10.1.3 Auto(matic) Display-Revert Time
While the Execution/Setup display, or any other display that is positioned lower than the
Execution/Setup display (see Figure 7.3.1, earlier in this manual), is displayed, if there is
no key entry from the touchpanel for a certain time, the current display will automati-
cally return to the basic panel display. This action is referred to as “auto return.”
The “auto return” time setting starts from no key entry to the return to automatic return.
The “auto return” time can be set from 0 to 255 minutes. If 0 is set, there will be no
automatic return. By default, the “auto return” time is set to 0 (zero).
To set the “auto return” time, follow these steps:
(1) Select the Setup key from the basic panel display to display the Execution/Setup
display. Then select Maintenance from the Execution/Setup display.
(2) Select the Display setup from the Maintenance display.
(3) Select Auto return time. The numeric-data entry display then appears.
(4) Enter your desired automatic return time. If you want to set “one hour,” enter 060.
