Alarm Acronym Composition Squelched By (*) (**) (***)
FST Cycle
Limit
FSCL
The “FST Cycle Count” exceeds the “FST Cycle Limit”
“FST Cyc. Cnt” >= “FST Cyc. Lim.”
It is cyclically check (period = 30 seconds).
The check is interrupted during Calibration, Signatures and
PST executions.
• “Al. FSCL En.” = “No”
• “Reset Alarms” command
• Power-on Reset
Slow Open
Break Time
SOBT
Last “Maintenance Opening Break Time” is slower than the
