1) Connector dependent on the valve type (see "Technical data" and "Electrical connection\u201d).
2) With the SY(H)DFEn control system with analog interfaces, the plug-in connector X2 can not be used as actual pressure value input. Thus, a separate pressure transducer has to be used and connected to plug-in connector X1 in this case.
3) Only in connection with SYHDFE and spool design C (feature 2).
