I have a t3 fault that's always coming in near the top floor when penetrating ets. Upon further investigation i noticed the bracket that holds the vane in place is turning on ds2 and ds4 on the ets board momentarily. My question is does ds1 and ds3 have to come on first before ds2 and ds4.(is there a sequence?). Does this cause the elevator to stop and than reset itself? Any info would be great. Thanks in advance
