#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.
