The Beam Off Sequence (BOFS) is the transition from any Transmit state to any Beam Off state.
It occurs so quickly that the message for this sequence may not be seen.
5.10 Fault State
The CHPA features Auto Fault Recycle mode; this feature allows the unit to return to a normal
operating state after a transient fault. When a fault occurs, the unit enters the Fault state. After a
brief interval, the unit tries to return to the previous state. If three faults occur within a 20-
second period, the unit latches in the Fault state. Once the unit is latched in the Fault state, clear
the fault source and then press the CANCEL button to return to the Standby state.
If fewer than 3 faults occur within 20 sec, the unit recycles to the previous operating state. The
RECYCLED FAULT LED will continue to flash when the unit sucessfully recycles from a fault.
Press CANCEL to stop this LED from flashing.
