7 Troubleshooting
Faults reported via VLF Instant Fault Finder
This section details troubleshooting VESDAnet Interface Card problems
using the VLF Instant Fault Finder, which displays summary fault numbers on
the front panel of the VLF. There are two faults which relate to the VESDAnet
Interface Card. These faults, and actions to fix the fault, are explained below.
Fault summary 7 - Interface Card
Explanation:
• The detector is configured
for a card to be installed
but no card is installed or
the card is faulty
• The connection from card
to detector is
disconnected or the card,
cable or detector is faulty
• The firmware version on
the VLF is incompatible
with the card (e.g. the
firmware is an older
version which does not
support the card)
Action:
To see VESDAnet Interface Card LED
activity, the front cover must be removed.
1. If there is no card is present and the detector
is not supposed to have a card: Use VSC to
configure the detector for
no installed card .
2. If a card is installed: Check the ‘Power’, ‘SYS
OK’, and ‘DET’ LEDs on the VESDAnet Interface
Card.
•
If the ‘Power’ LED is not lit, check the
connection from the VLF to the VN Card. If
this connection is okay then the VN Card is
faulty and should be replaced.
• If the ‘Power’ LED is lit but the ‘SYS OK’ LED
is not flashing then the VN Card is faulty and
should be replaced.
• If ‘Power’ LED is lit and ‘SYS OK’ LED is
flashing but ‘DET’ LED is not lit, then check
the connection to the VLF. If the connection is
okay then the card, cable and/or the detector
is faulty. Replace each in turn until the fault is
resolved.
• If ‘SYS OK’ LED is flashing and ‘DET’ LED is
lit, then the VN Card is working and
communicating with the VLF but the detector
firmware version is incompatible. Use VSC
connected directly to the VLF to check the
fault number and follow the instructions in the
VSC help for resolving this issue.
