OMPATIBILITY
The current SE-601 has been enhanced with the
addition of non-volatile trip memory for the fail-safe
relay operating mode. Prior to hardware revision 01, a
mechanical flag was used instead of non-volatile
memory. The current revision of the SE-601 can directly
replace previous revision-00 units. The hardware-
revision number is listed on the SE-601 model/serial-
number label affixed to the SE-601 enclosure. Both
generations are compared in Table 2.
