PLM Series Operation Manual rev 1.1.9
Displayed Text Event Log Text Category Type Description
MODULE CLIP n/a Clip Module Output clip The signal level on the outputs of
the Dolby Lake processing module
is too high and is clipping.
n/a Frame Fault: No Input
Source
Fault No input source The chosen input type has been
deselected or lost and the input
type selector has no alternative
input sources in the priority list.
n/a LoadSmart verication Event LoadSmart active LoadSmart load verication is in
progress
NO LOAD Channel Fault: No Load
Detected
Fault No load No load detected at the power
output channel.
OVER SPKR CNT Over Speaker Count Warning More Speakers A lower load impedance has been
measured than was predicted by
the Load Library for the assigned
speaker type.
PAL ACTIVE n/a Fault Power average limiter
active
Total amplier power being
delivered has exceeded the safe
maximum value and the PAL has
become active.
SERVICE CH. Channel Fault: Unit
Needs Service
Fault Needs service One or more breakers in the power
stage have blown. This is not a
user-servicable fault and the unit
should be returned to your dealer.
PSU FAULT Frame fault: PSU
undervoltage
Fault PSU fault The Power supply did not start
up properly. It could be due to
undervoltage on the mains or due
to an internal non user-serviceable
fault. If the mains are checked to
be OK and the fault persists the
unit should be returned to your
dealer.
SHORT CIRCUIT Channel Fault: Short
Circuit Protection
Fault Short circuit load The PLM is measuring both
very high load current and very
low output voltage. Short circuit
protection is active.
SPKSAFE INACT SpeakerSafe not
started
Warning SpeakerSafe inactive Warns that after LoadSmart
verication, SpeakerSafe monitor-
ing was not started.
TEMP FLT:CH Temp Fault: Amp
Channel
Fault Power channel
temperature
Temperature in the power output
stage exceeds safety limit.
TEMP FLT:DSP Temp Fault: DSP area Fault DSP compartment
temperature
The temperature of the PLM’s
processing circuitry has exceeded
its safety limit.
TEMP FLT:MAG Temp Fault: Speaker
Magnet
Fault Speaker Magnet
temperature fault
The temperature of the speaker
magnet estimated by SpeakerSafe,
has exceeded the manufacturers’
recommended maximum.
