Description
The Under Voltage limiter is active as the
mains supply is approaching the lower
UVL ACTIVE
end of the device´s operational voltage.
Output power is decreased to ensure
mains distribution does not collapse
Amplifier is reducing output power due
PAL ACTIVE
to average power or mains current
draw is above safe operating levels
Power supply is reducing mains current
BEL ACTIVE
draw to stay within BEL configured
nominal current and profile
Mains glitch (missing cycles) was
MAINS GLITCH
