AUTOMATIC RECYCLE
The feature automatically recycles the TWTA ready to "RF on" in
the event of a momentary fault condition, such as power outage of
less than 3 seconds, low line voltage, over-temperature, or helix
current overload. In the event of two consecutive helix current
overload faults, the TWTA will revert to the "off" mode and require
manual reset (either locally or via the remote interface) or recycling
the prime power.
