Programming the Grässlin Digi 42/2 -L Timer

I.              General Description

A.  The circular keypads are positioned to provide a sequential path for programming. Starting with  Prog.  to select a program, clockwise to  hand symbol  to select ON or OFF, then  h  for hour,  m  for minute, and finally  Day  to select day or days of the week.

B.   If an input is missing or incomplete, the missing segments will flash when the  clock symbol  or  Prog.  key is depressed. For example, if no ON or OFF is selected, the ON symbol will flash. The missing entry must be completed before programming can resume.

C.  While programming, pressing the  h  or  m  key longer than 2 seconds will cause a rapid roll of the parameter.

D.   A Program consists of:

1.       An ON or OFF command

2.       Time of Day (Hour and Minute)

3.       Single day or multiple days on which it is to occur.

IMPORTANT:

 

1.     Before proceeding with setting the time and programming the unit, press the reset key  (Res.) to clear all data from the memory.

2.     See “An Example” further down on this page get familiar with typical lighting schedule.

II.             Manual Daylight Time Changeover

The Digi 42/2 offers the manual daylight time changeover in the spring and fall. Depressing the  +/-1h  key sets clock time up or down 1 hour to change the time twice a year

III.            Setting Time and Day of Clock              

IMPORTANT:

 

1.     Before proceeding with setting the time and programming the unit, press the reset key  (Res.) key to clear all data from the memory.

2.     See “An Example” on page 4 to get familiar with typical lighting schedule.

A.            Select military (24:00 hr.) or AM/PM (12:00 hr.) time by depressing and holding  h  key while pressing  +/-1h  key to toggle between military and AM/PM. (AM appears in display when in AM/PM mode.)

B.            Press and hold down  clock symbol            key (do not release until step G).

C.            Press  +/-1h  key once if setting the timer when daylight time is in effect (+1h  appears in display).

D.            Set hour with  h  key.

E.            Set minutes with  m  key.

F.            Press  Day  key repeatedly to the day of the week. (1 is Monday, 7 is Sunday)

G.            Release  clock symbol  key, colon will begin flashing.

YOU HAVE COMPLETED PROGRAMMING.

NOTES:

 

1.     A flashing display indicates either incomplete data entry or the battery is low (2 week, internal battery back-up). Check to see if days and ON or OFF times are entered, and check the power supply to the time control.

2.     The output relays will switch ON (or OFF) only at programmed times. After programming is completed, if a channel should be ON, it must be manually turned ON with the  hand symbol  key. For example, programming is completed at 2PM and CH1 was programmed to be ON at 6AM and OFF at 11PM. After pressing the  clock  key, CH1 will be OFF; press  hand symbol 1  to turn it ON.

V.              Review and Change of Programs

A.            To review a program at any time, press  Prog.  key. Programs will be displayed in the sequence they were entered with repeated presses of  Prog.  key.

B.      To change a program, select the program to be changed with  Prog.  key, and enter the new time of day, and/or days of week just as in the programming steps shown above. The old program is overwritten with the new selections. Press  Prog.  to store the new program.

C.       To delete an individual program, select the program as in step “A” and press the  m  key and then the  h  key until  “--:--”  appears in display. Press either  Prog.  or  clock symbol  key until  “--:--”  flashes. The program is deleted after few seconds.

VI.             Manual Override

While in the  Run  mode, (clock symbol is displayed)

1.             Pressing the  hand symbol  key will reverse the load status (switch load OFF if it is ON, or switch ON if it is OFF). A hand symbol appears in display to indicate the override is active. At the next scheduled switching time, automatic time control will resume, eliminating override.

2.             Pressing the  hand symbol  key a second time, load ON symbol in square brackets appears in the display indicating the load is switched  permanently ON.

3.             Pressing the  hand symbol  key a third time, load OFF symbol in square brackets appears in the display indicating the load is switched  permanently OFF.

4.             Pressing the  hand symbol  key a fourth time returns to automatic, clock symbol appears in the display.

VII.              Manual Daylight Time Changeover

The Digi 42/2 offers the manual daylight time changeover in the spring and fall. Depressing the  +/-1h  key sets   clock time up or down 1 hour to change the time twice a year.
