6.0 Commissioning (time switch with a DCF antenna)
If a DCF antenna is connected to the time switch, the SEL 173 DCF functions as
a radio time switch. After manual input of the astronomical data (section 5.3) the
radio time switch automatically sets for DCF 77 radio reception the current time,
date and summer / winter time. Otherwise operator control of the radio time
switch is identical to the time switch without a DCF antenna.
Worth knowing:
- Precision with radio reception: + / - 1 sec. in 1 000 000 years.
- Transmitter location: Mainflingen near Frankfurt on Main
- Range of the transmitter: approx. 1000 km
- Synchronization: After commissioning and thereafter daily during the night.
6.1 Connecting and directing the radio antenna
Avoid installation locations in the vicinity of:
- radio transmission installations
- radiological devices
- televisions or personal computers.
We recommend installation locations:
- outside of the control cabinet (at a distance of least 4 m)
- under the roof
- in a protected place in the open air.
Connecting the radio antenna:
–Use a 2-conductor cable for connection
–Connect the antenna to the time switch’s DCF 77 connection terminals.
–Up to ten SEL 173 DCF devices can be connected to the antenna.
–If the LED (DCF 77) lights up, the polarity of this antenna cable has to be
changed over.
Connection of a Theben TR 658 DCF to the same antenna cable
is not allowed.

6.3 Setting the date and time (time switch with DCF antenna)
A. Automatic commissioning
Note: During synchronization do not press any keys !
The synchronization attempt would then be aborted immediately.
To then achieve a restart, the key RES must be pressed again.
1. The display counts from 00 to 59 (see Fig. 2)
Depending on the reception quality of the DCF 77 signals, this
procedure can be repeated several times.
2. If the time switch hsa received two complete signals, the symbol
RC remains and the channel statuses are displayed (see Fig. 3).
The clock is now operative.
B. Manual commissioning
Tip: If the clock does not synchronize itself during commissioning even
after several attempts, possibly due to a disturbed reception signal,
we recommend that you set the date and time as described in
section 5.4. The time switch will then attempt to synchronize itself
with the signal during the night hours.
Example: The time switch has synchronized itself on 19. 5. 2000 at 9.25 h.
6.4 Forced transmitter call
Synchronization of the time switch is effected after commissioning and then daily
between 1.58 h and 3.13 h.
Radio synchronization can also be triggered manually during the day
(transmitter call)
Start of the transmitter call:
1. Press the key Dat for approx. 3 secs.
2. Then release it.
The time switch synchronizes itself with the DCF 77 signal.
The following can be seen on the LCD display:
The symbol RC only flashes during DCF 77 synchronization !
Once the time switch has synchronized itself a program review is effected.
Subsequently the channels adopt the switching statuses determined by the
individual program.
The symbol RC appears on the LCD display permanently.
3)
2)
6.2 Setting astronomical data
The astronomical data must be input during commissioning as described in
section 5.3.

Each channel can be switched manually ON or OFF as a continuous connection.
Acontinuous connection has maximum priority. The channel remains in the
continuous connection position ON or OFF until it is manually reset.
For continuous connection with time limitation ON / OFF see section 9.3.
Example: Switch channel 2 on continuous connection to OFF.
Fig. 1: in auto mode select channel
Fig. 2: select continuous connection for the channel
Fig. 3: 0 = continuous OFF (continuous ON = 1)
70
7.0 Manual intervention into the program
7.1 Continuous connection ON or OFF
7.2 Terminating continuous connection
A continuous connection must be manually terminated. After termination of the
continuous connection the automatic program determines the switching status of
the channels.
Example: Terminate continuous OFF on channel 2.
7.3 Manual ON (switching preselection)
Each channel can be switched on manually in the automatic program.
The symbol H=Hand than appears on the display.
A switch preselection is cancelled again by the next switch command.
The display H goes out.
Select channel: e. g. key 1 =channel C1, key 2 =channel C2.
Select status: key 1 =switch on, key 0=switch off.
Example: channel C2 to switch on manually, press keys 2, 1.

