Operation
This procedure continues on the next page.
Mode
Startup The burner controller will enter the startup mode as soon as
there is a call for heat. This mode consists of the following
periods:
Safety
Valve-on-delay
Trial-for-ignition
Carry-over
Run The run mode starts and continues once the ignition carry-over
period has elapsed. During this mode:
The fuel shut-off valve is open (energized).
Pressurized fuel atomizes at the burner nozzle.
The flame is monitored by the cad cell.
Once the setpoint is reached (call for heat satisfied):
The output contacts of the temperature control open, inter-
rupting the circuit between terminal "T" and "3T".
The fuel shut-off valve is closed (de-energized).
The burner motor runs for the selected burner-motor-off
delay time (period), then turns off.
The burner controller returns to the idle mode.
If the flame is lost during the run mode:
The burner controller enters the recycle mode.
Recycle The burner will enter the recycle mode when the burner stops
firing due to loss of flame. During the recycle mode:
The diagnostic light on the burner controller will flash in two-
second intervals.
The burner will attempt to automatically restart.
Flame must be detected during each restart attempt. If
no flame is detected, the burner controller goes into
burner fault lockout mode.
The burner controller will wait 60 seconds between
restart attempts.
After three restart attempts in which the call for heat is
not satisfied, the burner controller will go into burner fault
lockout mode.
If the call for heat is satisfied, the recycle counter resets.
