Zusammenfassung: | PURPOSE:To make a jumper connector unnecessary, and to simplify the structure by providing a delay control outlet setting switch for setting a delay time of the time of a cut sequence, on a desired position of a control outlet. CONSTITUTION:When a power source turn-on indicating signal P-ON is inputted by a power source turn-on indicating line 14 of the whole electronic computer system, a power source sequencer 1A executes a power source turn-on control by confirming that a power source turn-on has been completed, as to control outlets N1-N13, respectively, and proceeds to a power source turn-on indication of a control outlet N14. However, since no device is connected to the outlet N14, it is looped by an ON-completion of the outlet N14 and a detecting step of a power source cut-off indicating signal P-OFF. When the signal P-OFF is applied, a power source cut-off indication of the outlet N14 is executed, a set value of a delay control outlet setting switch 17 and the outlet N14 are compared, and in case of dissidence, the power source cut-off indication is executed successively until reaching the outlet N1 from the outlet N13. On the other hand, in case of coincidence, after a delay time which has been set by a delay time setting switch 18, the next powr source cut-off indication is executed. |
