Re: all reefer container problems/daikin/carrier/thermoking/mitsubishi
Hello reefermechanic
I'm an reefer electrician but new to this job. I have a problem on a carrier reefer, model 69nt40-541-015 wich has a ML3 controller. In proximately one month it fried 2 controllers. I had the container not working at all, replaced the controller, it worked fine, did the PTI, went on a trip and when it returned it was just like the removed controller. sometimes it works but giving alarms, other times the display and reefer are completely dead. It has 2 pins on connector KA (KA9 and KA10) that are the power supply to the controller, ( 33V betwen them) I think. Does the controller have any other power supply? and if not do you think that the transformer can have some sort of problem? by the way do you know the language of programming used in these controllers? is it ladder or FBD or is it something mor complex like C++?

Re: all reefer container problems/daikin/carrier/thermoking/mitsubishi
Hi Guys, I'm looking for a service manual for a MHI CPE52-* with a MMCC111 controller.
I have looked on the internet and have started looking through this forum. I am at work at the moment and can't spend all day looking for this. If someone could give me a heads up it would be greatly appreciated.
Thanks

Re: all reefer container problems/daikin/carrier/thermoking/mitsubishi
Hi!! I'm doing some research about the reefer container. Just want to know according to your guys exp, which brand/manufacturer of the reefer container is the best interm of quality/efficientcy?
From my understanding there are 4 big players in the market+Mearsk (Have their own starcool)
-Daikin
-Carrier
-Thermoking
-Mitsubishi
-Mearsk (Starcool)
And what is the market share of these 4 manufacturer+ Mearsk?
If i want more info about the reefer container business, where can i get the info.
Thanks

KA9 and KA10 are two separate 18vac power supplies for the ML3 controller which should be referenced against KA12 (Ground). So 33v seems to be around normal if measured across both and the control transformer would seem to be working. Are both evaporator fans working as there is an Internal protector (IP-EM1 and IP-EM2) which are embedded into the motor windings. A shorted evaporator motor can back feed 380v back into the controller through the IP lines usually this is instant once a motor burns out but may take a little longer depending on the severity of the burn out.
The programming language for the Carrier microprocessors is properietary

Re: all reefer container problems/daikin/carrier/thermoking/mitsubishi
hello all i am a refrigeration mechanic from australia and do alot of work on commercial airconditioning but have never seen or worked on any transport refrigeration gear
i have a customer who has the back of a truck at his house that is refrigerated by a thermoking unit
inside it has 2 evaporators and he wants 1 of them moved about 3-5 metres from its current location inside the back of the truck
is it as simple as just pumping down the unit, extending the pipes and all electrical connections or is there something else i should know?
can these units be pumped down like any regular unit so that i can cut the pipes going into the evaporator?
the evaporators have 3 pipes going into them, i would assume one is a hot gas defrost?
will extending the cables effect anything such as the thermostat probes which will obviously also have to be extended??
thanks for any help, the reason for so many questions is that i will be approx 800km when working on this unit so i need to be prepared as i cannot get parts easily
thanks anthony

No problem extending the wiring or the piping.
Is this an older diesel powered unit like an RD-II TCI / TLE?
I recommend against trying to pump down the unit, technically it is possible (high side pump down) but not recommended. You're best to recover the complete charge, makes it easier for nitrogen purge when soldering the pipes and evacuation. There is a mess of valves in those units and chances are you're going to have one leaking past a little bit so you'll never get a solid vacuum. When you evacuate you must do a three point (suction, discharge, receiver)

Re: all reefer container problems/daikin/carrier/thermoking/mitsubishi
hello everyone can you please help me with my problem regarding on carrier reefer container because i found out that the controller is damage. I replaced new controller but currently not working yet because i can't configure it. I found a spare of SRAM to cofigure it, but when i put it doing the right procedure on the manual it still not working. My question is, do i need to download new software of ml3 and copy to the SRAM to configure it? I also have a spare of card (I'm not sure if there is program of ml3 inside) and adaptor of SRAM but i don't have pc that can connect it. Also, i cannot put directly the card to the container controller because the connector is for SRAM only. I also try to go in the site of carrier to download this program ml3 but i cannot access it because of password. I want to use emergency bypass but the problem the commodity inside is wine therefore i cannot directly run the reefer to cold mode. Please help me on this problem and if there is any suggestion I appreciate it. Thank you

Hi Friend. pls check Cd-18 and Cd-20 within codeselect menu via keypad. And also pls check the unit model number. Unit model label left side of compressor and reply to me. see you. reefermechanic.

