MP10- Kept going down all day with the pumps kicking off. Was getting a 5220 alarm, when indicates “Rear Door”. On this machine, “Rear Door” does not refer to the Non-Operator side door, but the doors that are to the Rear (away from injection unit) of the machine. I usually call these doors the “gates”. Anyway, Mark noticed that the non-operator side rear door limit switch needed to travel a good bit before it was made so he adjusted it.
After this, the machine still kept going down. We spent a little time troubleshooting it, but it finally got so bad it was doing it every shot they needed to run so I jumped wire #69 to #220.
This should get them running, but it needs to be removed later and the problem fixed.
It only does it when the mold is first closed, so it may be a short in a core wire or something. The only other inputs grouped with the rear doors all seem to deal with options or the cores. If something was shorted and dragging the voltage down on the entire group, this is the alarm you would likely see first because it kills the pump.
