In the following example, the case of time schedule number = 0 will be described as an example, but the setting value is not particularly limited. FIG. 5 is a time chart showing the operation of the emergency generator 1 of the present embodiment.
When the control device 20 detects a power failure, the control device 20 determines a power failure confirmation time of 1 second, that is, a time for checking the T1 time shown in FIG. Confirm that there is a power outage. At this time, if it is detected that there is a power failure, the fuel pump is activated to supply fuel to the engine 3.

  Then, after the time T1 has elapsed, the time for driving the preheater 7 is set to 10 seconds, that is, the time T2, and the engine 3 is continuously preheated by the preheater 7 during this time. Thereafter, the cell motor 5 is activated to start the engine 3, and the cell motor 5 operates until a frequency of 12.5 Hz, which is a power generation establishment voltage generated by the generator 2 connected to the engine 3, is detected. Further, the stop solenoid 6 is actuated to start the engine 3 while applying a brake to the engine 3. These priming times of 5 seconds are provided and represented by the period of T3.

Is switched to supply power to the load, and power supply to the load is started.
When detecting that power has been restored, the control device 20 is provided with a power recovery confirmation time of 60 seconds for confirming whether or not power recovery is reliable, that is, a time for checking the time of T4. When the load is confirmed, the load is switched to the normal supply state, and the generator 2 is operated for a period of 120 seconds with no load, that is, T5 with no load connected. Then, the engine 3 is stopped, the stop solenoid 6 is operated, and the engine 3 is gradually stopped. In order to confirm whether or not the engine is completely stopped, a stop confirmation time of 30 seconds, that is, a time for checking the time of T6 is provided.

Here, after pressing different buttons at the same time, the password is entered and when the password matches the previously entered password, the mode is shifted to the special mode ( S5). When a time schedule registration process is selected from a number of processes (S7), the process proceeds to the time schedule registration process (S10), and the process to shift to the special mode is completed.

  Next, in the time schedule registration process (S10), the set times (41 to 48) written in the time schedule rewritable area of the EEPROM 40 are read (S11) and displayed on the LED display part on the operation panel 21. Then, the set time to be changed is written and set (S13), the set time is stored and registered in the rewritable area of the EEPROM 40, and (S15) the time schedule registration process is terminated.

  These operations can be performed with a switch on the operation panel 21. Operation display and display of various modes are displayed on an LED display portion on the operation panel 21. Subsequent operations are performed in the same manner.

  Control device 20 does not operate and waits until a power failure is detected (No in S21). When a power failure is detected (Yes in S21), the time schedule number in which the dip switch 50 is set is confirmed (S23), and when the time schedule number is “No. 15” (Yes in S25). ), The set time data (41 to 48) written in the time schedule rewritable area of the EEPROM 40 is read and set (S27), and the control device 20 controls the device based on the set value.

  On the other hand, when a time schedule number other than “No. 15” is selected (No in S25), the set time data (31 to 38) is read from the time schedule rewritable area of the time schedule number corresponding to the ROM 40, and Data is set (S29), and the control device 20 controls the device based on the set value.
