VS1 Troubleshooting Manual Responding to alarms
Issue 10.0 2018-10-29 Page 1-17
Host Network
Down
Exciter (amber) This alarm indicates that the microcontroller that runs the remote
interfacing applications is unable to acquire an IP address. When
this alarm is present, the communication between the LAN
controller (server) and the transmitter server that was once
established has now been lost. It will not be possible to access
any of the remote AUI functionality. Check that the Ethernet cable
is properly connected to A1J8A (LAN) on the rear of the
transmitter. If the alarm is still present see “Network Setup” on
page 2-127 of the Operations and Maintenance Manual for
information on setting up the network connection. Disable the
alarm by setting DHCP to OFF and setting the IP Address to all
zeroes (i.e. 0.0.0.0).
Host Not
Booted
Exciter (amber) This alarm indicates that the controller’s host has not finished
booting. The remote AUI will not yet be available. Occurrence of
this alarm is normal for approximately one to five minutes while
the host is booting, immediately after ac power has been applied/
restored or after a software upgrade. If this alarm continues to
occur more than 30 minutes after ac power has been applied to
the transmitter, cycle (turn off, then on) the ac power. If the alarm
persists after 30 minutes, replace the exciter/control PWB (A1)
(see “Exciter/Control PWB Replacement” on page 1-43 ).
Host Not
Responding
Exciter (amber) This alarm indicates that the microcontroller (host) that runs the
remote interfacing applications is not communicating with the
transmitter’s primary microcontroller (DSP). If the watchdog
function is enabled, the DSP will automatically reset the host. If
this alarm persists for more than 10 minutes, try cycling power
(off, then on) to the transmitter. If the alarm persists, replace the
exciter/control PWB (A1) if necessary (see “Exciter/Control PWB
Replacement” on page 1-43 ).
Insufficient
Fans Active
(Insuf. Fans
Active)
Output Network
(red)
This alarm indicates that the fans in the transmitter’s RF power
stage are not running. This alarm causes the transmitter to shut
down, and clears when the system detects a running fan in the RF
power stage. See
Fan Fail
alarm for troubleshooting information.
Invalid HD
Data
- This alarms occurs, in FM+HD or HD mode, if IBOC data is
detected from the Exgine PWB, but is not usable (all logic 0s).
Digital carriers are muted. Check the IBOC data source.
IPA Fail PA (red) This alarm occurs if the
IPA Output Low
alarm is present and the
measured IPA current is below 225 mA. The VS1 takes no action
on this alarm . See
IPA Output Low
for troubleshooting tips.
