Hello Good day to all, we are encountering fault 152 NTS STOPPING FAULT on a Monospace elevator with KDM Drive.
Fault usually appears after long run from top to bottom or vice versa but resumes to normal automatically and after car call is registered.
We have already replaced Car Guide rail shoe to ensure Magnet switches does not go out of alignment, replace DCBG, perform Load testing, change Magnet switches 61 and 77 but still the fault still persist.
We can perform test run and complete shaft setup however after some time fault 152 is encountered
Could anyone share their experience and solution about this, Thanks in Advance Vators
