Troubleshooting Wideband Radio Head
4-8 044-05251 Rev A
Remarks:
The Door open alarm requires an optional door switch described in the P33 Alarm Port section in
Chapter 5.
The Main power breakdown alarm requires a relay not included in the WRH (see Main Power
Breakdown Relay in Chapter 3).
110 SW
incom-
patibility
MRX Error The MRX and CU software is not compatible.
Suggested remedy: Check the software versions and
replace the incompatible one.
120 Startup
error
BSA # Error A hardware error is detected on the BSA PCBA at
powering up.
121 Synthe-
sizer fault
BSA # Error Unlocked synthesizer.
The frequency synthesizer is unlocked and the trans-
mission can take place on an unknown frequency.
122 Volt Reg
fault
BSA # Error A DC voltage to an analog part of the PCBA is miss-
ing.
123 PA fault BSA # Error Low power amplifier gain.
The PA PCBA has too low output power for the RSSI
and gain set. Not available in all CU software ver-
sions.
124 Param R/
W fault
BSA # Error EEPROM read or write failure on the BSA PCBA.
125 High tem-
perature
BSA #
Warning The BSA PCBA temperature is higher than 85°C.
Error The BSA PCBA temperature is higher than 95°C and
the power is turned off.
Ceasing The temperature has fallen to below 70°C and the
power is turned on again.
126 High PSU
voltage
BSA # Critical The PA supply voltage is too high.
Suggested remedy: Ensure that correct PSU is used.
127 Unsup-
ported
PA- type
BSA # Error The ID of the mounted PA PCBA is not expected by
the BSA PCBA. Suggested remedy: Ensure that cor-
rect PA PCBA is used.
128 BA HW
alarm
BA # Error A HW error on the BA PCBA has been detected.
Ceasing The BA PCBA is working properly after failure.
129 PA Under-
voltage
alarm
PA/BA # Error PA voltage level below alarm limit. Suggested rem-
edy: Check the PSU.
Ceasing The cause of the alarm has ceased.
BSC,
UL/DL
Error PA voltage level below alarm limit. Suggested rem-
edy: Check the PSU.
Ceasing The cause of the alarm has ceased.
245 Not In
Allowed
Area
CU None WRH is moved from the operating area and the RF
HW is switched on or off.
