As of late, milacon has been useless in troubleshooting. As it looks, I have no pilot pressure to the PV-1 solenoid. However, the pumps are functional and pilot pump is working and pushing 400 psi, directly from the pump. I am thinking there is a shuttle valve hidden inside somewhere, but cannot seem to get a sequence of the valves firing in the logic. perhaps, after the repairs to my racks, something is firing in the incorrect sequence, and it is preventing me from getting my system pressure control running.
