Event Log - Classe Audio CA-D200 Owner's Manual

event log Reserved for amplifiers, this feature is a protection circuitry event log which can
only be accessed when the target amplifier is in standby. The protection circuit
shuts down the amplifier or channel if it overheats or if its output could damage
your speakers. The event log details the circumstances surrounding the amp
going into protection and should be referred to in situations that require the
intervention of your dealer or Classé customer support.
The log can report the following events interpreted as follows:
• +ve slow blo trip & -ve slow blo trip — The average current has
reached the safe operating limit.
• +ve fast blo trip & -ve fast blo trip — The peak current has
reached the safe operating limit.
• over temperature trip — The unit temperature has reached the
safe operating limit.
• DC Output trip — The DC output level has reached the safe
operating limit.
• Communication failure — There has been a loss of
communication between the amp's system monitoring sensors.
• AC line trip — (Does not apply to CA-D200) The power supply
has reached the limits of the amp's safe operating range.
• Air intake filter — (Does not apply to CA-D200) The intake
filter is constricting airflow and should be cleaned. This "event"
is also triggered after every 2,000 hours of operation, even if
the sensors do not yet detect constricted airflow. The unit will
continue to operate with its standby LED flashing until the filter
is checked and the unit reset by pressing and holding the standby
button for 3 seconds.
Events are rare and generally occur due to issues that are external to the amp.
They should be interpreted positively. The amp is doing what it's designed to do.
