6-4 Memory Initialization
The NT631/NT631C has the following initialization functions. Use them as
necessary.

• Initializing memory tables page 141
• Initializing memory switches page 143
• Initializing display history record data page 137

Reference: If writing to the screen data memory has been disabled by the System Setting
setting in the System Installer mode, memory initialization is not possible.
6-4-1 Clearing Screen Data
Use this function if the screen data has been corrupted and the NT631/
NT631C cannot be started up correctly.
This operation clears (initializes) only the screen data and contents of the cal-
culation tables. The memory switch settings and display history/alarm history
record data are retained.
Press Maintenance Mode.
