The point in the operating sequence in which the lockout occurred will appear in the upper right hand corner of the display
(e.g. PURGE, PTFI, MTFI, or AUTO). On recycle-type programmers (e.g. EP260, EP270, or EP380, EP390 set for recycle
operation), the display will always indicate the LOCKOUT occurred during PURGE, even though the interlock could have
opened during Purge, PTFI, MTFI, or AUTO and failed to close within the first 10 minutes of purge following the recycle.
