Hi Max,

I spoke to Curtis regarding your question about the last 2 digits. They tell me that the last two digits refer to the controller parameter settings and if I give them the different numbers they have look up tables and can tell me the differences. Let me know the number of the faulty controller and the one you have to replace it with.
By the way I sent you an email regarding Jungheinrich diagnostic software, could really do with your help on that one.

Hi Cristian.
Thanks for your mail. I have the manual, but it does'nt tell anything about the last 2 digits.
Best regards, Max

Hello Frits.
Yes I've send them an E-mail, but they did'nt respond to this question. All I know so far, is that pin configuration can differ for different models. Some controllers have spicial pins for fieldweakning etc. So it is not possible to replace one controller with an other. If I open the controller, the PCb's don't look the same, and also have different software. The controller I have to replace is a " 1207-0151 " Never seen this one, but friend told me it "maybe" could be replaced with " 1207-1101 "
Thanks alot and best regards, Max

See your email.
Regards
Cristian

Found this in the FAQ section of the curtis website, not of much help though: Did you try to send them a email, don't know if they are willing to help:

FAQ:

When trying to pick out a controller for my application, I see the desired model has some missing numbers. For example: 1204-2XX. What does the "XX" stand for?
The "XX" is a designation number that tells us what options are configured on a certain controller. Some of these options could be certain error detection configurations, software differences, or even an exclusive controller for a certain customer. We have some internal documentation which helps us figure out which controller would best fit your needs.

I have a motor controller that failed. It is a 1244-4401. I have an extra one on my shelf, but the model states it is a 1244-4403. It looks exactly the same as the old one. Will this work?
This is a tough question to answer just by looking at the model number of the controller without any supporting information. More than likely this will NOT be a "drop-in" replacement. Usually there is enough of a difference in the controllers, even though not externally apparent, that you will have some type of error occur. You will need to contact a Curtis representative and they will be able to research this and find out if it is possible to replace one controller with another.

Is there someone out there who knows what the 2 last numbers
means. I have several different curtis 1207-xxxx and I can't use them as is, without risk.
