ERROR DETECTION

Error detection lists the individual STATE of fault indications. Errors collected are amp failure, channel failure, cable
interruption, short-circuits, load deviation, ground fault, erroneous communication via the CAN bus as well as fault
messages of other amps. A green STATE indicator signals normal operation. A red STATE indicator signals error
detection.
If one of the corresponding DETECT boxes is marked, the state of that message is additionally included in the COLLEC-
TED ERROR STATE. When activating the HOLD option, the indicator stays red after the occurrence of an error. If the
HOLD option is not active, indication returns to green, once the fault is not detected anymore. Pressing the CLEAR but-
ton in the COLLECTED ERROR STATE line resets the indicator from red to green and stored errors are deleted. The
COLLECTED ERROR STATE indicator resembles exactly the Amplifier State indicator of the System Check Window. The
collected fault state message can be outputted via a control output. For detailed explanation please refer to chapter
Config & Info.

CAUTION: Make sure to set a suitable output level, before activating
the generator. Extreme output levels can lead to permanent damage
of the connected loudspeaker systems!
Description
A red Protect indicator signals that one of the amp's internal protections has been activated
which usually results in auto-separating the power amps from the connected load via output
relays to protect the connected loudspeaker systems and the power amp from being
damaged. The Protect indicator lights for approx. 2 seconds during power-on operation.
