8.3.8.3 IRIG-B (Optional Hardware necessary)
The signal generation for the output of an IRIG-B signal 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).
8.3.8.3.1 IRIG-B - Format
Following IRIG-B output formats are available:
Selection of Output Format IRIG-B / IEEE C37.118 / AFNOR
IRIG-B / B007+B127 (time, year, second of the day)
IRIG-B / B003+B123( time, second of the day)
IRIG-B / B006+B126 (time, year)
IRIG-B / B002+B122 (time)
IEEE C37.118 (previously IEEE 1344)
AFNOR NF S87-500
8.3.8.3.2 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.
8.3.8.3.3 Minimum Sync.-Status for Output
The signal output can be adjusted only to be generated when the Sync Module has reached
a minimum synchronization status. As soon as this minimum synchronization status drops
below this value during operation, the signal output stops unless the TimeOFF Timer has been
