Hi

I have a Schindler Bionic rel 4Controller. We have the 500ma Fuse on the SPHRB Module in the shaft blowing just as the lift stops at floor level and is about to open the doors.

It will also blow if you use the shaft access device ( (KNET switches )

Has anybody had this issue before and know of a probable cause.

Or does anyone have some information on the SPHRB Module that they can share

Thank you
