Hi Indirtwetrust,

Yeah that makes sense, so they're either on or off depending on the floor.

Level up and level down are used because on the MCE controller when this is happening it constantly says level up then level down in the monitoring screen. It just isn't using the inputs that the book mentions (SLU and SLD).

While the lift is relevelling, STU and STU stay on but it switches continuously between ULM and DLM (up levelling marker and down levelling marker) which makes me think it's got something to do with the magnets or switches but the magnets are glued and not noticeably damaged. I don't think it's the cylinder as when a load of people get in the car it maybe moves 10mm max. Otherwise the system is holding pressure. With the ball valve closed it holds 20 bar and drops 5 bar over 10 to 15 mins which is ok. With it open, no drop at all. The car doesn't sink with the power off and ball valve closed either.

When this event occurs is mostly when people walk into it from a floor or leave the car and then it starts but only about 2 times on the 2 lower floors, when this happens on the top floor it can sit there relevelling about 10 times before it will actually leave regardless if it has call on for another floor. The only floor it does it with an empty car is on the top floor but not every single time.

The only thing we haven't dug deep into yet is the tape reader switches. The magnets especially on the top floor are in the correct position glued so we can't adjust them anyway.
