Electrical Shock Hazard
Electrical shock can cause severe personal injury or death.
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:
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 11a (7505P) or 11b (RM7897A) for a typical wiring diagram (Diagrams are for reference purposes only).
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.
Fire or Explosion Hazard
Can cause severe injury, death, or property damage.
yThe control can malfunction if it gets wet, leading to accumulation of oil or explosive oil 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 - GeniSys 7505
Refer to the appliance manufacturer’s wiring diagram for actual specifications. Note: GeniSys 7505 Control on CF2500A only.
1.Standby: The burner is idle, waiting for a call for heat.
2.
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
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.
6.Run: With a flame established and the control continuing to detect a flame, the burner will operate in the RUN mode until the load demand is satisfied or a limit opens.
a.If terminals RC1 and RC2 are jumpered, the burner operates in the
b.If a high/low control has been wired between terminals RC1 and RC2 the burner starts at Low and is released to go High after the flame stabilization period. It can repeatedly cycle between low and high as necessary to meet load demand until the load is satisfied or a limit opens. The burner is then sent to
7.Recycle: If the flame is lost 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 a
8.
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.
