York Style B Liquid cooled starter

[toptech]

This one is for RichL and anyone else for that matter,
I have a York starter that is generating the fault
High temp on phase b.
I changed the coolant, (brown and yucky)
ran new coolant for aboot 30 min and flushed.
then added new coolant again. After 1 hour run time each phase was at 109F.
After I left it generated the fault and shut her down.
Any thoughts?
I have not been back to ohm any thing out yet

had the same problem on a york 123 millenium with touch display.if you have the same one set up a trend to monitor the heatsink temps.btw mine was the sensor going bad.replaced it and haven't had any trouble since

Strainer?

Have you punched the tube on the htex? They always seem to get missed.

I had a machine with liquid cooled SCR Starters. The heat exchangers were completely clog up with brown gunk no water(at the time) could pass through it. The exchangers have ports that were drilled to allow liquid to flow through. The ports were sealed with a screw plug. The high temperatures from it being clogged up caused the water to leak around the plugs. Boom!! A direct short to ground. I replaced all three SCR exchangers, reran the coolant lines, then added York's new purple nonconductive coolant.

toptech;
I would respectfully suggest that you connect a printer to this puppy and print out the history on it..Mainly to find out if chiller was even running when unit tripped on Hi-Temp.

I would bet a dollar to a hole in a dough-nut that the chiller was not even running when the "Hi-Temp" failure occured..
Should the chiller shut down under load and the condenser water pump not continue to run, the residual heat in the bricks is more than enough to cause the Hi-Temp trip..

Should that "Not" be the case, I would surely add a couple of "Ferrite Beads", (Snap on magnet thingy's available from Radio-Shack) around the multi conductor cable @ the SSS board connector that goes to the board inside the control panel.

This is a common occurence whenever someone has installed a condenser flow switch and for whatever reason it trips. It is not remembered as a "Chiller Failure" and therefore not shown on display should the unit then trip on "Hi-Temp"..After stewing on a loss of condenser water.

If a condenser flow switch is installed...take it out of the circuit..you do not need it...Or want it..for obvious reasons..

Lastly, make certain that No attempt at the "Modulating" of condenser water flow is being done. The Lil' heat exchanger needs all the water it was made for.

But then....TJMHO

I plan on being there, I need to change my tag line. :)

Sorry it took so long to respond,
I do appreciate the input but am sorry to report that I got the info second hand and reported the wrong error.
The actual error is shorted SCR on phase B.
Our tech Followed the procedure outlined in the starter check out manual.
He stated that the SCR were all in range of specified values.
The error could not be cleared and the chiller is still down.
You can horse whip me later for posting the wrong info!!
Thanks again
Bernie

Just wondering?

Well today is the day,
I have to go in @ 3am to trouble shoot this problem.
If any one can post to my revised delima today I'd appreciate it!!

Also I have another question for you guys,
What type of printer is required?
Is it infared?
