Typical Installations
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.
To eliminate any bounce condition of the Control Switch, the addition of a second switch (OFF) along with two auxiliary contacts is
recommended as shown in Figure B.
