System Maintenance Section 3-9
The screen memory check will start.
While the screen memory is checked, the “Memory checking...” message will
be displayed.
• If the memory check has been normally completed, the “Memory is OK”
message will be displayed.
• To quit the memory check, press the “Cancel” touch switch. The NT20 will
enter the I/O CHECK MENU.
• If the “Memory error!” message is displayed, the screen data memory
may have been used up to its service life or there may be a hardware
fault. In that case, initialize the screen data memory and check the mem-
ory again. If the same error message is displayed again, consult the
OMRON Service Center.
