ON-delay
The two-wire timing relay is connec- _A1/A2
ted in series with the load. Timing
begins after application of the excit-
ing voltage. The semiconductor
output then becomes conducting,
and the load is energized.

1) Note on function with start contact: A new control signal at terminal B,
after the operating time has started, resets the operating time to zero. This
does not apply to G, G! and H, H!, which are not retriggerable.
2) This function is indicated on the unit with the identification letter C.

3) For the flashing function, the start between interval D and pulse Di is
selectable.
