Hello, i have a problem with couple of schindler 3300 elevators, i have to lock 2nd floors, but on some of them the functions ZB1 for pin code and ZBC1 for car call lock off doesn't work. Do you have any suggestions.
Thank you in advance.

I think you 3300 is the same as 330A here in the states. On the CPB board look for JCKL1 if you jump pin 1 to pin 2 that will turn on security for the lowest floor. pin 1 to pin 3 the next floor up. And so on and so on. If you jump 1 to 2 and nothing happens you will need new software. See post about 330A as it seems we have the same problem.

Schindler's newest traction car with the controller in the jamb is a 3300. From what I've heard, totally different than any other Schindler unit.

No-one thing is the same as their other units. The MTBC is supposedly atrocious.

Yes thats the elevator with controller in a jamb, the only thing that works is changing sim cards, that have this function enabled. Maybe anyone has tried to copy them and knows if they are blocked or you can just buy any sim card reader and copy them?

I haven't seen a 3300 in about a year but the last 1 I installed didn't have a sim card and the only way to lock out hall calls was to solder to the board engineering said it was very difficult to make work
