6.6.3. Time Synchronization Validation

At a pre-determined time of the day and day of the week (see How to Setup Time Synchronization Schedules), the Auto-Sync Time Clock can be set to confirm or validate that a time/date synchronization signal has been received. This is called time synchronization or “Signal Validation".

The factory default time validation is set for 00:00 or (12:00 AM midnight), Sunday through Saturday. Time Signal Validation sync schedules 2 thru 8 are set via the web interface. Each schedule template can be set to run a minimum of every 120 minutes, with a maximum of once every 1439 minutes (see Figure 4-21).

These schedules can be used to alert the user that a date/time synchronization signal has not been received. If a successful time validation does not occur within a 24 hour period, the Auto-Sync Time Clock will flash six day indicators (cursors), while the day indicator associated with the current day of the week will not flash (see Figure 6-8).

Figure 6-8. Failed Time Synchronization Display.

In addition to the flashing day indicators, during the print cycle, the clock will print a block () instead of an “s” at the end of a print line to indicate that this failed time sync condition has occurred (see the following example).

Print Example = 2008/07/08 18:30 15

Seconds must be selected to be printed for this error message to be seen.

6.6.4. Error Messages

In the event of an error, a message will appear in the display. The possible error messages are listed in the following Table along with their probable causes and solutions.
