2.13.10 nights Sean

#3- press stopped about 8 0r more times with several different alarms such as injection valve off etc. Routine was powering it down then back up again. Then motor overloads began tripping about every hour. Marty stopped it because we were short a technician last night and it was becoming too much trouble.

Collin and I checked it with the ammeter , ohmed out the motor and compared it with the readings of #5. Amps were way higher and two of the legs on #3 were reading 8 ohms vs. 0.2/0.3 ohms on the other motor. Also checked the page 42 board and compared output voltages for everything and they were comparable to #5.

We suspected the motor is the cause, in addition to it tripping OL's so much lately. While inspecting the press, noticed the top oper. side tiebar bushing had came out again. I cleaned and put it back in, made a new retainer bracket for the one that was missing. Also, cleaned and lubed tiebars real well.

Put the machine into "dry cycle" without the injection unit and let it run continuous to see if there was any improvement. Has run half an hour and has not stopped, so it might be alright?? Other than changing the motor out? That is where we are with it.

Call if there are any questions.

MP20 Ejector plate bolts broke. Found one of the knock out rods threads were stripped. I fixed the knock out rod and replaced the broken bolts.

Tried to start up MP2 but couldn't put the machine in manual mode. Josh guided me through cold starting the press to get it running and said he would work on it tomorrow.

Set the welder and belt back up but they were out of y plates so they didn't run it.

The tape sensor on the heat stamp on MP20 stopped working. I adjusted on it and finally found the light/dark switch on the main panel was flipped in the wrong direction.

I was going to paint the new robot riser on MP2 but couldn't locate any brushes or rollers. Darryl and I looked in the shop, MRO, and the tech's shop but could find any.

2.8.10 nights Sean

Worked on grinders and loading system on 24. Collin said that the breaker was tripping frequently for #5 grinder. It was making a loud rumble so I pulled it apart and reset the stationary blade where it was rubbing. It has been O.K. since.



#6 robot- ran a new airline because I had already spliced the line once and it was leaking again so I put a new tubing in it. Also replaced the cabinet fan on it and checked it out for preventative maintenance.



#22 robot- painted the support column. Was going to paint the riser that Collin built but Mark talked like it was going on this morning. I can paint it after it goes on.



Need a new wire feed motor for the "Cricket" Miller wire welder in the shop. We do not need it right now but if we do in the future, it is not working.



Let me know if there are specific things you need me to start on tonight Josh. Thanks.



Call if there are any questions.

B Shift

One of the new Eagle molds with cores was put in MP17 this weekend. To the best of my knowledge, 17 has never ran cores before. Gary wired up the pull and set switches and everything worked fine. The sequence is different than the other presses. Sequence 1 is set and pull before close, 3 is set and pull after close and I'm not sure what 2 is. I'll try to put some indicator lights on the panel when it's down.

MP5 has a pre-fill valve not open in time alarm. If you probe the open side then the close side of the valve while someone is pressing clamp open it will shift and the mold will open. I checked the voltage to the valve then switched the coils out. I removed the valve and the check valve behind it cleaned and inspected them. The value seems to move smoothly. The press is still down. If number 3 is down tomorrow night I want to trade the valves out.
