Page 12: Section 3: Operation
SECTION 3: OPERATION DEFINITIONS ACTIVE ALARMS An active alarm is a Redundant Amplifier Unit (RAU) generated fault, which indicates that the unit is presently detecting a fault. The active alarms that can be reported are: • An amplifier alarm is active while the current drawn by the amplifier exceeds the current limits programmed into the unit for that amplifier. -
Page 13: Operating Modes
OPERATING MODES The operating modes of the RAU are selected from the front panel (in Local mode) or over the remote bus (in Remote mode). AUTO MODE In Auto mode the On-Line/Standby status of the amplifiers is controlled automatically without operator intervention. Amplifier path control is locked out from both the front panel and the remote bus. -
Page 14: Front Panel
locked out. The event log and any active alarms can be examined while the unit is in REMOTE mode. FRONT PANEL The front panel has been organized so that important information is available at a glance. Control functions and additional status information is available through a menu system and the front panel LCD. -
