Design of the new AlphaRex3
The Next Generation
The AlphaRex3 family of programmable digital time
switches make your life easier:
Unified, simplified, brilliantly conceived – from the standardised design to the high-­
resolution display.
One data key for all AlphaRex3 products for quick and easy transfer of programs to other
time switches and/or for creating backup copies.
This allows you to work efficiently, conveniently and economically.
The function buttons and the
clearly arranged display with
backlight are the same for
all time switches – once you
have mastered one, you can
operate any model, regardless of which time switch
and which application your
customers require.
The intuitive menu-based
operation is easy to learn
and makes programming
extremely simple.
Overview of weekly
programs
The time switch technology of the AlphaRex3 series features first class performance that
is suitable for everyday use.
Programming that is simple and precise to the second with extremely high clock
­precision.

Weekly programs
To create a weekly program, select “MENU”, “PROGRAM”, and then “CREATE” to easily enter programs which are repeated on a weekly
basis. A weekly program consists of a switch-on/switch-off times and days which are assigned as “switched-on” or “switched-off”. The
following predefined blocks can be selected: “MONDAY – SUNDAY”, “MONDAY – FRIDAY” 1) or “SATURDAY – SUNDAY”,1); the assigned
days of the week are fixed. The switch-on/switch-off times must be entered. The user can also set custom day blocks. By selecting
“CUSTOM”, switch times can be freely assigned to any days of the week. This option also allows the user to set switch times at midnight.

Yearly programs [AlphaRex3 DY21, AlphaRex3 DY22, AstroRex DY64]
This menu item allows the user to enter (additional) yearly programs, which are only executed within a defined validity period. They can
overlap with one another and with the weekly programs on the same channel based on an “OR” connective. The validity period is defined
by entering the start date (at 00:00:00) and the end date (at 24:00:00). The start date must be entered before the end date. With the
“EVERY YEAR” option, the additional switch times have the same validity period each year (Christmas, national holidays, birthdays, etc.)
Select the “ONCE” option when additional switch times are needed within a validity period (e.g. during holidays), but the start/end dates
of the holiday period change from year to year.

Special programs (priority program) [AlphaRex3 DY21, AlphaRex3 DY22, AstroRex DY64]
Weekly and yearly programs on the same channel are not executed during the validity period of a special program. However, other special
programs can be executed during the validity period. Different special programs can overlap with each other based on an “OR” connective. With the “EVERY YEAR” option, the additional switch times have the same validity period each year (Christmas, national holidays,
birthdays, etc.). Select the “ONCE” option when additional switch times are needed within a validity period (e.g. during holidays), but the
start/end dates of the holiday period change from year to year. Additional options include “MON TO SUN”/“CUSTOM”: the respective
channel only switches according to the special program; “PROG ON”/“PROG OFF”: the respective channel is switched on/off during this
time period.

AstroRex DY64
If the supply voltage is switched on, the “KEY – READ – WRITE”
menu item is automatically opened when a data key is inserted.
“WRITE”: Program data is written from the time switch to the key.
Caution: Any data present on the key will be overwritten. “READ”:
Program data is written from the key to the time switch; any
switching programs on the time switch are overwritten. Only one
master switching program, which consists of multiple switching
programs, can be saved on the time switch or on the key at a time.
If the supply voltage is not connected, the “KEY – READ – WRITE”
menu item is not automatically opened when a data key is
inserted. The “KEY” function can still be selected from the
menu even if the supply voltage is not connected.
n PC programming
In addition to the easy, text-guided programming directly on
the time switch, switching programs can also be created on a
PC with the software program from Legrand and transferred to
the time switch using a data key. A data transfer device (cat. no.:
4 128 73) is required to transfer switching programs created on
a PC to the data key. The device is connected to the PC using
the USB plug. In addition to the data transfer device, we also
offer a CD with the software and the necessary drivers. PC
system requirements: USB port; Windows® XP, Windows® Vista,
Windows® 7; approx. 40 MB of free memory.
n Basic functions for “astro”
Location (astro) [AlphaRex3 D21 astro, AlphaRex3 D22 astro, AlphaRex3 DY21, AlphaRex3 DY22, AstroRex DY64]
The sunrise/sunset times, which change daily, are calculated for the location programmed in the AlphaRex. The unit is delivered with
the location set to “GERMANY – SOEST” by default. Enter the actual location for optimal operation. This can be done in two ways.
Select “MENU”, “SET” and “ASTRO” to access the two options “LOCATION” and “COORDINATES”. “LOCATION”: With this menu item,
the user can select the country and city which is closest to the site of operation. “COORDINATES”: Alternatively, the user can select
this menu item to set the geographical coordinates of the location. The longitude and latitude values are entered in degrees or
degrees and arcminutes 2) (precision can be set in expert mode). Information on coordinates and time zones can be found in the time
zone map included with every time switch.
Offset
By selecting “MENU”, “SET”, “ASTRO” and “OFFSET”, time differentials can be set for the calculated switch times. This can be done
in two ways: time offset or angle offset.
In time offset, a time differential can be entered to shift the switch time by up to +/- 120 min relative to the sunrise/sunset times.
In angle offset 2), a value can be entered in degrees and arcminutes to shift the switch time by up to +/- 12° 00´ relative to the sunrise/
sunset times. The time differentials are set separately for sunrise and sunset using the menu items “SUNSET” (opens the screen for
setting the sunset offset) and “SUNRISE” (opens the screen for setting the sunrise offset).

