The EC3-332 is a dedicated controller for refrigerated coldrooms with superheat control and a driver for an Alco Controls Electrical Control Valve EX4...EX8. In addition the EC3-332 controls air temperature and manages defrost and fan(s).

Humidity 0…80% r.h. non condensing

Protection class IP20

Pressure transmitter input 24VDC, 4...20mA

4-20 mA Analog output For connection to any 3 rd party controller with

12/24VDC power supply and appropriate burden.

Deviation from input signal ±8% max

Digital Inputs 24VAC/DC

Output relays (4) Inductive (AC15) 250V/2A

Alarm, Comp SPDT contacts, AgNi, resistive (AC1) 250V/8A

Heater, Fan SPST contacts, AgNi, resistive (AC1) 250V/6A

A PT4 pressure transmitter (4) and an ECN-Pxx pipe temperature sensor (1) measure saturated suction gas pressure and suction gas temperature at the evaporator outlet and feed the signals into the superheat control loop. The superheat controller output modulates the opening of the EX4…EX8 Electrical

Control Valve (11) thus optimising the refrigerant mass flow through the evaporator. The ECN-Sxx air temperature sensor (2) measures air-in temperature at the evaporator and feeds a signal into the air temperature thermostat. The ECN-Fxx fin sensor (3) is used for defrost termination. Digital input (5) should be connected to the serial control loop of a compressor (where applicable) and digital input (6) should be connected to the coldroom door contact. The controller has 4 relay outputs to control the compressor (7), defrost heater (8) evaporator fan (10) and an external alarm device (9). Please consult the technical data (right) for input and output ratings.

The EC3-332 features an integral backup battery to close the electrical control valve in case of power loss. Due to the positive shut-off characteristics of the

EX4…EX8 Electrical Control Valves, a liquid line solenoid valve is not needed to prevent flooding of the compressor.

The optional ECD-001 Display Unit (13) can be connected to the EC3-332 for local display of control parameters and for controller setup without the use of a PC.

Because the EC3-332 is fully functional without display unit the ECD-001 may be removed at any time.

Mounting

The EC3-332 is designed to be mounted onto a standard DIN rail. Mounting position: on vertical walls, with stepper motor connector on top side only.

The ECD-001 can be mounted in panels with a 71 x 29 mm cutout. See dimensional drawing below for space requirements including rear connectors.

Push controller into panel cutout (1).

Make sure that mounting lugs are flush with outside of controller housing

Insert Allen key into front panel holes and turn clockwise. Mounting lugs will turn and gradually move towards panel (2)

Turn Allen key until mounting lug barely touches panel. Then move other mounting lug to the same position (3)

Tighten both sides very carefully until controller is secured. Do not over tighten as mounting lugs will break easily.

Operating Instructions

Electrical Installation

Refer to the electrical wiring diagram (below) for electrical connections. A copy of this diagram is labeled on the controller. Use connection wires/cables suitable for

90°C operation (EN 60730-1). Ground the metal housing with a 6.3mm spade connector.

EC3 analog inputs are for dedicated sensors only and should not be connected to any other devices. Digital inputs should only be connected to 24VAC/DC.

Connecting any EC3 inputs to mains voltage will permanently damage the EC3.

Important: Keep controller and sensor wiring well separated from mains wiring.

Minimum recommended distance 30mm..

Warning: Use a class II category transformer for 24VAC power supply

(EN 61558). Do not ground the 24VAC lines. We recommend to use one transformer per EC3 controller and to use separate transformers for 3 rd 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.

Recommended Sensor Positions for Cold Room Applications

(see diagram on page 1)

ECN-Pxx coil-out temperature sensor (1): Position directly after the evaporator on the common suction line as shown below. Insure proper thermal contact by using a metallic pipe clamp or temperature resistant plastic straps. Do not use standard plastic tie wraps (as used for electrical wiring) as they may become loose over time, which could result in faulty temperature measurements and poor superheat control performance. It is recommended to insulate the coil-out temperature sensor with ARMAFLEX™ or equivalent. The recommended position of the pipe sensors is between 9 and 3 o'clock as shown in the picture.

PT4-07M suction pressure transmitter (4): Position on the common suction line close to coil-out temperature sensor (1)

ECN-Sxx air temperature sensor (2): Should be mounted on spacers in the middle of the air duct so that there is airflow around and positioned on the inlet of the evaporator as high as possible close to the ceiling.

ECN-Fxx fin temperature sensor (3): Position on the evaporator, asymmetric closer to the expansion valve.

Setup and Parameter Modification Using the Display Unit

ECD-001

For convenience, an infrared receiver for the optional IR remote control unit is build-in, enabling quick and easy modification of the system parameters when a computer interface is not available.

• 4: Set the electronic control valve to 100% open

• 5: Displays the current TCP/IP address

• 6: Set the controller's TCP/IP address to 192.168.1.101 (default value). This change is only temporary. A power down will reset the previous address.

• 7: Resets all parameters to the factory default setting. The controller will indicate “oF” during the reset and the valve will close.

Display of Data:

The data to be permanently shown on the display can be selected by the user

(parameter /1). In case of an alarm, the alarm code is displayed alternately with the selected data. The user can inhibit the alarm code.

It is possible to temporarily display these values. This is a useful feature when initially setting-up the system without the aid of the WebPages. Press the SEL button to scroll through all possible displayable data. The display will show for one second the numerical identifier of the data (see /1 parameter) and then the selected data. After two minutes the display will return to the by parameter /1 selected data.

This action is only valid when parameter H2 = 3.

Visualising Data: WebPages

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.

The EC3-332 has a TCP/IP Ethernet communication interface enabling the controller to be directly connected to a PC or network via the standard Ethernet port. The EC3-332 controller has embedded WebPages to enable the user to easily visualise the parameter lists using real text labels.

No special software or hardware is required.

Connect the EC3-332 using the optional ECX-N60 cable assembly to a network or hub that enables the controller to receive a dynamic TCP/IP address. If a DHCP server is not available, the controller can be connected 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 modified to be compatible with the default address of the controller. Refer to the TCP/IP Controller-Readme file for more details.

Open the Internet browser program on the computer and enter the default TCP/IP address of the controller into the address line of the Internet browser: 192.168.1.101 or the dynamic address from the DHCP server. Refer to the TCP/IP Controller-

Readme file if a specific port is required.

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” configuration. Refer to the TCP/IP Controller-

Readme file.
