DESCRIPTION
ASTRO LOG is a time switch designed to control lighting based on sunrises and
sunsets hours. Includes a programme which automatically adjusts, every day, the
turning on (sunset) and off (sunrise) of lights, without the need of maintenance.
The reduced size of the time switch, only two mudules, makes it ideal for
installation in control panels with limited space availability. The device includes two
independent circuits that can be programmed with astronomic or with fixed times.
INSTALLATION
ATTENTION: Electrical devices must be installed and assembled by authorized
installer.
DISCONECT THE MAINS SUPPLY BEFORE INSTALLING THE DEVICE.
VERY IMPORTANT: This time switch is protected internally against interference by
a safety device. However, particularly strong electromagnetic fields may alter its
operation. Such interference can be avoided by adhering to the following
recommendations during installation:
- The device should not be installed near inductive loads (motors,
transformers, contactors, etc)
- A separate power line is recommended (equipped with a network filter if
necessary)
- Inductive loads should be equipped with interference suppressors (varistor,
RC filter)
If the time switch is to be used in combination with other devices in an installation,
it is necessary to verify that no parasitic disturbances will be caused by the group.
MOUNTING: In cabinets provided with 35 mm simetric rail in accordance with EN 60715.
CONNECTION:
Connect according with the following schema:

STARTING UP AND INSTALLATION
In all the programming subclauses, the following rules applies:
- The data to be modified is identified by blinking.
- Pressing keys ∆ and ∇, the data is incremented or decremented. Keeping
the key pressed, the ratio of increment/decrement is five units per second.
- After last data has been confirmed by pressing key OK, if no other key is
pressed for 1 minute, the programm returns to normal working mode: the
display shows the current time, date and the state of circuits C1 and C2.
RESET
By pressing at the same time the four keys during 3 seconds, the device loose all
data and goes to menu LANGUAGE.
LANGUAGE SELECTION
Press OK to enter MENU LANGUAJE and with keys ∆ and ∇ select the desired
language and validate with key "OK". The device enters to program DATE YEAR.

CLOCK SETTING
For clock setting, press key "OK" to access to MENU PROGRAM and with keys ∆
and ∇ select MENU DATE, validate with "OK" it enters in DATE YEAR, display
shows blinking the digits of the year, update the year by pressing keys ∆ and ∇
and validate it with key "OK". The same operation should be made to update
MONTH, DAY, DAY OF THE WEEK, HOUR, MINUTE and, then validates with
"OK" and the it enters to ZONE LATITUDE. Introduce the data of the latitude where
the time switch is installed according with the geographic situation and press OK.
Then introduce the time for sunrise of the installation situation (DAWN), and
validate with OK, then in the same way with the time for sunset (DUSK). The time
for sunrise and sunset can be displayed in normal mode by pressing key "C", then
the display shows AST and the time for sunrise and sunset of the current day.
CHANGING THE GEOGRAPHIC AREA
If the latitude or the time of sunrise or sunset has to be changed, enter MENU
ZONE and proceed with the needed changes in parameters.
PROGRAMMING
In normal mode, press key OK and enter in MENU PROGRAM; pressing again
OK, the display shows PROGRAM ENTER. Press OK and it shows PROGRAM
PROG: 01, if it is intended to programm a switching in this position then press OK
and it shows PROG: 01 ENTER, then press again OK and select the circuit:
C1:ON, C1:OFF, C2:ON and C2:OFF. Validate the selection with OK and then
select the type of switching we want to programm: fixed time, Astronomic for
sunrise time or Astronomic for sunset time.
FIXED TIME SWITCHING
If the switching selection is a fixed time, press OK and programm the hour,
minutes, day or days of the week by validating or not, day by day, when it is
intended to execute the switching and validate with OK. If, when validating the last
day of the week, the key OK is kept pressed, the programmed switching is
considered as festivity; the display shows HOLIDAYS and the symbol "
after validating with OK, it shows PROGRAM PROG:02.
ASTRONOMIC TIME SWITCHING
After having selected the circuit and the type of switching (C1:ON, C1:OFF, C2:ON
or C2:OFF), then select the desired astronomic switching sunrise or sunset, and
here it is possible to correct the time for sunrise or sunset (offset). If we agree with
the data shown in display, maintain the correction to zero and validate hour and
minutes with OK. If we want to correct it (more or less time), programm the
correction time (up to ± 9 hours 59 minutes), then the display shows the time when
the astronomic switching will be executed, validate with OK and then select the day
or the days of the week the switching has to be executed. If, when validating the
last day of the week, the key OK is kept pressed, the programmed swithing is
considered as festivity; the display shows HOLIDAYS and the symbol "
IMPORTANT: If any switching is programmed as FESTIVITY, then the
programm HOLIDAYS cannot be used and it is removed from menu
remaining as FESTIVITY period.
If several switching are programmed in the same circuit, astronomic (sunrise –
sunset) and fixed times, please observe that they can overlap as the astronomic
switching times move during the year, being possible to produce inappropiate
switchings.
For instance: We want to switch on a shop window when sunset (astronomic
switching) and switch it off at 21:30 hours (fixed time switching). As the switch on
astronomic switching moves on during Summer, then there will be a day when
sunset is later than 21:30, and then the switch on is executed later than the
switching programmed for switch off, then this off is not executed and the circuit
remains on until the next off programmed switching.
This situation can be avoided by conecting in series the two circuits or by
programming an aditional security off switching at a time later than sunset time.
PRIORITY
If two oposite switchings has to be executed at the same moment, ASTRO LOG
always execute the OFF switching.
VIEWING PROGRAMMED SWITCHINGS
Press OK to enter MENU PROGRAM, then press again OK and display shows
PROGRAM ENTER and by pressing again OK, enter in PROGRAMM PROG:01,
then by pressing keys ∆ and ∇ the programs 1 to 22 can be viewed.
CHRONOGRAM
From normal mode and by pressing two times the key "C" you can see in display
the state of circuit C1 and its programmed switching in the chronogram. To view
the state of circuit C2, press again key "C".
EDITING OR DELETING SWITCHINGS
Press OK to enter MENU PROGRAM, then press again OK and display shows
PROGRAM ENTER and by pressing again OK, enter in PROGRAMM PROG:01,
then by pressing keys ∆ and ∇ select program to edit or delete and validate with
OK. Then display shows the selected programm and PROG:xx ENTER, if we want
to edit then acept by pressing OK and proceed as in subclause PROGRAMMING.
If you want to delete it, select ERASE with keys ∆ and ∇ and validate with OK.
DELETING ALL THE SWITCHINGS
Press OK to enter MENU PROGRAM, then press again OK and display shows
PROGRAM ENTER, with keys ∆ and ∇ select PROGRAM ERASE, validate with
OK and then it appears ERASE ALL: NO, with ∆ and ∇ select ERASE ALL:YES
and acept with OK.
MANUAL OVERRIDE
In normal mode, pressing key ∆, circuit C1 is activated or deactivated. The same
for circuit C2 by using key ∇.
PERMANENT OVERRIDE
Enter in MENU PERMANENT. Validate with OK and the display shows
PERMANENT C1:YES, with keys ∆ and ∇ select: C1: YES, C1:NO, C2:YES or
C2:NO, according with the circuit intented to activate or deactivate in a permanent
way. The selected circuit remains in the selected position as far as it is changed in
the same way.
If the permanent override is active, it is possible to change its state (from ON to
OFF or vice versa) with the manual activation key (
to the circuit but maintaning the permanent state. In this permanent state, no
programed switching is executed. If a circuit is in permanent override state, it is
indicated with the corresponding symbol "
