Falcon Lead Lag Appendix E
E-20
This page shows the system setpoint, actual header temperature, and status of each slave boiler.
The possible Slave states are:
•Available - boiler is ready to use but is not currently firing.
•AddStage - stage is getting ready to fire.
• SuspendStage - stage was getting ready but is not needed.
• Firing - boiler is currently firing.
•OnLeave - boiler is operating for some other demand source having higher priority than LL Slave.
•Disabled - boiler is locked out or disabled in some way.
• Recovering - slave is in time delay before becoming available.
If the state of any slave is Unknown it will be removed from the display.
Note: If during operation an alert
‘NO SLAVES AVAILABLE FOR LEAD LAG’ occurs:
While not a lockout condition, this alert will close the alarm contact in the Master host. The
alarm can only be reset at the Master host controller by opening the panel and pressing the RESET
button on the Falcon controller.
The Falcon has extensive diagnostic features for monitoring individual boiler and system lead lag
performance, including alert/lockout history and real-time data trending. Refer to the boiler manual
and to the Falcon controller and display manuals for additional information.
