Sequence Of Operation; Reset Button Operation - Beckett GeniSys 120V Manual

Sequence of Operation

Burner States
1. Standby: The burner is idle,
waiting for a call for heat.
2. Valve-On Delay: The igniter and
motor are on while the control
delays turning on the oil solenoid
valve for the programmed time.
3. Trial For Ignition: The oil solenoid
valve is energized. A fl ame should
be established within the factory
set trial for ignition time ("lockout
time").
4. Lockout: The control has shut
down for one of the following safety
reasons:
a. The trial for ignition (lockout)
time expired without fl ame being
established.
b. The cad cell detected fl ame at the
end of the Valve On Delay state.
c. Flame is lost while the burner
is fi ring and the pre-set time
allotment is expired. See
"Recycle" (Item 7).
To reset the control from lockout
click the button 1-second.
NOTE: A recurrence of the above
failure modes or a failed welded
relay check could cause the control
to enter a Hard Lockout state that
must be reset only by a qualifi ed
service technician.
To reset from Hard Lockout, hold the
reset button for 15 seconds until the
yellow light turns on.
5. Ignition Carryover: Once fl ame is
established, the igniter remains on
for 10 additional seconds to ensure
fl ame stability.
6. Run: The fl ame is sustained until the
call for heat is satisfi ed. The burner

is then sent to Motor-Off Delay, if
applicable, or it is shut down and
sent to Standby.
7. Recycle: If the fl ame is lost while
the burner is fi ring, the control shuts
down the burner, enters a 60 second
recycle delay, and repeats the
ignition sequence. The control will
continue to Recycle each time the
fl ame is lost, until it reaches a pre-
set time allotment. The control will
then go into Hard Lockout instead
of recycle. This feature prevents
excessive accumulation of oil in the
appliance fi ring chamber.
8. Motor-Off Delay: If applicable, the
oil solenoid valve is turned off and
the control delays turning the motor
off for the set motor-off delay time
before the control returns to standby.
9. Pump Prime: The igniter and motor
are on with the oil solenoid valve
energized for 4 minutes. During
Pump Prime mode, the cad cell is
disregarded, allowing the technician
to prime the pump without having to
jumper the cad cell.
