ECx-400 Series devices and Allure EC-Smart-Vue sensors are factory-set with the EOL set to OFF by default.
If inserting multiple wires in the terminals, ensure to properly twist wires together prior to inserting them into the terminal connectors.

Device Addressing
The Subnet ID Address must be set to one (1) or two (2) by setting the DIP switch located on the faceplate An example of how to set the device's Subnet
ID Address DIP switch is shown below.
The address is the sum of the numbers set to ON. For example, if the second (2) DIP switch is set to ON, the I/O Extension Module address is two (2).
Only addresses 1 and 2 are valid.
