When power is removed, the timer resets. * Instantaneous contact When power is applied, the NO contact makes instantly. When power is removed, the timer resets. * When power (2-7) is ON, the NO timed contacts (1-3, 8-6) are instantly closed. When power is OFF, they are opened after the set time has elapsed.
