8.6 DGW-FF Troubleshooting
LEDs
312 Segment / spur voltage is
too high
Fieldbus power supply
failed
Check and replace fieldbus
power supply
Device coupler failed Check device couplers and
device coupler terminals
313 Segment / spur voltage is
too high compared to com -
missioning
Fieldbus power supply
replaced with incompatible
model
Install correct fieldbus
power supply
Fieldbus power supply
failed
Check and replace fieldbus
power supply
This is possibly a result of
other errors
Solve other reported errors
first and check segment
again
Device coupler failed Check device couplers and
device coupler terminals
314 Segment / spur voltage is
too high
Device coupler failed Check device couplers and
device coupler terminals
Fieldbus power supply
failed
Check and replace fieldbus
power supply
315 FDH-1 appears to be con -
nected to a spur
The signal level of one
device is too high
If FDH-1 is not connected
to a spur, re-check with a
specific segment record
316 Jitter is "Out of specifica -
tion" and the signal level of
devices is too high for the
given topology
Not enough terminators Check if a terminator is
installed on both ends of
the trunk
317 Jitter is Good and the sig -
nal level of devices is too
high for the given topology
Not enough terminators Check if a terminator is
installed on both ends of
the trunk
318 Jitter is "Good" and the sig -
nal level of devices is too
high for the given topology
Not enough terminators Check if a terminator is
installed on both ends of
the trunk
319 Jitter is "Out of specifica -
tion" and devices signal
level is too high for the
given topology
Not enough terminators Check if a terminator is
installed on both ends of
the trunk
320 Segment voltage too high
for the given topology
Wrong fieldbus power sup -
ply installed or wrong topol -
ogy configured
Replace fieldbus power
supply or correct topology
settings
ID Phenomenon Cause(s) Action(s)
Behavior Cause Action
Green PWR is OFF No power supply Check power supply and wiring
Red ERR is ON Hardware failure detected Send device to manufacturer
Red ERR flashes ADM address conflict Check for ADMs that have the
same addresses, one connected
to CH1 other to CH2
Yellow Link/Act
flashes
Ethernet communication is active No error
Yellow CH1 is OFF
(FF Mode)
No ADMs detected on channel Check wiring. Are there ADMs
supposed to be connected to the
channel?
