Re: Arburg pressure issue
Find the test port and make sure you don't actually have that pressure on the pressure transducer, if you do maybe a stuck valve or a clogged orifice not letting the pressure drain back to the tank. Also check the transducer wiring, disconnect from both ends and ohm it out?
Re: Arburg pressure issue
Agree with ijchan above. Can you put an analog gage and check?
Re: Arburg pressure issue
Actually the injection unit is run by a servo, so no hydraulic to the injection unit, just the screw rotation gear box. Are you thinking a possible short in the line on the Transducer? Or should i be reading nothing when it is not running. At this point I am not sure the transducer (which is new) is accurate.
