Mostly cleaned up in the shop and helped the process tech do a mold change etc.
Worked on the dryer in the shop, found a loose wire connection on a relay block terminal.
There is an oil line leaking on #11 (ejectors) but it was running and they did not want to stop production.
I talked to Mark last night and he is going to call me when the pump for #5 comes in on Monday so I can come in early and we can both work on it.
I wish all of our team a very Happy Holiday!

Worked on Star Robot on MP24. Display was dead on power up. Disconnected all I/O connectors on the main power board with the power off, powered up controller, and the pendant came back to life with errors. Started plugging in connectors one at a time with the power on and CNA made the pendant lose power. Looking at the prints, connector CNA has limit switches that are around the EOAT, on inspection of this area I found that a cable labeled LS4 that had bare wires that had got together. I insulated the wires from each other and everything powered up no problem. I was able to move the robot around and send it home. So evidently a short with the 24VDC will not allow the system to power up.
Changed over the Z axis encoder on MP5 to a BEI encoder. On power up the robot could not find itself, so I swapped the A+ and A- with the B+ and B- channels. On power up this time, the robot referenced fine and homed itself. There is a box on my desk with (1) new BEI encoder, connectors, pins and sockets, and a print. Since we are out of the old encoder again, we should start changing over to the new encoder on a failure. We only have (1) new encoder right now but more are on the way.
I replaced, dated the PCB backup battery in MP25. It has an NC9000G controller and only has (1) back up battery. They are supposed to be good for 5yrs.
I replaced, dated the PCB backup batteries in MP22. It has (2) batteries like MP24, (1) on the back panel and (1) under a cover on the back side of the main cabinet door.
Called Milacron to track the pump for MP5. They said it didn’t go out till today and wouldn’t be here until Monday, the 28th. I feel goobed.
I believe I heard that new GO switches are here and are in MRO, I think several have been robbed.
That is all I have for today, have a very Merry Christmas and we will see you next week.

I took the inverter out of #22 robot the other night because it kept tripping the breaker. It had a bad 3-phase full bridge rectifier and I found one online for $34. Mark ordered it and I put it in and tested it out and everything seems fine. They haven't ran the press so I'm not sure what program is in it.
The insert press on MP10 quit working. I found a loose bolt that the sensor has to see in order to start.
The z-axis encoder went out on MP4 robot and I think we are out of them. I switched it with the MP5 since it's waiting on a pump.
The robot on MP24 will not power up the pendant. I tried the pendant from 25 but no luck. The control board does have power but the board's lights will not come on. I planned to switch boards with another similar robot but none were down.

MP#17-refilled with Hydraulic oil. It had ran a little low and would not lockover.
Sped up the flow controls (at Marty's request) to the ultrasonic welder on Press#4- because the operator could not keep up with the machine due to having to wipe color from the parts. I adjusted down speed of press head and operator door speed.
Remade an broken bracket for the connector press on #10.
Also helped the technicians set-ups some of the star robots to pack parts on belt better, and hook up regrind onto the matsui dryers,etc.
Cleaned up in the shop, especially around the welding area.
As far as #22, and #24 robots...I don't know what is going on with them, no info?
Call me if needed, I will be glad to come in and help with anything. See ya Wednesday evening at 6p.m.

MP-6 Added oil to tank.
MP-4 Had to adjust core 1 pull switches. The core 2 cylinders were leaking; tightened them, but couldn’t get the top one to stop leaking, so I
just put one of the sensors in to plug it.
I emptied the waste oil vac.
MP-8 I made & installed leg pins for the robot cage.
Dryer - D 24 - They were having trouble with this one last week. Breland was using it to dry polycarb @ 250 degrees. This dryer is one of the older CS101’s
& it struggles to run at that temp. It works great up to 200 degrees so I put a label on it --- set point not to exceed 200 degrees . If they
don’t like it , they can purchase an after cooler for it.
