Troubleshooting Wideband Radio Head
4-2 044-05251 Rev A
Ceasing PSU2 in the cover works properly again. Ceasing is sent if the
PSU2 works at start-up, and there is a corresponding critical
PSU2 alarm logged in the Events Log. The WRH will restart
when the power is back and this alarm will be sent.
FON Error The FON 10 Volt charger voltage is below limit. Suggested rem-
edy: Replace the FON
Ceasing The cause of the alarm has ceased.
2 WRH
restart
CU None Power on start, or user ordered reboot. Logged to indicate a nor-
mal power up, or a restart ordered by the operator.
Warning Software error restart, 1st – 7th time. Restart 1st to 7th time dur-
ing a 14 day period. The counter is reset every 14th day, counted
from power up.
Error Software error restart 8th – 10th time. Restart 8th to 10th time
during the 14 day period. At the 11th time, the SW bank will be
blocked and not used anymore until a user ordered reset is per-
formed, or power is switched off/on.
3Mains
break-
down
External Critical The mains power is gone. Used with an external relay indicating
mains breakdown. The external relay should be connected to
External Alarm 1 and the WRH configured to indicate this alarm.
If no relay is used, a mains breakdown will be reported as a PSU
fault.
Ceasing The mains power is back. Sent if there is a corresponding critical
mains breakdown alarm logged in the Events Log. The WRH will
restart when the power is back.
4Alarm
reset
CU None Alarm reset by the user. All alarms are reset. The cause of the
alarm will be re-evaluated and reported, if still active.
5 Local bus
error
WBA #,
PA#,
MCPA#
Error Error when communicating on the bus. The CU has no contact
with the WBA, PA or MCPA PCBA, which is taken out of service.
6 Main bkd
w backup
External Error Used to indicate that the mains is no longer available. WRH is
powered by external battery backup unit.
Suggested remedy: Check the mains power.
Ceasing The cause of the alarm has ceased.
7 Err in AD-
converter
Warning The analog-to-digital converter on the CU PCBA does not give
reliable values.
8 New unit
detected
None Compared to the last power on, the CU has recognized at least
one additional hardware unit.
9 Inst. unit
lost
Error Compared to the last power on, the CU lacks at least one hard-
ware unit.
10 EEPROM
error
CU Error EEP read or write fail. Data cannot be written or read from the
EEPROM on the CU PCBA. User parameters are stored in the
EEPROM.
11 Log mem-
ory fault
Error Log memory fault. Indicates that the log memory on the CU
PCBA is faulty. The WRH will not work. Not available in all CU
software versions.
12 High temp CU Warning The CU PCBA temperature is higher than 90°C.
