Troubleshooting
The ATP senses loss of AC power or brownout conditions
affecting the amplifiers. It also provides battery backup to the
amplifiers if the audio system is active when the power failure or
brownout occurs. The ATP must have a 3-ATPINT interface Card
installed in order to work with the EST3 system.
The ATP enters a trouble state if any of the following events
occur:
• ATP brownout or loss of AC power
• Low battery charge or missing battery (with J2 enabled)
• Ground fault (if ground fault detection J1 is enabled)
• Fuse failure
