3RP, 7PV Timing Relays

7/47

Siemens LV 1 T · 2006

General data

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) For function diagrams showing the various possibilities of operation of the

3RP15 60-1S.30 (see Page 7/48).
