Mecmar burner cutting out.

[Chae1]

Got a diesel mecmar drier. Drying seed at moment and burner keeps cutting out.

Air probe set at 70. Whenever cereal temperature reaches 40 it struggles to regulate air probe. Noticed it going up to about 85 and this causes burner to cut out.

Any ideas how to stop this happening? Annoying when you leave it for a bit and come back and burner off and grain cooled.

Think mecmar/MacArthur (mecmar dealers/importers)are on here somewhere.... Not sure on their user name. They would have a fair idea of how to fix it.

Edit. Found them ... @McArthur Agriculture

Magic eye dirty? Solenoids opening and shutting correct. That's where I normally start.

Usually need to put in smaller jets for seed, first jet too big and heats hotter than you have drier set for without letting second jet modulate the temperature.

Have been drying malting barley all season on same settings and been fine. That would make sense that this would be problem though.

Had all filters/jets out and cleaned.

I would ring them up always been very helpful and 9 times out of 10 sorted over phone. Normally very reliable dryers so more than likely something trivial.

Your welcome to give me a call on 07970 053327. In the [unlikely] event you can't contact Mecmar.

I suspect that primary burner jet is perhaps doing nearly all the work. Ambient temperature is also high (down here at least) which makes its life easier still.

Exactly as david said you need smaller jets in. Please dont hesitate to call us though as there is always someone on the phone. We would rather point you in the right direction than let it cause frustration.
Main number is 01724 747110.. Andrew is on it today. My number is 07943330290. Save them on your phone. But for this case it is definitely a case of jet size. Sellars have jets, easy DIY job or im sure Davie Mac will give a hand.

Thanks. Are you from Mecmar?

Also a quick thing you can do in the mean time is set the burner to run on single flame only. Unter the red cover, at the front there are 2 small black rocker switches. The one on the right has I or II. Out it to position I. Then only the first flame will come on. You will be heating up slower but will at least not cut out until the job is done.

Yep!

 

[Chae1]

Yep!

Cool. Got your number now.

 

[spikeislander]

me too

Presumably that is on the later burners? Never noticed switches on Press 2G..

 

[MGE90D]

Correct. But you could a hieve the same thing on th Pres2 by disconnecting the 2nd stage solonoid. (The one of the pair on the inside)

Does the air temperature alarm illuminate then?? I have similar issues with burner cutting out only sometimes drying feed barley air 80 grain 40, service guy says it could be the air probe faulty

 

[Wjb7030]

Yep!

I have mecmar fsn 15 drying feed barley air 80 grain 40, air temperature alarm keeps illuminating and burner cuts out, only sometimes it does it,mid cycle, if you start burner again it finishes batch no problem, I haven’t been beside it when it happens but only happens now and then ,works no problem some days

 

[bravheart]

As above with jet sizes, the random overheat problem could possibly be because the ambient air temperature is higher this year.
