ALL TEMP FLT:PSU Temp Fault: Power Supply Unit Fault The temperature of the PLM’s PSU has
exceeded its safety limit.
ALL TEMP FLT:VC Temp Fault: Speaker Voice Coil Fault The temperature of the speaker voice
coil (estimated by SpeakerSafe) has
exceeded the manufacturers’ recom-
mended maximum.
ALL TEMP WARN:
PSU Temp warning: Power Supply
Unit Warning High temperature in the Power Supply
Unit.
ALL TEMP WARN:CH Temp Warning: Amp Channel Warning High temperature in the power output
stage.
ALL TEMP
WARN:MAG Temp Warning: Speaker
Magnet Warning The temperature of the speaker magnet
is high (estimated by SpeakerSafe).
ALL TEMP WARN:VC Temp Warning: Speaker
Voice-Coil Warning The temperature of the speaker voice
coil is high (estimated by SpeakerSafe).
ALL UNCERTAIN
LOAD Uncertain About Load Type Warning When speaker Fingerprints are taken a
tolerance band is also defined 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.
ALL UNDER SPKR
CNT Under Speaker Count Warning A higher load impedance has been
measured than was predicted by the
Load Library for the assigned speaker
type.
20000Q UVL ACTIVE N/A Warning The Under Voltage limiter is active as the
mains supply has fallen between 65 and
80 Volts. Output power is descreased to
ensure mains distribution does not sag.
ALL VHF FAULT Channel Fault: Very High
Frequency Fault An exceptionally high level of continuous
HF has been detected at the PLM’s
power output stage.
ALL VOLTAGE CLIP n/a Fault The peak voltage at the output terminals
has exceeded the user-defined safe
maximum.
ALL WRONG LOAD Load Type / Routing Mismatch Fault LoadSmart is measuring load charac-
teristics which differ from those of the
assigned speaker type.
