16.1.6 Time Synchronization
Synchronization
Precision of GPS/DCF77 synchronization (not via Sync-Box):
incl. phases accuracy measuring system; typically: ±10 µs
Precision of minute pulse synchronization: ±100 ms
Precision of "Time setting" via OSCOP P:
in automatic mode, cycle time 4 hours: ±1 s
RTC drift: 30 ppm at 25 °C
Current consumption, synchronization input 7B1/7B2 at DC 24 V: DC 2 mA
Timer requirements
Precision: 5 µs
Synchronization signal level or optical output with conversion via Sync-Transceiver 7KE6000-
8AK/L: DC 24 V
Pulse width DCF77 low pulse: 100 ms ±20 ms
Pulse width DCF77 high pulse: 200 ms ±20 ms
Pulse width minute pulse: 200 ms to 1000 ms
In the event of an antenna failure, the DCF77 signal is cut off
Time basis: UTC
