2.9 Error Messages
The 7001RC system monitors itself and the installed system bus function boards for any
errors. The synchronisation status of the sync. sources and the system bus itself are also
monitored. In the event that any sync. source is lost the corresponding error bits are set in
the error byte. In this way it is possible to differentiate between errors in the individual
synchronisation channels:
ERROR-1 GPS
ERROR
0 / 1
Bit 1 changes from
"0"
to
"1"
when the system in
GPS mode
(Synchronisation
Channel 1)
is set as sync. source for the system but has no GPS reception.
ERROR-2 DCF77 pulse - ERROR
0 / 1
Bit 2 changes from
"0"
to
"1"
when the system in
DCF77 pulse mode
(Synchronisation Channel 2)
is set as sync. source for the system but is not receiving
DCF77 pulses or they are faulty.
ERROR-4 Master/Slave-String - ERROR (failure)
0 / 1
Bit 4 changes from
"0"
to
"1"
when the system in
Master/Slave-String mode
(Synchronisation Channel 3)
is set as sync. source for the system but the
Master/Slave-String was read incorrectly or is not available.
ERROR-5 Master/Slave-String - ERROR (quartz only)
0 / 1
Bit 5 changes from
"0"
to
"1"
when the system in
Master/Slave-String mode
(Synchronisation Channel 3)
is set as sync. source for the system but the serial
Master/Slave-String reports "Quartz operation".
ERROR-9 System Synchronisations Status - ERROR
0 / 1
Bit 9 changes from logic
"0"
to logic
"1"
when the
System Synchronisation Status
is
not radio synchronous.
The options available for evaluating error bits are described in detail in the 7001RC system
specification.
The non active sync. mode is not error controlled.
