Every time swindler or otis does crap like this it hurts there reputation. When are they going to figure out that if they'd actually do the job that they were paid to perform, they wouldn't lose service. Stealing the customers parts so they can blackmail them into service is pathetic. And what does this say for the former service guys character? Stealing for your company? WTF! Sorry, just venting a bit.

I'll see what I can get scott.

most property managers leave the manufacture due to prices not lack of maintenance. manufactures like to keep their technology to themselves like any other tech company. we arent working on relay based stuff anymore. best thing is to bow out gracefully, leave the small parts/prints, and wait for the prop. manager to call back but for cheaper price.

If you have the SIM (SDM chip), the CADI is not very relevant. With the SDM chip, CAT 1 and CAT 5 tests are easily performable, as well as troubleshooting and setting different parameters. Without either, you would want the customer to demand an upgrade to 2.18 software, which allows enough functionality to make retention of the job a possibility. Unfortunately, this is something the customer needs to demand, as SEC will not listen to another company's requests.

The purpose of the CADI is more for initial set-up and to make in depth parameter changes.

One other tactic to try is to get the consultant involved if one has been involved in the maintenance bidding process. They can be 'quite persuasive' in getting SEC to leave the SDM chip on site or in upgrading the software.

Good luck.

Wow, thanks for the info. really appreciate it, as we are definitely taking the unit on without the sim card. Customer has been informed of the problem, he contacted schindler, and they informed him the sim card was proprietary equipment, and that the car would function properly without it. Customer is also so upset with schindler, that he is willing for us to take the service regardless of the possibility of us not being able to fix the car at some point. I am going to contact the owner, and inform him of the info you gave me. thanks again, would be nice to learn how to work on these cars.

From what I understand the on board diagnostics are all loaded on the SIMM. Without it the CADI will be required for pulling fault codes and possibly even resets. Very difficult to support without the SIMM. Supposedly an early version of CADI was leaked out but I have never seen anyone with it nor have I been able to find it. They have a special telegram they can send to the CPU that will invalidate the SIMM and make it unusable so, just because the job has the SIMM DOES NOT mean it is functional.

Not true. Some very basic fault codes are available on the base SMLCD without even the SIM card. As stated above, with the software revision, you have more than a fighting chance of retaining the job. Leave a thread on the forum and I'm more than willing to help with fault codes.

Also, Schindler will no longer even bring the SDM chip to the job after construction turnover unless Schindler's SRM (Schindler Remote Monitoring) has been installed. That is how they can invalidate the SDM chip if they lose the job and are unable to gain access to the controller. Another note-don't bother demanding the SDM chip from Schindler. The chip is not on the customer's bill of sale, and won't be provided as it is considered property of Schindler.

I have seen customers with a bit of clout (a lot of properties and units) strong arm Schindler into leaving the SDM chips in the controllers. But I have also seen a few customers fail when trying.

As stated above-version 2.18 or above is the way to go. The company I work for has been successfully maintaining TX-R5 and 400A units with and without the SDM chip. It's just that without it you need to have some prior experience with the equipment.

Good luck and don't hesitate to ask questions in the future. Here to help.

A few years back Schindler installed 2 400As at fairly large University in my area. As part of the the University's elevator spec all the elevator contractors are required to provide a full set of diagnostic tools and manuals to the university on any new installations and mods. In this case Schindler refused to provide the SDM chip even after it being in the specifically spelled out in the job spec. The University then held a large chunk of money from the General Contractor after the building was finished. Long story short, another company was contacted to replace the 400a controls and fixture before Schindler's warranty had even expired.

God help anyone who gets a 3300.You know,the belted machine-roomless deal.
Never had any major problems out of the rest of the types,pretty basic.
I have had a few crip boards go bad,mostly with the HW door circuits on the board.

Anyone have a manual or at least a fault code list for 400a’s. I know I’ll need this in the future. The three controllers we have service on still have SIM cards.
