4.1.7 — Lockouts, Holds, and Alerts
The CB Falcon implements two kinds of faults: lockouts and alerts. The Falcon will also annunciate hold condi-
tions which automatically clear when the condition is removed or satisfied.
Lists of fault codes and alerts can be found in Appendix A, CB Falcon Control.
LOCKOUT
• A lockout causes the boiler control to shutdown and requires manual or remote reset to clear the lockout.
• Always causes alarm contacts to close.
• Logged in lockout history in controller non-volatile memory.
ALERT
• Any fault condition that is not a lockout is an alert. Examples include boiler control abnormal conditions, faults
from non-safety functions, etc.
• Alerts never require manual intervention to reset them; they are for informational use only. Normal operation
continues.
• Alerts are logged in a 15-item volatile alert history sorted in chronological order. Only one instance of each alert
code occurs in the history, corresponding to the most recent occurrence of that alert.
HOLD
• A hold prevents the boiler from continuing until the hold condition is satisfied.
• Holds are not alarm conditions and are not logged in memory.
