TEMP FLT:PSU Temp Fault: Power
Supply Unit
Fault Power supply
temperature
The temperature of the PLM’s PSU
has exceeded its safety limit.
TEMP FLT:VC Temp Fault: Speaker
Voice Coil
Fault Speaker Voice Coil
temperature fault
The temperature of the speaker
voice coil (estimated by Speaker-
Safe) has exceeded the manufac-
turers’ recommended maximum.
TEMP WARN:CH Temp.Warning;
Channel
Warning Power output
temperature warning
High temperature in the power
output stage.
TEMP
WARN:MAG
Temp.Warning;
Speaker Magnet
Warning Speaker magnet
temperature
The temperature of the speaker
magnet is high (estimated by
SpeakerSafe).
TEMP WARN:VC Temp.Warning;
Speaker Voice-Coil
Warning Speaker voice coil
temperature
The temperature of the speaker
voice coil is high (estimated by
SpeakerSafe).
UNCERTAIN
LOAD
Uncertain About Load
Type
Warning Load uncertainty When speaker Fingerprints are
taken a tolerance band is also
dened to take into account
production variations. If LoadSmart
results lie in this band a Load
uncertainty warning results. The
user should re-check the load and
if all appears to be correct it is likely
that normal operation will result.
UNDER SPKR
CNT
Under Speaker Count Warning Fewer Speakers A higher load impedance has been
measured than was predicted by
the Load Library for the assigned
speaker type.
VHF FAULT Channel Fault: Very
High Frequency
Fault VHF at output An exceptionally high level of
continuous HF has been detected
at the PLM’s power output stage.
VOLTAGE CLIP n/a Fault Voltage limiter active The peak voltage at the output
terminals has exceeded the
user-dened safe maximum.
WRONG LOAD Load Type / Routing
Mismatch
Fault Load type mismatch LoadSmart is measuring load
characteristics which differ from
those of the assigned speaker type.
