4.0 DAYLIGHT SAVING TIME

After setting or modifying the date, display will show:

a. For standard USA daylight savings (DSt), press MODE and go to step 5.0. b. For dates other than standard USA dates, press MONTH and go to step 4.1. c. If daylight saving time (DSt) is NOT required, press DEL display will show:

Press ENTER then go to step 5.0.

4.1 TO MODIFY STANDARD USA DAYLIGHT SAVINGS DATES

NOTE: The ﬁrst two digits represent the month and

the second set of digits represent the week in the month. Choices for week are 01 (1st), 02 (2nd), 03 (3rd) or L (Last) week of the month. The default day

is Sunday (SU.) Once modiﬁed date set, the unit will automatically calculate the correct start dates in the future.

Now press MONTH and DATE buttons to modify the starting DST settings. Pressing D AY changes default day. EXAMPLE: A screen showing “04:01 SU S” repre sents April (04), the ﬁrst week (01), Sunday (SU), and the Start (S) of daylight savings time.

Press ENTER to save and the display will show:

Now press MONTH and DATE buttons to modify the ending DST settings. Pressing DAY changes default day. EXAMPLE: A screen showing “10: L SU E” represents October (10), the Last week (L), Sunday (SU), and the End (E) of daylight savings time.

Press ENTER to save and the display will show the modiﬁed DSt starting date.

Press MODE twice to go to step 5.0.

5.0 DUTY CYCLE AND SIGNAL

The Duty Cycle programming mode begins with a display that shows the ON duration ﬁrst for Duty Cycle 1 and the OFF duration second. Programming both ON and OFF will enable the load to repeatedly turn ON then OFF.

The Signal Timer operation can be used by setting only the ON duration of each duty cycle. Skip the OFF duration entry. The load will turn ON for the duration of the ON period, and it will not be repeated.

Once you’ve selected a cycle time, you need to program the schedule in Section 6.0. Schedule the events whenever you need to start and end the duty cycle or to execute a signal, such as school bells.

If not needed, press the MODE key

5.1 TO SET DUTY CYCLE AND SIGNAL

Press either HOUR, MIN, or SEC keys to set the desired ON duration for the cycle (ON C1).

Press the ENTER key.

a) For signal timer application, press the ENTER key. b) For a cycle program, press the HOUR, MIN, or SEC keys to set the time to the desired OFF duration for the cycle (OFF C1). Press the ENTER key.

Follow the same procedures above to set the second signal or duty cycle entries.

Press MODE key to advance to next screen.

6.0 SCHEDULE SET MODE

Press MODE key until display shows:

6.1 SETTING HOURS AND MINUTES

Note: A schedule is needed for each event. If a typical ON/OFF pair is required, use SCH 01 for the ON event and SCH 02 for the OFF event.

Press the HOUR, and MIN keys to set the desired time. Press EVENT to set desired event (ON or OFF, C1, or C2)

Note: C1 or C2 will not be displayed if the duty cycle durations are not set in Step 5.

Press CH SELECT key to select channel on DG280A.

Press ENTER to save.

Follow the same procedures above to set more schedule entries.

Press MODE when schedules are complete.

7.0 SKIP DAY MODE

The Skip Day programming allows events to be repeated for a certain number of days, and then skipped for a number of days. Both active and skip periods are set by the user from 1 to 31 days. The timer will follow the programmed 24 hour schedule during each day of the active period.

Example: A generator may have an active schedule for 1 day and then skip 29 days to allow operation once a month for testing purposes. On the one active day, a 10 minute schedule may be programmed to start at 4:00am.

The two channels of the DG280A add additional programming capabilities in the Skip Day mode. Alternating days of operation may be set for each channel. This lets one load be active while the second load is skipped.

Example: Two pumps are used to operate at alternate times to extend the life of each pump. An active schedule may be set so Pump A operates 5 days and skip 2 days. Pump B can be set to be active on 2 days and skip the other 5. Care must be taken in programming if the two pumps must not operate at the same time.

If not needed, press the MODE key

7.1 SETTING SKIP DAY MODE

Review the Skip Day carefully before using this feature.

Call the Tork Tech Support line if you have any question on set-up 888-500-4598.

Press MODE until display shows:

Press D/ON button to set the number of days load will be active. The ﬁrst number pair will change.

Press D/OFF button to set the number of days load will skip. The second number pair will change.

Press DAY button to set today’s position within the D/ON and D/OFF pattern. The third number pair will change.
