Otis 311

Having a leveling issue, some floors are perfect while others are off a quarter inch.No reason for vanes to have moved.Wont recognize learn trip.

What do you mean by won't recognize?

Tool says abort , car stops before reaching the needed 0 value at the bottom landing to initialize learn run.

Try replacing your batt ram chips if it wont take learn run

Bump up ntsd tolerance to about 500 and try it. Then set it back.

When those Dallas RAM chips have been the issue, it has worked for me to just swap the 2. They aren’t bad, just like glitched. Of course I don’t know if this always works.

Check and make sure your sensors are clean and dont have hoistway junk and dust. run the car down an inspection and make sure NTB goes lower case IN (menu or module ) M 2-1-3-1 i think then make sure ET1.

Hey guys I really appreciate the help, I will hopefully get it fixed and will reply back with what the issue was, thx a million!

Only one batram chip is really used, the other is backup. You are leaving the bad one in the backup socket on the board.

If increasing your NTSD tolerance does the trick, that is a good indicator that your NTSD vane is the wrong length.

---------worn sheaves on machine and cables will cause cable slippage too much slippage throws the hoistway counts..off

Appreciate all the help guys, Len you where spot on, cables are slipping just enough to cause the count to be off.Thanks for your input!
