The

EC3

33x

Series form a new generation of electronic

controllers for refrigeration and air conditioning.

The controllers feature a DIN rail mounted housing and a

separate optional display unit in the small industry standard

housing form factor. They off

er maximum functionality such as

superheat, temperature and defrost controller with built-

TCP/IP Ethernet

communications and WebServer

functionality. Any standard WebBrowser (e.g. Internet

Explorer

or Mozilla Firefox) can be used for monitoring or

parameter setting.

The version with Echelon LON

network interface is for use in

more complex systems, where different controllers must

communicate with each other.

Features

• Superheat control with self-adapting algorithm and driver

circuit for stepper motor driven Electrical Control Valves

EX4 … EX8

• Air temperature control

• Defrost and fan management

• Limitation of evaporating pressure (MOP)

• Feed-through of 4 … 20mA signal of evaporating pressure

transmitter to analogue output to operate multiple

controllers with a common pressure transmitter

• 2 digital inputs for compressor safety loop and coldroom

door contact

• 4 relay outputs for compressor, fan, defrost and alarm

• Support of two network technologies:

TCP/IP Ethernet with WebServer functionality allows

monitoring and configuration of controllers through a

standard WebBrowser (e.g. Internet Explorer

or Mozilla

Firefox)

or Echelon FTT10 LON

technology for monitoring and

configuration through a supervisory system such as the

ALCO Monitoring Server EMS

• Alarm messaging by email (EC3-332)

• Integral backup battery to close Electrical Control Valve in

case of power loss

• Electrical connection via plug-in type screw terminals

• Aluminum housing for DIN rail mounting

Features ECD-001 Display Unit

• Front panel mounted human interface for parameter and

status read-out and controller setup via keypad

• 2½ digit LED display with automatic decimal point

• Indicator LEDs for compressor, fan, heater and alarm

• Connection to EC3 Series via ECC-N10 or standard CAT5

patch cord with RJ45 connectors.

• Standard 71 x 29 mm cut-out dimensions

• IP65 protection class when mounted in front panel
