Hi guys currently working on a Schindler bionic 7, had the following codes 1556, 1557, I have had high ohms on one of the NC contacts on SF1 which In turn have replaced these contactors SF & SF1 the drive type is a biodyn 25, I am currently locked out of the controller as Schindler have not had the lift for 2 years but have decided to perform a software update start of this year and I’m locked out of menu 70 even with Modutool connected I can only enter 702, I am wanting to check the states of the contactors, I’m possibly looking at a drive fault, has any one used the newer Cadi on these lifts to open them up, just after a bit of advice thanks
