3.6.4.3.2 Timebase
– Timebase of the output IRIG-B Signal
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.
3.6.4.3.3 Minimum Sync.-Status - Status-Dependent Pulse Output
The signal output can be adjusted only to be generated when the Sync Module 8024GPS 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 set greater than 0. In this case the output is done for the duration of the TimeOFF
Timer despite the minimum synchronization status for the output falls below the set value.
Range of Sync.-Status
The synchronization status is represented from the bottom of the following table (INVA) up
with increasing quality.
Synchronisation Status
SYNC
Time synchr quartz control started/running
SYOF
Time synchr SyncOFF running
SYSI
Time synchronized as simulation mode
(with no actual GPS reception)
QUON
Quartz/crystal time + SyncON running
QUEX
Quartz/crystal time (in freewheel after synchronization
failure
Board was already synchronized)
QUSE
Quartz/crystal time after reset or manually set
INVA
Invalid time
Value range TimeOFF timer = 0 to 65635min.
3.6.4.3.4 Status of the Signal Output
The status of the output is stated via a display element with the following color and text
indications:
GREEN
OUTPUT active
There is a signal output
YELLOW
OUTPUT
+ TimeOFF active
There is a signal output
for the duration of the TimeOFF Timer
RED
OUTPUT blocked
There is
no
signal output
