[volt-nuts] Solartron 7081 randomly re-initialises

[J. L. Trantham]

David,

I have had a similar issue with mine but only on days when my stand-by generator turns on, takes the load for the house, then switches the load back to the street and shuts down.  There is clearly a brief 'power hit' when this occurs.  I've never tried to chase this down because it is relatively 'rare'.

There is a fairly 'complex' shut-down circuitry in the 7081 described in the service manual and I wonder if you have an issue there.

In any event, I suspect a 'power issue'.

Good luck.

Joe

That makes sense though +5V looked OK, I'll look a bit harder!

guestimate, executes a cold start caused by low voltage. 
so would check 5V for drops and ripple.
keep us posted on your findings
