Hie guys.

I have just finished a degree in electrical engineering and I am still new and fresh to the elevator industry.I am having problems fixing an elevator I am working on .Its displaying the KONE fault code 0036 .When going up directly NON STOP from ground to 12th and final floor it's working perfectly fine.Even going up while stopping at different flows it's working perfectly fine.

The problem is coming when going down. It only works perfectly fine if you are stopping at very floor. The moment you try to bypass 3 or 4 or 5 floors or car call from 12th floor directly to ground ....the main contactor is being released during drive and the elevator is stopping immediately.

How do I address this issue.Please help. .thank you
