14.1. Faults and warnings
Category/Type Name On screen text Description Action
FRAME
Warning
Lake Controller offline CTRL OFFLINE
Frame unable to find Lake controller
on the network
Check network cabling/
network if controller
expected on the network
Warning
AES / Dante clock slipping CLOCK SLIPPING
Frame not able to lock to incoming
AES stream or Dante clock slipping.
Check AES sender and
clock configuration or
Dante clock settings
Warning
Dante device name conflict NAME CONFLICT
Two or more devices on the network
with the same Dante name
Review Dante
configuration
Warning
Dante module not detected
DANTE NEEDS
SERVICE
Lake cannot detect a functioning
Dante module
Restart device; if not
cleared it needs service
to operate Dante
Warning
Dante module with
incompatible firmware
DANTE FW INVALID
Dante module not loaded
with correct FW
Retry updating the firmware
with LakeUpdate
Warning
Dante module disabled DANTE DISABLED
Dante module not communicated
correctly or other internal
configuration fault
Restart device; if not
cleared it needs service
Warning
Sense fault DSP SENS FLT:DSP
Voltage and current sensing on amplifier
output faulty. Audio continues but
protection might be compromised.
No load monitoring
Restart device; if not
cleared it needs service
Warning
A/D converter power
supply fault
A/D PSU FAULT
Voltage supply to the analog input
converters faulty
Restart device; if not
cleared it needs service for
analog input to work
Fault
Audio Fault AUDIO FAULT
Internal audio interface
not functioning
Restart device; if not
cleared it needs service
Fault
DICO communication fault DICO COMM FAULT
Communication fault between host
and amplifier platform
Restart device; if not
cleared it needs service
TEMP
Warning
Temperature warning
power supply
TEMP WARN:PSU
Power supply temperature
approaching critical levels
Improve cooling or reduce
output power to avoid
temperature becoming
critical
Warning
Temperature warning
DSP area
TEMP WARN:DSP
DSP area temperature approaching
critical levels
Improve cooling or reduce
output power to avoid
temperature becoming
critical
Warning
Power supply
Temperature Limit
PTL ACTIVE
Amplifier is reducing output power
to avoid power supply temp
fault protection
Improve cooling or reduce
output power to avoid
limiting
Warning
Amp channel
Temperature Limit
ATL ACTIVE
Amplifier channel is reducing output
power to avoid amplifier channel
temp fault protection
Improve cooling or reduce
output power to avoid
limiting
Category/Type Name On screen text Description Action
Fault
Temperature fault
power supply
TEMP FLT:PSU
Power supply temperature reached
internal protection limit
Automatically restarts
when cooled down
Fault
Temperature fault
DSP area
TEMP FLT:DSP
DSP area reached
critical temperature
Improve cooling or
reduce power
PSU
Warning
Under Voltage Limit UVL ACTIVE
The Under Voltage limiter is active a
the mains supply is approaching
the lower end of the device’s
operational voltage. Output power
is decreased to ensure mains
distribution does not collapse
Increase mains distribution
stiffness or reduce output
power to avoid limiting
Warning
Power Average Limit PAL ACTIVE
Amplifier is reducing output power due
to average power or mains current
draw is above safe operating levels
Reduce output power
to avoid limiting
Warning
Breaker Emulation Limit BEL ACTIVE
Power supply is reducing mains current
draw to stay within BEL configured
nominal current and profile
Improve mains distribution
and update BEL
configuration or reduce
output power to avoid
limiting
Warning
Mains supply glitch MAINS GLITCH
Mains glitch (missing cycles) was
detected on the mains inlet
Check mains distribution/
connection
Fault
Need service NEED SERVICE:1–8 Power supply internal error
Restart device; if not
cleared it needs service
Fault
Mains voltage above
400 volt peak
MAINS>400 VPK
Power supply detects mains voltage
above 400 volt peak. Protective shut
down, auto restart attempt
Check mains distribution/
connection
Fault
Mains voltage above
270 V
MAINS>270 V
Power supply detects mains voltage
above operation voltage. Protective
shut down, auto restart attempt
Check mains distribution/
connection
Fault
Mains voltage below
65 V
Mains<65 V
Power supply detects mains voltage
below operation voltage. Protective
shut down, auto restart attempt
Check mains distribution/
connection
Fault
Power supply fault PSU FAULT Internal power supply fault
Check mains distribution/
connection. Restart
device; if not cleared
it needs service
Fault
Check mains CHECK MAINS
Power supply detects unstable
mains supply. Protective shut down,
auto restart attempt
Check mains distribution/
connection
Fault
Power supply power protect PSU POWER PROT
