The cursor is moved to the setting field corresponding to step 4 of (1) to (3) and the setting field corresponding to step 4 of the built-in timer to make a selection. Then, in step 5, the setting field corresponding to the arithmetic operation RET for returning the program to the beginning is selected and determined.

The operating time of the above-mentioned built-in timer is set by inputting a numerical value (time) by operating the cursor keys 11 _{1 to} 11 ₄ and finely adjusting the timer time during the program operation by the adjusting unit 11 _{7 including a} variable resistor. It can be adjusted. The outlet 4 ₁ ... and the column of the input terminal 8 ₁ of the column the cursor keys the mark to be displayed in the 11 ₁
To 11 ₄ can be set by moving by operating the indicate that the ON operation in ■ as illustrated is selected set.

The control unit 3 creates a sequence program according to the contents thus selected and determined, and the storage unit 1
Store in B. This stored content is retained until the program is changed or the backup power supply is cut off. Then, after entering the execution mode, the control unit 3 executes the energization control for the lamps or the like connected to the consensus 4 _{1 to} 4 ₃ according to the sequence program stored in the storage unit 1B every time the start switch is operated. become.
