Operational Errors

During normal operation if a fault occurs one of the following error messages will
be displayed.
If the cooling fans stop working during operation this error
message will be displayed for about 3 seconds along with an
audible alarm (5 short tones). The Alarm indication LED
will illuminate and remain on. The BLA600 will continue to
function, as all of the other safety measures are still protecting
the amplifier, however we recommend that the cause of the
problem be investigated before further use. The cooling system
is an essential system for the correct function of the amplifier
and further damage may occur if ignored.
Indicates that the power supply has overheated. (>62°C). The
error message will alert the user and there will also be an audible
alarm of 5 short tones. The Alarm indication LED
illuminate. The amplifier will not be operational until the
temperature has fallen to an acceptable level, at which point the
amplifier will reset. If this occurs possible causes are the cooling
fans are not working, The inlet / exhaust for the cooling fans is
obscured or the amplifier is being used in an excessively hot
ambient temperature, or the amplifier has been in transmission
for an excessively long period of time
This indicates that the Heatsink temperature has reached 70°C.
The amplifier will sound 5 short audible tones and the Alarm
b
LED will illuminate. The BLA600 will remain inoperable
until the temperature has reduced to 62°C at which point it will
automatically reset.
