The time period begins when the trigger con- tact is opened. The r elay releases at the end of the set delay time or when the power supply is disconnect- ed. The relay operates again when the input contact is closed again. If it is closed before the end of the delay time the r elay keeps ON, a new time period begins as soon as the trigger contact is opened again. Additional Load It's possible to wire an addi- tional load (i.e. a r elay) between pins Y1 and A2, or 5 and 10, driven by the trig - ger contact without damag- ing the device (see wiring diagram).
