6.5.8 Time source
Time source configuration.
1. Type of time source: 0=none, 1=DCF low quality, 2=GPS-DCF high quality,
3=NTP, 4=AFNOR-A/C or IRIG-B 12X
2. Time zone of the source: see chapter 6.5.25 Time zone selection.
3. Alarm delay at failure of time source (minutes):
0 = off, 1-2'160min, default = 0
Error: “loss of time source TO” resp. “loss of local source”
in redundant mode as slave
4. DTS stratum: 0=Stratum is automatically calculated according to
the time source.
1-15= Stratum DTS 4138 is set by means of the
description in the table in chapter “Fehler! Verweisquelle
konnte nicht gefunden werden. Time acceptance
from an external source (DCF or GPS)”
5. Stratum limits for alarm: Limits for alarm “Time source stratum lost“ (1-16)
6. Stratum TO (Timeout):
Duration of stratum change 1 to 16 in the case of time loss (1-999h),
e.g. 24 hrs stratum counts up from 1 to 16 within 24 hrs.
Default value: 12h
7. Offset per Stratum in ms (0 – 40’000 ms). Stratum is calculated with this value
when time is received again:
Offset/Stratum = 30 ms, offset of the time source 150 ms Stratum = 5
8. Max. offset for time source to set valid time in s at start up.
(0-1’000’000s)
9. Time source correction (only for DCF), +/-60'000ms
For description of time source see chapter “8 Time administration“
