Hi,

I am having problems with an MCS220 that after some time(can be minutes, hours and some time days) while is starts to move from any floor it stops like 1 inch higher than the floor.

By searching to fix it I found out that the contactor triggers and drops after 1 second because the LED *BC* is not turning on, if the BC is on while starts moving the lift works properly.

Do you have any ideas what can be ? This is my first otis with problems.

Lift details :
6 pers.
5 floors.
