Each timezone lasts from the time
specified in the Time field of one entry and
up to the time specified in the Time field of
the next entry (all entries are arranged in the
ascending order of Time field values). The
following example illustrates this.
Supposing that you have three entries
as shown on the Figure to the left. This
means that there are three timezones: the
first one is from 8:00:00 to 10:00:00, the
second one is from 10:00:00 to 17:30:00, and the third one is from 17:30:00 and up to 8:00:00 of the next
day (timezones do “wrap around”).
One interesting side effect of wrapping around is that if you only have one entry in the
table (for example, 13:15:00) then this entry will be in effect around the clock, because it will work from
13:15:00 of one day to 13:15:00 of the next day, and so on. Therefore, it doesn’t matter what time you will
specify for a single entry in the
table- it still will work around the clock. Setting it to 13:15:00
will be no different from setting it to 18:00:00. This can be use to make the TR40xx always return the
selection to the desired event.
Event field value corresponds to the function key number on the TR40xx’s keypad that is used to select
this event. For the above example, the IN (
F1
) event will be pre-selected between 8:00:00 and 10:00:00 and
the OUT (
F2
) event will be pre-selected between 17:30:00 and 08:00:00 of the next day.
Setting the value of the Event field to 0 disables default event pre-selection for a specified timezone.
Therefore, the TR40xx will not be selecting any event automatically between 10:00:00 and 17:30:00. The
Terminal will simply keep the last event selected by the User during this time.
