Hello Fellow MAPP Members!
We are in a rural setting and we will sometimes experience unexpected power outages.  This will cause presses to power off while having material in the barrel.  We have decided that we need to make a procedure for the restarting of equipment once the power is restored.  I thought before we started to craft one that we would put a thread on the forum to see if any members had one they would be willing to share with us.

Thanks in advance!!

Treat as a Monday Morning/post holiday start-up, except there is no purging compound in the barrels.
After temps are reached, purge out heat sensitive resins right after cold start ends. For filled resins, retract screw a bit before rotation, after cold start delay ends and purge out resin. Don't begin rotation in any case in a "nest" of resin that has sat in barrel, especially filled resins.
Also; all your motor driven equipment, especially presses,"thermolaters", and chillers should be manually shut down so that when power returns,they don't try to start themselves missing phases.
