AUTO - ON for a set interval triggered by applying the supply voltage U or closing of the control contact S
Each application of the supply voltage U or closing of the control contact S while supply voltage U is applied results in immediate switching the R contact on for an adjustable interval T. After the T interval has lapsed, the R contact remains off. Opening and closing of the control contact S within the T interval does not affect the function to be fulfilled.
U - supply voltage; R - output state of the relay; S - control contact state; T - measured time; t - time axis
