Hi every one, Was wondering if someone has info on the failed item I got on the scanner while performing loop calc.

          V=5 R=0 F=18 Pin 51 (K51 and K115) Ch. A MaxDif=90 Tol=6
Failed ***

I purchased the CD manual, don't know if the info is there or not. but the CD been misplaced and cannot find it. 


          V=5 R=0 F=18 Test Pin 51 (K51) Ch. B MaxDif=1 Tol=5
Passed
          V=5 R=0 F=18 Pin 51 (K51 and K115) Ch. A MaxDif=90 Tol=6
Failed ***
          V=5 R=0 F=18 Pin 51 (K51 and K115) Ch. B MaxDif=5 Tol=6
Passed
          V=5 R=0 F=18 Common Pin 51 (K115) Ch. A MaxDif=1 Tol=5
Passed

Hi
What results do you get on the other Diagnostics tests?
Have you checked the various supplies on your ProTrack?
There are some isolated supplies for the Scanner.
I found out about these when I accidently connected a 12 V.D.C. PSU to my Scanner.
It blew up a few components as described on this Forum.
The Scanner prefers a 5 V.D.C. PSU.

I read your post about the scanner and 12 volt power supply. That's one of the reasons I'm careful now, thank you.
The protrack by itself passed the loop Calc. The power supply for scanner is 5 V 4 amp.

Hi there, ProTrack is failing in the Loop Calc Phase check and Volt check. I was wondering if someone could help figure this out, Please. I think all the fails are related to 1 or 2 component!

I may have figured it out the Scanner fault. but not sure until I replace the relay 51 and 115.
both relay 51 and 115 are connected to Pin 51. When energized measured resistance between their contact is higher than the rest of the relays. Measured at around 280 to 290 mohms.
the rest of the relays measured around 120 to 180 mhoms. datasheet says 150.

relays are obsolete but thanks to jvthorsley, he posted the equivalent relay part #. I think I managed to burn a couple of relays while testing too. Kept forgetting to turn off the supply to the relay coil when solder / de-soldering line. I will be replacing 4 of them.

The failed voltages are reading slightly high. Have you tried running the Auto calc in the ProTrack (KJ3 and KJ4 ProTracks only).?
The most important troubleshooting tool is your eyes.

Al1234

No I have not tried running the Auto Calc on the unit itself I will try doing that a little bit later. I tore everything apart in the lab to rearrange and make some room.

Al1234

What are the voltages that need to be checked on The ProTrack?

1. Warm up the Protrack for 30 minutes.
2. Enter the Calibration menu.
Press Help button. Do not release it yet.
Press Menu button. Do not release it yet.
Press right side 4. button and release all three buttons.
Here, press the Auto on the right side to start the calibration.
The procedure runs for 20 minutes.

Run Workstation 3.5.4 with Win XP only.
Run the meter check in a Workstation (for this you need a 6.5-digit dmm, e.g. Agilent 34401)
Then try loop calc.
Maybe all values will be good.

Al1234

Thank you fetron. I am going to try this very soon.
What is the right side 4 button?
I have an Agilent 34410.

Fourth button down on the right. Here is a graphic that anyone with KJ3 and KJ4 models may find useful.

performed the Auto Calc. it passed the Loop Calc. I humbly Thank you guys, I appreciate you very much.
All that is left is repair the scanner test in WS.
waiting for relays to arrive.
I will update

hi everyone, I replaced the relays. but it got worse. now scanner fails in loop Calc almost on every relay I think.
it does not scan in the manual mode either, what I mean  is with out the computer. channels don't read the same.
I replaced 4 relays, replacement part #HE722A0510.

It's highly unlikely but , I thought i plugged in the 2 prong incoming 5V plug in the wrong jack on the board.

I make a point of taking pictures of work before disconnecting, but it looks like i don't have any picture...
there is J3, J4 and J5 Jack's on the board.
J4 is obvious but I thought maybe I swapped the J3 and J5 by mistake. can someone tell me which one the incoming 5v power connects to. ,
Also can I get schematics on the ProTrack Scanner please.
