Re: [RE-wrenches] mate 3s locking

[Jay]

Hi william

Very tech fix with the relay!

Fortunately or unfortunately there is no reliable web at the location but 
someone who manually checks things. 

Yes the 3s still has some of the same problems 

Thx

Re: [RE-wrenches] mate 3s locking

[William Miller]

Jay:



I have problems with all of my Mate3 and 3s controllers locking up.  So
much so that I have implemented the following steps:



1. For most installations I leave the hub wire cover off and label the
Mate lead.  Clients are instructed to unplug and re-plug the Cat5 lead
whenever the Mate locks up.

2. On one installation I have a Control By Web unit ping both Mate3
units every 5 minutes.  If either fails to respond after 3 attempts, a
relay opens and closes the Orange/white leads which power cycles the
Mates.



Locking up of Mates is a fact of life with Outback equipment.  I love the
equipment and I hate the equipment.

Hello All

And

Hello Jay

I just asked the tech support boss on this as I had no idea.

He has a test setup that allows him to switch individuals lines on the cat5
cables.

We can duplicate Jay’s  screen shot below by opening the some of the lines
to the cat 5 cable.



So as a start try replacing the cat5 between the Mate3S and the Hub.

Using the silicone grease that comes with a Mate is never a bad idea.

If your customer does not have a cable on hand I would try removing the
cable several times perhaps that could help to dislodge any corrosion or
dust on the connections.



I hope this helps.

Re: [RE-wrenches] Microfractures

[Jerry Shafer]

Andrew, Wrenches
While in Hawaii, l had modules that had fractures, some showed up in low
performance, some did not and l don't recall there being a wobble on the
high side. I would suggest inspecting what the modules look in question.
Most of the time the cracks are visable and may look like worm tracks, they
will be across the modules. Also look for what appears to be cigarette
burns, this is trace arcing or at least overheating of the trace and they
can appear at the interconnecting trace or main traces mostly at the change
in direction of the trace. I have also had bad bypass diode connections
have issues effecting performance curves.

Re: [RE-wrenches] mate 3s locking

[Lones Tuss]

Hello All

And

Hello Jay

I just asked the tech support boss on this as I had no idea.

He has a test setup that allows him to switch individuals lines on the cat5 
cables.

We can duplicate Jay's  screen shot below by opening the some of the lines to 
the cat 5 cable.

[cid:image003.jpg@01D47DA9.B5D61C00]



So as a start try replacing the cat5 between the Mate3S and the Hub.

Using the silicone grease that comes with a Mate is never a bad idea.

If your customer does not have a cable on hand I would try removing the cable 
several times perhaps that could help to dislodge any corrosion or dust on the 
connections.



I hope this helps.

Take Care All

[RE-wrenches] Microfractures

[Andrew Truitt]

Wrenches - Does anyone have experience getting electroluminescence (EL)
test results from module manufacturers?  I just shot some module IV curves
as part of an acceptance test and they all show some irregularities on the
vertical slope that Solmetric says are indicative of microfractures:

It seems the optimal course of action here is to perform EL testing on a

even if we do determine that the damage occured after modules left the
factory, how could it be proven if its the shipper or the EPC at fault?  I
foresee everyone pushing back and invoking the performance warranty as the
backstop if issues pop up in the future (assuming nothing shows up during
performance testing next month), but the last thing we want deal with is a

Re: [RE-wrenches] 2 wire to 3 wire start on Older ONAN 12.5JC

[Tump]

ATKINSON ELECTRONICS, INC.
Web Site: www.atkinsonelectronics.com  

While these might seem complicated they are well thought out and  easy to 
program despite the many pages of instructions. A simple jumper wire and then 
pressing the select button will scroll you thru the various settings. Using a 
DVOM one sets the voltage 0-5 vdc for the setting. One can set them up for 
monitoring house battery voltage, starter battery, daily run-monthly run. Once 
you understand and are not overwhelmed by the enclosed paper work they work 
well.

Need fuses to protect the unit and a momentary on button to reset the unit, we 
usually install them in a plastic box w/ a clear cover so we can see indicator 
lights & or lock out light requiring a push of the momentary button.
