Model Displayed Text Event Log Text Category Description

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 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.

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-dened 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.
