If the filler was slowed down to allow the packer to catch up, wait
until the holding area is approximately 1/3 full before allowing the
filler to run at full speed again.

Rung 2:6
If the high-speed counter reached its high preset of 350 (indicates
that the holding area reached maximum capacity), it would energize
O:0/0, shutting down the filling operation. Before re-starting the
filler, allow the packer to empty the holding area until it is about
1/3 full.
