FAQ (Frequently asked question)
Functional overview and meaning of pictograms
Daily program
|
||
| Irrespective of the day of the week the same switching program is carried out each day. Multiple switching functions can be programmed within 24h. |  |
Weekly program
|
||
| Depending on the day of the week (Mo - Su) different daily programs can be configured. Unrestricted block programming allows a free choice of days of the week within one switching function. The choice of switching functions is the following: ON, OFF, permanent by date (holiday), pulse (pulse not available in astro time switches). |  |
Astro / Solar program
|
||
| Astronomical or solar time switches can be used as an alterative to twilight switches (also known as photo-electric or day/night switch). When using an astro time switch NO light sensor is needed. By means of “astro switching times” (Astro ON / Astro OFF) the time switch automatically calculates the start of dusk in the evening or the beginning of dawn in the morning and calculates the time for sunset and sunrise respectively. This calculation is updated each day throughout the whole year. Additionally, conventional switching functions of a weekly time switch can be programmed (ON, OFF, (holiday) permanent by date). Offset: A chronological offset can be entered. This offset customises the astro switching times. Therefore the time switch can execute an astro switching time either before or after sunset/sunrise or, if the offset is left at zero, exactly at sunrise/sunset. Position/location: To guarantee exact calculation of local sunset and sunrise times, you can easily enter your approximate geographical position by choosing one of the pre-defined cities or alternatively your exact geographical position by entering the geographical coordinates (longitude and latitude). |

Yearly program
|
||
| Yearly time switches are suitable to achieve more sophisticated time controls compared to standard weekly programs. By means of special (weekly) programs different weekly programs can be carried out within different periods during the year (from start date to end date). Easter function: One additional function when carrying out a special weekly program is the so called Easter function. If you selected it for a period with start date and end date, these dates are shifted by the shift of Easter holiday for successive years (Gaussian Easter formula). This function is applicable for holidays e.g. Ash Wednesday, Palm Sunday, Maundy Thursday, Good Friday, Easter Day, Pentecost, Feast of Corpus Christi, Carnival. Extra switching time: A further feature is the so called extra switching times. Single switching times can be programmed for a specific date (e.g. Anniversary). The residual switching program remains unaffected. A helpful add-on is the option “weekday function”. If you assign this to your extra switching time the shift of this weekday of the month will be taken into account for successive years. E.g.: A switching time that should be carried out every 2nd Saturday of February every year. |
 |
Permanent by date (holiday function) |
| You have the possibility to switch a channel during a period (from start date to end date) permanently ON or OFF. |
Pulse function
|
| The pulse function is a function for a switching time with defined pulse length ranging from 00:01 to 59:59 mm:ss. |
Timer function
|
| The timer function can only be started by an external signal (external input) or by the channel buttons of the time switch. The switching performance is identical to the pulse function. The pulse length is greater and ranges from 0:00:01 h:mm:ss to 9:59:59 h:mm:ss. The timer function is also known under following terms: On-pulse or Single shot. |
Cycle function
|
| The cycle function can be used to program a continuous ON-OFF-ON-OFF….. switching time. The time switch operates then as an asymmetrical recycler (pulse/pause). The independently adjustable max pulse/pause lengths are 9:59:59 h:mm:ss. 4 different memory locations are reserved for 4 different cycles. |
Channel button |
| You can assign different switching functions to each single channel. This function is carried out when either pressing the corresponding channel button of the time switch or optionally by addressing the channel from the external input. The different switching functions are the following: ON/OFF (predefined setting, see also “manual override”), cycle, timer, permanent. |
External input
|
| The external input can be used as external trigger for different functions (ON/OFF, cycle, timer, permanent) [SC 24 => ON/OFF]. The signal connected to the external input can be of type “switch” or “push-button”. Staircase lighting timer: When using the timer function and advanced warning function. Glow lamp load of the external input: Max. 75mA (Used to supply the glow lamp in suitable light switches) (Not available in 70 mm version) |
Advance warning function
|
| A useful function for lighting applications according DIN 18015-2. Two-fold flashing warns of darkness. |
Radio controlled clock
|
| Some time switches can be controlled by radio receiver FU 20 pro (accessory). The time switch is then synchronised to the time standard signal DCF77. The transmitter is located close to Frankfurt/Main (Mainflingen. The range is approx. 1500 km. |
Data-key function
|
|
Time switches with this function can be programmed by data-key DKpro (accessory). |

PIN-Code
|
| Security by PIN-coding |
Display with back light
|
| For a better contrast of displayed symbols, digits and letters |
Permanently ON and OFF (manual) |
| By pressing the corresponding channel button for more than 3 sec. the channel is permanently switched ON or OFF. |
Manual override |
| By pushing the channel button the corresponding channel will change ist status. |
Time counter
|
| Time switches with integrated time counter are counting operation hours and the number of switchings of each channel as well as the operation hours of the time switch. |
