sie-enauto Posts: 47 Rating: (0)	Dear Metwally Mustafa It is importance for me because I also asked Siemens "can we replace QRA50M by QRA53... " but they told me "Can not". I asked what is problem, why it can not replace but Siemens did not give me any result. I read manual of QRA50M they told me shuttle timing is 3 time per second. They only told me that QRA53.. can not work with LFE50 then I want to know why it does not work? Thank you
