8.3.8.2 DCF77 (Optional Hardware necessary)
The signal generation for the output of a DCF77 pulse (1Hz) may be configured in this panel.
For the output of this signal additional hardware (at system level) is re-
quired (see system manual if applicable).
8.3.8.2.1 Timebase
Timebase
Local Time
Standard Time
UTC Time
In general the local time is set as the base. This time leaps forward/back 1 hour every daylight
saving time changeover. The standard or UTC time must be selected as the base if automatic
daylight saving time changeover shall be suppressed.
When setting standard time (winter time), the time offset to local summer time is minus 1 hour.
Standard time runs continuously (without time leap) throughout the whole year.
When setting UTC, the world time (formerly GMT) is used as the time base. This time base
also runs continuously (without time leap) throughout the whole year.
8.3.8.2.2 Output if blocked
Using this menu item the interference reaction of the DCF77 pulse can be controlled unless
the system status is lower than the reference value.
Fault signal
2 Hz Pulse:
If the system status is lower than the reference value, a 2Hz
pulse instead of the DCF77 pulse is provided.
No Signal
If the system status is lower than the reference value there is
no signal output.
Transmission of a 2Hz pulse in the event of a fault allows the connected
devices to monitor for line breakage.
