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.
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 60742). Do not ground the 24VAC lines. We recommend to use one
transformer per EC3 controller and to use separate transformers for 3
controllers, to avoid possible interference or grounding problems in the power
supply. Connecting any EC3 inputs to mains voltage will permanently damage the
EC3.
Setup and Parameter Modification Using the Keypad of the
ECD-000
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.
Alternatively, the parameters can be accessed via the 4-button keypad. The
configuration parameters are protected by a numerical password. The default
password is "12". To select the parameter configuration:
Press the PRG button for more than 5 seconds
•
A flashing 0 is displayed
Press
or
until 12 is displayed; (password)
•
Press SEL to confirm password
•
The first modifiable parameter code is displayed (/1).
To modify parameters see Parameters modification below.
Parameter Modification: Procedure

party
Press
or
to select the function. The number of special functions is dynamic
•
and controller dependent. See list below.
Press SEL to activate the function without leaving the special function mode.
•
Press PRG to activate the function and leave the special function mode.
•
Most of the Special Functions work in a toggle mode, the first call activates the
function, and the second call deactivates the function.
The indication of the function can only be displayed after exiting the special
function mode.
• 0: Display test function
• 1: Displays the current TCP/IP address
• 2: 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.
• 3: Resets all parameters to the factory default setting. The controller will
indicate "oF" during the reset.
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
