Over Temp Indicator Led; Status Commands - Extron electronics NetPA Ultra Series User Manual

Over Temp Indicator LED

This indicator does not represent a hard failure of the unit. It is a warning the amplifier has exceeded
the recommended operating temperature for optimal product lifetime.
LED State
Problem Description
Lights steadily
Amplifier has exceeded the
recommended operating
temperature. The LED turns off
after the amplifier cools down.

Status Commands

NOTE: Status flags automatically reset when the amplifier is power cycled.
Status Possible
Triggers
53STAT:
The amplifier has
Over Temp
exceeded the
recommended
operating
temperature.
See specifications.
54STAT:
A DC signal has
DC Protection
been detected on
an amplifier channel.
55STAT:
The specified
Output Thermal
amplifier channel
limiting
has overheated
and is muting the
affected channel.
57STAT:
The current/power
Overload
limiter has been
triggered.
A short on the
affected output
channel has been
detected.
Problem Solution
Verify that the placement of the amplifier allows for suitable ventilation and airflow
Rack Mounting Ventilations Recommendations
(see
Avoid placing equipment on top or below the amplifier.
Verify that the operating temperature is within the specified range.
Possible Causes
The ambient environment
exceeds the recommended
operating temperature.
Hardware failure.
The channel is driving too low
of a speaker load impedance.
The channel is being fed
a heavily clipped/distorted
signal.
The amplifier's operating
environment exceeds the
recommended operating
temperature.
Too much current is being
drawn due to overdriving the
output.
An improper speaker load
has been attached.
The output has been shorted.

Possible Solutions
Verify that the placement of the amplifier allows for suitable
ventilation and airflow.
Avoid placing equipment on top or below the amplifier.
Verify that the operating temperature is within the specified
range.
Disconnect power then reconnect power to the unit to
determine if the unit immediately goes into standby upon
power up.
The amplifier may need to be serviced.
Make sure the correct speaker load is connected.
Check that speakers are tapped appropriately.
Recheck the amplifier's gain structure.
Verify that the amplifier's ambient environment does not
exceed the recommended operating temperature (see
53STAT
).
Recheck the amplifier's gain structure.
For low-impedance loads: Verify that total impedance at the
amplifier is ≥ 4 ohms.
For 70V/100V speaker loads: Recheck speaker taps.
Check for shorts at the output and throughout the speaker
chain.
