Hi all,

Our confocal microscope’s power supply unit (biorad mrc-1024 confocal)
is out of order. It is an Ion Laser Technology (ILT) unit, model 5403B
(from July 1995).

We would like to ask if any of you might have the electricity circuit
scheme for this unit (or a similar one). It would be very helpful for
us for trying to figure out the problem there.

Trying to find the problem in our electronics laboratory, we’ve found
that the unit can’t operate and get power without being connected to
the other units (as it is connected when it works on our whole setup).

However, we don’t have the interlock plug for the interface connector
that might probably solve this. We wonder if anybody could please
direct us whether there's a way to jumper the connector/circuit such
that we could operate the power supply at electrician place, where it
stands alone, without bringing the other units that to his place.


Many thanks in advance,

Adi,

The Weizmann Institute of Science.

Sorry, the link to the news release does not work. Cleverly designed
Biorad web site! However, Zeiss should be able to help.

Adi,

You can make that jumper from parts in a good electronics catalog and
it shouldn't cost you much. Try these (www.mouser.com, www.alliedelec.com,
www.jameco.com). You might have to buy a plug and some cable and then
close the right lines but that is much cheaper than Zeiss's price.

When you find the messed up component(s) the catalogs should help you
get a replacement. There is a problem though, some times components
are custom designed and programmed. This can be a real headache, I've
had to tell people that I found the problem and they don't make the
solution any more. Then life gets real interesting.....

Thanks,

Kevin Cunningham

Dear Kevin,

Many thanks for your good ideas.

The thing is that for regular use, the interface connector is simply
connected to the computer and power supply gets voltage without any
need of interlock plug or jumper.

Now, as we had to fix the power supply unit, we took it alone to the
electrician, and we need a way to activate it without the other units,
and we don't have an interlock plug. The worse thing is that we don’t
even know what the right lines to close are, since we don’t have any
scheme of the electric circuit...

But thanks anyway

Adi

Dear Helpful person,

Many thanks,

I talked with Zeiss. However, as I was told, this ILT power supply
unit is old and its brand is not longer exist (for more than 10
years). He will make efforts to try and get a scheme, but he can not
promise he will succeed…
I thought that maybe somebody here might have one.

Thanks again,

Adi
