Function Chart:
In the off state, both the Lead Control Switch and the Lag Control Switch are open, the
Alternating Relay is in the LOAD A position, and both loads are off. When the Lead Control
Switch closes, it energizes the first load (M1). The red LED marked "LOAD A" ? glows. As
long as the Lead Control Switch remains closed, M1 remains energized. If the Lag Control
Switch closes, it energizes the second load (M2). When the Lag Control Switch opens, the
second load (M2) is turned off. When the Lead Control Switch opens, the first load (M1) is
turned off and the Alternating Relay toggles to the LOAD B position. When the Lead
Control Switch closes, it turns on the second load (M2). The red LED marked "LOAD B"
glows. If the Lag Control Switch closes, it will energize the first load (M1). When the Lag
Control Switch opens, the first load (M1) is turned off. When the Lead Control Switch opens,
the second load (M2) is turned off, the Alternating Relay toggles back to the LOAD A
position, and the process can be repeated again. NOTE: if the Lag Control Switch does not
close while the Lead Control Switch is closed, the Alternating Relay will act as a normal unit.
