5.4.6 Loadsmart results
The Load Results page reports the findings of the
verification procedure and and also contains the
function controls for SpeakerSafe. Results for each
of the PLM power outputs are displayed together
with a summary in the ‘All’ column.
5.4.6.1 Load Type verification
The results shown in the Load type row of the table
will be one of the following:
Correct
▸
– The measured load characteristics
closely match the values predicted from the
load library data in combination with the total
resistance calculation. The load is assumed to
be of the correct type.
Uncertain
▸
– The measured load characteristics
exhibit a degree of variance from the predicted
values. A warning will become active on the
channel.
Wrong
▸
– The measured characteristics differ
widely from the predicted values; it is assumed
that the load has malfunctioned or is of the wrong
type. A Fault is issued and the channel remains
muted. A successful re verification or a power
cycle will clear the fault and the mute state.
No model
▸
– Fingerprint data is missing from the
Module file selected.
aborted
▸
– A power output channel was in a
protective state during the load verification
process (e.g. temperature fault).
The All column summarizes the result of the
Number of Cabinets verification. It
summarizes the result from each power
output channel in the order Verified/Wrong.
For example 2/1 mans that two channels were found
to have the same number of cabinets as configured
and one did not.
If the Load Type verification fails, the power
output channel will be muted to prevent
damaging the speaker. A subsequent Correct
or Uncertain verification, or a power cycle
of the unit, will resolve the muted state.
5.4.6.2 Cabinet Count Verification
The results in the Number of cabinets table row
will be one of the following:
Verified
▸
– The measured load impedance
indicates that the number of cabinets connected
to this power output matches that configured.
Wrong
▸
– The measured load impedance indicates
either that the number of cabinets connected to
this power output channel is incorrect.
If the correct number of cabinets were
entered but the results returned are wrong
then it is still possible to force the settings
