ASTRONOMIC TIME SWITCH
ASTRO SAT
INSTRUCTIONS FOR USE
The ASTRO SAT is a digital astronomic time switch that is designed for controlling
any electrical installation that requires a solar reference, specifically the times of
dawn and dusk at a given location throughout the year. It includes the option to
perform operations at a specific time of the day as well as carrying out switching on
and off at sunrise and sunset. During astronomic operations, it is possible to set a
correction of up to ± 9 hours 59 minutes for Channel C1 and C2.
Moreover, it includes another series of additional functions such as: automatic
summer-winter time change, holiday period from 1 to 99 days, adjustable screen
brightness and updating from an infrared remote control.
The menus can appear in several languages and they display a chronogram on
screen that shows the programming for the current day.
To view the chronogram, as well as the other unit configurations, it is only necessary
to repeatedly press the key (info) until the desired display isobtained.
It has two independent switched voltage-free circuits that allow the programming of
up to 70 operations between Channel 1 and/or Channel 2.
INSTALLATION
WARNING: installation and mounting of electric apparatus shall be carried out by
an authorised installer.
ALL POWER MUST BE REMOVED BEFORE PROCEEDING WITH THE INSTALLATION,.
The unit is internally protected from interference by a safety circuit. However,
certain particularly strong fields can alter its operation. Interference can be avoided
if the following installation rules are followed:
- The unit should not be installed next to inductive loads (motors, transformers and
contactors etc.)
- It is recommended to provide a separate line for the supply (if necessary,
equipped with a mains filter).
- Inductive loads must be fitted with interference suppressors (varistor, RC filter).
If the time switch is used in combination with other units at an installation, it is
necessary to check that the assembly so formed does not generate parasitic
interference.
THE POWER SHALL ONLY BE RESTORED WHEN THE EQUIPMENT IS COMPLETELY
INSTALLED.
MOUNTING
Electronic control device for independent installation in distribution cabinet fitted
with symmetrical 35 mm profile in accordance with the standard EN 60715 (DIN
Rail EN 60715 (Rail DIN).
CONNECTION:
Connect the mains supply according to the following schematic:
The Line and Neutral position must be respected, checking the connections made.
A wrong connection can destroy the unit.
PUTTING INTO SERVICE
For the device to be able to execute control over the installation, IT MUST BE
POWERED UP.
The display will light up and the MAIN screen will appear.
When the equipment is switched off, the screen will also go off, but the date, time
and all programming will be maintained during the four-year lifetime of the
incorporated lithium battery.
In this case, if any key is pressed, the display will temporarily switch on to allow
programming. If no keys are pressed during fifteen seconds, the display will be
switched off again.
The unit includes four keys for adjustment and programming.
The following information is shown on the screen:
•
Full date and time
•
Times of SUNRISE and SUNSET for this day with associated symbol:

PROGRAMMING
Programming is based on menus and submenus that are moved through move to
program operations or make adjustments to the unit. Access to the main menu
from the idle screen is by pressing the
√
key. The
▼
and
▲

step through the various menus, which can be entered by pressing the
√
key. To
go back to the previous menu, press
C
.
The data to be entered always appear flashing on the screen.
The structure of the menus is as follows:
MAIN MENU
•
ZONE.
This allows the selection of the city closest to the current location from
list of cities. The astronomic switch will calculate sunrise and sunset for each
day of the year based on the current geographic location.
Astronomic correction:
When the city is selected, SUNRISE and SUNSET
times can be corrected for adaptation to the various topographic conditions (for
example: fencing and shadows of nearby buildings etc).
•
PROGRAMS.
This menu is used to program the various operations. There are
70 memory locations (PROG_01 to PROG_70).
o
ENTER
. The
▼
and
▲
keys are used to change from PROG_01 to
PROG_70. When one is selected, it is entered by pressing
√
. Once inside the
program, the following options are available:
-
EDIT. “PROG_01: EDIT” is displayed and when accepted by pressing
√
“TYPE” appears on the screen. The
▼
and
▲
keys are used to select the
type of operation: C1: ON, C1: OFF, C2: ON, C2: OFF, This is accepted
with
√
. The type of operation is similarly selected:
o
FIXED: The operation is performed at a preset time.
o
SUNRISE: The operation is performed at sunrise. A correction can
be applied to sunrise time.
o
SUNSET: The operation is performed at sunset. A correction can be
applied to sunset time.
This is followed by selecting the hour, minute and combination of days of
the week for the operation.
-

-
PASTE. Pastes the previously copied operation.
-
DELETE. Deletes the selected program.
o
ERASE
. This will erase all operations for the 70 programs in a single step.
•