7.4 Manual OFF (switching preselection) 7.5 Disabling / enabling the keyboard
Each channel can be manually switched off in the automatic program.
A switching preselection is corrected again in the automatic program by the next
switch command (the symbol H goes out).
Select channel: Key 1 =Channel C1, key 2 =Channel C2.
Select status: Key 1 =switch on, key 0=switch off.
Example: Channel C2 to switch off manually, press keys 2, 0.
With the Obelisk memory card, operator control of the time switch can be
prevented for unauthorized persons. If the keyboard has been disabled, without an
Obelisk memory card no interrogation of the programming is possible.
To disable the keyboard:
1. Insert the Obelisk memory card into the data interface.
2. Press the key 8 for approx. 4 secs. until the symbol Obelisk flashes.
3. Extract the memory card.
The keyboard is disabled.
Operator control of the time switch:
If the symbol Obelisk flashes after a key has been pressed, the keyboard is
disabled.
1. Insert the Obelisk memory card into the data interface.
The time switch is now normally operable.
2. With key v you can select a program.
3. You can then remove the memory card and continue programming.
The keyboard is disabled again, if the time switch returns to auto mode.
Cancellation of the keyboard disable:
1. Insert the Obelisk memory card into the data interface.
2. Press key 8 for approx. 4 seconds. The symbol Obelisk appears and goes out
again after 4 seconds.
3. Extract the memory card.
The keyboard is enabled.

On channel 1 the astronomical switching has programmed a switch-off time for
each evening. If channel 2 has been activated as an astronomical channel, on
channel 2 a switch-off time has also been programmed for each evening.
Example: programming of a switch-off time for night interruption. Channel C1 should
switch off from Mon. to Fri. at 22:30 h. p.

During commissioning the time switch will have calculated from the astronomical
data the times for sunrise and sunset on each day of a year. Channel 1 of the time
switch switches on at sunset and off at sunrise.
The astronomical switching times can be interrupted or aborted at night, i.e. the
time switch can switch on every day at the beginning of twilight and switch off at
fixed programmed times in the night.
Channel 2 is a switching channel with normal 7-day switching times, date
changeover times and priority switching times. In addition channel 2 can be
activated as an astronomical channel (section 8.6).
The astronomical times cannot be changed. They can, however, be supplemented
separately with an offset for sunrise / sunset (section 8.5).
Every night at 24 h the clock loads the astronomical times for the current day from
the EEPROM.

8.5 Programming an offset
The astronomical switch-on and switch-off times for channel 1 can be separated
from one another by means of the offset by a max. of +/- 120 mins.With the offset
the switching times can be adapted to local circumstances (e.g. shadow of
mountains).
If channel 2 is programmed as an astronomical channel, the same offset for
astronomical switching times is valid as for channel 1.
Caution: The offset for sunrise is not adopted until the offset for the sunset has
been saved in memory.
Example: Switch-off time 30 mins. after sunrise, switch-on time 30 mins. before
sunset.

8.6 Programming astronomical channel 2
After commissioning, channel 2 is programmed as a normal switch channel
without any astronomical function.
Channel 2 can be activated as an astronomical channel. Channel 2 takes the
astronomical switching times and offset from channel 1. However, other night
interruption times than for channel 1 can be programmed.
Note: To shut off the astronomical switching for channel 2, in Fig. 2 press key 0.
9.0 Priority program
Besides the normal 7-day program up to 9 different 7-day programs can be filed
with the SEL 173 DCF.Adefined 7-day program P1 ... P9 can be invoked at
randomly defined time periods.
The programming consists of:
1. Defining the 7-day program, see section 9.1
2. Defining a starting and finishing date, see section 9.2
If the time periods of several weekly programs overlap, the program with the
highest index takes precedence.
For example, the 7-day program P9 is effective before 7-day program P3.
On priority levels 1 to 4 the astronomical times are effective. The priority program
suppresses only the normal switching program.
On priority levels 5 to 9 the astronomical switching times are suppressed and the
programmed day or 7-day program is executed.
Programmable are up to five 7-day programs that switch together with the
astronomical switching times (normal program and priority levels 1 to 4). Also up
to five 7-day programs are programmable that suppress the astronomical
switching times (priority levels 5 to 9).
All 7-day programs can be assigned random time periods in the year.
To maintain an overview we recommend that the different 7-day programs in the
table be noted at the end of the operating instructions.
Switching times are executed in accordance with the following order of
precedence:
–Continuous connection
–Continuous connection with time limitation, section 9.3
(Off has precedence over On)
–Date switching times, section 8.3 (Off has precedence over On)
–One-off switching times, section 8.4
–7-day program with priority, sections 9.1/9.2 (P9 has precedence over P1)
–7-day program, section 8.1/8.2
