The upgrade is almost finished. I found that the passive latch lock  is not closing down all the way. It has about a 3/8" gap.    See Atm. 1 & 2

The service man was here this morning and agreed to fix it.  They will be back next week. The latch needs an other spring to push it into full lock. 

We tested all possible sequences of operation of the new upgrade. It performed to specification.
