Figure 3.4: PB-1525 Burner Controller in the Stabilizing State
As depicted above, the System State is “Stabilizing”. The ignitor has shut
off (indicated by the absence of the “I” on the display). No new indicators
have been displayed; however, we do see that the flame sensor value will
change in this state (shown here as a value of 74). We also see that the
Feed motor will come on and off based upon the programmed values
(indicated here by the “F” on the display). And, we see that the
combustion blower speed is at the Low setting (indicated by the bar
graph) Shown on this display is the total number of running hours of the
system (indicated as 13 on the display). This display area will
automatically cycle every 2-3 seconds between Hours, Starts and Resets.
If the system fails to maintain a healthy flame during the Stabilization State
the system will revert to the Igniting state an attempt to re-establish flame.
The system can be forced into the Shutting Down State by pressing and
holding the Disable button for five seconds.
Firing
The Firing state indicates the system has established a healthy flame in the
burn chamber and is firing at the full firing rate set up by the Certified
Installer. In the Firing state, the unit is running the combustion blower at
high speed and pellets are being fed into the burn chamber every 15
seconds. The system is continuously monitoring the flame sensor for the
presence of proper flame. Figure 3.5 below illustrates the controller in the
Firing state.
