ENABLE. Use the
left (◄)orright(►) arrow button to set the DST schedule
function to OFF, ONCE,orRECURRING. Use ONCE to schedule a specific
calendar date and time to apply or remove the daylight savings time offset. For
example, “2011-03-06 02:00:00.” Use RECURRING to se t up relative dates
and times to apply and remove the DST offset. For example, “1st Sun of Oct
02:00:00.”
CAUTION. Wh
en you change the DST Schedule mode between ENABLE, ONCE,
and RECURRING, any DST offset that is currently being applied will be removed
and any new DST offset that is configured for the new mode will be applied
immediately.
The Offset adjustment allows you to enter a time zone correction of up to ±23:59
hours. However, the ST309 standard only implements codes for time zones in the
range of -12 to +13 hours. Therefore, when the G PS7 module is set to use ST309
data as the Time of Day source, it is recommended that the combined programmed
offset
from time zone and DST be restricted to the range of -12 to +13 hours.
OFFSET. Use this selection to set the DST offset that will be applied when either
the ON
CE event or the DST START event occurs at the user-scheduled time.
Press the ENTER button, and then use the left (◄)orright(►) arrow button to
select a digit in the DST offset value to change. An underline character appears
under the selected o ffset digit. The date and time digits take the following form:
HH:MM. When the DST Schedule function is set to RECURRING, this offset
can only be a positive number.
After you select an offset digit, use the up (▲)ordown(▼) arrow button to
change the value of the digit. Repeat for each digit as required for your offset.
Pr
ess the ENTER to confirm the offset change.
