GV30N TROUBLESHOOTING MANUAL
RESPONDING TO ALARMS
VERSION 0.1 2014-11-01
PAGE 4.1.23
Exciter A/B: Unsigned
FPGA Image (Bad
FPGA Image)
Exciter (red)
This alarm indicates that the exciter is operating with ‘unsigned code’, but
is otherwise operational. This alarm may only be displayed if the transmitter
is operating with a ‘beta’ version of factory software.
Exciter A/B:
Unsupported Audio
Configuration
Exciter (red)
This alarm indicates that the user has selected a preset configuration for the
audio processing in the exciter that cannot be implemented. This may be
due to attempting to use the same physical input for multiple purposes, or
because two incompatible modes have been selected.
Exciter A/B: +15V
Fail, -15V Fail
Power Supply (red)
This alarm occurs if the +15 V or -15 V power supply in the controller is 2 V
higher or 2 V lower than the desired value.
Exciter A/B: +5V A or
B Fail, +3.3V Fail,
+1.8V Fail, +1.2V Fail
Power Supply (red)
This alarm occurs if the associated power supply in the exciter is 10%
higher or 10% lower than the desired value.
Module #: Fan 1-6 Fail Power Amplifier
(amber)
This alarm occurs if the module fans have been enabled, but the fan
tachometer measurement is below 2200 RPM. Inspect the affected fan and,
if necessary, replace it (see
“Module Cooling Fan Replacement” on
).
Module #: Fan Fail
Shutdown
Power Amplifier (red) This alarm occurs when more than one of the module’s six fans have failed.
The module will shut down. Failed fans must be repaired or replaced before
the module can operate. Check for associated Fan 1-6 Fail alarms and
troubleshoot accordingly.
Module #: Fan Volts
Fail (Fan V Fail)
Power Supply (red)
This alarm occurs if the associated module’s cooling fan supply voltage is
10% high or 10% low. This may be the result of a circuit fault on the
module control/interface PWB.
Module #: High Reject
Power (High Rej)
Power Amplifier (red) This alarm occurs if the associated module’s reject load power exceeds
400 W. This may be the result of PA failures. Check for associated alarms
and troubleshoot accordingly. This alarm may be accompanied by a Reject
Foldback alarm, which means the transmitter power will be reduced to
protect the reject load.
Module #: High RF
Drive Power (RF Drv
High)
Power Amplifier (red) This alarm is indication only and occurs if the input RF drive (exciter power)
is greater than 45 W. Check the exciter power setpoint to make sure it is
correct for the transmitter.
Module #: High
Temperature (High
Temp)
Power Amplifier (red) This alarm occurs if the associated module’s heatsink temperature exceeds
85°C (185°F). This alarm is most likely caused by excessive ambient
temperature, a module fan failure or blockage, or excessive power amplifier
dissipation. This alarm will clear when the module’s heatsink temperature
decreases to 75°C (167°F).
