Non-explosiv environment
General information: EC3-P32 is the superheat controller for systems with flammable refrigerants
(A2L/A3) and able to drive EMERSON Valves EX4-7-…FLR via M12 Connector ECV05A.
Warning:
• EC3-P32 has a potential ignition source and does not comply with ATEX
requirements. Installation only in non-explosive environment.
• EX4-7…FL R are currently released for R 290 in term of compat ibility. Th e
other listed refrigerants are subject to qualification at later stage. No warranty or product liability if EX4-7…FLR to be used with other refrigerants stored in software of EC3-P32.
Safety instructions:
• Read operatin g instru ctions th orough ly. Failu re to comp ly can result in device
failure, system damage or personal injury.
• According to EN 13313 it is intended for use by persons having the
appropriate knowledge and skill.
• Ensure that the system is correctly labeled with applied refrigerant type and
a warning for explosion ris k.
• Do not exceed the specified maximum ratings for temperature (max. +60°C),
voltage and current.
• Before installation or service disconnect all voltages from system and device.
• Do not operate system before all cable connections are completed.
• Entire electrical connections have to comp ly wit h local regulations. Note: The E C3-P32 seri es conta ins a VRLA battery = valve regulated rechargeable
lead-acid battery. T he batte ry m ust NO T be dis pose d of w ith othe r comm erci al was te.
Instead, it is the use r’s responsi bility to pass it to a desig na te d col l ec tion po int f or t he safe recycling of batteries (harmonized directive 2012/19/EU). For further information contac t your local environmental recycling center.
Mounting positio n:
The EC3-P32 is desig ned to be mounted onto a standard DIN rail. Mounting position: on vertical walls, with stepper motor connector on top side only.
Mounting of ECD-002:
• ECD-002 can be installed at any time also during operation.
71x29 mm cutout.
• Push controller in to panel cut-out.(1)
• Make sure that mounting lugs are flush with
outside of controller housing
• Insert Allen key into front panel holes and turn
clockwise. Mounti ng lugs will turn and grad ually move towards panel (2)
•
panel. Then move other mounting lug to the same position (3)
• Tighten both sides very carefully until keypad is
secured. Do not over ti ghten as mounting lugs
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 6.3 mm spade connector.
• Keep controller and sensor wiring well separated from mains wiring.
Minimum recommended distance 30 mm.
• Ensure that cables are not mounted near sharp edges.
• Use a class II category transformer for 24 VAC power supply. Do not ground the
24 VAC lines. We recommend using individual transformers for EC3 controller(s)
rd
and for 3
party contr ollers to avoi d pos sible in terferenc e or groun ding p roblems in the pow er suppl y. Connecting any EC3 inputs to mains voltage will permanently damage the EC3.
• The use of the relay is essential to protect the system in case of power failure if the
communications interface or the ECD-002 are not utilized.
• If the output relay is not utilized, the user must ensure appropriate safety pre-
cautions are in place to protect the system against damage caused by a power failure.
• In order to pro v ide system pro tection in the event of power loss, it is recommended
to change the battery annually.

Possibilities of connecting EC3-X32 to a network or PC:
• A TCP/IP Controller Readme file is available on the www.emersonclimate.eu
website to provide detailed information about TCP/IP Ethernet connectivity. Please refer to this file if you need information beyond the contents of this instruction sheet.
• Connect t he EC3 -P32 using the optional ECC-Nxx cable assembly or a standard
CAT5 netw or k cabl e w ith RJ4 5 plug s as se mbl y to a ne two rk o r ro ute r th at enables the controller to receive a dynamic TCP/IP address or
• Connect the EC3-P32 to a computer using a crossover cab le plu gged di rect ly into
the Ethernet port. In this case, the TCP/IP address of the computer must be manually modified to be compatible with the default address of the controller. Refer to the TCP/IP Controller-Readme file for more details.
Setting and visualizing Data: WebPages (recommended method)
• Make sure that digital input is 0 V (open), turn the power supply ON.
• Four parameters i.e. refrigerant ty pe (u0), pressure sensor type (uP), valve type (ut)
and control mode can be set only when digital input is open (0V) while the power supply is O N (24 V). This feature is for added safety to prevent accidental damage of compressors and other system components. All other parameters can be modified at any time.
• The EC3-P32 has a TCP/IP Ethernet communication interface enabling the
controller t o be di rec tly conn ect ed to a net work or a PC via th e stand ard Eth ern et port. The EC3-P32 controller has embedded WebPages to enable the user to visualize t he parameter lists using real text labels.
• To view W ebPages on the PC, a standard Web Browser like Internet Explorer ® 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-P32 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. R efer to the TCP/IP Controller-Readme file if a specific 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 file.
Installation in non explosive environment
• After a few moments, the default monitoring page should be displayed. If the
browser d oes no t open t he defa ult pa ge or displa y activ e data , the us er sho uld c heck the Internet browser “Option” configuration. Refer to th e TCP/IP Controller- Readme file.
• 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 initi al re quest to any of the o ther We bPage s. The factory defa ult settings are: Username: “EmersonID”, Password: “12”
• The default settings may be modified on the Display configuration page.
• Press the ta bs at the top of t he Mo nitor ing page with a le ft cl ick o f the mouse bu tton
to enter the respective Webpage.
• The paramet ers will b e visualized in real text together with the program code as
defined in the parameter list below.
• After the parameters have been modified, the complete list of settings can be saved
to the memory of the computer and used later to upload into another controll er. This can save a considerab le amount of ti me when using 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 temperature are available on a 15 minutes rolli ng chart. R efer to the TCP/IP C ontroller-Readme file for a com plete descrip tion of the feat ures availa ble for the TCP/ IP series of controllers.
