The GeniSysTM 24V is used with a suitable cad cell flame sensor to control the oil burner motor, igniter, and optional solenoid valve. It has 24 volt enable input compatible with mechanical and high limit switches. It can provide interrupted or intermittent duty ignition, and it has a 15 second lockout time on flame failure. Features • Welded Relay Protection • Limited Relight • Valve-On Delay / Motor-Off Delay (Field programmable with Beckett’s Contractor Tool) • 15 Second Lockout Time • Interrupted Ignition • Communication Port • Lockout Alarm Output • Fused Protection Specifications CAUTION Do Not Use This Control in an Application that is Not Within the Ratings Listed in This Section. Improper Control Operation MayResult. CAUTION Do Not Use This Control Above 5.5 GPH Electrical Ratings Inputs: •Voltage: 24 Vdc nominal (21.6 to 30 Vdc) •Current: 220 mA nominal (230 mA max at 30 Vdc)* • Enable Load: 22mA at 24 Vdc Outputs: • Motor: 24 Vdc, 10 full load amps (FLA), 50 locked rotor amps (LRA) •Igniter: 24 Vdc, 3 A •Solenoid Valve: 24 Vdc, 1 A • Lockout Alarm: 24 Vdc, 1A The 7559 control draws 40-55mA in the standby state. If the red control wire is left powered without a battery charging system, it can drain a standard 45 Amp hour automotive battery in four to six weeks. * Environmental Ratings: • Storage and Operating Ambient Temperature: -40°F to +160°F (-40°C to +71°C) • Moisture: 5 to 95% RH, condensing WARNING Maintain Specified Voltage A low or erratic power supply could result in impaired burner operation, severe delayed ignition or an explosioninside the heat exchanger resulting in aburn and/or asphyxiation hazard. • Beckett DC Burners require a continuous supply of 21.6 to 30 volts DC (at 11 amps for Model ADC or 15 amps for Model SDC), measured at the burner during operation. • Consult other DC burner manufacturers’ specifications for the correct voltage range. • Special Note: The 7559 Controlshuts the burner down if the inputvoltage drops to a sustained levelof 20 volts DC, or below. Operation resumes at a sustained inputvoltage of 21 volts DC, or above. • An automotive or small engine charging system that is capable of supplying the required continuous voltage/amperage is recommended with certain road equipment, such as asphalt hot patchers and similar applications. • This is especially true whilemaintaining nominal load temperaturesduring idle periods.

Incorrect installation or misuse of this control could result in severe personal injury or death from heavy smoke, explosion or fire. Please read and understand the manual supplied with this control. This control must be installed, adjusted and put into operation only by a qualified individual or service agency that is: • Licensed or certified to install and provide technical service to oilheating systems. • Experienced with all applicablecodes, standards and ordinances. • Responsible for the correctinstallation and commission of this equipment. • Skilled in the adjustment of oil burners using combustion test instruments. The installation must strictly comply withall applicable codes, authorities havingjurisdiction and the latest revision ofthe National Fire Protection Association Standard for the Installation of Oil-BurningEquipment, NFPA 31 (or CSA-B139 and CSA-B140 in Canada) for stationaryequipment. Regulation by these authorities take precedence over the general instructions provided in this installation manual. WARNING Electrical Shock Hazard Electrical shock can cause severe personal injury or death. • Disconnect ALL electrical power to the equipment/burner circuit before installing or servicing this control. • Provide ground wiring to the equipment, burner and metal control mounting box. • Perform all wiring in compliance with the National Electrical Code ANSI/ NFPA 70 (Canada CSA C22.1). All heating equipment musthave HIGH LIMIT controls to protect against excessivetemperature and/or pressure. The control must interrupt electricalpower and shutdown the burner, if operating or safety controls fail andcause a runaway condition. • Follow the equipment manufacturer’swiring diagrams and note all requiredsafety controls. • Typical safety controls include high temperature or pressure limits, lowwater cutoffs, pressure relief valves and blocked flue sensing switches. • Verify all limit and safety controls are installed and functioning correctly, as specified by the manufacturer, applicable safety...
