6. What to Do in Case of Mains Failure
In the event of mains failure, the display shows the
"——:——" symbol for some time before it goes off.
The switching time events programmed by the user
and the current data are kept. The Electronic Time
Switch has a power reserve of approx. 24 hours.
When the mains voltage has reappeared, the last
switching time event in the program memory is exe-
cuted. This moves the lights to the current position as
determined by the program. The programmed data is
kept and the Electronic Time Switch is ready for ser-
vice again.
Example:
Light ON time: 20:15 hrs.
Mains failure at 20:10 hrs.
Mains voltage reappearing at 20:20 hrs.
The last 20:15 hrs. ON switching command is exe-
cuted. The lights go on, the current position is
reached.
For mains failures of longer than 24 hours, the pro-
grammed switching time events are kept.
The current data (time, date) will get lost and must be
re-entered. The display will read 12:00 hrs. and flash.

8. What happens if...
... the astro times do not seem to be executed cor-
rectly or show highdeviations from sunrise and
sunset, respectively?
Check the settings of the date and of the astro time
shifts.
... the operating voltage had failed?
The display shows the --:-- symbol, the 24 hour power
reserve is activated. If the voltage failure is less than
24 hours, the unit resumes the set functions without
any maintenance. After longer voltage failure, the cur-
rent data (time, date) must be re-entered.
... the programmed time events are executed at a
difference of one hour?
Check the summer/winter time setting and correct, if
necessary.
... the unit is to be reset to factory setting?
Make a RESET. Press the SET and MODE keys si-
multaneously for approx. 7 seconds.
...the lighting goes out after some time after hav-
ing been switched on manually?
An automatic switching time event was executed, or
the time switch function (memory C) has lapsed.
