Sequence Of Operation - Beckett GENISYS 7565 Quick Start Manual

Sequence of Operation

Burner States
1. Standby: The burner is idle, waiting for a
call for heat.
2. Validate Air: once the motor turns on
and if configured, the control will prove air
before pre-purge. This feature requires
either a pressure switch or a spill switch.
3. Valve-On Delay: Pre-Purge, the igniter
and motor are on while the control delays
turning on the oil solenoid valve for the
programmed time. This feature requires
either a Beckett Clean-Cut pump or an
external valve.
4. Trial For Ignition (TFI): If used, the oil
solenoid valve is energized. A flame
should be established within the factory
set trial for ignition time ("lockout time").
Ignition Carryover: Once flame is

established, the igniter remains on for the
configured carryover time delay to ensure
flame stability.
Run: The flame is sustained until the call

for heat is satisfied. The burner is then
sent to Motor-Off Delay, if applicable, or it
is shut down and sent to Standby.
7. Motor-Off Delay: Post-Purge, 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. This
feature requires either a Beckett
Recycle: If the flame is lost or if the

pressure or spill switch (if used) open
while the burner is firing, 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 flame is lost, until
it reaches the configured number 3 max
of retries. The control will then go into
Lockout instead of recycle. This feature
prevents excessive accumulation of oil in
the appliance firing chamber.

9. Lockout: The control has shut down for
one of the following safety reasons:
a. The trial for ignition (lockout)
time expired without flame being
established.
b. The cad cell detected flame at the end
of the Valve On Delay state.
c. Flame is lost while the burner is firing
and the pre-set time allotment is
expired. See "Recycle" (Item 7).
To reset the control from (soft) 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 qualified service technician.
To reset from Hard Lockout, hold the ACTION
button for 15 seconds until the SYS light briefly
turns from red to yellow.
10. 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.
