RESPONDING TO ALARMS

Exciter A/B: Exgine
Not Booted
-
This alarm occurs, in FM+HD or HD mode, when the exciter is initially
powered up, but the Exgine PWB has not finished its boot-up sequence.
Normally, the alarm will clear on its own. If not, suspect a defective Exgine
PWB.
Exciter A/B: Exgine
Offline
-
This alarm occurs, in FM+HD or HD mode, when the exciter is not
communicating with the Exgine PWB. Check the ribbon cable between the
Exgine PWB and J15 of the exciter PWB. Check the Exgine PWB.
Exciter A/B: External
Mute (Ext Mute)
-
This alarm occurs if the exciter has been muted (0 W) by the transmitter.
This is typical when the transmitter is in an ‘Rf off’ condition, or any other
condition that causes the RF drive to be inhibited (external interlock open,
etc.). If this alarm persists and there are no other causing conditions
present, check the transmitter link cable on the exciter.
Exciter A/B: External
Summary Alarm
-
Not displayed in AUI or UI status. Configurable as a remote output. This
alarms occurs if there are any external related alarms present. Check for
specific external related alarms and troubleshoot accordingly.
Exciter A/B: Fan Volts
Fail
-
This alarm is for information only and should only occur when there is no
Exciter Fan Volts present.
Inspect the LVPS-A supply and circuitry and, if
necessary, replace.
Exciter A/B: FPGA
Test Failed (FPGA Fail)
Exciter (red)
This alarm occurs if the FPGA on the main exciter card is not responding.
This alarm prevents the exciter from producing modulation or RF power, and
may be the result of a failed software upgrade or a hardware failure on the
exciter/control PWB.
Exciter A/B: In Bias
Routine (Running
Bias Routine)
Power Amplifier (red) This alarm is for information only and should only occur when the bias
routine has been initiated.
Exciter A/B: Licensing
Error
Exciter (red)
This alarm should only occur if there is a fault with the memory on the
exciter. It indicates that the exciter has not been licensed for the current
mode of operation.
Exciter A/B: Low
Battery
Exciter (amber)
This alarm occurs if the backup battery voltage falls below 2.7 V. The GV60
takes no action on this alarm. Use a digital multimeter to check the battery
voltage (with ac power on). If the battery voltage is low, replace the battery.
If the battery voltage is OK, cycle ac power (off, then on). If the alarm does
not clear, suspect the exciter/control PWB.
Exciter A/B: Missing
Preset
Exciter (red)
Visible only when replacing an exciter. This alarm occurs when there are no
presets programmed into the exciter. The transmitter should automatically
correct this.
