Sitrans P Serie Z - problem

Tommy_cro Posts: 4 Rating: (0)	I have problem with Sitrans P Serie Z (7MF1564-3DD10-1AA1) pressure transmitter. When I connect direct Sitrans P to CPU 224xp, on analog input I have 0,5V when is 0,0V expected. In that range (0-0,5V) Sitarns P is in "death range" but at 0,6V to 10V works good. When I connect some other transmitter (from other manufacturer), on analog input I have 0,0V. Can someone tell me how to solve this problem? How can I get 0,0V on analog input? Is it problem in direct connection of Sitran P and CPU? Thank you in advance.

(After thatI have connected SITRANS P serie Z , with output signal 4-20mA to CPU224xp ( like this way http://support.automation.siemens.com/WW/view/en/25204813) and itwas O.K.) I think that problem is in Sitrans P! In galvanic separation!? Best regards, Tommy
