The time period begins when the trigger contact is opened. The relay releases at the end of the set delay time or when the power supply is disconnected. The relay operates again when the trigger contact is closed again. If it is closed before the end of the delay time the relay keeps ON,a new time period begins as soon as the trigger contact is opened again.
