Communication Capability
Instruction Sheet
PA-00368
June 2013
EC3-D72 is the superheat controller with TCP/IP connection for step-
per motor driven Electrical Control Valves EX4...EX6 and is optimized
to operate with the Copeland Digital Scroll series utilising a 0-10V input
from a third party controller. The controller synchronises the PWM digital
compressor solenoid valve with the superheat controlled by the electrical
control valve; EX series.
Note: This document contains short form instructions for
experienced users.
SAFETY INSTRUCTIONS
• Readinstallationinstructionsthoroughly.Failuretocomplycanresultin
device failure, system damage or personal injury.
• Theproductisintendedforusebypersonshavingtheappropriate
knowledge and skills.
• Disconnectallvoltagesfromsystembeforeinstallation.
• Donotoperatesystembeforeallcableconnectionsare completed .
• Complywithlocalelectricalregulationswhenwiring.
Note: The EC3-D72 series contains a lead, acid gel rechargeable bat-
tery. The battery must NOT be disposed of with other commercial waste.
Instead, it is the user’s responsibility to pass it to a designated collection
point for the safe recycling of batteries (harmonised directive 98/101/
EEC).Forfurtherinformationcontactyourlocalenvironmentalrecycling
center.

MOUNTING
• TheEC3-D72isdesignedtobemountedontoastandardDINrail.
ELECTRICAL INSTALLATION
• Refertotheelectricalwiringdiagramforelectricalconnections.
• Donotapplyvoltagetothecontrollerbeforecompletionofwiring.
• Groundthemetalhousingwitha¼”spadeconnector.
• Important: Keep controller and sensor wiring well separated from
mainswiring.Minimumrecommendeddistance1.2”.
WARNING: Use a class II category transformer for 24VAC power supply.
Do not ground the 24VAC lines. We recommend using individual trans-
formers for EC3 controller and for 3rd party controllers to avoid possible
interference or grounding problems in the power supply. Connecting any
EC3 inputs to mains voltage will permanently damage the EC3.

PREPARATION FOR START-UP
• Vacuumtheentirerefrigerationcircuit.
WARNING: Electrical Control Valves EX4...EX6 are delivered at half open
position. Do not charge system before closure of valve.
• Applysupplyvoltage24VtoEC3whilethecoolingdemanddigitalinput
is 0V (open). The valve will be driven to close position.
• Afterclosureofvalve,starttochargethesystemwithrefrigerant.
POSSIBILITIES OF CONNECTING EC3-D72 TO A NETWORK OR PC
ATCP/IPControllerReadmeleisavailableonthewww.emersonclimate.
eu website to provide detailed information about TCP/IP Ethernet connec-
tivity.Pleaserefertothisleifyouneedinformationbeyondthecontents
of this instruction sheet.
1) Connect the EC3-D72 using the optional ECC-N30 cable assembly or
astandardCAT5networkcablewithRJ45plugsassemblytoanetwork
or router that enables the controller to receive a dynamic TCP/IP ad-
dress or
2) Connect the EC3-D72 to a computer using a crossover cable plugged
directly into the Ethernet port. In this case, the TCP/IP address of the
computermustbemanuallymodiedtobecompatiblewiththedefault
addressofthecontroller.RefertotheTCP/IPController-Readmele
for more details.
SETTING AND VISUALIZING DATA: WEBPAGES (RECOMMENDED METHOD)
Important: Make sure that cooling demand input is 0V (open). Turn the
power supply ON.
Fourparametersi.e.refrigeranttype(u0),pressuresensortype(uP),
valve type (ut) and control mode can be set only when cooling demand
digital input is open (0V) and the power supply is ON (24V). This feature is
for added safety to prevent accidental damage of compressors and other
systemcomponents.Allotherparameterscanbemodiedatanytime.
The EC3-D72 has a TCP/IP Ethernet communication interface enabling
the controller to be directly connected to a network or a PC via the stan-
dard Ethernet port. The EC3-D72 controller has embedded WebPages to
enable the user to visualise the parameter lists using real text labels.
To view WebPages on the PC, a standard WebBrowser like Internet Ex-
plorer®orMozillaFirefoxandJREJavaRuntimeEnvironmentisneeded.
JREcanbedownloadedatnochargefromthewww.java.comwebsite.
Open the Internet browser program on the computer and, if EC3-D72 is
connected directly to PC with a crossover cable enter the default TCP/
IP address of the controller (192.168.1.101) into the address line, or the
dynamicaddressfromtheDHCPserverfromnetwork/Router.Refertothe
TCP/IPController-Readmeleifaspecicportisrequired.
It is possible to identify the dynamic TCP/IP address assigned by DHCP of
theRouterornetwork,refertotheTCP/IPController-Readmele.
After a few moments, the default monitoring page should be displayed.
If the browser does not open the default page or display active data, the
usershouldchecktheInternetbrowser“Option”conguration.Refertothe
TCP/IPController-Readmele.

The Monitoring and Alarm WebPages are read only and therefore it is not
necessary to enter a username or password. A username and password
willberequestedupontheinitialrequesttoanyoftheotherWebPages.
The factory default settings are :
Username: “EmersonID” , Password: “12”
ThedefaultsettingsmaybemodiedontheDisplaycongurationpage.
Press the tabs at the top of the Monitoring page with a left click of the
mouse button to enter the respective Webpage.
The parameters will be visualised in real text together with the program
codeasdenedintheparameterlistbelow.
Aftertheparametershavebeenmodied,thecompletelistofsettingscan
be saved to the memory of the computer and used later to upload into
another controller. This can save a considerable amount of time when us-
ing multiple controllers and over a period of time, a library can be created
containingtheparameterlistsforequipmentfordifferentapplications.
It is also possible to display live graphical data from the controller.
Superheat, evaporating pressure, coil-out temperature and evaporating
