"That's the point. The ALC cable protects the KPA-500 when the operator 
"spaces" and leaves the exciter power control at full power (100+ Watt) level."

My experience, and I have 10 Hz logger data, shows that the amp alarms, sets 
fault FL06, and drops into standby mode with no change in the ALC voltage level 
being observed.

I didn't set out to investigate this but my logger was running when I 
accidentally tripped FL06 on 6 meters this afternoon.

It appears to me that ALC only provides protection if the normal over-drive 
protections fail.  Currently the ALC voltage only feeds my logger and is not 
connected to my TS-590S.
