Beckett CF1400 manual Wire the Burner, Electrical shock can cause severe personal injury or death

Section: Wire the Burner

Low-fire/high-fire operation – The fuel unit nozzle port pressure is factory set at 300 psig.

○At high fire, full pressure (300 psig) is applied at the oil nozzle, causing full input.

○At low fire, the by-passing is done inside the fuel unit when the by-pass valve operates.

○This by-passing of oil reduces the oil pressure at the nozzle (to between 125 psig and 175 psig), reducing the input.

Incorrect Wiring Will Result in

Improper Control Operation

yGeniSys 7505 Control wiring label colors may not match the wire colors of the burner or other manufacturers’ controls.

yThe GeniSys Control should be wired according to the appliance manufacturer’s instructions.

Table 3 – Fuel Unit Gearset Capacities

CF2300	B2TA-8852	39

The fuel unit nozzle port pressure is factory set at 300 psig. Some

original equipment manufacturer burner applications may call for a lower pressure to obtain a required firing rate. Do not change this pressure unless directed to do so by the appliance manufacturer.

Wire the Burner

Electrical Shock Hazard

Electrical shock can cause severe personal injury or death.

yDisconnect electrical power before installing or servicing the burner.

yProvide ground wiring to the burner, metal control enclosures and accessories. (This may also be required to aid proper control system operation)

yPerform all wiring in compliance with the National Electric Code ANSI/NFPA 70 (Canada CSA C22.1).

Install the burner and all wiring in accordance with the National Electrical Code and all applicable local codes or requirements.

Wire the burner in compliance with all instructions provided by the appliance manufacturer. Verify operation of all controls in accordance with the appliance manufacturer’s guidelines.

See Figure 13 (7505P) or 14 (7184B) for a typical wiring diagram (for reference purposes only).

Fire or Explosion Hazard

Can cause severe injury, death, or property damage.

yThe control can malfunction if it gets wet, leading to accumulation of explosive vapors.

yNever install where water can flood, drip or condense on the control.

yNever use a control that has been wet - replace it.

Typical Burner Sequence of Operation - 7505 Control

Refer to the appliance manufacturer’s wiring diagram for actual specifications.

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 flame 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 flame being established.

b.The cad cell detected flame at the end of the Valve On Delay state.

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 qualified service technician.

To reset from Hard Lockout, hold the reset button for 15 seconds until the yellow light turns on.

5.Ignition Carryover: Once flame is established, the igniter remains on for 10 additional seconds to ensure flame stability.
