Beckett GENISYS 7559 User Manual

Standby: The burner is idle, waiting 

for a call for heat. 

Valve-On Delay: The igniter and 

motor are on while the control delays 

turning on the oil solenoid valve for 

the programmed time.

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.  The pre-set time allotment for 

relighting is exceeded.

d.  Failed welded relay check.

If the control detects a welded motor 

contact, the motor only will cycle 5 

seconds on, 5 seconds off, 3 times 

before locking out. 

  To reset the control from lockout 

interrupt power for at least 2 seconds.

Ignition Carryover: Once fl ame is 

established, the igniter remains on for 

10 additional seconds to ensure fl ame 

stability.  

Run: The fl ame is sustained until the 

call for heat is satisfi ed.  The control 

then switches to Motor-Off Delay, 

if applicable, or it shuts down and 

returns to Standby.

Relight: If the fl ame is lost while 

the burner is fi ring, the control 

immediately repeats the ignition 

sequence.  The control will continue 

to Relight each time the fl ame is 

lost, until it reaches a pre-set time 

allotment.  The control will then 

go into Lockout instead of Relight.  

This feature prevents excessive 

accumulation of oil in the equipment’s 

combustion chamber.

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. Note that to 

utilize the motor off delay, power must 

remain to the red wire after the call for 

heat ends. (Enable input turned off, 

see Figure 2.)
