Changed out a loader motor for Cory that was taggedcbad since March 2013. It was the last one in MRO.
Mp#12- hooked up the air poppet solenoid for the gates. Had to add fittings for tubing.
Wired solenoid for:
252- injection signal
67- 24 vdc
Roy changed out nozzle band heater on Mp#25.
Mp#- 1- ran great all night, robot had no issues. Great work Kenny Hoskins!
Found that the mold was watered incorrectly. It was an honest mistake though because of the way that the rotary coupling joins up supply circuits internally.
After getting the mold plumbing straight, it chilled down to 62 before I shut off the cooling water.
See images for details.
Roy Smith and Mike Sells finished making the modifications to the conveyor.
I shortened the wotk station six inches and moved it to the staging area.
I also changed out five heaters in one of the dryers and it is ready to check operation.
We worked 4 hours.
Problem originated from day shift. The grinder would start and run until parts were put into it. After which contactor would begin to chatter (such as coil dropping out). Normally the most frequent problem with these grinders can be traced to the safety circuit switches. In this case I could find nothing wrong with any of the control components. After watching it in operation. ..I discovered one of the control fuses off the transformer was arcing and incorrectly mounted to where it was just barely making contact. I checked the fuse and found it to have changed resistance value. I replaced it and made sure the others were installed correctly. No further problems.
Mp#13-Fuse blown control issue.
This problem originated from day shift where the power supply had a fuse holder melted.
There was an additional 10amp fuse blown with a fault indicating that the purge sheild LS99 was not made.
Upon replacing the fuse everything seemed fine until the pump motor was started.
After a few minutes of pump run time the fuse would blow again. Reviewing the schematics revealed the "CE" solenoid is energized through a motor starter contact.
Found "CE" solenoid was bad. Replaced it with spare from uninventoried parts. O.K. to run.
The sled cylinder shaft seal needs replaced on Mp#27. It was found leaking oil in the floor. I cleaned up the oil and put an absorbant pad under the leak. Maybe Kenny knows if we have another seal or where we can get one?
Please add to the list!
