Overview Hardware Errors
•
Adjustment of internal quartz frequency error
Problems with the internal quartz regulation of the Sync Source (here Module
8024GPS) have occurred. So the specified accuracy of the Sync Source cannot be
guaranteed anymore.
•
Antenna circuit shorted
The Sync Source (here Module 8024GPS) has detected a short circuit in the antenna
system. The antenna system should be checked.
The error can be suppressed if e.g. an amplifier with its own power supply is used.
•
Antenna circuit open
The Sync Source (here Module 8024GPS) has detected an open antenna input. The
antenna system should be checked.
•
FRAM error
If this error occurs even after a voltage reset, the support team of company
hopf
needs to be contacted for further actions.
•
RTC error
If this error occurs when time is configured or synchronized (synchronization status is
not INVA) and and even after a reset of the Sync Source (here Module 8024GPS) the
internal backup clock may be defective.
•
GPS receiver communication error
If this error occurs even after a Power-Reset, the support team of company
hopf
needs to be contacted for further actions.
•
GPS receiver in raw data mode
– no synchronization
If this condition is indicated, the GPS receiver requires special data from the GPS
signal for which it needs up to 13 minutes signal reception of satellites. Only then the
Sync Source (here Module 8024GPS) can be synchronized.
This happens e.g. after resetting the Sync Source parameters to factory default
values.
