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.
