• Range A: The time elapses after the trigger coil is deactivated.
• Range B: The stop coil stops the time from elapsing.
• Range C: The reset coil resets the relay and the contact. After the
reset coil drops out, the relay continues to work normally.
• Range D: The reset coil resets the relay and the contact when the
function block is timing out.
