Example of a Switching Contact Application
In this example, the external load will be switched via an external relay triggered
power or time management events.
In this example, the “Default
Switch” is set to “contact 2-1”. If
the external load is also to be
switched in the event of a power
failure, connect the relay to pin 2
and set the “Default Switch” to
“contact 2-2”.