Note:
If the offset is set in degrees, the time switch always switches at
points when the brightness is the same, despite the fact that the
twilight duration changes over the course of the year. Sunrise and
sunset correspond to -50' for the centre of the sun (the edge of
the sun is visible on the horizon).
Offset correction function 2)
Select “MENU”, “SET”, “ASTRO” and “CORRECTION” to set a time correction for the 6-month periods surrounding summer and winter.
The time correction is set to 0 min. by default and can be set from 1 min. up to 30 min. The time correction for sunset is entered in the
“SUNSET” menu item. The time correction for sunrise is set in the “SUNRISE” menu item. The correction function overlaps with the
calculated astronomical switch times, including the offset settings.
Example:
Setting a time correction extends the daily switched-on time by up to 60 min. in the middle of the six winter months (switches off up to
30 min. later in the morning and switches on up to 30 min. earlier in the evening). In the middle of the six summer months, the time
correction reduces the daily switched-on time by up to 60 min. (switches off up to 30 min. earlier in the morning and switches on up to
30 min. later in the evening). The time correction varies continuously between the two max. values during the rest of the year.
Basic settings using a PC and day key
All of the basic settings described above, with the exception of the current time and date, can be set up using the AlphaSoft software

from Legrand and imported to the time switch using the data key.

Relay function
The relay state can be changed by selecting “MENU” and “FUNCTIONS”. The relay is preset to the “AUTO” function; the time switch switches
at the programmed times. The following can also be selected: “ALWAYS ON”, “ALWAYS OFF” and “EXTRA”. If “EXTRA” is selected, the
switching status specified by the program is inverted. The time switch resumes switching according to the programmed switch times after the
next switch command.
Holiday program
In holiday program, the holiday period is set with a start and an end date. It can be activated with the “ACTIVE” program item and deactivated with “PASSIVE”. If the holiday program is activated, the time switch does not carry out any programmed switch commands during this
time period. Instead, it remains “ALWAYS OFF” or “ALWAYS ON” during the holiday period, as requested. When the holiday period has ended,
the time switch resumes switching according to the programmed switch times.
1 h test
The “1 h TEST” function can be used for a switching simulation. If “1 h TEST” is activated, the switch outputs are switched for one hour.
After the time has ended, the time switch resumes switching according to the programmed switch times.
PIN code
Input and programming can be locked using a four-digit “PIN CODE”. The time switch can be unlocked using the “PIN CODE”. The time
switch can also be unlocked using the “RESET” function, which also deletes all settings and programs.
Operating hours counter
This function displays the time for which the relay has been switched on and the date of the last reset. Counting range: 65,535 h.

Control input with switch-off delay
Adjustable switch-off delay via control input. The control input enables an additional switching of the relay, parallel to the switching program.
The switch-off delay can be set from 0 s to 23 h 59 min 59 s. The switch-off delay begins as soon as the voltage is removed from the control
input.
Control input “extra”*
Override of switching state via control input. If the “EXTRA” function is activated, the switching state specified by the program is inverted.
The time switch resumes switching according to the programmed switch times after the next switch command. The “EXTRA” function is
ended prematurely if the button is pressed again or if a pulse is received at the control input.

function emit a pre-warning signal sequence, in which the light
switches off briefly (approx. 0.3 s) two times, approximately
25 seconds before the light is switched off. This gives the user
with the chance to reach the light switch in enough time to switch
the light back on. For systems that use fluorescent lamps and
energy-saving lamps, the period of time when the light is

Automatic switching for summer/winter time (daylight saving
time):
The switching dates programmed into the time switch are valid for
Central Europe. The switches occur at 2:00 a.m. CET or 3:00 a.m.
CEST. The time switch sets itself to the correct time in fast-run mode.
Automatic setting during startup:
When the mains voltage returns after a power failure, the time switch
automatically sets itself to the current time. As with the automatic
BST/DST switch, this setting is performed in fast-run mode.
Manual setting:
The time switch setting should not be changed while the power supply
is connected or while the time switch is in fast-run mode. This could
cause an incorrect time to be displayed later. The internal clock
mechanism cannot be influenced by external forces in any way. If the
clock hand is incorrectly positioned, this can be corrected manually
while the supply voltage is connected and after the automatic setting
process is completed (LED is on or flashing).
Switching program during fast-run mode:
In fast-run mode, the set switching program is executed at
a significantly increased speed.
LED off
No supply voltage or, if the supply voltage is connected, the time
switch is in automatic setting mode. No current time.
LED on
The automatic setting process is completed and the BST/DST switch
is activated. The time can be corrected manually if it is incorrect.
LED flashes
The automatic BST/DST switch is permanently deactivated, e.g. due
to damage to the internal electronics caused by overvoltage.
The time switch can continue to be operated with quartz-controlled
precision and no running reserve.
The time switch can only be corrected and set manually.