Re: all reefer container problems/daikin/carrier/thermoking/mitsubishi
Friend this is the Cd-18 5148 (i also have a 5318 program),Cd 20 don't exist, and the unit model number is 69NT40-541-301. When I check the reefer this morning it has too many alarms specially on safety device and it's not working. The setting in code select is in default and i try to use the emergency mode but it is not safe for the commodity because it will have too much cooling. Please give me advice for this problem. thank you very much

I am yet to get a model number from the client because e recently got Injured at work.
Could you please explain why I must do a 3 point vacuum? I mostly work on air con systems and only have do high and low side? My gauges are only the standard type with 3 hoses not a manifold set
I look forward to your advice. Thanks

A three point is required due to the disaster of solenoid/check valves in the system. The condenser inlet and suction line solenoids are normally open but the rest are normally closed. In this system when one compartment is calling for heat and the other for cool the compartment calling for heat becomes the condenser. Fun **** when valves start to stick intermittently. On older RD-II the electrical is just as fun.
Attachment 10335
This is a TCI system with a host attached to the main unit. A TLE has no host and 2 remote evaps. The plumbing is the same.

Ah I see. This stuff is confusing to me compared to my usual stuff. If I were to use solenoid coil magnets how many would I need to have all the valves on the system open

Feom what I can see there. Is the hot gas defrost discharge line always running to the evaporators and then is controlled by solenoids inside the evaps? Does this mean even if pumped down there would be gas in that line?

Yes, there would be gas in that line. If you pump down and equalize at the compressor the condenser inlet check valve should hold the charge but I wouldn't trust it. For all the time it takes I would pull the charge. It should be 404a but depending on age it could be 502. As far as mechanically opening the valves, a magnet on each liquid line solenoid should do it. I like the three point, it pulls a better and faster vacuum. If you have an extra port on your pump, hook the receiver directly to your vacuum pump. If there still is shraders on compressor I'd yank them too, with service valves they are redundant.

Thanks for your help. There is no way I'd put that muh trust in a check valve that's for sure. Another stupid question. Is there anywhere in particular I should reclaim from?

No stupid questions. If the unit is running pump out from the receiver into your recovery tank, you'll probably get at least half the charge or most of the liquid, more if you cover the condenser. Then recover the remaining liquid from the receiver after that switch to your compressor connections.

Thanks for your help.
So if I reclaim the unit where do I need the solenoid magnets?
Then
Once I've done that I can extend the pipes and vac it out and recharge it
Will extending the cables effect the thermostat probe?

Extending the cables shouldn't affect the probe.
Mechanically open the hot gas or liquid line but not the suction line.

Re: all reefer container problems/daikin/carrier/thermoking/mitsubishi
Just a quick query…..
I have a NT40 reefer used as a static chiller (+5 setpoint), and this has been working well until the last few days when once or twice a day, the power trips at the breaker inside the reefer panel. The incoming mains supply is steady at 385v and everything seems fine. I reset it and it works again. There are no alarm codes. The only change is that the temp here has risen to around +40 in the last few days and this may have an effect.The trip mostly happens in the afternoon when the sun is shinning directly onto the working end of the container.
Have you heard of this happening in the extreme heat ? I am really hoping that its not the compressor windings starting to earth. It’s has the water cooled option but is set for air cooled.
Any wise words please

Hello...no the problem isnt solved yet as it only seems to trip the CB when its very hot (+40c). Its works well day after day when its below this ambient temp. I have set the amps to 21. Its not an isolated case and can be common as the summer draws near here in the middle east. I am constructing some shading to see if that helps.
