DESCRIPTION
The Fireye SBSeries Flame Safeguard Control is a compact, microprocessor based, modular burner
management system designed to provide automatic ignition and continuous flame monitoring for com-
mercial sizes of heating and process equipment firing any type of fuel.
The SBSeries are tested to EN298.
The control unit includes all the necessary digital logic and analog measuring circuitry to control the
sequence and monitor the flame of single gas, oil or combination gas/oil burners. Three available control
sequences are no-purge, purge, and modulation (air damper control). The part number specifies the
various features such as the flame sensor type, no purge, purge, modulation, proof of air opening at
start, and timings; thus the designer has control and protection against field tampering of critical
sequences.
LED indicators are available on the front of the unit that provide current operating status of the burner
system including lockout alarm. A test jack is recessed into the front cover that provides real time
reading of the connected flame sensor. This same test jack is also used to connect to an alpha-numeric
display, SB20896. A push button provides reset from lockout condition as well as placing the unit in a
check condition usable for pilot turn down test.
The SBSeries flame safeguard control family are of plug-in design and available in models that operate
at 120 VAC, 50/60 Hz and 230 VAC, 50/60 Hz making them universally acceptable.
*The wiring base provides a convenient means for connecting field wiring from the burner and valve
system to the control unit. There are three styles of bases: an internal terminal base that provides a
guarded wiring compartment; an external terminal base for use within a protective control panel; and
an expanded external terminal base for use with the modulation sequence control units.
Sensors that may be used with the SBSeries include flame rod (rectified ionization), ultra-violet (UV)
scanners, and self-checking UV scanners for continuous operation. Four types of non self-checking UV
scanners meet the demands of various environmental conditions.

CAUTION: The SB49600-91 and SB49600-90 ultra-violet flame scanners and associated
amplifier modules are non self-checking UV systems and should be applied only to burners that cycle
often (e.g. a minimum of once per 12 hours) in order for the safety checking circuit to be exercised.
WARNING: Installer must be trained and qualified. Follow the burner manufacturer’s instructions,
if supplied. Otherwise, proceed as follows.

INSTALLATION OF CONTROL, SCANNERS AND FLAME DETECTORS
Wiring Base
Mount the wiring base on the burner or on a panel. The location should be free from excessive vibra-
tion and within the specified ambient temperature rating. The base may be mounted in any angular
position.
All wiring should comply with applicable electrical codes, regulations and local ordinances. Use
moisture resistant wire suitable for at least 90°C. Good electrical wiring practice should be followed
to ensure an adequate ground system. Refer to Fireye Service Note SN-100 separately and General
Grounding Rules later in this document for grounding methods.
A good ground system should be provided to minimize the effects of AC quality problems. A properly
designed ground system meeting all the safety requirements will ensure that any AC voltage quality
problems, such as spikes, surges and impulses have a low impedance path to ground. A low impedance
path to ground is required to ensure that large currents involved with any surge voltages will follow
the desired path in preference to alternative paths, where extensive damage may occur to equipment.
Circuit recommendations are found on pages 11 through 13. Consult the factory for assistance with
non-standard applications.
Care must be taken to NOT route the high energy ignition wire in close proximity to the
flame sensor wiring.
INSTALLATION GUIDELINES
Terminal 7 - Interlocks and Limit Switch Input
Wire external interlock, control, and limit switches in series to this input. Guard against induced
voltage levels to wiring connected to this input. In some extreme wiring runs, reduction of induced
voltages may require a load (relay or light) connected to terminal 7 to avoid system error lockouts.
This input is the power source for the valve and ignition output terminals. Be sure all switches wired
to this input can handle the current required by the total of all loads connected to terminals 3, 4, and
5.
Terminal 6 - Combustion Air Switch Input
For purge and modulation models: Wire any switches and contacts in series to this terminal for
proving airflow function and relating to the air failure light. Power must not be immediately present
at terminal 6 when power is first applied to terminals 1 or 7. If the combustion air blower is
controlled outside of the SBSeries system, then a three-way solenoid valve must be connected
between the air switch port and the blower sensing port. The valve de-energized state should vent
the switch to ambient.
WARNING: Controls require safety limits utilizing isolated mechanical contacts. Electronic limit
switches may cause erratic operation and should be avoided.
