Relay Base Wiring
Delay on Break Operation: Power is applied to the input terminals (2 and 10) at all times. When
the normally open start switch is closed, the output contacts transfer and remain in this position as
long as the start switch is kept closed. When the start switch is opened, the time delay starts. At the
end of the preset time delay, the output contacts transfer back to their original position and the relay
resets.
