I changed out the board on Mp#12 as requested. Dip switch settings match and all machine functions have been checked and are working. Marty was told that he is welcome to start the press at his convenience but ghey may not have time today.

Triacs
We have several of the ITC brand temperature controllers that need new triacs for repair.
They are SanRex TG35E60.
They're about $8 each.
We have SCR's for the DME brand controllers but no triacs.
Have a great day!

Mp#1 Ejector Cylinder Leak
Mp#1 went down Thursday evening because of significant oil leaking from between the ram cylinder and the platen that the ejector cylinder is mounted to.
The mold is out now and oil has been cleaned up. I am not sure if the entire ejector block must be removed or if there is a trick to making an easier repair. When Kenny Hoskins comes in I will consult with his expertise on the matter.
I will post more soon.

Water system strainers
I went around and cleaned out the strainers. Most were not bad. About 70% had dirty water color such as this image.

Milacron 486 Valid Power issue
This is just a re-hash of the events regarding the power supply and battery issue we had with MP#5.
To summarize:
The symptoms we encountered were " Error E047" or no screen at all.
Initially, there was no screen at all. I changed the power supply with one from MRO to which it was not known to be good or bad...just another one. That brought up the E047 error.
Then upon checking power on the backplane at the test points, one of the +12 volt signals was not present.
We obtained another known to be new power supply and installed it and the +12 was then present on the backplane > however > the E047 would not clear.
We then replaced the back up lithium 3.6 volt battery and upon restarting the control, system booted as normal.
Checks of the analog circuits indicated that transducers were reading accurately at that point and we started the press for operational tests and production.
To summarize again:
1. battery must be good!
2. power supply must have all voltage signals present and testable on the backplane!

4.6.15 - Nissei control issues
MP#23-
We had a problem where somehow the upper range limit for setting the shot size got changed. We now presume that it may have been related to a low battery condition. The fix supposedly goes like this:
1. In manual operating mode > hold down the alarm reset button on the operator station (yellow).
2. While holding it down > manually retract the screw back until a prompt field appears on the controller screen. Follow its instructions.
This procedure has not been carried out as the priority of the machine has required it to run all night without interruption.
Additionally, we had an issue where one of our technicians inadvertently changed the dialog language from English over to Kanji writing. This was executed on the "shift>main data" page. Top right corner. To undo this event and return back to English, the language must be returned to bilingual or trilingual > then > go to the compile page and select English from the language field. Note: the language field may not be present initially and the process may have to be repeated with care.
The shift main data page is also where the units of measurement are located, in case someone changes from Fahrenheit to Centigrade.
For reference >According to Don Thornwald of Nissei North America, technical support:
"With barrel at oper. Temps. Hold alarm reset PB in and same time to screw backward with CS4 switch. Go back max. distance pump loading and hold there until message appears.

Release alarm PB & inject screw all the way fwd. then
check SM range.
On compile screen, left side is language selection."

Obviously I have been very busy because I haven't had time to post anything since February.
Today I wired the core switches on a mold in tooling. The cheap ejector back limit switches the molds are coming in from China with are not durable to withstand everyday use. I have been replacing them with the Omron style switches we keep in MRO, when I find them already damaged or broken. This will save $$ in both time and replacement costs, with improved reliability.
PP#1-
I added longer power cord and air hose to the pad printer. I have been doing this to all of them when they come in the shop because of the limited 230 vac receptacles we have on the IMM's and because they often need to be used out of the way from production activities at the press.
The tote system Mark is implementing for keeping up with pad printing should help to speed along changeovers when they are required, and should also provide better organization and care to the pads and cliché's over time.
Have a great day!
