<p>PURPOSE:To minimize the application end time of a power supply control system by using the 1st timer which monitors the maximum application end time of a device set within the system and the minimum 2nd timer which can avoid the peak of a start current. CONSTITUTION:When a power supply is applied, the first device is actuated. Then a timer I 5 is started to monitor the shortest time to avoid a rush current so that no problem is produced despite actuation of the next device. When said minimum time elapses, the following devices are successively applied. When the application of power supply is through with all devices, an application end monitor timer II6 which is set at the device having the largest application end time within a power supply control system. Then the application end of power supply is checked with all devices in the system during the set time of the timer II6. A power supply fault is decided for a device that receives no application of an application end signal even after the set time of the timer II6 comes to an end. This faulty device is registered to complete the power supply application sequence. In such a constitution, a rush current is avoided when a power supply is started and the application end time of system is minimized.</p> |
