Controller disabled, waiting for restart
After a major change of the configuration parameters, the rack controller is
disabled for 20 sec. After this delay the controller restart automatically.

Operating Instructions
Visualising Data: WebPages
A TCP/IP Controller-Readme file is available on the www.emersonclimate.eu web-
site 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 EC3-932 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 EC3-932 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 EC3-932 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.
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
The default settings may be modified in the Display configuration 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
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 controller.
This can save a considerable amount of time 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. In addition, a
permanent 30 days log file containing the control temperature at 15 minutes
intervals is stored in the non-volatile memory to be later transferred using FTP to
the computer. The log file can be imported into a standard spreadsheet program
such as Excel. Refer to the TCP/IP Controller-Readme file for a complete
description of the features available for the TCP/IP series of controllers.
