the device
is installed. Always protect and stow the
device securely so it can only be accessed
by authorized personnel. If controller
malfunctions, always contact the relative
distributor for the device to be repaired.

Be aware of the current limits for the power
output devices. Additional power outputs are
available on the CoreLink case controller and
valve drivers.
Please pay extra attention to the current limits
when applying power accessories. Avoid
overloading the devices.
Hussmann is not responsible for misuse of
device. Hussmann is not held responsible for
deviation from this manual and its intended
use. If you have any questions, please contact
your local Hussmann branch.
When utilizing the digital inputs of the CoreLink
Case Controller, use another transformer
in order to prevent the digital inputs from
malfunctioning or being damaged.
WARNING!
DO NOT use the same secondary of the
controller’s power. Doing so can result in
damage to case controller.
Any inputs that are powered with a voltage that
diers from that supplied by the device (+12V
or +5V) must be powered separately with
another transformer.
DO NOT exceed the maximum current capacity
of the onboard controller relays.
Always verify the capacity of the output used.
DO NOT use dierent voltages for the various
groups of relays nor within each group.
Digital Output (RELAYS) have two separate
groups with separate commons. Please refer
to the wiring diagrams on the Web UI or within
this manual for more details.
Electrical devices that are controlled by the
analog outputs must be powered separately
with another transformer (Do not use the same
secondary of the controller’s power).
DO NOT plug in accessory devices that are not
approved by Hussmann.
USB WARNINGS!
USB port can support maximum 200mA.
DO NOT plug your smart device or tablet into
the USB port of the controller. You cannot
charge your personal devices from this port.
The CoreLink Case Controller can be connected
to a computer via an external USB to
Ethernet adapter. This adapter is not set up for
xed or continuous connection. If the adapter
should be kept connected continuously, the
room temperature must not exceed 50°C or
122°F.

Superheat
If suction line temperature is only a few degrees above saturation on the suction line temperature
outlet, superheat is too low and could be dangerous for compressor operation. If suction line
temperature rises drastically above the saturation temperature on the suction line, superheat is
too high for normal refrigeration performance.

Discharge Pressure Protection
• Discharge Pressure Low Alarm: Alarm is active when actual discharge pressure value is
lower than the DPP low pressure limit for a duration set in DPP pressure alarm delay.
• Discharge Pressure High Alarm: Alarm is active when actual discharge pressure value
is greater than the DPP high pressure limit for a duration set in DPP Pressure Alarm Delay.
• Compressor Shutdown Limit: Compressor will shutdown and generate alarm when
actual discharge pressure reaches to Compressor Shutdown limit for a duration set in
DPP pressure alarm delay. Alarm is clear when discharge pressure is less than DPP High
Pressure Limit - DPP high pressure di after DPP pressure alarm delay.
Suction Pressure Protection
The controller is equipped with the ability to generate an alarm or shut down the compressor in
the event of low suction pressure.
• Suction Low Pressure Alarm: Alarm is generated when actual suction pressure value is
less than the suction pressure low limit for the duration set in SPP pressure alarm delay.
• Suction High Pressure Alarm: Alarm is generated when actual suction pressure value is
greater than the SPP High pressure limit for the duration set in the SPP pressure alarm delay.
• Suction Low Pressure Shutdown Alarm: Compressor will shutdown and generate
alarm when suction pressure reaches to SPP compressor shutdown limit after SPP pressure
alarm delay. Alarm is clear when suction pressure is greater than suction shutdown limit +
SPP Low Pressure Di after SPP pressure alarm delay.
