Dear friend thanks for your reply . Two lifts only for groupings other lifts have simplex.
Already I was contact to Mce but is not proper response. I have a manual but I was checked in the manual . I couldn’t get.

Whether we are the in front of swing panel. When we are facing this problem that time in the swing panel showed normal operation.

At the same time in the Group Superviser panel monitor also normal . There is no fault.
I was opening the F3 menu. There is no error at the time of issue .
So please help me friends.
