Failure Mode - Barko 6025 Service Manual

FAILURE MODE

FAILURE MODE FAILURE MODE FAILURE MODE FAILURE MODE
The following tables contain information about the different possible failures that could occur for each module
subsystem. In most cases when an error is detected, a message will be presented on the master display together with
an error code on the module. In some cases, the module will turn off or at least shut down the outputs, to increase
safety.
