Pin assignment CPX−8DE−D with sub−base
CPX−AB−4−HARX2−4POL
On this sub−base only the sensor supplies for the inputs Ex,
Ex+2, Ex+4 and Ex+6 are available. These supplies are used
in pairs
by the inputs Ex/Ex+1, Ex+2/Ex+3, Ex+4/Ex+5 and
Ex+6/Ex+7. The diagnostic messages are therefore only for
the inputs Ex, Ex+2, Ex+4 and Ex+6. The inputs Ex+1, Ex+3,
Ex+5 and Ex+7 do not generate a diagnostic message.
