I've seen the timers: heartbeat.conf has two 300 sec timers, upssched.cmd looks 
like what is often called upssched.conf and has a 660 sec timer.  So it looks as 
if the heartbeat has worked once, after 10 min.

Do you have a file upssched.conf?

I would expect upssched.cmd (perhaps upssched-cmd) to contain a script.
